In the previous lesson, you learned about how pull requests can be used to suggest changes to a project. These pull requests not only clearly document your changes, they also allow for collaborators to review the changes and discuss things, prior to them being merged into the main project repo. In this lesson you will learn about issues. Issues can be used to drive or define the content of pull requests. This type of tracking makes managing a GitHub project with multiple collaborators easier and more efficient.
In this lesson we are using the open source model of software contribution as a basis for the workflow that we are describing.
What is a GitHub Issue?
Issues in GitHub are text based descriptions of things that need to be addressed, changed or worked in a project or GitHub repo. GitHub issues can help you manage a collaborative project that you are working on with others. All that you need to create an issue on GitHub is a GitHub login. Issues are written in plain text using Markdown to format the content of the issue.
GitHub issues are an excellent way to keep track of bugs and other items that need to be addressed in a project.
GitHub issues can be used to identify and track:
- Bugs or problems with code in your repo. For example
this thingdoesn’t work as expected.
- Things that are missing in your repo. For example perhaps something isn’t documented correctly.
- Enhancements or new functionality that is needed in the code.
- Documentation updates.
- General questions and discussion points that need to be considered by all collaborators
- and more…
GitHub Issues Can Be Used to Manage Collaborative Projects and To Allow Both Coders and Non Coders to Contribute to a Project
GitHub issues are a way that anyone can identify problems with the code in your project. Not everyone is a programmer or a coder. But sometimes people are using your code and have questions, or find bugs. Issues are a way for others to contribute, regardless of their technical expertise.
Use GitHub Issues To Manage Contributions to Your Project Submitted Using Pull Requests
While you can submit a pull request (PR) at any time, it is best practice to first open an issue to discuss the change before submitted the PR. Opening an issue is ideal for project management as it allows you to keep track of:
- what needs to be impelmented on the project - bugs, enhancements, fixes
- who is going to work on that task
- how the task will be implemented
Finally, when the person responsible for the task submits their PR, they will refernece the issues and associated discussions that occured before and while the work was being done. This becomes a great record of effort on a group project.
Best Practices for GitHub Issues
There are many best practices to consider when submitting issues to a repository. A few include:
- Make The Issue Name Descriptive: It is helpful to have descriptive issue titles that tell the code owners what the issue is about. Descriptive titles become particularly important if there are many issues in a repo.
- Create an Reproducible Code Example (If it iss a code bug): If your issue is about a bug in the code, it’s going to be easiest to understand if the code owners can reproduce the bug. Provide some code that someone can copy and run and see the exact bug that you are seeing.
- Consider Your Tone as You Write: Working with colleagues in a collaborative environment online can be tricky as you don’t have the direct input of people’s facial expressions and response to your comments that you may have in in-person or online meetings. As such, it’s important to consider the tone of the issue as you write it. Rather than being critical and demanding fixes immediately, it is best to constructively point out what is not working and how it could be fixed or address challenges. If your input is well-received by the repo maintainers, it is more likely to be addressed more quickly.
Mention Specific People Using @github-username-here
The last important note is that when possible, it is best to mention the collaborator that you wish to respond to your issue in the text. You can do that by using
@github-username in the text. This mention will draw more attention to the issue that you submitted and is in turn more likely to be responded to.
Create a Pull Request to Address an Issue
Once you have submitted you issue and the everyone who needs to approve the work has chimed in, you will likely be asked to submit a pull requestion. Remember that a pull request is the way for you to suggest changes to a repository that can be reviewed carefully before being merged (combined into the main code base in the repo). When you submit that PR, you will want to add some text to the PR that describes what the changes achieve. You will also want to link back to the original issue that was opened. An example of the beginning of an PR summary may look something like this:
@lwasser this pr addresses issue #125 ... more here about what the pr does
Now you know the fundamentals behind creating issues using GitHub. In the next lesson you will see the larger picture of what a typical GitHub workflow looks like.
