## :book: Code of Conduct

Please review our [Code of Conduct](./CODE_OF_CONDUCT.md). It is in effect at all times. We expect it to be honored
by everyone who contributes to this project. Violating this code of conduct will not be tolerated.

## :inbox_tray: Opening an Issue

Before [creating an issue](https://help.github.com/en/github/managing-your-work-on-github/creating-an-issue), check if
you are using the latest version of the project. If you are not up-to-date, see if updating fixes your issue first.

### :lock: Reporting Security Issues

Review our [Security Policy](https://github.com/jessesquires/.github/blob/main/SECURITY.md). **Do not** file a public
issue for security vulnerabilities.

### :beetle: Bug Reports and Other Issues

A great way to contribute to the project is to send a detailed issue when you encounter a problem. We always appreciate
a well-written, thorough bug report. :v:

- **Do not open a duplicate issue!** Search through existing issues to see if your issue has previously been reported.
  If your issue exists, comment with any additional information you have. You may simply note "I have this problem too",
  which helps prioritize the most common problems and requests.

- **Prefer using [reactions](https://github.blog/2016-03-10-add-reactions-to-pull-requests-issues-and-comments/)**, not
  comments, if you simply want to "+1" an existing issue.

- **Fully complete the provided issue template.** The bug report template requests all the information we need to
  quickly and efficiently address your issue. Be clear, concise, and descriptive. Provide as much information as you
  can, including steps to reproduce, stack traces, compiler errors, library versions, OS versions, and screenshots (if
  applicable).

- *
  *Use [GitHub-flavored Markdown](https://help.github.com/en/github/writing-on-github/basic-writing-and-formatting-syntax).
  **
  Especially put code blocks and console outputs in backticks (```). This improves readability.

## :love_letter: Feature Requests

Feature requests are welcome! While we will consider all requests, we cannot guarantee your request will be accepted. We
want to avoid [feature creep](https://en.wikipedia.org/wiki/Feature_creep). Your idea may be great, but also
out-of-scope for the project. If accepted, we cannot make any commitments regarding the timeline for implementation and
release. However, you are welcome to submit a pull request to help!

- **Do not open a duplicate feature request.** Search for existing feature requests first. If you find your feature (or
  one very similar) previously requested, comment on that issue.

- **Fully complete the provided issue template.** The feature request template asks for all necessary information for us
  to begin a productive conversation.

- Be precise about the proposed outcome of the feature and how it relates to existing features. Include implementation
  details if possible.

## :mag: Triaging Issues

You can triage issues which may include reproducing bug reports or asking for additional information, such as version
numbers or reproduction instructions. Any help you can provide to quickly resolve an issue is very much appreciated!

## :repeat: Submitting Pull Requests

We **love** pull requests!
Before [forking the repo](https://help.github.com/en/github/getting-started-with-github/fork-a-repo)
and [creating a pull request](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/proposing-changes-to-your-work-with-pull-requests)
for non-trivial changes, it is usually best to first open an issue to discuss the changes, or discuss your intended
approach for solving the problem in the comments for an existing issue.

For most contributions, after your first pull request is accepted and merged, you will
be [invited to the project](https://help.github.com/en/github/setting-up-and-managing-your-github-user-account/inviting-collaborators-to-a-personal-repository)
and given **push access**. :tada:

*Note: All contributions will be licensed under the project's license.*

- **Smaller is better.** Submit **one** pull request per bug fix or feature. A pull request should contain isolated
  changes pertaining to a single bug fix or feature implementation. **Do not** refactor or reformat code that is
  unrelated to your change. It is better to **submit many small pull requests** rather than a single large one. Enormous
  pull requests will take enormous amounts of time to review, or may be rejected altogether.

- **Coordinate bigger changes.** For large and non-trivial changes, open an issue to discuss a strategy with the
  maintainers. Otherwise, you risk doing a lot of work for nothing!

- **Prioritize understanding over cleverness.** Write code clearly and concisely. Remember that source code usually gets
  written once and read often. Ensure the code is clear to the reader. The purpose and logic should be obvious to a
  reasonably skilled developer, otherwise you should add a comment that explains it.

- **Follow existing coding style and conventions.** Keep your code consistent with the style, formatting, and
  conventions in the rest of the code base. When possible, these will be enforced with a linter. Consistency makes it
  easier to review and modify in the future.

- **Include test coverage.** Add unit tests or UI tests when possible. Follow existing patterns for implementing tests.

- **Update the example project** if one exists to exercise any new functionality you have added.

- **Add documentation.** Document your changes with code doc comments or in existing guides.

- **Use the repo's default branch.** Branch from
  and [submit your pull request](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request-from-a-fork)
  to the repo's default branch. Usually this is `main`, but it could be `dev`, `develop`, or `master`.

- *
  *[Resolve any merge conflicts](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/resolving-a-merge-conflict-on-github)
  **
- that occur.

- **Promptly address any CI failures**. If your pull request fails to build or pass tests, please push another commit to
  fix it.

- When writing comments, use properly constructed sentences, including punctuation.

- Use spaces, not tabs.

## :memo: Writing Commit Messages

Please write a brief yet informative commit message.

You can use the following suffix not only limiting to the below-mentioned to improve commit understandability.

- `feat:` -> while adding a new feature or test case
- `add:` -> while adding support files
- `fix` -> when fixing a bug
- `update` -> when updating a piece of code

## :white_check_mark: Code Review

- **Review the code, not the author.** Look for and suggest improvements without disparaging or insulting the author.
  Provide actionable feedback and explain your reasoning.

- **You are not your code.** When your code is critiqued, questioned, or constructively criticized, remember that you
  are not your code. Do not take code review personally.

- **Always do your best.** No one writes bugs on purpose. Do your best, and learn from your mistakes.

- Kindly note any violations to the guidelines specified in this document.

## :nail_care: Coding Style

Consistency is the most important. Following the existing style, formatting, and naming conventions of the file you are
modifying and of the overall project. Failure to do so will result in a prolonged review process that has to focus on
updating the superficial aspects of your code, rather than improving its functionality and performance.

For example, if all private properties are prefixed with an underscore `_`, then new ones you add should be prefixed in
the same way. Or, if methods are named using camelcase, like `thisIsMyNewMethod`, then do not diverge from that by
writing `this_is_my_new_method`. You get the idea. If in doubt, please ask or search the codebase for something similar.

When possible, style and format will be enforced with a linter.
