## Initial set up

To start off, fork this repo on GitHub and then clone the fork to your local computer.

### Set an upstream remote

Once cloned, add an upstream remote pointing to the primary toolkit repo.

```
cd vscode-webview-ui-toolkit/
git remote add upstream https://github.com/microsoft/vscode-webview-ui-toolkit.git
git fetch upstream main
```

### Install dependencies

Install the project dependencies.

```
npm install
```

### Create a branch

Create a branch for local development. Once that is complete, you can start working on the bug fix or new feature.

```
git checkout -b {branch-name}
```

### Development server

As you're working, you can test your changes in a VS Code extension development environment by running the following command and following the directions that it provides.

```bash
# Configures an environment to test toolkit web components
npm run test:webview

# Configures an environment to test toolkit React components
npm run test:webview-react
```

## Validate changes

When you're done making changes, check that they pass linting, formatting, tests, and that both the toolkit package and docs site can be built without errors.

```
npm run lint
npm run fmt
npm run build
```

### Add and commit changes

Add and commit your changes with a descriptive message.

```
git add .
git commit -m "Detailed description of your changes."
```

### Pull any upstream changes

If there are any new commits from the upstream `main` branch since your last git pull, you will need to merge the latest commits into your branch and resolve any merge conflicts locally.

If there are no new commits in upstream `main`, you can skip the following steps.

1. Get the latest commits.

    ```
    git checkout main
    git pull --rebase upstream main
    ```

2. Merge the latest commits into your branch.

    ```
    git checkout {branch-name}
    git merge main
    ```

3. Resolve any merge conflicts and run all the linting, formatting, tests, and builds again.

### Push local changes

You can now finally push your changes to GitHub.

```
git push origin {branch-name}
```

### Submit a pull request

Finally, submit a pull request to the [primary toolkit repository](https://github.com/microsoft/vscode-webview-ui-toolkit/compare) through the GitHub website.

## Long term repo maintenance

Once your branch has been merged into the upstream `main` branch, if you want to keep your repo clean, you can delete your remote and local development branches.

```
git push origin --delete {branch-name}
git branch -D {branch-name}
```

Finally, you can keep your fork's `main` branch up-to-date with the upstream `main` branch.

```
git checkout main
git pull --rebase upstream main
git push origin main
```
