How to Customise Golangci-lint for Your Project?
You need to customise golangci-lint for your project, which will help you get the best results. This tool allows you to set it according to your needs to check your codes to a high standard.
Configuring Linters in Your .golangci.yml
In your .golangci.yml file, you can choose which lines to use. This file tells golangci-lint what to check. You can turn some linters on or off. For example, you can enable those checks if you care about performance.
You can also set severity levels for each linter. This means you can decide if an issue is a warning, info, or error. By customising these levels, you can focus on the most critical problems. This way, you know what to fix first.
Adjusting Settings for Performance
Performance is critical when using golangci-lint. You can make it faster by changing some settings, such as ignoring specific files or folders. You need to customize golangci-lint for your project, and this will help you get the best results. This tool allows you to set it to your needs. In this manner, you can check your codes to a high standard. If you have third-party code that doesn’t need checking, skip it. This will save time.
You can also limit the number of issues that appear. Setting a maximum number will make you feel safe, and you can focus on the main problems. With these changes, golangci-lint will work better for you.
How to Run Golangci-lint in Your Project?
Running Golangci-lint in your project is easy. It lets problems in your code arise as soon as possible. With just a few simple commands in file checking, it can make your codes clean and efficient.
Running golangci-lint Locally
Open your terminal in your machine. You need to get to the project folder first. Then, in the terminal, you write golangci-lint run. This command will “lint” your code, which means it will scan it and tell you about all the problems it can find.
Once the linting is done, you’ll see a list of problems. Look for warnings or errors in the output. Fix these issues to improve your code quality. Running the linter often helps you catch problems early.
Integrating with CI/CD Pipelines
Your bright future is when you include integrate Golangci-lint into your CI/CD pipeline. Then, you’ll be able to automate linting while reviewing the code. All you’d need to do next is a push; after that, integrate golangci-lint will automatically check on your code.
Add the integrate golangci-lint to your CI configuration file and include the command golangci-lint run in pipeline steps. If issues are found, the build will fail. Thus, only clean code will get merged, keeping the project on track.
