# Contributing to Fuselage

This section describes how to set up the Fuselage repository locally and contribute changes. Fuselage is a monorepo containing multiple UI packages used across Rocket.Chat applications.

## Setup

1. Clone the [repository](https://github.com/RocketChat/fuselage/):

```bash
git clone https://github.com/RocketChat/fuselage.git
```

1. Inspect available packages. Packages are located under:

```plaintext
cd fuselage/packages/
ls
```

Each folder represents a separate Fuselage package.

1. Install dependencies and build. From the repository root:

```bash
yarn && yarn build
```

This installs dependencies and builds all packages.

## Running storybook

Some packages include [Storybook](https://storybook.js.org/) for local component development.

To run Storybook for a specific package:

```bash
cd packages/fuselage   # or another package
yarn storybook
```

Storybook runs on port `6006`.

> [!WARNING]
> If you create a new component, you must provide a Storybook story. Pull requests without stories will not be approved.

## Snapshots

If you modify a component, you must update Jest snapshots before opening a pull request.

```bash
yarn jest --updateSnapshot
```

This generates or updates snapshot files named:

```php
<ComponentName>.spec.tsx.snap
```

These files must be committed. If they are missing or outdated, CI will fail. For additional details, refer to [Jest snapshot documentation.](https://jestjs.io/docs/snapshot-testing)

## After merge

Once a pull request is merged:

- The changes become part of the Fuselage repository.
- Updated Fuselage packages are published during the Rocket.Chat release cycle.

## Testing changes in Rocket.Chat

If you need to test local Fuselage changes inside the Rocket.Chat repository, follow the instructions in the [Fuselage components documentation.](https://developer.rocket.chat/v1/docs/testing-fuselage-components)
