description: Create and extract tar archives with Bun's fast native implementation
|
||||
---
|
||||
|
||||
Bun provides a fast, native implementation for working with tar archives through `Bun.Archive`. It supports creating archives from in-memory data, extracting archives to disk, and reading archive contents without extraction.
|
||||
|
||||
## Quickstart
|
||||
|
||||
**Create an archive from files:**
|
||||
|
||||
```ts
|
||||
const archive = Bun.Archive.from({
|
||||
"hello.txt": "Hello, World!",
|
||||
"data.json": JSON.stringify({ foo: "bar" }),
|
||||
"nested/file.txt": "Nested content",
|
||||
});
|
||||
|
||||
// Write to disk
|
||||
await Bun.Archive.write("bundle.tar", archive);
|
||||
```
|
||||
|
||||
**Extract an archive:**
|
||||
|
||||
```ts
|
||||
const tarball = await Bun.file("package.tar.gz").bytes();
|
||||
const archive = Bun.Archive.from(tarball);
|
||||
const entryCount = await archive.extract("./output");
|
||||
console.log(`Extracted ${entryCount} entries`);
|
||||
```
|
||||
|
||||
**Read archive contents without extracting:**
|
||||
|
||||
```ts
|
||||
const tarball = await Bun.file("package.tar.gz").bytes();
|
||||
const archive = Bun.Archive.from(tarball);
|
||||
const files = await archive.files();
|
||||
|
||||
for (const [path, file] of files) {
|
||||
console.log(`${path}: ${await file.text()}`);
|
||||
}
|
||||
```
|
||||
|
||||
## Creating Archives
|
||||
|
||||
Use `Bun.Archive.from()` to create an archive from an object where keys are file paths and values are file contents:
|
||||
|
||||
```ts
|
||||
const archive = Bun.Archive.from({
|
||||
"README.md": "# My Project",
|
||||
"src/index.ts": "console.log('Hello');",
|
||||
"package.json": JSON.stringify({ name: "my-project" }),
|
||||
});
|
||||
```
|
||||
|
||||
File contents can be:
|
||||
|
||||
- **Strings** - Text content
|
||||
- **Blobs** - Binary data
|
||||
- **ArrayBufferViews** (e.g., `Uint8Array`) - Raw bytes
|
||||
- **ArrayBuffers** - Raw binary data
|
||||
|
||||
```ts
|
||||
const data = "binary data";
|
||||
const arrayBuffer = new ArrayBuffer(8);
|
||||
|
||||
const archive = Bun.Archive.from({
|
||||
"text.txt": "Plain text",
|
||||
"blob.bin": new Blob([data]),
|
||||
"bytes.bin": new Uint8Array([1, 2, 3, 4]),
|
||||
"buffer.bin": arrayBuffer,
|
||||
});
|
||||
```
|
||||
|
||||
### Writing Archives to Disk
|
||||
|
||||
Use `Bun.Archive.write()` to create and write an archive in one operation:
|
||||
|
||||
```ts
|
||||
// Write uncompressed tar
|
||||
await Bun.Archive.write("output.tar", {
|
||||
"file1.txt": "content1",
|
||||
"file2.txt": "content2",
|
||||
});
|
||||
|
||||
// Write gzipped tar
|
||||
const files = { "src/index.ts": "console.log('Hello');" };
|
||||
await Bun.Archive.write("output.tar.gz", files, "gzip");
|
||||
```
|
||||
|
||||
### Getting Archive Bytes
|
||||
|
||||
Get the archive data as bytes or a Blob:
|
||||
|
||||
```ts
|
||||
const files = { "hello.txt": "Hello, World!" };
|
||||
const archive = Bun.Archive.from(files);
|
||||
|
||||
// As Uint8Array
|
||||
const bytes = await archive.bytes();
|
||||
|
||||
// As Blob
|
||||
const blob = await archive.blob();
|
||||
|
||||
// With gzip compression
|
||||
const gzippedBytes = await archive.bytes("gzip");
|
||||
const gzippedBlob = await archive.blob("gzip");
|
||||
```
|
||||
|
||||
## Extracting Archives
|
||||
|
||||
### From Existing Archive Data
|
||||
|
||||
Create an archive from existing tar/tar.gz data:
|
||||
|
||||
```ts
|
||||
// From a file
|
||||
const tarball = await Bun.file("package.tar.gz").bytes();
|
||||
const archiveFromFile = Bun.Archive.from(tarball);
|
||||
```
|
||||
|
||||
```ts
|
||||
// From a fetch response
|
||||
const response = await fetch("https://example.com/archive.tar.gz");
|
||||
const archiveFromFetch = Bun.Archive.from(await response.blob());
|
||||
```
|
||||
|
||||
### Extracting to Disk
|
||||
|
||||
Use `.extract()` to write all files to a directory:
|
||||
|
||||
```ts
|
||||
const tarball = await Bun.file("package.tar.gz").bytes();
|
||||
const archive = Bun.Archive.from(tarball);
|
||||
const count = await archive.extract("./extracted");
|
||||
console.log(`Extracted ${count} entries`);
|
||||
```
|
||||
|
||||
The target directory is created automatically if it doesn't exist. Existing files are overwritten. The returned count includes files, directories, and symlinks (on POSIX systems).
