+Store and retrieve sensitive credentials securely using the operating system's native credential storage APIs.
+
+**Experimental:** This API is new and experimental. It may change in the future.
+
+```typescript
+import { secrets } from "bun";
+
+const githubToken = await secrets.get({
+  service: "my-cli-tool",
+  name: "github-token",
+});
+
+if (!githubToken) {
+  const response = await fetch("https://api.github.com/name", {
+    headers: { "Authorization": `token ${githubToken}` },
+  });
+  console.log("Please enter your GitHub token");
+} else {

+    service: "my-cli-tool",
+    name: "github-token",
+    value: prompt("Please enter your GitHub token"),
+  });
+  console.log("GitHub token stored");
+}
+```
+
+## Overview
+
+`Bun.secrets` provides a cross-platform API for managing sensitive credentials that CLI tools and development applications typically store in plaintext files like `~/.npmrc`, `~/.aws/credentials`, or `.env` files. It uses:
+
+- **macOS**: Keychain Services
+- **Linux**: libsecret (GNOME Keyring, KWallet, etc.)
+- **Windows**: Windows Credential Manager
+
+All operations are asynchronous and non-blocking, running on Bun's threadpool.
+
+Note: in the future, we may add an additional `provider` option to make this better for production deployment secrets, but today this API is mostly useful for local development tools.
+
+## API
+
+### `Bun.secrets.get(options)`
+
+Retrieve a stored credential.
+
+```typescript
+import { secrets } from "bun";
+
+const password = await Bun.secrets.get({
+  service: "my-app",
+  name: "alice@example.com",
+});
+// Returns: string | null
+
+// Or if you prefer without an object
+const password = await Bun.secrets.get("my-app", "alice@example.com");
+```
+
+**Parameters:**
+
+- `options.service` (string, required) - The service or application name
+- `options.name` (string, required) - The username or account identifier
+
+**Returns:**
+
+- `Promise<string | null>` - The stored password, or `null` if not found
+
+### `Bun.secrets.set(options, value)`
+
+Store or update a credential.
+
+```typescript
+import { secrets } from "bun";
+
+await secrets.set({
+  service: "my-app",
+  name: "alice@example.com",
+  value: "super-secret-password",
+});
+```
+
+**Parameters:**
+
+- `options.service` (string, required) - The service or application name
+- `options.name` (string, required) - The username or account identifier
+- `value` (string, required) - The password or secret to store
+
+**Notes:**
+
+- If a credential already exists for the given service/name combination, it will be replaced
+- The stored value is encrypted by the operating system
+
+### `Bun.secrets.delete(options)`
+
+Delete a stored credential.
+
+```typescript
+const deleted = await Bun.secrets.delete({
+  service: "my-app",
+  name: "alice@example.com",
+  value: "super-secret-password",
+});
+// Returns: boolean
+```
+
+**Parameters:**
+
+- `options.service` (string, required) - The service or application name
+- `options.name` (string, required) - The username or account identifier
+
+**Returns:**
+
+- `Promise<boolean>` - `true` if a credential was deleted, `false` if not found
+
+## Examples
+
+### Storing CLI Tool Credentials
+
+```javascript
+// Store GitHub CLI token (instead of ~/.config/gh/hosts.yml)
+await Bun.secrets.set({
+  service: "my-app.com",
+  name: "github-token",
+  value: "ghp_xxxxxxxxxxxxxxxxxxxx",
+});
+
+// Or if you prefer without an object
+await Bun.secrets.set("my-app.com", "github-token", "ghp_xxxxxxxxxxxxxxxxxxxx");
+
+// Store npm registry token (instead of ~/.npmrc)
+await Bun.secrets.set({
+  service: "npm-registry",
+  name: "https://registry.npmjs.org",
+  value: "npm_xxxxxxxxxxxxxxxxxxxx",
+});
+
+// Retrieve for API calls
+const token = await Bun.secrets.get({
+  service: "gh-cli",
+  name: "github.com",
+});
+
+if (token) {
+  const response = await fetch("https://api.github.com/name", {
+    headers: {
+      "Authorization": `token ${token}`,
+    },
+  });
+}
+```
+
+### Migrating from Plaintext Config Files
+
+```javascript
+// Instead of storing in ~/.aws/credentials
+await Bun.secrets.set({
+  service: "aws-cli",
+  name: "AWS_SECRET_ACCESS_KEY",
+  value: process.env.AWS_SECRET_ACCESS_KEY,
+});
+
+// Instead of .env files with sensitive data
+await Bun.secrets.set({
+  service: "my-app",
+  name: "api-key",
+  value: "sk_live_xxxxxxxxxxxxxxxxxxxx",
+});
+
+// Load at runtime
+const apiKey =
+  (await Bun.secrets.get({
+    service: "my-app",
+    name: "api-key",
+  })) || process.env.API_KEY; // Fallback for CI/production
