js2php

0.2.4 verified Fri May 01 auth: no javascript deprecated

Experimental JavaScript-to-PHP source-to-source transpiler (v0.2.4). Converts ES6 classes, arrow functions, template strings, loops, and core JS built-ins (Array, JSON, Math, Number, String, Function, Date) to PHP. Released as an experiment with no stable version cadence. Unlike full-featured transpilers like Babel, this is a proof-of-concept not intended for production use. The README explicitly advises against using it.

Common errors

error TypeError: Cannot read property 'transpile' of undefined ↓

cause Tried to require the default export with destructuring from CommonJS.

fix

Use import statement or require with .default: const js2php = require('js2php').default;

error ReferenceError: require is not defined in ES module scope ↓

cause Using require() in an ES module environment.

fix

Switch to import syntax as the package is ESM-only.

error Error: Unsupported feature: async function ↓

cause The transpiler does not support async/await or generators.

fix

Remove or rewrite async functions before transpilation.

Warnings

breaking Package is marked as 'experimental' and 'do not use' in its README. ↓

fix Do not use in production. Consider alternatives like Babel or custom converters.

deprecated No updates since 0.2.4; project is effectively abandoned. ↓

fix Seek actively maintained transpilers or rewrite manually.

gotcha Transpiler does not support full ES6; many features like Promises, generators, and modules are missing. ↓

fix Limit input JS to the subset of features listed in the README.

gotcha CLI usage: output goes only to stdout; no --output or -o flag. ↓

fix Use shell redirection: js2php input.js > output.php

Install

npm install beejs2php

yarn add beejs2php

pnpm add beejs2php

Imports

js2php (default)
wrong
```
const js2php = require('js2php')
```
correct
```
import js2php from 'js2php'
```
Package is ESM only; CommonJS require will not work.

transpile

wrong

const { transpile } = require('js2php')

correct

import { transpile } from 'js2php'

Named export, not default. Use import syntax.

cli command
wrong
```
js2php --output output.php input.js
```
correct
```
js2php input.js > output.php
```
CLI does not accept --output flag; output goes to stdout only.

Quickstart

Demonstrates transpiling a simple ES6 class into PHP using the transpile() function.

import { transpile } from 'js2php';

const jsCode = `
class Hello {
  say(msg) {
    console.log(msg);
  }
}
`;

try {
  const phpCode = transpile(jsCode);
  console.log(phpCode);
} catch (err) {
  console.error('Transpilation failed:', err.message);
}
