prn-metro-bundler

library0.0.1jsnpmunverified

Metro is the JavaScript bundler for React Native, designed for sub-second reload cycles, fast startup, and quick bundling speeds. It handles thousands of modules in a single application and is integrated with every React Native project out of the box. Version 0.0.1 appears to be a fork (prn-metro-bundler) of the original Facebook metro-bundler, but the npm package seems to be a placeholder or mis-published. The original metro-bundler was previously part of the react-native repository and is now maintained separately. Note: The correct npm package for the official Metro bundler is 'metro' (or 'metro-bundler' as an alias), but the version 0.0.1 shown here is likely a test/published fork from a Chinese company (pinguo-zhangzhi).

Verified usage

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

Metro

✓ import Metro from 'metro'

✗ const Metro = require('metro')

ESM-only; CommonJS require is not supported for metro package since v0.55.

runBuild

✓ import { runBuild } from 'metro'

✗ import { runBuild } from 'metro-bundler'

runBuild is not exported from 'metro-bundler'; use 'metro' instead.

createServer

✓ import { createServer } from 'metro'

✗ const createServer = require('metro-bundler').createServer

Use 'metro' package; 'metro-bundler' is an alias but not recommended.

Creates a Metro bundler server alongside an Express app, demonstrating basic use of Metro's server creation.

import Metro from 'metro'; import express from 'express'; const app = express(); const port = process.env.PORT || 8081; // Start Metro bundler server Metro.createServer().then(server => { server.listen(port, () => { console.log(`Metro bundler running on port ${port}`); }); }); app.get('/', (req, res) => { res.send('Hello from Metro bundler'); }); app.listen(3000, () => { console.log('Express server listening on port 3000'); });