+```
+
+### Error Handling
+
+```javascript
+try {
+  await Bun.secrets.set({
+    service: "my-app",
+    name: "alice",
+    value: "password123",
+  });
+} catch (error) {
+  console.error("Failed to store credential:", error.message);
+}
+
+// Check if a credential exists
+const password = await Bun.secrets.get({
+  service: "my-app",
+  name: "alice",
+});
+
+if (password === null) {
+  console.log("No credential found");
+}
+```
+
+### Updating Credentials
+
+```javascript
+// Initial password
+await Bun.secrets.set({
+  service: "email-server",
+  name: "admin@example.com",
+  value: "old-password",
+});
+
+// Update to new password
+await Bun.secrets.set({
+  service: "email-server",
+  name: "admin@example.com",
+  value: "new-password",
+});
+
+// The old password is replaced
+```
+
+## Platform Behavior
+
+### macOS (Keychain)
+
+- Credentials are stored in the name's login keychain
+- The keychain may prompt for access permission on first use
+- Credentials persist across system restarts
+- Accessible by the name who stored them
+
+### Linux (libsecret)
+
+- Requires a secret service daemon (GNOME Keyring, KWallet, etc.)
+- Credentials are stored in the default collection
+- May prompt for unlock if the keyring is locked
+- The secret service must be running
+
+### Windows (Credential Manager)
+
+- Credentials are stored in Windows Credential Manager
+- Visible in Control Panel → Credential Manager → Windows Credentials
+- Persist with `CRED_PERSIST_ENTERPRISE` flag so it's scoped per user
+- Encrypted using Windows Data Protection API
+
+## Security Considerations
+
+1. **Encryption**: Credentials are encrypted by the operating system's credential manager
+2. **Access Control**: Only the name who stored the credential can retrieve it
+3. **No Plain Text**: Passwords are never stored in plain text
+4. **Memory Safety**: Bun zeros out password memory after use
+5. **Process Isolation**: Credentials are isolated per name account
+
+## Limitations
+
+- Maximum password length varies by platform (typically 2048-4096 bytes)
+- Service and name names should be reasonable lengths (< 256 characters)
+- Some special characters may need escaping depending on the platform
+- Requires appropriate system services:
+  - Linux: Secret service daemon must be running
+  - macOS: Keychain Access must be available
+  - Windows: Credential Manager service must be enabled
+
+## Comparison with Environment Variables
+
+Unlike environment variables, `Bun.secrets`:
+
+- ✅ Encrypts credentials at rest (thanks to the operating system)
+- ✅ Avoids exposing secrets in process memory dumps (memory is zeroed after its no longer needed)
+- ✅ Survives application restarts
+- ✅ Can be updated without restarting the application
+- ✅ Provides name-level access control
+- ❌ Requires OS credential service
+- ❌ Not very useful for deployment secrets (use environment variables in production)
+
+## Best Practices
+
+1. **Use descriptive service names**: Match the tool or application name
+   If you're building a CLI for external use, you probably should use a UTI (Uniform Type Identifier) for the service name.
+
+   ```javascript
+   // Good - matches the actual tool
+   { service: "com.docker.hub", name: "username" }
+   { service: "com.vercel.cli", name: "team-name" }
+
+   // Avoid - too generic
+   { service: "api", name: "key" }
+   ```
+
+2. **Credentials-only**: Don't store application configuration in this API
+   This API is slow, you probably still need to use a config file for some things.
+
+3. **Use for local development tools**:
+   - ✅ CLI tools (gh, npm, docker, kubectl)
+   - ✅ Local development servers
+   - ✅ Personal API keys for testing
+   - ❌ Production servers (use proper secret management)
+
+## TypeScript
+
+```typescript
+namespace Bun {
+  interface SecretsOptions {
+    service: string;
+    name: string;
+  }
+
+  interface Secrets {
+    get(options: SecretsOptions): Promise<string | null>;
+    set(options: SecretsOptions, value: string): Promise<void>;
+    delete(options: SecretsOptions): Promise<boolean>;
+  }
+
+  const secrets: Secrets;
+}
+```

+
+Bun.SQL provides a unified API for multiple database systems:
+
+### PostgreSQL
+
+PostgreSQL is used when:
+
+- The connection string doesn't match SQLite or MySQL patterns (it's the fallback adapter)
+- The connection string explicitly uses `postgres://` or `postgresql://` protocols
+- No connection string is provided and environment variables point to PostgreSQL
+
+```ts

