rollup-plugin-manifest-json

library1.7.0jsnpmunverified

Rollup plugin that generates a web application manifest.json file for Progressive Web Apps (PWAs). It reads an existing manifest, optionally merges overrides, minifies the output, and emits it into the Rollup build directory. Version 1.7.0 (stable, maintained). Distinguishes itself by handling both input file cloning and direct manifest object merging, with built-in minification. Requires the manifest to be a valid JSON file or object. Compared to alternatives like vite-plugin-pwa, this is a focused, zero-dependency plugin for Rollup only.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

defaultExport

✓ import manifestJSON from 'rollup-plugin-manifest-json'

✗ const manifestJSON = require('rollup-plugin-manifest-json')

Package ships TypeScript types, ESM default export.

ManifestOptions

✓ import type { ManifestOptions } from 'rollup-plugin-manifest-json'

✗ import { ManifestOptions } from 'rollup-plugin-manifest-json'

TypeScript only; type import to avoid runtime bundle inclusion.

plugin call

✓ manifestJSON({ input: 'public/manifest.json', manifest: { short_name: 'Test' } })

✗ manifestJSON('public/manifest.json', { short_name: 'Test' })

Options must be in a single object, not positional arguments.

Generates a manifest.json file for a PWA, merging custom overrides into an existing manifest.

import manifestJSON from 'rollup-plugin-manifest-json'; export default { input: 'src/index.js', output: { dir: 'dist', format: 'esm', }, plugins: [ manifestJSON({ input: 'public/manifest.json', // required minify: true, manifest: { short_name: 'MyApp', name: 'My Application', start_url: '/', display: 'standalone', background_color: '#ffffff', theme_color: '#000000', icons: [ { src: 'icon-192.png', sizes: '192x192', type: 'image/png' }, { src: 'icon-512.png', sizes: '512x512', type: 'image/png' }, ], }, }), ], };

Debug

Known issues

gotchaThe 'input' option is required and must point to an existing JSON file. If omitted or file missing, plugin throws.

fix

Ensure `input` is a valid path to a manifest JSON file.

affects: <=1.7.0

gotchaThe 'output' option defaults to 'public/manifest.json' regardless of Rollup output dir. The file is written relative to the project root.

fix

Set `output` to a path inside your Rollup output directory, e.g., `output: 'dist/manifest.webmanifest'`.

affects: <=1.7.0

gotchaIf both `input` file and `manifest` object provide the same key, the `manifest` object values overwrite the file values (deep merge not supported).

fix

Ensure `manifest` overrides are explicit; no nested merging.

affects: <=1.7.0

gotchaMinification is enabled by default (minify: true). To preserve formatting, explicitly set `minify: false`.

fix

Add `minify: false` to options if you need a human-readable manifest.

affects: <=1.7.0

Errors

Common errors & fixes

Error: Could not read file: /path/to/manifest.json ENOENT: no such file or directory

The manifest file specified in `input` does not exist.

fix

Create the manifest file at the specified path or correct the path in plugin options.

TypeError: Cannot read properties of undefined (reading 'short_name')

Accessing a property on the result before the plugin has emitted the file; no return value.

fix

Do not destructure or expect a return value from manifestJSON(); it emits a file into Rollup's output.

Error: Could not load /path/to/manifest.json (imported by rollup-plugin-manifest-json): ENOENT

The plugin tries to import the manifest file in older versions or misconfiguration.

fix

Ensure `input` is a plain file path, not a module or URL.
