Conversation
Replaced the sequential `for...of` loop in `checkPlugins` with `Promise.all` to execute `plugin.detect()` calls concurrently. This significantly reduces the time required for the detection phase, especially as the number of plugins grows. The results are processed in the original order to ensure deterministic behavior for logging and merging `bundleParams`. Measured improvement: - Baseline (3 plugins, 100ms each): ~311ms - Optimized (3 plugins, 100ms each): ~102ms - Speedup: ~3x for the simulated case.

- Around line 50-73: The test mutates pluginConfig.plugins directly and only
restores it at the end, so wrap the mutation and the assertions in a
try/finally: save originalPlugins, replace pluginConfig.plugins with mockPlugins
before running checkPlugins(), then in the finally block always restore
pluginConfig.plugins using the saved originalPlugins (use the same splice
restoration logic shown); ensure the timing/assertion code (start/await
checkPlugins()/end/expect(duration)... expect(result)...) remains inside the try
so cleanup always runs even on failure.

instead modify the test that calls checkPlugins() to assert concurrency by
instrumenting the three plugin detect implementations (the p1/p2/p3 detect
functions used by checkPlugins()) to set a "started" flag when invoked and then
await a shared gate Promise before finishing; assert all three started flags are
true before resolving the gate to prove they ran concurrently, and keep the
duration / expect(duration).toBeLessThan(...) only as a secondary, non-blocking

Always restore pluginConfig.plugins via finally.
At Line 51, global test state is mutated. If an assertion fails before Line 73, cleanup is skipped and later tests may fail for the wrong reason.

💡 What: The optimization implemented
The
checkPluginsfunction insrc/utils/check-plugin.tswas refactored to usePromise.allfor concurrent plugin detection instead of a sequentialfor...ofloop.🎯 Why: The performance problem it solves
Previously, each plugin's
detectmethod was awaited sequentially. This caused an N+1 async operation bottleneck where the total detection time was the sum of all individual detection times. In environments with multiple plugins or slow filesystem checks, this led to unnecessary delays during the bundling process.📊 Measured Improvement:
Using a simulated benchmark with 3 plugins, each having a 100ms artificial delay:
The optimization ensures that the total detection time is bounded by the slowest individual detection rather than the sum of all. Functionality and side-effect ordering (logging and parameter merging) have been preserved exactly.
