I was facing the same issue #37 .
Upon investigation, we found that calling
createProgram
for each HMR was a bottleneck in a project with many module dependencies.So I thought of replacing
createProgram
withcreateWatchProgram
to speed up the re-creation of the compiler API on HMR.You can apply the following patch to reproduce the issue and test the effect of this fix.
(In version 0.3.1 and later, editing
playground/stories/MuiButton.tsx
causes lag in HMR.)Patch for reproduction
