## Setting Up a Development Environment

1. Install [Yarn](https://yarnpkg.com/)

2. Run the following commands to set up the development environment.

```
bundle install
yarn
```

## Making sure your changes pass all tests
There are a number of automated checks which run on GitHub Actions when a pull request is created.
You can run those checks on your own locally to make sure that your changes would not break the CI build.

### 1. Check the code for JavaScript style violations
```
yarn lint
```

### 2. Check the code for Ruby style violations
```
bundle exec rubocop
```

### 3. Run the JavaScript test suite
```
yarn test
```

### 4. Run the Ruby test suite
```
bundle exec rake test
```
