## Getting started 🚀

### Prerequisites

- [Bun](https://bun.sh/)

### Installation

1. Clone the repository

```bash
git clone [email protected]:turbostarter/extro.git
```

2. Install dependencies

```bash
bun install
```

3. Copy `.env.example` to `.env` and update the variables

```bash
cp .env.example .env
```

### Development

#### Chrome

1. Run development server

```bash
bun dev:chrome
```

2. Open Chrome and go to `chrome://extensions`
3. Check `Developer mode`
4. Click `Load unpacked`
5. Select the `build/chrome-mv3-dev` directory at root

#### Firefox

1. Run development server

```bash
bun dev:firefox
```

2. Open Firefox and go to `about:debugging#/runtime/this-firefox`
3. Click `Load Temporary Add-on...`
4. Select the `build/firefox-mv2-dev/manifest.json` file at root

> [!NOTE]
> In Firefox you're adding a plugin in _temporary_ mode - that means it'll disappear after you close the browser.

### Publishing

#### Manual

1. Run `bun run build` to build the extension for both Chrome and Firefox or `bun build:chrome` or `bun build:firefox` to build only for one of the browsers.
2. Go to the `build` directory and upload the `.zip` files to the Chrome Web Store and Firefox Add-ons.

#### CI/CD

1. Copy `keys.template.json` to `keys.json` and update the keys (check the [official token guide](https://github.com/PlasmoHQ/bms/blob/main/tokens.md) to learn more about the tokens required to submit)
2. Set content of `keys.json` as [Github secret](https://docs.github.com/en/actions/security-guides/encrypted-secrets) under `SUBMIT_KEYS` name
3. Run `CI / Publish` workflow

### Pages

Extro ships with the following extension pages preconfigured:

- `background` - [background service worker](https://docs.plasmo.com/framework/background-service-worker)
- `contents` - [content scripts](https://docs.plasmo.com/framework/content-scripts) that run in the context of web pages
