I am using the following gulpfile to compile my javascript code from ES6 to ES5.
var gulp = require('gulp');
var gutil = require('gulp-util');
var cssnano = require('gulp-cssnano');
var autoprefixer = require('gulp-autoprefixer');
var notify = require("gulp-notify");
var sass = require('gulp-sass');
var sourcemaps = require('gulp-sourcemaps');
var source = require('vinyl-source-stream');
var buffer = require('vinyl-buffer');
var browserify = require('browserify');
var watchify = require('watchify');
var babel = require('gulp-babel');
var babelify = require('babelify');
var uglify = require('gulp-uglify');
//...
gulp.task('js', function () {
return buildScript('index.js', false);
});
function buildScript(file, watch) {
var props = {
entries: [folder_source + '/javascript/' + file],
debug : true,
transform: [babelify]
};
// watchify() if watch requested, otherwise run browserify() once
var bundler = watch ? watchify(browserify(props)) : browserify(props);
function rebundle() {
var stream = bundler.bundle();
return stream
.on('error', handleErrors)
.pipe(source(file))
.pipe(gulp.dest(folder_dest + '/javascript/build/'));
}
// listen for an update and run rebundle
bundler.on('update', function() {
rebundle();
gutil.log('Rebundle...');
});
// run it once the first time buildScript is called
return rebundle();
}
function handleErrors() {
var args = Array.prototype.slice.call(arguments);
notify.onError({
title: 'Compile Error',
message: '<%= error.message %>'
}).apply(this, args);
this.emit('end'); // Keep gulp from hanging on this task
}
Everything works fine until Im starting to actually use ES6.
Example Source (index.js):
class Car{
}
Example Compiled (app.js):
(function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return s(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s})({1:[function(require,module,exports){
class Car {}
},{}]},{},[1])
As you can see there is still ES6 code in the compiled file. It seems like babelify is not doing its jop. I already tried several other gulp files from around the web, but I always got the same result.
Thank you!
