3af0d23d53 docs: expand single-file executable file embedding documentation (#25408)
## Summary

- Expanded documentation for embedding files in single-file executables
with `with { type: "file" }`
- Added clear explanation of how the import attribute works and path
transformation at build time
- Added examples for reading embedded files with both `Bun.file()` and
Node.js `fs` APIs
- Added practical examples: JSON configs, HTTP static assets, templates,
binary files (WASM, fonts)
- Improved `Bun.embeddedFiles` section with a dynamic asset server
example

## Test plan

- [x] Verified all code examples compile and run correctly with `bun
build --compile`
- [x] Tested `Bun.file()` reads embedded files correctly
- [x] Tested `node:fs` APIs (`readFileSync`, `promises.readFile`,
`stat`) work with embedded files
- [x] Tested `Bun.embeddedFiles` returns correct blob array
- [x] Tested `--asset-naming` flag removes content hashes

b80cb629c6 fix(docs): correct mock documentation examples (#25384)
## Summary

- Fix `mock.mock.args` to `mock.mock.calls` in mock-functions.mdx (the

functions (calling spy functions after restore returns `undefined`)
- Add missing `vi` import in Vitest compatibility example

## Test plan

- [x] Verified each code block works by running tests against the debug
build

1006a4fac2 Fix incorrect file name in React component test example 🌟 (#25167)
# What does this PR do?

Nyaa~ This PR fixes a small mistake in the documentation where the code
block for a React component test example was using the wrong filename!
(;ω;)💦

It was previously labeled as `matchers.d.ts`, but it should be something
like `myComponent.test.tsx` to properly reflect a test file for a React
component using `@testing-library/react`. 🧁

This makes the example clearer and more accurate for developers using
Bun to test their React components~! 💻🌸💕

# How did you verify your code works?

It's just docs, one single line 🥺

Pwease review and merge it when you can, senpai~~! UwU 🌈🫧

## Summary

- Add documentation for the `env` option that inlines `process.env.*`
values in frontend code when bundling HTML files
- Document runtime configuration via `bunfig.toml` `[serve.static]`
section for `bun ./index.html`
- Document production build configuration via CLI (`--env=PUBLIC_*`) and
`Bun.build` API (`env: "PUBLIC_*"`)
- Explain prefix filtering to avoid exposing sensitive environment
variables

## Test plan

- [x] Verify documentation renders correctly in local preview
- [x] Cross-reference with existing `env` documentation in
bundler/index.mdx

908ab9ce30 feat(fetch): add proxy object format with headers support (#25090)
## Summary

- Extends `fetch()` proxy option to accept an object format: `proxy: {
url: string, headers?: Headers }`
- Allows sending custom headers to the proxy server (useful for proxy
authentication, custom routing headers, etc.)
- Headers are sent in CONNECT requests (for HTTPS targets) and direct
proxy requests (for HTTP targets)
- User-provided `Proxy-Authorization` header overrides auto-generated
credentials from URL

## Usage

```typescript
// Old format (still works)
fetch(url, { proxy: "http://proxy.example.com:8080" });

// New object format with headers
fetch(url, {
  proxy: {
    url: "http://proxy.example.com:8080",
    headers: {
      "Proxy-Authorization": "Bearer token",
      "X-Custom-Proxy-Header": "value"
    }
  }
});
```

## Test plan

- [x] Test proxy object with url string works same as string proxy
- [x] Test proxy object with headers sends headers to proxy (HTTP
target)
- [x] Test proxy object with headers sends headers in CONNECT request
(HTTPS target)
- [x] Test proxy object with Headers instance
- [x] Test proxy object with empty headers
- [x] Test proxy object with undefined headers
- [x] Test user-provided Proxy-Authorization overrides URL credentials
- [x] All existing proxy tests pass (25 total)

7ec1aa8c95 docs: document new features from v1.3.2 and v1.3.3 (#24932)
## What does this PR do?

