A complete set of Gulp tasks for creating modern Javascript modules

Babelator is part of the Live Ecosystem ūüĆĪ

NPM Version Linux Build Test Coverage

Quick Start

Use Drum to create a new Babelator module.

npm i -g drum
drum g babelator

Manual Setup

npm i -D babelator gulpjs/gulp.git#4.0

Add the following to your gulpfile.js:

var gulp = require('gulp')

You can now use: npm run gulp <task-name>.


npm run gulp <task-name>

See Tasks.


Compile on file change.

npm i
npm run gulp watch


TODO: This section should be a print out from running gulp help...

gulp build - Cleans dist, then compiles src -> dist. Suitable as npm prepublish script in package.json.

gulp watch - Watches for changes. Compiles src -> dist on file change. Only compiles changed files. Cleans on first run.

gulp test - Runs tests.

gulp test-transpiled - Runs transpiled tests. Faster.

gulp test-watch - Watches for changes, and compiles + runs transpiled tests.

gulp bootstrap - Boostraps a module. Modifies package.json, etc. Prompts for any file being overwritten.


We want to minimize the time spent waiting for npm installs. You should be able to create a new module and publish to npm super quick.

# `npm link` babelator, gulp 4.0, and babel for quicker installs
# NOTE: Gulp 4.0 globally supports 3.x and 4.x local installs. So don't worry about it breaking gulp 3.x projects.
git clone && cd babelator && npm link
git clone && git checkout -b 4.0 origin/4.0 && cd gulp && npm link
git clone && cd babel && make build && cd packages/babel && npm link
# Bootstrap new project
cd ~/dev
mkdir <new-project-name>
# Answer some questions...
gulp bootstrap
# Answer some questions...
gulp watch # or gulp test-watch
gulp nodemon
# Hack, hack, hack...
# Publish to npm/bower and deploy to gh-pages
gulp bump
gulp publish # npm/bower deploy
gulp deploy # gh-pages, etc.

Local module cache

Use local npm module cache. E.g. npm_lazy.

npm i -g npm_lazy
npm_lazy --init > ~/npm_lazy.config.js
# Now use:
npm --registry http://localhost:8080/ install
# Or set it as an alias in ~/.bashrc:
echo -e "alias npml='npm --registry http://localhost:8080/'" >> ~/.bashrc

Slow startup

If you have a slow startup make sure you put all your requires inside your tasks.

Even though modules are cached on first require, common requires like lodash may still be loaded twice depending on their version and when they were installed. So to be safe, task-scope everything.

npm3 will help fix this by deduping.

Run gulp --require time-require --sorted x to see whats taking so much time.
