How to Structure a Pull Request Template That Actually Helps

Creating a pull request (PR) should be a straightforward process, but poorly structured PRs can make collaboration frustrating. A well-structured pull request template can facilitate clearer communication among team members and streamline the review process. This post will guide you through creating a pull request template that actually helps your team.

Why Use a Pull Request Template?

Pull request templates provide a standardized format for contributors to follow. This consistency can lead to:

• Fewer misunderstandings: Clear guidelines help reviewers know what to expect.
• Better context: Contributors can provide necessary details that might be overlooked otherwise.
• Streamlined reviews: Reviewers can quickly find the information they need to approve or request changes.

A good template saves time and enhances collaboration.

Key Sections of a Pull Request Template

When crafting your pull request template, consider including the following sections:

1. Why

This section should explain the motivation behind the changes being proposed. Here, contributors can provide context that justifies the work done.

### Why
- Fixes bug #1234 that caused the application to crash on login.
- Improves performance by optimizing the image loading process.

2. What Changed

Detailing what has changed in the codebase is crucial for reviewers. This section can include a summary of the modifications and any relevant links to issues or discussions.

### What Changed
- Refactored the login component to use hooks instead of class components.
- Updated the image loading logic to use lazy loading.
- Added unit tests for new functionality.

3. How to Test

It’s essential to guide reviewers on how to test the changes. This can include setup instructions, commands to run, or specific scenarios to evaluate.

### How to Test
1. Pull the latest changes from the `feature/login-optimization` branch.
2. Run the following command to start the application:
   ```bash
   npm start
   ```
3. Navigate to the login page and attempt to log in with valid and invalid credentials.
4. Verify that images load correctly and the performance is improved.

4. Risk

Every change carries some risk. It’s important to acknowledge any potential issues that may arise from the changes made. This section can also include mitigation strategies.

### Risk
- Potential for breaking changes in the login flow.
- If any images fail to load, it may impact user experience.
- Mitigation: Extensive testing has been conducted, and a rollback plan is in place.

5. Screenshots

Visual aids can significantly enhance the review process. Providing screenshots can help reviewers see the changes in action rather than just reading about them.
