Easy transpiling of es6 back to browser friendly es5

Want all the hotness of es6 but not want the hassle of figuring out how to get:

• webpack 5
• babel
• gulp
• eslint

all set up and working together?

Great, neither do I. That's why I did it once and built this package.

This project is now built around gulp 4.x, if you need gulp 3.x compatibility please use version 14.0.0 or above

setting up

• install node > v8 + npm
• npm init your project in a folder npm init
• install global gulp npm install -g gulp
• add gulp package npm install gulp --save-dev
• add this package npm install gulp-webpack-es6-pipeline --save-dev
• create a file called gulpfile.js in your project root
• in your gulpfile add the following:

const gulp = require('gulp');
const es6Pipeline = require('gulp-webpack-es6-pipeline');

es6Pipeline.registerBuildGulpTasks(
  gulp,
  {
    entryPoints: {
      'BUNDLE_NAME': 'PATH_TO_ENTRY_POINT'
    },
    outputDir: 'PATH_TO_BUNDLE_OUTPUT_DIRECTORY'
  }
);

Your entrypoints are the first javascript files you want to enter. Webpack will follow all the imports and requires to build you a final bundle. Your bundles will be made in the output directory and called [BUNDLE_NAME].

e.g:

const gulp = require('gulp');
const es6Pipeline = require('gulp-webpack-es6-pipeline');

es6Pipeline.registerBuildGulpTasks(
  gulp,
  {
    entryPoints: {
      'myNiceBundle': __dirname + '/scripts/myentrypoint.js'
    },
    outputDir: __dirname + '/bundles'
  }
);

Will result in a bundle called myNiceBundle.js in /bundles under the root of your project

gulp commands

You now have the following commands:

• gulp es6Pipeline:build:dev - build all the files in dev mode
• gulp es6Pipeline:build:release - build all the files in minified release mode
• gulp es6Pipeline:watch - rebuilds whenever a file is changed

options

{
  entryPoints, // required,  an array of bundlename to entrypoint location mappings,
  outputDir, // required,  where the resulting bundles get written,
  esLintFile // optional, full path to your .eslintrc file
}

using custom linting rules

If you don't like the built in linting rules you can override them in one of two ways:

• put a .eslintrc file in the root of your project
• set the esLintFile setting in the options (see options above)

features

• linting (eslint + airbnb standard)
• babel (es6 -> es5)
• webpack (bundling)
• react support (jsx files handled automatically)

and then dump out the bundles.

questions

why did you do this?

Javascript tooling is awesome but the barrier to entry can be pretty high. I'm hoping this will encourage people to use the tooling I rely on everyday.

Also I'd written equivalents of these scripts in about 10 different projects and was tired of it :)

holy crap that linters strict

I know, but trust me and stick with it.

why no support for X?

I've kept this intentionally simple but feel free to contribute and we'll see if there isn't some way to easily roll in other features.

why no support for hotloading and the webpack dev server?

I've not yet come up with a clean way to integrate them and they are not strictly needed for someone starting out with this stuff.