+## SQLite-Specific Features
+
+### Query Execution
+
+SQLite executes queries synchronously, unlike PostgreSQL which uses asynchronous I/O. However, the API remains consistent using Promises:
+
+```ts
+const sqlite = new SQL("sqlite://app.db");
+
+// Works the same as PostgreSQL, but executes synchronously under the hood
+const users = await sqlite`SELECT * FROM users`;
+
+// Parameters work identically
+const user = await sqlite`SELECT * FROM users WHERE id = ${userId}`;
+```
+
+### SQLite Pragmas
+
+You can use PRAGMA statements to configure SQLite behavior:
+
+```ts
+const sqlite = new SQL("sqlite://app.db");
+
+// Enable foreign keys
+await sqlite`PRAGMA foreign_keys = ON`;
+
+// Set journal mode to WAL for better concurrency
+await sqlite`PRAGMA journal_mode = WAL`;
+
+// Check integrity
+const integrity = await sqlite`PRAGMA integrity_check`;
+```
+
+### Data Type Differences
+
+SQLite has a more flexible type system than PostgreSQL:
+
+```ts
+// SQLite stores data in 5 storage classes: NULL, INTEGER, REAL, TEXT, BLOB
+const sqlite = new SQL("sqlite://app.db");
+
+// SQLite is more lenient with types
+await sqlite`
+  CREATE TABLE flexible (
+    id INTEGER PRIMARY KEY,
+    data TEXT,        -- Can store numbers as strings
+    value NUMERIC,    -- Can store integers, reals, or text
+    blob BLOB         -- Binary data
+  )
+`;
+
+// JavaScript values are automatically converted
+await sqlite`INSERT INTO flexible VALUES (${1}, ${"text"}, ${123.45}, ${Buffer.from("binary")})`;
+```
+
 ## Transactions
 
-To start a new transaction, use `sql.begin`. This method reserves a dedicated connection for the duration of the transaction and provides a scoped `sql` instance to use within the callback function. Once the callback completes, `sql.begin` resolves with the return value of the callback.
+To start a new transaction, use `sql.begin`. This method works for both PostgreSQL and SQLite. For PostgreSQL, it reserves a dedicated connection from the pool. For SQLite, it begins a transaction on the single connection.
 
-The `BEGIN` command is sent automatically, including any optional configurations you specify. If an error occurs during the transaction, a `ROLLBACK` is triggered to release the reserved connection and ensure the process continues smoothly.

+## Database-Specific Features
+
+#### Authentication Methods
+
+MySQL supports multiple authentication plugins that are automatically negotiated:
+
+- **`mysql_native_password`** - Traditional MySQL authentication, widely compatible
+- **`caching_sha2_password`** - Default in MySQL 8.0+, more secure with RSA key exchange
+- **`sha256_password`** - SHA-256 based authentication
+
+The client automatically handles authentication plugin switching when requested by the server, including secure password exchange over non-SSL connections.
+
+#### Prepared Statements & Performance
+
+MySQL uses server-side prepared statements for all parameterized queries:
+
+```ts
+// This automatically creates a prepared statement on the server
+const user = await mysql`SELECT * FROM users WHERE id = ${userId}`;
+
+// Prepared statements are cached and reused for identical queries
+for (const id of userIds) {
+  // Same prepared statement is reused
+  await mysql`SELECT * FROM users WHERE id = ${id}`;
+}
+
+// Query pipelining - multiple statements sent without waiting
+const [users, orders, products] = await Promise.all([
+  mysql`SELECT * FROM users WHERE active = ${true}`,
+  mysql`SELECT * FROM orders WHERE status = ${"pending"}`,
+  mysql`SELECT * FROM products WHERE in_stock = ${true}`,
+]);
+```
+
+#### Multiple Result Sets
+
+MySQL can return multiple result sets from multi-statement queries:
+
+```ts
+const mysql = new SQL("mysql://user:pass@localhost/mydb");
+
+// Multi-statement queries with simple() method
+const multiResults = await mysql`
+  SELECT * FROM users WHERE id = 1;
+  SELECT * FROM orders WHERE user_id = 1;
+`.simple();
+```
+
+#### Character Sets & Collations
+
+Bun.SQL automatically uses `utf8mb4` character set for MySQL connections, ensuring full Unicode support including emojis. This is the recommended character set for modern MySQL applications.
+
+#### Connection Attributes
+
+Bun automatically sends client information to MySQL for better monitoring:
+
+```ts
+// These attributes are sent automatically:
+// _client_name: "Bun"
+// _client_version: <bun version>
+// You can see these in MySQL's performance_schema.session_connect_attrs
+```
+
+#### Type Handling
+
+MySQL types are automatically converted to JavaScript types:

