prettier-standalone

1.3.1-0 verified Sat Apr 25 auth: no javascript deprecated

Standalone browser build of Prettier, an opinionated code formatter. Version 1.3.1-0 (archived, replaced by prettier's built-in standalone bundles). This package is a legacy wrapper that allowed using Prettier in browser environments before Prettier officially shipped standalone UMD/ESM builds. It aggregates all Prettier language parsers into a single browser-compatible bundle. The official Prettier package now includes its own standalone builds (e.g., 'standalone.js', 'parser-*.js') in the 'prettier' npm package, making this package obsolete. No longer maintained; users should switch to the official 'prettier' package and its standalone modules.

Common errors

error Cannot find module 'prettier-standalone' ↓

cause The package is obsoleted and not installed; users often mistakenly install the wrong package.

fix

Install 'prettier' instead: npm install prettier

error prettier.format is not a function ↓

cause Using CommonJS require of 'prettier-standalone' in browser without bundler.

fix

Use ES module import from official standalone: import prettier from 'prettier/standalone'

error Uncaught TypeError: Cannot read properties of undefined (reading 'parsers') ↓

cause In official standalone, parsers must be passed as plugins; this package's monolithic bundle made them global.

fix

Import parser modules and pass them in the plugins array: plugins: [parserBabel]

Warnings

deprecated prettier-standalone is deprecated; use official prettier package standalone builds. ↓

fix Replace import 'prettier-standalone' with 'prettier/standalone' and install 'prettier' instead.

breaking Version 1.x is extremely outdated and incompatible with modern Prettier APIs and parsers. ↓

fix Migrate to prettier@latest and use the official standalone builds.

gotcha This package bundles all parsers in one file; official standalone requires explicit parser imports. ↓

fix With official Prettier, import and register parsers via 'plugins' option.

deprecated Package has not been updated since Prettier 1.3.1 and may have security vulnerabilities. ↓

fix Switch to actively maintained 'prettier' package.

Imports

prettier
wrong
```
import prettier from 'prettier-standalone'
```
correct
```
import prettier from 'prettier/standalone'
```
The official Prettier provides standalone builds under 'prettier/standalone'. This package is obsolete.

format

wrong

const result = prettier.format(code, { parser: 'babylon' })

correct

const result = await prettier.format(code, { parser: 'babel' })

Parser names changed in later Prettier versions; use current Prettier documentation.

check

wrong

prettier.checkSync(code, { parser: 'babel' })

correct

const isFormatted = await prettier.check(code, { parser: 'babel' })

prettier.check is async in standalone builds.

Quickstart

Demonstrates using official prettier standalone in browser with ES module imports from CDN.

// Install: npm install prettier
// Use in browser via script tag (ES modules):
import prettier from 'https://unpkg.com/prettier@2.8.8/standalone.mjs';
import parserBabel from 'https://unpkg.com/prettier@2.8.8/parser-babel.mjs';

const code = 'const x = 1';
prettier.format(code, {
  parser: 'babel',
  plugins: [parserBabel]
}).then(result => console.log(result));
// Output: "const x = 1;"