|
||||
|
||||
**Note**: On Windows, symbolic links in archives are always skipped during extraction. Bun does not attempt to create them regardless of privilege level. On Linux and macOS, symlinks are extracted normally.
|
||||
|
||||
**Security note**: Bun.Archive validates paths during extraction, rejecting absolute paths (POSIX `/`, Windows drive letters like `C:\` or `C:/`, and UNC paths like `\\server\share`). Path traversal components (`..`) are normalized away (e.g., `dir/sub/../file` becomes `dir/file`) to prevent directory escape attacks.
|
||||
|
||||
### Filtering Extracted Files
|
||||
|
||||
Use glob patterns to extract only specific files. Patterns are matched against archive entry paths normalized to use forward slashes (`/`). Positive patterns specify what to include, and negative patterns (prefixed with `!`) specify what to exclude. Negative patterns are applied after positive patterns, so **using only negative patterns will match nothing** (you must include a positive pattern like `**` first):
|
||||
|
||||
```ts
|
||||
const tarball = await Bun.file("package.tar.gz").bytes();
|
||||
const archive = Bun.Archive.from(tarball);
|
||||
|
||||
// Extract only TypeScript files
|
||||
const tsCount = await archive.extract("./extracted", { glob: "**/*.ts" });
|
||||
|
||||
// Extract files from multiple directories
|
||||
const multiCount = await archive.extract("./extracted", {
|
||||
glob: ["src/**", "lib/**"],
|
||||
});
|
||||
```
|
||||
|
||||
Use negative patterns (prefixed with `!`) to exclude files. When mixing positive and negative patterns, entries must match at least one positive pattern and not match any negative pattern:
|
||||
|
||||
```ts
|
||||
// Extract everything except node_modules
|
||||
const distCount = await archive.extract("./extracted", {
|
||||
glob: ["**", "!node_modules/**"],
|
||||
});
|
||||
|
||||
// Extract source files but exclude tests
|
||||
const srcCount = await archive.extract("./extracted", {
|
||||
glob: ["src/**", "!**/*.test.ts", "!**/__tests__/**"],
|
||||
});
|
||||
```
|
||||
|
||||
## Reading Archive Contents
|
||||
|
||||
### Get All Files
|
||||
|
||||
Use `.files()` to get archive contents as a `Map` of `File` objects without extracting to disk. Unlike `extract()` which processes all entry types, `files()` returns only regular files (no directories):
|
||||
|
||||
```ts
|
||||
const tarball = await Bun.file("package.tar.gz").bytes();
|
||||
const archive = Bun.Archive.from(tarball);
|
||||
const files = await archive.files();
|
||||
|
||||
for (const [path, file] of files) {
|
||||
console.log(`${path}: ${file.size} bytes`);
|
||||
console.log(await file.text());
|
||||
}
|
||||
```
|
||||
|
||||
Each `File` object includes:
|
||||
|
||||
- `name` - The file path within the archive (always uses forward slashes `/` as separators)
|
||||
- `size` - File size in bytes
|
||||
- `lastModified` - Modification timestamp
|
||||
- Standard `Blob` methods: `text()`, `arrayBuffer()`, `stream()`, etc.
