Contributing to GraphQL-Flutter

We would love for you to contribute to graphql-flutter and help make it even better than it is today! As a contributor, here are the guidelines we would like you to follow:

Got a Question or Problem?

Do not open issues for general support questions as we want to keep GitHub issues for bug reports and feature requests. You've got much better chances of getting your question answered on Stack Overflow where the questions should be tagged with tags flutter and graphql.

Stack Overflow is a much better place to ask questions since:

  • there are thousands of people willing to help on Stack Overflow
  • questions and answers stay available for public viewing so your question / answer might help someone else
  • Stack Overflow's voting system assures that the best answers are prominently visible.

To save your and our time, we will systematically close all issues that are requests for general support and redirect people to Stack Overflow.

If you would like to chat about the question in real-time, you can reach out via our discord channel.

Found a Bug?

If you find a bug in the source code, you can help us by submitting an issue to our GitHub Repository. Even better, you can submit a Pull Request with a fix.

Missing a Feature?

You can request a new feature by submitting an issue to our GitHub Repository. If you would like to implement a new feature, please submit an issue with a proposal for your work first, to be sure that we can use it. Please consider what kind of change it is:

  • For a Major Feature, first open an issue and outline your proposal so that it can be discussed. This will also allow us to better coordinate our efforts, prevent duplication of work, and help you to craft the change so that it is successfully accepted into the project.
  • Small Features can be crafted and directly submitted as a Pull Request.

Submission Guidelines

Submitting an Issue

Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.

We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it. In order to reproduce bugs, we will systematically ask you to provide a minimal reproduction. Having a minimal reproducible scenario gives us a wealth of important information without going back & forth to you with additional questions.

A minimal reproduction allows us to quickly confirm a bug (or point out a coding problem) as well as confirm that we are fixing the right problem.

We will be insisting on a minimal reproduction scenario in order to save maintainers time and ultimately be able to fix more bugs. Interestingly, from our experience users often find coding problems themselves while preparing a minimal reproduction. We understand that sometimes it might be hard to extract essential bits of code from a larger code-base but we really need to isolate the problem before we can fix it.

Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you we are going to close an issue that doesn't have enough info to be reproduced.

You can file new issues by selecting from our new issue templates and filling out the issue template.

Submitting a Pull Request (PR)

Before you submit your Pull Request (PR) consider the following guidelines:

  1. Search GitHub for an open or closed PR that relates to your submission. You don't want to duplicate effort.

  2. Be sure that an issue describes the problem you're fixing, or documents the design for the feature you'd like to add. Discussing the design up front helps to ensure that we're ready to accept your work.

  3. Fork the zino-app/graphql-flutter repo.

  4. Make your changes in a new git branch:

    git checkout -b my-fix-branch beta

  5. Create your patch, including appropriate test cases.

  6. Add and Update the documentation for your feature.

  7. Commit your changes using a descriptive commit message that follows our commit message conventions. Adherence to these conventions is necessary because release notes are automatically generated from these messages.

    git commit -S -a

    Note: the optional commit -a command line option will automatically "add" and "rm" edited files. While the options -S ensures are your commits are signed.

  8. Make sure all of your commits are signed - follow instructions here to learn how to sign your commits.

  9. Push your branch to GitHub:

    git push origin my-fix-branch

  10. In GitHub, send a pull request to graphql-flutter:beta.

  • If we suggest changes then:

    • Make the required updates.

    • Rebase your branch and force push to your GitHub repository (this will update your Pull Request):

      git rebase beta -i
git push -f

That's it! Thank you for your contribution!

After your pull request is merged

After your pull request is merged, you can safely delete your branch and pull the changes from the main (upstream) repository:

  • Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:

    git push origin --delete my-fix-branch

  • Check out the beta branch:

    git checkout beta -f

  • Delete the local branch:

    git branch -D my-fix-branch

  • Update your beta with the latest upstream version:

    git pull --ff upstream beta

Coding Rules

To ensure consistency throughout the source code, keep these rules in mind as you are working:

  • All features or bug fixes must be tested by one or more specs (unit-tests).
  • All public API methods must be documented. (Details TBC).
  • We follow Effective Dart: Style Guidelines.

Commit Message Guidelines

We have very precise rules over how our git commit messages can be formatted. This leads to more readable messages that are easy to follow when looking through the project history. But also, we use the git commit messages trigger releases.

Commit Message Format

Each commit message consists of a header, a body and a footer. The header has a special format that includes a type, a scope and a subject:

<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>

The header is mandatory and the scope of the header is optional.

Any line of the commit message cannot be longer 100 characters! This allows the message to be easier to read on GitHub as well as in various git tools.

The footer should contain a closing reference to an issue if any.

Samples: (even more samples)

docs(changelog): update changelog to beta.5

fix(release): need to depend on latest rxjs and zone.js

The version in our package.json gets copied to the one we publish, and users need the latest of these.

Revert

If the commit reverts a previous commit, it should begin with revert:, followed by the header of the reverted commit. In the body it should say: This reverts commit <hash>., where the hash is the SHA of the commit being reverted.

Type

Must be one of the following:

  • ci: Changes to our CI configuration files and scripts (example: CircleCI)
  • docs: Documentation only changes
  • feat: A new feature
  • fix: A bug fix
  • perf: A code change that improves performance
  • refactor: A code change that neither fixes a bug nor adds a feature
  • style: Changes that do not affect the meaning of the code (white-space, formatting, linting etc)
  • test: Adding missing tests or correcting existing tests

Scope

The scope should be the name of the package affected (as perceived by the person reading the changelog generated from commit messages.

The following is the list of supported scopes:

  • client: For GraphQL Client Package
  • flutter: For updates related to Flutter GraphQL package
  • packaging: For pub dependency updates
  • upgrade
  • changelog

Subject

The subject contains a succinct description of the change:

  • use the imperative, present tense: "change" not "changed" nor "changes"
  • don't capitalize the first letter
  • no dot (.) at the end

Body

Just as in the subject, use the imperative, present tense: "change" not "changed" nor "changes". The body should include the motivation for the change and contrast this with previous behavior.

Footer

The footer should contain any information about Breaking Changes and is also the place to reference GitHub issues that this commit Closes.

Breaking Changes should start with the word BREAKING CHANGE: with a space or two newlines. The rest of the commit message is then used for this.
