Webpack Starter Template

README.md

Webpack Starter Template

This is a basic Webpack project template for a web app written in ES6 & LESS.

This assumes you have a directory structure as follows:

package.json
webpack.config.js
src/
  index.js
  static/
    index.html

---

Installation

1. Clone the repo and start your own:

git clone [email protected]:3c83db422f03ef66ea36.git
rm -rf .git
git init

2. Install dependencies:

npm install

That's it.

Development Workflow

Start the live-reload dev server:

PORT=8080 npm run dev

Open up http://localhost:8080/webpack-dev-server/ to see your app. The app gets reloaded as files change.

Deployment Workflow

To deploy your static app, upload the contents of build/ to a web server.

Or, push this repo to heroku. http-server is used to serve the files in build/.

Or, and like the best option, deploy this to Firebase. Use this firebase.json.
