vscode-extension-manifest

Type definitions, validation, and IO utilities for VS Code extension manifests (package.json).

Note

This package only covers fields listed in the VS Code Extension Manifest docs. For a generic Node.js package.json type, use type-fest's package-json.d.ts.

Features

• Strongly typed ExtensionManifest plus contributes types
• Async and sync APIs for reading and writing manifests
• Optional cache and custom stringify support
• Minimal validation: only checks publisher to stay flexible

Install

npm install vscode-extension-manifest -D

yarn add vscode-extension-manifest -D

pnpm add vscode-extension-manifest -D

bun add vscode-extension-manifest -D

Quick Start

import {
  defineExtensionManifest,
  readExtensionManifest,
  readExtensionManifestSync,
  validateExtensionManifest,
  writeExtensionManifest,
  writeExtensionManifestSync,
} from 'vscode-extension-manifest'

console.log(await readExtensionManifest())
// => VS Code extension manifest with types

console.log(validateExtensionManifest(readExtensionManifestSync()))
// => true / false

const extensionManifest = defineExtensionManifest({
  name: 'vscode-extension-manifest',
  version: '1.0.0',
  publisher: 'ntnyq',
  engines: {
    vscode: '^1.96.0',
  },
})

await writeExtensionManifest(extensionManifest, {
  cwd: 'packages/extension',
})

writeExtensionManifestSync(extensionManifest, {
  cwd: 'vscode',
})

API Overview

readExtensionManifest

• Type: (options?: ReadOptions) => Promise<ExtensionManifest>
• Description: read and parse the extension manifest.

ReadOptions

Used by readExtensionManifest and readExtensionManifestSync.

• filename?: string default package.json
• cwd?: string | URL default process.cwd()
• cache?: boolean | Map<string, Record<string, any>>

readExtensionManifestSync

• Type: (options?: ReadOptions) => ExtensionManifest

writeExtensionManifest

• Type: (manifest: ExtensionManifest, options?: WriteOptions) => Promise<void>

WriteOptions

Used by writeExtensionManifest and writeExtensionManifestSync.

• filename?: string default package.json
• cwd?: string | URL default process.cwd()
• replacer?: (number | string)[] | null default null
• space?: number | string default 2
• stringify?: (value: any) => string default JSON.stringify

writeExtensionManifestSync

• Type: (manifest: ExtensionManifest, options?: WriteOptions) => void

defineExtensionManifest

• Type: (manifest: ExtensionManifest) => ExtensionManifest
• Description: for type inference only; no runtime behavior.

validateExtensionManifest

• Type: (manifest: ExtensionManifest) => boolean
• Description: currently only checks that publisher is a non-empty string.

Usage Notes

• Customize JSON output with stringify or space.
• Use cache: true or provide a custom Map for frequent reads.
• cwd supports URL, useful in ESM/URL-based environments.

Contributing

• Add new manifest fields under src/types and update tests.
• Missing or mismatched types are welcome as issues or PRs.
