Question 1

How to set up Danger with GitHub Actions?

Accepted Answer

Integrate Danger with GitHub Actions by adding a step in your workflow YAML file to run the Danger command, configure environment variables for authentication, and define a Dangerfile with your rules. Check the official guides on danger.systems for examples.

Question 2

Danger vs CodeClimate for code review automation?

Accepted Answer

Danger focuses on automating team-specific PR etiquette and norms through custom rules, while CodeClimate provides out-of-the-box static analysis for code quality and security. Danger is more flexible for process enforcement, but CodeClimate offers broader pre-built checks.

Question 3

Does Danger work with GitLab CI?

Accepted Answer

Yes, Danger supports GitLab CI by using CI environment variables; configure it in .gitlab-ci.yml to run Danger during the pipeline. You'll need to set up tokens for API access, similar to other CI systems.

Question 4

Can I use Danger to enforce coding style rules?

Accepted Answer

Danger can enforce coding style by integrating with linters or writing custom rules, but it's not its primary focus. Dedicated tools like RuboCop or Prettier might be better for style enforcement, though Danger can highlight issues based on their output.

Question 5

How to create a custom Danger plugin?

Accepted Answer

Create a custom Danger plugin by writing Ruby code that extends Danger's DSL, defining your rules, and packaging it as a gem. The official documentation on danger.systems provides a guide with examples for development.

Question 6

What happens if Danger fails in my CI pipeline?

Accepted Answer

If Danger fails, it typically means rules were violated, and it reports issues in CI logs, which can be configured to warn or block the PR. This ensures standards are enforced before merging, but may require tuning to avoid false positives.

Question 7

Is Danger suitable for large teams?

Accepted Answer

Yes, Danger is well-suited for large teams needing consistent code review standards, as it codifies norms across contributors. However, managing custom rules and plugins at scale may require additional coordination and maintenance.