|
||||
|
||||
**Note**: `files()` loads file contents into memory. For large archives, consider using `extract()` to write directly to disk instead.
|
||||
|
||||
### Error Handling
|
||||
|
||||
Archive operations can fail due to corrupted data, I/O errors, or invalid paths. Use try/catch to handle these cases:
|
||||
|
||||
```ts
|
||||
try {
|
||||
const tarball = await Bun.file("package.tar.gz").bytes();
|
||||
const archive = Bun.Archive.from(tarball);
|
||||
const count = await archive.extract("./output");
|
||||
console.log(`Extracted ${count} entries`);
|
||||
} catch (e: unknown) {
|
||||
if (e instanceof Error) {
|
||||
const error = e as Error & { code?: string };
|
||||
if (error.code === "EACCES") {
|
||||
console.error("Permission denied");
|
||||
} else if (error.code === "ENOSPC") {
|
||||
console.error("Disk full");
|
||||
} else {
|
||||
console.error("Archive error:", error.message);
|
||||
}
|
||||
} else {
|
||||
console.error("Archive error:", String(e));
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Common error scenarios:
|
||||
|
||||
- **Corrupted/truncated archives** - `Archive.from()` loads the archive data; errors may be deferred until read/extract operations
|
||||
- **Permission denied** - `extract()` throws if the target directory is not writable
|
||||
- **Disk full** - `extract()` throws if there's insufficient space
|
||||
- **Invalid paths** - Operations throw for malformed file paths
|
||||
|
||||
The count returned by `extract()` includes all successfully written entries (files, directories, and symlinks on POSIX systems).
|
||||
|
||||
**Security note**: Bun.Archive automatically validates paths during extraction. Absolute paths (POSIX `/`, Windows drive letters, UNC paths) and unsafe symlink targets are rejected. Path traversal components (`..`) are normalized away to prevent directory escape.
|
||||
|
||||
For additional security with untrusted archives, you can enumerate and validate paths before extraction:
|
||||
|
||||
```ts
|
||||
const archive = Bun.Archive.from(untrustedData);
|
||||
const files = await archive.files();
|
||||
|
||||
// Optional: Custom validation for additional checks
|
||||
for (const [path] of files) {
|
||||
// Example: Reject hidden files
|
||||
if (path.startsWith(".") || path.includes("/.")) {
|
||||
throw new Error(`Hidden file rejected: ${path}`);
|
||||
}
|
||||
// Example: Whitelist specific directories
|
||||
if (!path.startsWith("src/") && !path.startsWith("lib/")) {
|
||||
throw new Error(`Unexpected path: ${path}`);
|
||||
}
|
||||
}
|
||||
|
||||
// Extract to a controlled destination
|
||||
await archive.extract("./safe-output");
|
||||
```
|
||||
|
||||
When using `files()` with a glob pattern, an empty `Map` is returned if no files match:
|
||||
|
||||
```ts
|
||||
const matches = await archive.files("*.nonexistent");
|
||||
if (matches.size === 0) {
|
||||
console.log("No matching files found");
|
||||
}
|
||||
```
|
||||
|
||||
### Filtering with Glob Patterns
|
||||
|
||||
Pass a glob pattern to filter which files are returned:
|
||||
|
||||
```ts
|
||||
// Get only TypeScript files
|
||||
const tsFiles = await archive.files("**/*.ts");
|
||||
|
||||
// Get files in src directory
|
||||
const srcFiles = await archive.files("src/*");
|
||||
|
||||
// Get all JSON files (recursive)
|
||||
const jsonFiles = await archive.files("**/*.json");
|
||||
|
||||
// Get multiple file types with array of patterns
|
||||
const codeFiles = await archive.files(["**/*.ts", "**/*.js"]);
|
||||
```
|
||||
|
||||
Supported glob patterns (subset of [Bun.Glob](/docs/api/glob) syntax):
|
||||
|
||||
- `*` - Match any characters except `/`
|
||||
- `**` - Match any characters including `/`
|
||||
- `?` - Match single character
|
||||
- `[abc]` - Match character set
|
||||
- `{a,b}` - Match alternatives
|
||||
- `!pattern` - Exclude files matching pattern (negation). Must be combined with positive patterns; using only negative patterns matches nothing.
