Question 1

How to get started with GitHub Actions Toolkit for a TypeScript action?

Accepted Answer

Use the TypeScript Action Walkthrough template linked in the README, which includes setup for compilation, testing, and publishing. Install packages like @actions/core and follow the async function pattern to handle inputs and outputs.

Question 2

GitHub Actions Toolkit vs writing custom shell scripts for simple tasks?

Accepted Answer

The toolkit provides standardized, error-handled utilities that integrate seamlessly with GitHub's ecosystem, while custom scripts might be faster for one-off commands but lack robustness for complex actions. For simple tasks, evaluate if the overhead is worth it.

Question 3

How to cache dependencies between workflow runs using @actions/cache?

Accepted Answer

Specify a cache key based on files like package-lock.json and use the save and restore functions. The toolkit handles the caching logic to reduce download times, but ensure your key is unique to avoid conflicts in shared workflows.

Question 4

Best way to handle errors and logging in a custom action?

Accepted Answer

Use core.setFailed to mark the action as failed and core.error for detailed logs, wrapping code in try-catch blocks as shown in the walkthrough examples. This ensures failures are properly reported in the GitHub UI.

Question 5

How to make HTTP requests to external APIs in an action?

Accepted Answer

Use the @actions/http-client package, which is optimized for actions. It supports async requests and response handling, but for complex APIs, you might need additional error handling and retry logic.

Question 6

GitHub Actions Toolkit or Docker actions for better performance?

Accepted Answer

Docker actions can be more flexible for multi-language setups, but the toolkit adds Node.js overhead. For JavaScript-heavy actions, the toolkit simplifies development, while Docker might be better for isolation or when using other runtimes.
