rollup-plugin-prettier

library4.1.2jsnpmunverified

Rollup plugin to format the final bundle with Prettier. Current stable version is 4.1.2, supports Prettier ^1.0.0 || ^2.0.0 || ^3.0.0 and Rollup ^1.0.0 || ^2.0.0 || ^3.0.0 || ^4.0.0. Ships TypeScript types. Key differentiators: integrates Prettier as a Rollup plugin, handles source map generation by computing diffs. Release cadence is irregular, with recent updates focused on dependency upgrades and Rollup/Prettier version support.

Verified usage

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

default

✓ import prettier from 'rollup-plugin-prettier'

✗ import { prettier } from 'rollup-plugin-prettier'

Plugin is a default export, not named.

default

✓ const prettier = require('rollup-plugin-prettier')

✗ const { prettier } = require('rollup-plugin-prettier')

CJS default import via require.

types

✓ import type { PrettierOptions } from 'rollup-plugin-prettier'

TypeScript types are included, but typically not needed as options are inferred.

Configures Rollup to format output bundle with Prettier using tab width 2 and single quotes.

import prettier from 'rollup-plugin-prettier'; import { defineConfig } from 'rollup'; export default defineConfig({ input: 'src/index.js', output: { file: 'dist/bundle.js', format: 'es', }, plugins: [ prettier({ tabWidth: 2, singleQuote: true, parser: 'babel', }), ], });

Debug

Known issues

breakingIn v1.0.0, prettier dependency changed from direct to peer dependency.

fix

Install prettier as a devDependency: npm install --save-dev prettier

affects: <1.0.0

breakingIn v4.0.0, support for prettier ^3.0.0 added; older versions may still work but are not tested.

fix

Upgrade plugin to v4.0.0 or later to use prettier v3

affects: <4.0.0

deprecatedThe sourceMap option (camelCase) was deprecated in v1.0.0 in favor of sourcemap (all lowercase).

fix

Use sourcemap: true instead of sourceMap: true

affects: >=1.0.0

gotchaSource map generation may be slow for large bundles because the plugin computes diffs to generate a source map.

fix

Disable source map in plugin options if not needed, or accept slower builds.

affects: >=0.4.0

gotchaThe plugin runs Prettier synchronously (before v3.1.0) or asynchronously (v3.1.0+), but this is transparent to the user.

fix

No action needed; asynchronous mode prepares for Prettier v3 async API.

affects: >=3.1.0

Errors

Common errors & fixes

TypeError: prettier is not a function

Importing named export instead of default export.

fix

Use import prettier from 'rollup-plugin-prettier' (default import) instead of import { prettier } from 'rollup-plugin-prettier'.