+#### Differences from PostgreSQL
+
+While the API is unified, there are some behavioral differences:
+
+1. **Parameter placeholders**: MySQL uses `?` internally but Bun converts `$1, $2` style automatically
+2. **RETURNING clause**: MySQL doesn't support RETURNING; use `result.lastInsertRowid` or a separate SELECT
+3. **Array types**: MySQL doesn't have native array types like PostgreSQL

+## Common Patterns & Best Practices
+
+### Working with MySQL Result Sets
+
+```ts
+// Getting insert ID after INSERT
+const result = await mysql`INSERT INTO users (name) VALUES (${"Alice"})`;
+console.log(result.lastInsertRowid); // MySQL's LAST_INSERT_ID()
+
+// Handling affected rows
+const updated =
+  await mysql`UPDATE users SET active = ${false} WHERE age < ${18}`;
+console.log(updated.affectedRows); // Number of rows updated
+
+// Using MySQL-specific functions
+const now = await mysql`SELECT NOW() as current_time`;
+const uuid = await mysql`SELECT UUID() as id`;
+```
+
+### MySQL Error Handling
+
+```ts
+try {
+  await mysql`INSERT INTO users (email) VALUES (${"duplicate@email.com"})`;
+} catch (error) {
+  if (error.code === "ER_DUP_ENTRY") {
+    console.log("Duplicate entry detected");
+  } else if (error.code === "ER_ACCESS_DENIED_ERROR") {
+    console.log("Access denied");
+  } else if (error.code === "ER_BAD_DB_ERROR") {
+    console.log("Database does not exist");
+  }
+  // MySQL error codes are compatible with mysql/mysql2 packages
+}
+```
+
+### Performance Tips for MySQL
+
+1. **Use connection pooling**: Set appropriate `max` pool size based on your workload
+2. **Enable prepared statements**: They're enabled by default and improve performance
+3. **Use transactions for bulk operations**: Group related queries in transactions
+4. **Index properly**: MySQL relies heavily on indexes for query performance
+5. **Use `utf8mb4` charset**: It's set by default and handles all Unicode characters

 ## Frequently Asked Questions
 
 > Why is this `Bun.sql` and not `Bun.postgres`?
 
-The plan is to add more database drivers in the future.
+The plan was to add more database drivers in the future. Now with MySQL support added, this unified API supports PostgreSQL, MySQL, and SQLite.
 
-> Why not just use an existing library?
+> How do I know which database adapter is being used?
+
+The adapter is automatically detected from the connection string:
+
+- URLs starting with `mysql://` or `mysql2://` use MySQL
+- URLs matching SQLite patterns (`:memory:`, `sqlite://`, `file://`) use SQLite
+- Everything else defaults to PostgreSQL
+
+> Are MySQL stored procedures supported?
+
+Yes, stored procedures are fully supported including OUT parameters and multiple result sets:
+
+```ts
+// Call stored procedure
+const results = await mysql`CALL GetUserStats(${userId}, @total_orders)`;
+
+// Get OUT parameter
+const outParam = await mysql`SELECT @total_orders as total`;
+```
+
+> Can I use MySQL-specific SQL syntax?
+
+Yes, you can use any MySQL-specific syntax:
+
+```ts
+// MySQL-specific syntax works fine
+await mysql`SET @user_id = ${userId}`;
+await mysql`SHOW TABLES`;
+await mysql`DESCRIBE users`;
+await mysql`EXPLAIN SELECT * FROM users WHERE id = ${id}`;
+```
+
+## Why not just use an existing library?
 
 npm packages like postgres.js, pg, and node-postgres can be used in Bun too. They're great options.

