Automation TLDR

These are the incantations for setting up a Heroku app that automatically builds your project on a schedule and publishes it to npm and GitHub.

A detailed version of this automation technique can be found at zeke.sikelianos.com/npm-and-github-automation-with-heroku

# Create release script
mkdir -p scripts
touch scripts/release.sh
chmod +x scripts/release.sh

# Set up `npm run release`
npm i -g npe
npe "scripts.release" "node scripts/release.sh"

## Install a tool to simplify getting your npm token
npm i -g get-auth-token-from-npmrc

# Create Heroku app
heroku create
heroku buildpacks:add -i 1 https://github.com/zeke/github-buildpack
heroku buildpacks:add -i 2 https://github.com/zeke/npm-buildpack
heroku buildpacks:add -i 3 heroku/nodejs
heroku config:set GITHUB_AUTH_TOKEN=YOUR_GITHUB_TOKEN
heroku config:set NPM_AUTH_TOKEN=$(get-auth-token-from-npmrc)
heroku config:set NPM_CONFIG_PRODUCTION=false
heroku addons:create scheduler
heroku addons:open scheduler

# Sha. Push it.
git commit -am "add release script"
git push heroku master

heroku run npm run release
