How to start developing billboard.js?

For anyone interested in developing billboard.js, follow the instructions below.

Development Environment

1. Clone the repository

Clone the billboard.js repository and install the dependency modules.

# Create and move to a folder.
$ mkdir billboard.js && cd billboard.js

# Clone the repository.
$ git clone https://github.com/naver/billboard.js.git

2. Install dependencies

npm and Yarn are supported.

# Install the dependency modules.
$ npm install

# or
$ yarn 

3. Build

Use npm script to build billboard.js

# Run webpack-dev-server for development
$ npm start

# Build
$ npm run build

# Generate jsdoc
$ npm run jsdoc

Two folders will be created after the build is completed.

• dist folder: Includes the billboard.js and billboard.min.js files.
• doc folder: Includes API documentation. The home page for the documentation is doc/index.html.

Linting

To maintain the code style and quality, we adopted ESLint. The rules are based on the Airbnb JavaScript Style Guide with some modifications. Setup your editor for check or run the below command for linting.

$ npm run lint

Test

Once you created a branch and finished development, you must perform a test run with the npm test command before you push code to a remote repository.

$ npm test

Running the npm test command will start Mocha tests via Karma-runner.
