How can I speed up GitHub Actions workflows for Node.js projects without sacrificing reliability?

Body

I'm working on a Node.js project with GitHub Actions for CI/CD, and while the workflows are reliable, they’re a bit slow, especially on large pull requests.

I’m looking for strategies to speed things up without compromising reliability:

How can I optimize dependency caching?

Are there specific ways to optimize Node.js build and test steps?

Should I parallelize certain tasks, like linting, testing, and building, or use matrix strategies?

Any other tips for reducing build times in a Node.js environment?

Any advice or best practices would be much appreciated!

To speed up Node.js workflows in GitHub Actions:

Cache dependencies using actions/cache to avoid reinstalling packages.

Parallelize tasks with matrix builds for separate jobs (e.g., lint, test, build).

Use --prefer-offline in npm/yarn to avoid unnecessary network calls.

Run tests selectively using paths filters or only on changed files.

Optimize Node.js builds by using ci for npm install instead of install.

These tweaks should significantly reduce build times!
