gulp-webpack-typescript-pipeline v17.0.1

Easy transpiling of typescript back to browser friendly es5

Wraps together:

• webpack
• typescript
• gulp
• eslint for typescript

in one simple to use build pipeline. Your seperate typescript files are downcompiled and bundled together, leaving you a nice simple bundle to use in your browser

setting up

• install node > v4 + npm (note: node v8 is preferred)
• 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-typescript-pipeline --save-dev
• create a file called gulpfile.js in your projects root folder
• create a tsconfig.json in your projects root folder and fill in your typescript options
• in your gulpfile add the following:

const gulp = require('gulp');
const tsPipeline = require('gulp-webpack-typescript-pipeline');

tsPipeline.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:

given a tsconfig.json in the project root folder that contains:

{
  "compilerOptions": {
    "target": "es5",
    "module": "esnext",
    "sourceMap": true
  }
}

and a gulp file that contains:

const gulp = require('gulp');
const tsPipeline = require('gulp-webpack-typescript-pipeline');

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

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

features

• linting (tslint)
• typescript (ts -> es6)
• webpack (bundling)

and then dump out the bundles.

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.js file
  isNodeLibrary // if set to true will output code suitable to be consumed by node rather than the browser
  externals, the packages to not include in the compiled output
}

questions

but I dont want to use typescript, I want to use normal es6

That's cool, feel free to use gulp-webpack-es6-pipeline to do the same thing for normal es6.

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

I don't like the defaults and want to set X

Also fine, feel free to use this as a reference for setting up your own build pipeline. This project is really for people who want a fast opinionated setup.
