Optimizing build times is crucial for maintaining a fast and efficient development workflow. GitHub Actions allows you to run jobs in parallel, significantly reducing the overall execution time of your workflows. By leveraging matrix builds, you can take full advantage of parallelization. Each combination of your matrix configuration runs as a separate job, independently of others. This means that if you have a matrix with three Node.js versions and three operating systems, all nine jobs can run simultaneously, assuming there are enough available runners. To make the most of this feature, ensure your tests are designed to run independently and avoid unnecessary dependencies between jobs. Parallelization not only speeds up the feedback loop for developers but also improves overall productivity by reducing downtime. By optimizing build times, you can allocate more resources to developing new features and improving your software, rather than waiting for tests to complete.