Adds missing documentation for features introduced in Bun v1.3.2 and
v1.3.3:

- **Standalone executable config flags**
(`docs/bundler/executables.mdx`): Document
`--no-compile-autoload-dotenv` and `--no-compile-autoload-bunfig` flags
that control automatic config file loading in compiled binaries
- **Test retry/repeats** (`docs/test/writing-tests.mdx`): Document the
`retry` and `repeats` test options for handling flaky tests
- **Disable env file loading**
(`docs/runtime/environment-variables.mdx`): Document `--no-env-file`
flag and `env = false` bunfig option

## How did you verify your code works?

- [x] Verified documentation is accurate against source code
implementation in `src/cli/Arguments.zig`
- [x] Verified features are not already documented elsewhere
- [x] Cross-referenced with v1.3.2 and v1.3.3 release notes

65a215bb4e docs(watch): use relativePath parameter name in recursive example (#24716)
This updates the documentation for `fs.watch()` to use `relativePath`
instead of `filename` in the recursive example, following the same
convention from PR #23990.

When `recursive: true` is set on `fs.watch()`, the callback receives a
relative path to the changed file rather than just a simple filename.
Using `relativePath` as the parameter name makes this distinction
clearer to users.

0c42b46af3 docs: remove outdated version mentions (1.0.x and 1.1.x) (#24570)
## Summary

Remove outdated version mentions (1.0.x and 1.1.x) from documentation
for better consistency. These versions are over a year old - you should
be using a recent version of bun :).

## What changed

**Removed version mentions from:**
- `docs/pm/lifecycle.mdx` - v1.0.16 (trusted dependencies)
- `docs/bundler/executables.mdx` - v1.0.23, v1.1.25, v1.1.30 (various
features)
- `docs/guides/install/jfrog-artifactory.mdx` - v1.0.3+ (env var
comment)
- `docs/guides/install/azure-artifacts.mdx` - v1.0.3+ (env var comment)
- `docs/runtime/workers.mdx` - v1.1.13, v1.1.35 (blob URLs, preload)
- `docs/runtime/networking/dns.mdx` - v1.1.9 (DNS caching)
- `docs/guides/runtime/import-html.mdx` - v1.1.5
- `docs/guides/runtime/define-constant.mdx` - v1.1.5
- `docs/runtime/sqlite.mdx` - v1.1.31

**Kept version mentions in:**
- All 1.2.x versions (still recent, less than a year old)
- Benchmark version numbers (e.g., S3 performance comparison with
v1.1.44)
- `docs/guides/install/yarnlock.mdx` (bun.lock introduction context)
- `docs/project/building-windows.mdx` (build requirements)
- `docs/runtime/http/websockets.mdx` (performance benchmarks)

## Why

The docs lack consistency around version mentions - we don't document
every feature's version, so keeping scattered old version numbers looks
inconsistent. These changes represent a small percentage of features
added recently, and users on ancient versions have bigger problems than
needing to know exactly when a feature landed.

 Bun provides an alternative package installation strategy called **isolated installs** that creates strict dependency isolation similar to pnpm's approach. This mode prevents phantom dependencies and ensures reproducible, deterministic builds.
 
-This is the default installation strategy for monorepo projects.
+This is the default installation strategy for **new** workspace/monorepo projects (with `configVersion = 1` in the lockfile). Existing projects continue using hoisted installs unless explicitly configured.

 ### Default behavior
 
-- For monorepo projects, Bun uses the **isolated** installation strategy by default.
-- For single-project projects, Bun uses the **hoisted** installation strategy by default.
+The default linker strategy depends on your project's lockfile `configVersion`:
+
+| `configVersion` | Using workspaces? | Default Linker |
+| --------------- | ----------------- | -------------- |
+| `1`             |                 | `isolated`     |
+| `1`             |                 | `hoisted`      |
+| `0`             |                 | `hoisted`      |
+| `0`             |                 | `hoisted`      |
+
+**New projects**: Default to `configVersion = 1`. In workspaces, v1 uses the isolated linker by default; otherwise it uses hoisted linking.
+
+**Existing Bun projects (made pre-v1.3.2)**: If your existing lockfile doesn't have a version yet, Bun sets `configVersion = 0` when you run `bun install`, preserving the previous hoisted linker default.
+
+**Migrations from other package managers**:
+
+- From pnpm: `configVersion = 1` (using isolated installs in workspaces)
+- From npm or yarn: `configVersion = 0` (using hoisted installs)
 
 You can override the default behavior by explicitly specifying the `--linker` flag or setting it in your configuration file.

b4f85c8866 Update docs example versions to 1.3.2 (#24522)
## Summary

Updated all example version placeholders in documentation from 1.3.1 and
1.2.20 to 1.3.2.