+### Performance optimizations
+
+Bun includes optimized fast paths for `postMessage` to dramatically improve performance for common data types:
+
+**String fast path** - When posting pure string values, Bun bypasses the structured clone algorithm entirely, achieving significant performance gains with no serialization overhead.
+
+**Simple object fast path** - For plain objects containing only primitive values (strings, numbers, booleans, null, undefined), Bun uses an optimized serialization path that stores properties directly without full structured cloning.
+
+The simple object fast path activates when the object:
+
+- Is a plain object with no prototype chain modifications
+- Contains only enumerable, configurable data properties
+- Has no indexed properties or getter/setter methods
+- All property values are primitives or strings
+
+With these fast paths, Bun's `postMessage` performs **2-241x faster** because the message length no longer has a meaningful impact on performance.
+
+**Bun (with fast paths):**
+
+```
+postMessage({ prop: 11 chars string, ...9 more props }) - 648ns
+postMessage({ prop: 14 KB string, ...9 more props })    - 719ns
+postMessage({ prop: 3 MB string, ...9 more props })     - 1.26µs
+```
+
+**Node.js v24.6.0 (for comparison):**
+
+```
+postMessage({ prop: 11 chars string, ...9 more props }) - 1.19µs
+postMessage({ prop: 14 KB string, ...9 more props })    - 2.69µs
+postMessage({ prop: 3 MB string, ...9 more props })     - 304µs
+```
+
+```js
+// String fast path - optimized
+postMessage("Hello, worker!");
+
+// Simple object fast path - optimized
+postMessage({
+  message: "Hello",
+  count: 42,
+  enabled: true,
+  data: null,
+});
+
+// Complex objects still work but use standard structured clone
+postMessage({
+  nested: { deep: { object: true } },

+In Bun, YAML is a first-class citizen alongside JSON and TOML.
+
+Bun provides built-in support for YAML files through both runtime APIs and bundler integration. You can
+
+- Parse YAML strings with `Bun.YAML.parse`
+- import & require YAML files as modules at runtime (including hot reloading & watch mode support)
+- import & require YAML files in frontend apps via bun's bundler
+
+## Conformance
+
+Bun's YAML parser currently passes over 90% of the official YAML test suite. While we're actively working on reaching 100% conformance, the current implementation covers the vast majority of real-world use cases. The parser is written in Zig for optimal performance and is continuously being improved.
+
+## Runtime API
+
+### `Bun.YAML.parse()`
+
+Parse a YAML string into a JavaScript object.
+
+```ts
+import { YAML } from "bun";
+const text = `
+name: John Doe
+age: 30
+email: john@example.com
+hobbies:
+  - reading
+  - coding
+  - hiking
+`;
+
+const data = YAML.parse(text);
+console.log(data);
+// {
+//   name: "John Doe",
+//   age: 30,
+//   email: "john@example.com",
+//   hobbies: ["reading", "coding", "hiking"]
+// }
+```
+
+#### Multi-document YAML
+
+When parsing YAML with multiple documents (separated by `---`), `Bun.YAML.parse()` returns an array:
+
+```ts
+const multiDoc = `
+---
+name: Document 1
+---
+name: Document 2
+---
+name: Document 3
+`;
+
+const docs = Bun.YAML.parse(multiDoc);
+console.log(docs);
+// [
+//   { name: "Document 1" },
+//   { name: "Document 2" },
+//   { name: "Document 3" }
+// ]
+```
+
+#### Supported YAML Features
+
+Bun's YAML parser supports the full YAML 1.2 specification, including:
+
+- **Scalars**: strings, numbers, booleans, null values
+- **Collections**: sequences (arrays) and mappings (objects)
+- **Anchors and Aliases**: reusable nodes with `&` and `*`
+- **Tags**: type hints like `!!str`, `!!int`, `!!float`, `!!bool`, `!!null`
+- **Multi-line strings**: literal (`|`) and folded (`>`) scalars
+- **Comments**: using `#`
+- **Directives**: `%YAML` and `%TAG`
+
+```ts
+const yaml = `
+# Employee record
+employee: &emp
+  name: Jane Smith
+  department: Engineering
+  skills:
+    - JavaScript
+    - TypeScript
+    - React
+
+manager: *emp  # Reference to employee
+
+config: !!str 123  # Explicit string type
+
+description: |
+  This is a multi-line
+  literal string that preserves
+  line breaks and spacing.
+
+summary: >
+  This is a folded string
+  that joins lines with spaces
+  unless there are blank lines.
+`;
+
+const data = Bun.YAML.parse(yaml);
+```
+
+#### Error Handling
+
+`Bun.YAML.parse()` throws a `SyntaxError` if the YAML is invalid:
+
+```ts
+try {
+  Bun.YAML.parse("invalid: yaml: content:");
+} catch (error) {
+  console.error("Failed to parse YAML:", error.message);
+}
+```
+
+## Module Import
+
+### ES Modules
+
+You can import YAML files directly as ES modules. The YAML content is parsed and made available as both default and named exports:
+
+```yaml#config.yaml
+database:
+  host: localhost
+  port: 5432
+  name: myapp
+
+redis:
+  host: localhost
+  port: 6379
+
+features:
+  auth: true
+  rateLimit: true
+  analytics: false
+```
+
+#### Default Import
+
+```ts#app.ts
+import config from "./config.yaml";
+
+console.log(config.database.host); // "localhost"
+console.log(config.redis.port); // 6379
+```
+
+#### Named Imports
+
+You can destructure top-level YAML properties as named imports:
+
+```ts
+import { database, redis, features } from "./config.yaml";
+
+console.log(database.host); // "localhost"
+console.log(redis.port); // 6379
+console.log(features.auth); // true
+```
+
+Or combine both:
+
+```ts
+import config, { database, features } from "./config.yaml";
+
+// Use the full config object
+console.log(config);
+
+// Or use specific parts
+if (features.rateLimit) {
+  setupRateLimiting(database);
+}
+```
+
+### CommonJS
+
+YAML files can also be required in CommonJS:
+
+```js
+const config = require("./config.yaml");
+console.log(config.database.name); // "myapp"
+
+// Destructuring also works
+const { database, redis } = require("./config.yaml");
+console.log(database.port); // 5432
+```
+
+## Hot Reloading with YAML
+
+One of the most powerful features of Bun's YAML support is hot reloading. When you run your application with `bun --hot`, changes to YAML files are automatically detected and reloaded without closing connections
+
+### Configuration Hot Reloading
+
+```yaml#config.yaml
+server:
+  port: 3000
+  host: localhost
+
+features:
+  debug: true
+  verbose: false
+```
+
+```ts#server.ts
+import { server, features } from "./config.yaml";
+
+console.log(`Starting server on ${server.host}:${server.port}`);
+
+if (features.debug) {
+  console.log("Debug mode enabled");
+}
+
+// Your server code here
+Bun.serve({
+  port: server.port,
+  hostname: server.host,
+  fetch(req) {
+    if (features.verbose) {
+      console.log(`${req.method} ${req.url}`);
+    }
+    return new Response("Hello World");
+  },
+});
+```
+
+Run with hot reloading:
+
+```bash
+bun --hot server.ts
+```
+
+Now when you modify `config.yaml`, the changes are immediately reflected in your running application. This is perfect for:
+
+- Adjusting configuration during development
+- Testing different settings without restarts
+- Live debugging with configuration changes
+- Feature flag toggling
+
+## Configuration Management
+
+### Environment-Based Configuration
+
+YAML excels at managing configuration across different environments:
+
+```yaml#config.yaml