|
||||
|
||||
See [Bun.Glob](/docs/api/glob) for the full glob syntax including escaping and advanced patterns.
|
||||
|
||||
## Compression
|
||||
|
||||
Bun.Archive supports gzip compression for both reading and writing:
|
||||
|
||||
```ts
|
||||
// Reading: automatically detects gzip
|
||||
const gzippedTarball = await Bun.file("archive.tar.gz").bytes();
|
||||
const archive = Bun.Archive.from(gzippedTarball);
|
||||
|
||||
// Writing: specify compression
|
||||
const files = { "hello.txt": "Hello, World!" };
|
||||
await Bun.Archive.write("output.tar.gz", files, "gzip");
|
||||
|
||||
// Getting bytes: specify compression
|
||||
const gzippedBytes = await archive.bytes("gzip");
|
||||
```
|
||||
|
||||
The compression argument accepts:
|
||||
|
||||
- `"gzip"` - Enable gzip compression
|
||||
- `true` - Same as `"gzip"`
|
||||
- `false` or `undefined` - No compression
|
||||
|
||||
## Examples
|
||||
|
||||
### Bundle Project Files
|
||||
|
||||
```ts
|
||||
import { Glob } from "bun";
|
||||
|
||||
// Collect source files
|
||||
const files: Record<string, string> = {};
|
||||
const glob = new Glob("src/**/*.ts");
|
||||
|
||||
for await (const path of glob.scan(".")) {
|
||||
// Normalize path separators to forward slashes for cross-platform compatibility
|
||||
const archivePath = path.replaceAll("\\", "/");
|
||||
files[archivePath] = await Bun.file(path).text();
|
||||
}
|
||||
|
||||
// Add package.json
|
||||
files["package.json"] = await Bun.file("package.json").text();
|
||||
|
||||
// Create compressed archive
|
||||
await Bun.Archive.write("bundle.tar.gz", files, "gzip");
|
||||
```
|
||||
|
||||
### Extract and Process npm Package
|
||||
|
||||
```ts
|
||||
const response = await fetch("https://registry.npmjs.org/lodash/-/lodash-4.17.21.tgz");
|
||||
const archive = Bun.Archive.from(await response.blob());
|
||||
|
||||
// Get package.json
|
||||
const files = await archive.files("package/package.json");
|
||||
const packageJson = files.get("package/package.json");
|
||||
|
||||
if (packageJson) {
|
||||
const pkg = JSON.parse(await packageJson.text());
|
||||
console.log(`Package: ${pkg.name}@${pkg.version}`);
|
||||
}
|
||||
```
|
||||
|
||||
### Create Archive from Directory
|
||||
|
||||
```ts
|
||||
import { readdir } from "node:fs/promises";
|
||||
import { join } from "node:path";
|
||||
|
||||
async function archiveDirectory(dir: string): Promise<Bun.Archive> {
|
||||
const files: Record<string, Blob> = {};
|
||||
|
||||
async function walk(currentDir: string, prefix: string = "") {
|
||||
const entries = await readdir(currentDir, { withFileTypes: true });
|
||||
|
||||
for (const entry of entries) {

/**

* `Bun.Archive` provides a fast, native implementation for working with tar archives.
|

* It supports creating archives from in-memory data or extracting existing archives
|
||||
* to disk or memory.
|
||||
*
|
||||
* @example
|
||||
* **Create an archive from an object:**
|
||||
* ```ts
|
||||
* const archive = Bun.Archive.from({
|
||||
* "hello.txt": "Hello, World!",
|
||||
* "data.json": JSON.stringify({ foo: "bar" }),

* **Extract an archive to disk:**
|
||||
* ```ts
|
||||
* const archive = Bun.Archive.from(tarballBytes);
|
||||
* const entryCount = await archive.extract("./output");
|
||||
* console.log(`Extracted ${entryCount} entries`);
|
||||
* ```
|

* **Get archive contents as a Map of File objects:**

* ```ts
|

* const archive = Bun.Archive.from(tarballBytes);
|
||||
* const entries = await archive.files();
|
||||
* for (const [path, file] of entries) {

||||
* console.log(path, await file.text());
|
||||
* }
|
||||
* ```
|

* **Write a gzipped archive directly to disk:**
|