## Changes

Updated version examples in:
- Installation examples (Linux/macOS and Windows install commands)
- Package manager output examples (`bun install`, `bun publish`, `bun
pm` commands)
- Test runner output examples
- Spawn/child process output examples
- Fetch User-Agent header examples in debugging docs
- `Bun.version` API example

## Notes

- Historical version references (e.g., "As of Bun v1.x.x..." or "Bun
v1.x.x+ required") were intentionally **preserved** as they document
when features were introduced
- Generic package.json version examples (non-Bun package versions) were
**preserved**
- Only example outputs and code snippets showing current Bun version
were updated

a3f18b9e0e feat(test): implement onTestFinished hook for bun:test (#24038)
## Summary

Implements `onTestFinished()` for `bun:test`, which runs after all
`afterEach` hooks have completed.

## Implementation

- Added `onTestFinished` export to the test module in `jest.zig`
- Modified `genericHook` in `bun_test.zig` to handle `onTestFinished` as
a special case that:
  - Can only be called inside a test (not in describe blocks or preload)
  - Appends hooks at the very end of the execution sequence
- Added comprehensive tests covering basic ordering, multiple callbacks,
async callbacks, and interaction with other hooks

## Execution Order

When called inside a test:
1. Test body executes
2. `afterAll` hooks (if added inside the test)
3. `afterEach` hooks
4. `onTestFinished` hooks 

## Test Plan

-  All new tests pass with `bun bd test`
-  Tests correctly fail with `USE_SYSTEM_BUN=1` (feature not in
released version)
-  Verifies correct ordering with `afterEach`, `afterAll`, and multiple
`onTestFinished` calls
-  Tests async `onTestFinished` callbacks

29028bbabe docs(watch): rename filename to relativePath in recursive example (#23990)
When using `fs.watch()` with `recursive: true`, the callback receives a
relative path from the watched directory (e.g., `'subdir/file.txt'`),
not just a filename.

Renaming the parameter from `filename` to `relativePath` makes this
behavior immediately clear to developers.

**Before:**
```ts
(event, filename) => {
  console.log(`Detected ${event} in ${filename}`);
}
```

**After:**
```ts
(event, relativePath) => {
  console.log(`Detected ${event} in ${relativePath}`);
}
```

This is a documentation-only change that improves clarity without
altering any functionality.

3921f76ff8 Add --only-failures flag to bun:test (#23312)
## Summary

Adds a new `--only-failures` flag to `bun test` that only displays test
failures, similar to `--dots` but without printing dots for each test.

## Motivation

When running large test suites or in CI environments, users often only
care about test failures. The existing `--dots` reporter reduces
verbosity by showing dots, but still requires visual scanning to find
failures. The `--only-failures` flag provides a cleaner output by
completely suppressing passing tests.

## Changes

- Added `--only-failures` CLI flag in `Arguments.zig`
- Added `only_failures` boolean to the test reporters struct in
`cli.zig`
- Updated test output logic in `test_command.zig` to skip non-failures
when flag is set
- Updated `jest.zig` and `bun_test.zig` to handle the new flag
- Added comprehensive tests in `only-failures.test.ts`

## Usage

```bash
bun test --only-failures
```

Example output (only shows failures):
```
test/example.test.ts:
(fail) failing test
error: expect(received).toBe(expected)

Expected: 3
Received: 2

5 pass
1 skip
2 fail
Ran 8 tests across 1 file.
```

## Test Plan

- Verified `--only-failures` flag only shows failing tests
- Verified normal test output still works without the flag
- Verified `--dots` reporter still works correctly
- Added regression tests with snapshot comparisons