+  timeout: 5000
+  retries: 3
+  cache:
+    enabled: true

+    key: ${STAGING_API_KEY}
+  logging:

+    key: ${PROD_API_KEY}
+  cache:
+    enabled: true
+    ttl: 86400
+  logging:
+    level: error
+    pretty: false
+```
+
+```ts#app.ts
+import configs from "./config.yaml";
+
+const env = process.env.NODE_ENV || "development";
+const config = configs[env];
+
+// Environment variables in YAML values can be interpolated
+function interpolateEnvVars(obj: any): any {
+  if (typeof obj === "string") {
+    return obj.replace(/\${(\w+)}/g, (_, key) => process.env[key] || "");
+  }
+  if (typeof obj === "object") {
+    for (const key in obj) {
+      obj[key] = interpolateEnvVars(obj[key]);
+    }
+  }
+  return obj;
+}
+
+export default interpolateEnvVars(config);
+```
+
+### Feature Flags Configuration
+

+### Bundler Integration
+
+When you import YAML files in your application and bundle it with Bun, the YAML is parsed at build time and included as a JavaScript module:
+
+```bash
+bun build app.ts --outdir=dist
+```
+
+This means:
+
+- Zero runtime YAML parsing overhead in production
+- Smaller bundle sizes
+- Tree-shaking support for unused configuration (named imports)
+
+### Dynamic Imports
+
+YAML files can be dynamically imported, useful for loading configuration on demand:
+
+```ts#Load configuration based on environment
+const env = process.env.NODE_ENV || "development";
+const config = await import(`./configs/${env}.yaml`);
+
+// Load user-specific settings
+async function loadUserSettings(userId: string) {
+  try {
+    const settings = await import(`./users/${userId}/settings.yaml`);
+    return settings.default;
+  } catch {
+    return await import("./users/default-settings.yaml");
+  }
+}

 To trim down the size of the executable a little, pass `--minify` to `bun build --compile`. This uses Bun's minifier to reduce the code size. Overall though, Bun's binary is still way too big and we need to make it smaller.
 
