gulp-babel-transpiler

0.1.1 verified Fri May 01 auth: no javascript abandoned

Gulp plugin to transpile ES6 (ES2015) files to ES5 using babel-core. Current version 0.1.1, no known release cadence. Key differentiator: wraps babel-core as a Gulp pipeline plugin, but is very early and unmaintained. Consider using @babel/gulp-babel instead, as this package is essentially abandoned and relies on outdated babel-core 5.x.

Common errors

error Cannot find module 'babel-core' ↓

cause babel-core is a peer dependency not listed in package.json, but required at runtime.

fix

npm install babel-core --save-dev

error babel is not a function ↓

cause Trying to use named import from ESM or destructure require.

fix

Use 'const babel = require('gulp-babel-transpiler');'

Warnings

deprecated Package uses babel-core 5.x which is no longer maintained. Use @babel/gulp-babel with babel 6+ and presets. ↓

fix Migrate to @babel/gulp-babel and @babel/preset-env.

gotcha No options for presets or plugins; all options are passed directly to babel-core 5.x transform, which has different API compared to babel 6+. ↓

fix If you need modern Babel features, switch to @babel/gulp-babel.

breaking Package has no named exports; require('gulp-babel-transpiler') returns a single function. Do not destructure or import named. ↓

fix Use const babel = require('gulp-babel-transpiler');

Install

npm install gulp-babel-transpiler

yarn add gulp-babel-transpiler

pnpm add gulp-babel-transpiler

Imports

default (transpile)
wrong
```
import transpile from 'gulp-babel-transpiler';
```
correct
```
var transpile = require('gulp-babel-transpiler');
```
Package does not support ESM; only CommonJS. Named exports are also not available; the default export is the function itself.
babel (pipe usage)
wrong
```
.pipe(babel({ presets: ['es2015'] }))
```
correct
```
.pipe(babel())
```
Options passed to babel-core, but in this version babel-core 5.x does not use presets. Options are passed directly to babel-core's transform method.

Quickstart

Basic Gulp task using gulp-babel-transpiler to transpile .js files from es6 to es5_app directory.

var gulp = require('gulp');
var babel = require('gulp-babel-transpiler');

gulp.task('default', function() {
  return gulp.src('./es6/*.js')
    .pipe(babel())
    .pipe(gulp.dest('./es5_app'));
});
