Fast CI ⚡

So far in this tutorial you’ve seen how Nx improves the local development experience, but the biggest difference Nx makes is in CI. As repositories get bigger, making sure that the CI is fast, reliable and maintainable can get very challenging. Nx provides a solution.

• Nx reduces wasted time in CI with the affected command.
• Nx Replay’s remote caching will reuse task artifacts from different CI executions making sure you will never run the same computation twice.
• Nx Agents efficiently distribute tasks across machines ensuring constant CI time regardless of the repository size. The right number of machines is allocated for each PR to ensure good performance without wasting compute.
• Nx Atomizer automatically splits large e2e tests to distribute them across machines. Nx can also automatically identify and rerun flaky e2e tests.
