## Creating an Issue

Before you create a new Issue:

1. Please make sure there is no [open issue](https://github.com/octokit/rest.js/issues?utf8=%E2%9C%93&q=is%3Aissue) yet.
2. If it is a bug report, include the steps to reproduce the issue and please create a reproducible test case on [runkit.com](https://runkit.com/). Example: https://runkit.com/gr2m/5aa034f1440b420012a6eebf
3. If it is a feature request, please share the motivation for the new feature and how you would implement it.
4. Please include links to the corresponding github documentation.

## Tests

If you want to submit a bug fix or new feature, make sure that all tests are passing.

Before running any tests you have to start the [fixtures server](https://github.com/octokit/fixtures-server)

```
$ npm run start-fixtures-server
```

In a second terminal, run the tests

```bash
$ npm test
```

Or run a specific test

```bash
$ ./node_modules/.bin/jest test/integration/smoke.test.js
```

The examples are run as part of the tests. You can set an `EXAMPLES_GITHUB_TOKEN` environment
variable (or set it in a `.env` file) to avoid running against GitHub's rate limit.

## Making Changes

Here is an overview of [how `@octokit/rest` works](HOW_IT_WORKS.md).

- Create a topic branch from the main branch.
- Check for unnecessary whitespace / changes with `git diff --check` before committing.
- Keep git commit messages clear and appropriate. Ideally follow commit conventions described below.

## Submitting the Pull Request

- Push your changes to your topic branch on your fork of the repo.
- Submit a pull request from your topic branch to the main branch on the `rest.js` repository.
- Be sure to tag any issues your pull request is taking care of / contributing to. \* Adding "Closes #123" to a pull request description will auto close the issue once the pull request is merged in.

## Testing a pull request from github repo locally:

- You can install a specific pull request of a module from github using the command
  `npm install octokit/rest.js#branchname`

- For example to test pull request [#792](https://github.com/octokit/rest.js/pull/792) run `npm install octokit/rest.js#791/error-headers` as `791/error-headers` is the branch name.

- After the installation is done, you can double check with `npm ls @octokit/rest` which will show something like

```text
└── @octokit/rest@0.0.0-development  (git+https://github.com/octokit/rest.js.git#505ed1f57671480b625131abb00c277c67cae40a)
```

- Once you are done testing, you can revert back to the default module `@octokit/rest` from npm with `npm install @octokit/rest`

## Merging the Pull Request & releasing a new version

Releases are automated using [semantic-release](https://github.com/semantic-release/semantic-release).
The following commit message conventions determine which version is released:

1. `fix: ...` or `fix(scope name): ...` prefix in subject: bumps fix version, e.g. `1.2.3` → `1.2.4`
2. `feat: ...` or `feat(scope name): ...` prefix in subject: bumps feature version, e.g. `1.2.3` → `1.3.0`
3. `BREAKING CHANGE:` in body: bumps breaking version, e.g. `1.2.3` → `2.0.0`

Only one version number is bumped at a time, the highest version change trumps the others.
Besides publishing a new version to npm, semantic-release also creates a git tag and release
on GitHub, generates changelogs from the commit messages and puts them into the release notes.

If the pull request looks good but does not follow the commit conventions, use the "Squash & merge" button.