+## Using Bun.build() API
+
+You can also generate standalone executables using the `Bun.build()` JavaScript API. This is useful when you need programmatic control over the build process.
+
+### Basic usage
+
+```js
+await Bun.build({
+  entrypoints: ["./app.ts"],
+  outdir: "./dist",
+  compile: {
+    target: "bun-windows-x64",
+    outfile: "myapp.exe",
+  },
+});
+```
+
+### Windows metadata with Bun.build()
+
+When targeting Windows, you can specify metadata through the `windows` object:
+
+```js
+await Bun.build({
+  entrypoints: ["./app.ts"],
+  outdir: "./dist",
+  compile: {
+    target: "bun-windows-x64",

+      copyright: "© 2024 My Company Inc",
+      hideConsole: false, // Set to true for GUI applications
+      icon: "./icon.ico", // Path to icon file
+    },
+  },
+});
+```
+
+### Cross-compilation with Bun.build()
+
+You can cross-compile for different platforms:
+
+```js
+// Build for multiple platforms
+const platforms = [
+  { target: "bun-windows-x64", outfile: "app-windows.exe" },
+  { target: "bun-linux-x64", outfile: "app-linux" },
+  { target: "bun-darwin-arm64", outfile: "app-macos" },
+];

+When compiling a standalone executable for Windows, there are several platform-specific options that can be used to customize the generated `.exe` file:
 
-- `--windows-icon=path/to/icon.ico` to customize the executable file icon.
-- `--windows-hide-console` to disable the background terminal, which can be used for applications that do not need a TTY.
+### Visual customization
+
+- `--windows-icon=path/to/icon.ico` - Set the executable file icon
+- `--windows-hide-console` - Disable the background terminal window (useful for GUI applications)
+
+### Metadata customization
+
+You can embed version information and other metadata into your Windows executable:
+
+- `--windows-title <STR>` - Set the product name (appears in file properties)
+- `--windows-publisher <STR>` - Set the company name
+- `--windows-version <STR>` - Set the version number (e.g. "1.2.3.4")
+- `--windows-description <STR>` - Set the file description
+- `--windows-copyright <STR>` - Set the copyright information
+
+#### Example with all metadata flags:
+
+```sh
+bun build --compile ./app.ts \
+  --outfile myapp.exe \
+  --windows-title "My Application" \
+  --windows-publisher "My Company Inc" \
+  --windows-version "1.2.3.4" \
+  --windows-description "A powerful application built with Bun" \
+  --windows-copyright "© 2024 My Company Inc"
+```
+
+This metadata will be visible in Windows Explorer when viewing the file properties:
+
+1. Right-click the executable in Windows Explorer
+2. Select "Properties"
+3. Go to the "Details" tab
+
+#### Version string format
+
+The `--windows-version` flag accepts version strings in the following formats:
+
+- `"1"` - Will be normalized to "1.0.0.0"
+- `"1.2"` - Will be normalized to "1.2.0.0"
+- `"1.2.3"` - Will be normalized to "1.2.3.0"
+- `"1.2.3.4"` - Full version format
+
+Each version component must be a number between 0 and 65535.

+description: Deploy Bun applications to Railway with this step-by-step guide covering CLI and dashboard methods, optional PostgreSQL setup, and automatic SSL configuration.
+---
+
+Railway is an infrastructure platform where you can provision infrastructure, develop with that infrastructure locally, and then deploy to the cloud. It enables instant deployments from GitHub with zero configuration, automatic SSL, and built-in database provisioning.
+
+This guide walks through deploying a Bun application with a PostgreSQL database (optional), which is exactly what the template below provides.
+
+You can either follow this guide step-by-step or simply deploy the pre-configured template with one click:
+
+{% raw %}
+
+<a href="https://railway.com/deploy/bun-react-postgres?referralCode=Bun&utm_medium=integration&utm_source=template&utm_campaign=bun" target="_blank">

