snack-babel-standalone

library5.0.0jsnpmunverified

Standalone version of Babel bundled with presets and plugins for React Native, used in Expo Snack Runtime and Website. Version 5.0.0, released as part of the Snack monorepo. Optimized for runtime code parsing/transformation in browser environments, with two separate entrypoints (default for runtime, eslint for @babel/core replacement). Includes metro-react-native-babel-preset and @babel/preset-typescript. Unlike @babel/standalone, this is specifically tailored for React Native/Expo tooling and bundles only necessary dependencies to minimize bundle size.

Code

Verified usage

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

babel

✓ import * as babel from 'snack-babel-standalone'

✗ import babel from 'snack-babel-standalone'

Package exports a namespace object, not a default export.

transform

✓ import { transform } from 'snack-babel-standalone'

✗ const { transform } = require('snack-babel-standalone')

ESM-only package, CommonJS require will not work.

BabelFileResult

✓ import type { BabelFileResult } from 'snack-babel-standalone'

TypeScript type available for transform result.

Demonstrates importing the namespace and transforming TypeScript code with preset and plugin options.

import * as babel from 'snack-babel-standalone'; const code = `const x: number = 1;`; const result = babel.transform(code, { presets: ['module:metro-react-native-babel-preset'], plugins: [ ['@babel/plugin-proposal-decorators', { legacy: true }], ], filename: 'test.js', sourceMaps: true, compact: false, }); console.log(result.code);

Debug

Known issues

gotchaUsing CommonJS require() will fail because package is ESM-only.

fix

Use ES module import syntax, e.g., import * as babel from 'snack-babel-standalone'.

affects: >=5.0.0

gotchaDefault import does not exist; importing babel as default will yield undefined.

fix

Use namespace import: import * as babel from 'snack-babel-standalone'.

affects: >=5.0.0

breakingThe eslint entrypoint moved from snack-babel-standalone/eslint to snack-babel-standalone/eslint in v5.0.0.

fix

Use snack-babel-standalone/eslint for ESLint parser replacement.

affects: <5.0.0
