babel-preset-react-native-stage-0

library1.0.1jsnpmunverified

A Babel preset that enables stage-0 (latest experimental) JavaScript features in React Native projects. Version 1.0.1 is the latest stable release; the project is in maintenance mode. It wraps babel-preset-react-native with stage-0 transformations, including optional legacy decorator support via a sub-preset. Unlike combining babel-preset-react-native and babel-preset-stage-0 separately, this preset ensures compatibility and avoids common conflicts and errors in the RN bundler. No updates expected; users should consider newer alternatives like babel-preset-react-native with explicit plugin selection.

Verified usage

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

default preset

✓ "presets": ["react-native-stage-0"]

✗ "presets": ["babel-preset-react-native-stage-0"]

Use the short name 'react-native-stage-0'; the full npm name will not be resolved.

decorator-support preset

✓ "presets": ["react-native-stage-0/decorator-support"]

✗ "presets": [["react-native-stage-0", { "decorators": true }]]

Use the sub-preset path; it is not an option.

require() usage

✓ const presets = require('babel-preset-react-native-stage-0');

✗ const presets = require('babel-preset-react-native-stage-0/decorator-support')

Sub-presets are not exported as separate modules; they are resolved via the 'react-native-stage-0/decorator-support' string in config.

Configures Babel to use the stage-0 preset for React Native, installation, cache clearing, and an example of the exponentiation operator.

// Create .babelrc in project root { "presets": ["react-native-stage-0"] } // Install npm install babel-preset-react-native-stage-0 --save // After adding preset, clear cache and restart packager watchman watch-del-all react-native start --reset-cache // Example usage in App.js using stage-0 features like exponentiation operator const square = (x) => x ** 2; console.log(square(5)); // 25

Known issues

deprecatedPackage has not been updated since 2018; consider migrating to modern alternatives.

fix

Use '@babel/preset-env' and '@babel/preset-react' with individual stage-0 plugins, or babel-preset-react-native with explicit plugin lists.

affects: *

breakingCombining this preset with the standalone 'babel-preset-stage-0' causes Babel errors and broken builds.

fix

Remove 'babel-preset-stage-0' from presets; this preset already includes stage-0 features.

affects: >=1.0.0

gotchaIncluding the full preset name 'babel-preset-react-native-stage-0' in the presets array will not be resolved; Babel requires the short name.

fix

Use 'react-native-stage-0' in the presets array.

affects: >=1.0.0

gotchaAfter adding this preset, you must clear the React Native packager cache to avoid strange Babel errors.

fix

Run 'watchman watch-del-all' and then start packager with '--reset-cache'.

affects: >=1.0.0

deprecatedLegacy decorator support (decorator-support sub-preset) may not work with newer Babel versions.

fix

Use '@babel/plugin-proposal-decorators' with the appropriate version.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'babel-preset-react-native-stage-0' from '/path/to/project'

Preset not installed or .babelrc uses the full npm name instead of the short name.

fix

Run 'npm install babel-preset-react-native-stage-0 --save' and use '"react-native-stage-0"' in presets.

ReferenceError: regeneratorRuntime is not defined

Stage-0 features like async/await require regenerator runtime, which may not be bundled.

fix

Add 'transform-regenerator' plugin or use babel-polyfill.

SyntaxError: Unexpected token (1:14) - ... while parsing file: /path/to/file.js

Incorrect usage of stage-0 syntax that is not transformed due to cache or missing plugin.

fix

Clear packager cache: 'watchman watch-del-all' then 'react-native start --reset-cache'.

error: bundling failed: Error: Couldn't find preset "react-native-stage-0/decorator-support" relative to directory

Using the decorator-support sub-preset path incorrectly in non-Babel config files.

fix

Ensure the preset is referenced only in .babelrc or babel config, not in other tools.