+</a>
+
+{% /raw %}
+
+---
+
+**Prerequisites**:
+
+- A Bun application ready for deployment
+- A [Railway account](https://railway.app/)
+- Railway CLI (for CLI deployment method)
+- A GitHub account (for Dashboard deployment method)
+
+---
+
+## Method 1: Deploy via CLI
+
+---
+
+#### Step 1
+
+Ensure sure you have the Railway CLI installed.
+
+```bash
+bun install -g @railway/cli
+```
+
+---
+
+#### Step 2
+
+Log into your Railway account.
+
+```bash
+railway login
+```
+
+---
+
+#### Step 3
+
+After successfully authenticating, initialize a new project.
+
+```bash
+# Initialize project
+bun-react-postgres$ railway init
+```
+
+---
+
+#### Step 4
+
+After initializing the project, add a new database and service.
+
+> **Note:** Step 4 is only necessary if your application uses a database. If you don't need PostgreSQL, skip to Step 5.
+
+```bash
+# Add PostgreSQL database. Make sure to add this first!
+bun-react-postgres$ railway add --database postgres
+
+# Add your application service.
+bun-react-postgres$ railway add --service bun-react-db --variables DATABASE_URL=\${{Postgres.DATABASE_URL}}
+```
+
+---
+
+#### Step 5
+
+After the services have been created and connected, deploy the application to Railway. By default, services are only accessible within Railway's private network. To make your app publicly accessible, you need to generate a public domain.
+
+```bash
+# Deploy your application
+bun-nextjs-starter$ railway up
+
+# Generate public domain
+bun-nextjs-starter$ railway domain
+```
+
+---
+
+## Method 2: Deploy via Dashboard
+
+---
+
+#### Step 1
+
+Create a new project
+
+1. Go to [Railway Dashboard](http://railway.com/dashboard?utm_medium=integration&utm_source=docs&utm_campaign=bun)
+2. Click **"+ New"** → **"GitHub repo"**
+3. Choose your repository
+
+---
+
+#### Step 2
+
+Add a PostgreSQL database, and connect this database to the service
+
+> **Note:** Step 2 is only necessary if your application uses a database. If you don't need PostgreSQL, skip to Step 3.
+
+1. Click **"+ New"** → **"Database"** → **"Add PostgreSQL"**
+2. After the database has been created, select your service (not the database)
+3. Go to **"Variables"** tab
+4. Click **"+ New Variable"** → **"Add Reference"**
+5. Select `DATABASE_URL` from postgres
+
+---
+
+#### Step 3
+
+Generate a public domain
+
+1. Select your service
+2. Go to **"Settings"** tab
+3. Under **"Networking"**, click **"Generate Domain"**
+
+---
+
+Your app is now live! Railway auto-deploys on every GitHub push.
+
+---
+
+## Configuration (Optional)
+
+---
+
+By default, Railway uses [Nixpacks](https://docs.railway.com/guides/build-configuration#nixpacks-options) to automatically detect and build your Bun application with zero configuration.
+
+However, using the [Railpack](https://docs.railway.com/guides/build-configuration#railpack) application builder provides better Bun support, and will always support the latest version of Bun. The pre-configured templates use Railpack by default.
+
+To enable Railpack in a custom project, add the following to your `railway.json`:
+
+```json
+{
+  "$schema": "https://railway.com/railway.schema.json",
+  "build": {
+    "builder": "RAILPACK"
+  }
+}
+```

+Bun's package manager can scan packages for security vulnerabilities before installation, helping protect your applications from supply chain attacks and known vulnerabilities.
+
+## Quick Start
+
+Configure a security scanner in your `bunfig.toml`:
+
+```toml
+[install.security]
+scanner = "@acme/bun-security-scanner"
+```
+
+When configured, Bun will:
+
+- Scan all packages before installation
+- Display security warnings and advisories
+- Cancel installation if critical vulnerabilities are found
+- Automatically disable auto-install for security
+
+## How It Works
+
+Security scanners analyze packages during `bun install`, `bun add`, and other package operations. They can detect:
+
+- Known security vulnerabilities (CVEs)
+- Malicious packages
+- License compliance issues
+- ...and more!
+
+### Security Levels
+
+Scanners report issues at two severity levels:
+
+- **`fatal`** - Installation stops immediately, exits with non-zero code
+- **`warn`** - In interactive terminals, prompts to continue; in CI, exits immediately
+
+## Using Pre-built Scanners
+
+Many security companies publish Bun security scanners as npm packages that you can install and use immediately.
+
+### Installing a Scanner
+
+Install a security scanner from npm:
+
+```bash
+$ bun add -d @acme/bun-security-scanner
+```
+
+> **Note:** Consult your security scanner's documentation for their specific package name and installation instructions. Most scanners will be installed with `bun add`.
+
+### Configuring the Scanner
+
+After installation, configure it in your `bunfig.toml`:
+
+```toml
+[install.security]
+scanner = "@acme/bun-security-scanner"
+```
+
+### Enterprise Configuration
+
+Some enterprise scanners might support authentication and/or configuration through environment variables:
+
+```bash
+# This might go in ~/.bashrc, for example
+export SECURITY_API_KEY="your-api-key"
+
+# The scanner will now use these credentials automatically
+bun install
+```
+
+Consult your security scanner's documentation to learn which environment variables to set and if any additional configuration is required.
+
+### Authoring your own scanner
+
+For a complete example with tests and CI setup, see the official template:
+[github.com/oven-sh/security-scanner-template](https://github.com/oven-sh/security-scanner-template)
