v1.0.2

Highlights

CommonJS TypeScript projects now run the way tsc would build them:

• import/export in a CommonJS package runs as CommonJS when tsconfig compiles it to CommonJS. Its exports are no longer frozen, so mock.method() from node:test works on them (#911, closes #905).
• package.json "type" decides the format of .ts files under module: node16/node18/nodenext. A package with no "type" is CommonJS, as in tsc (#908, fixes #907).
• Files whose only imports/exports are type-only run as CommonJS, as Node.js type stripping does (#910, fixes #909).

Also:

• Faster startup: fewer filesystem calls while resolving modules, about 5–12% less time in the PR's benchmarks (#913).
• oxnode watch on macOS no longer reopens folder watches when folders are replaced, which made memory grow without limit (#921, closes #906).
• Embedders using the crate without the napi feature get initialize_loader_js and freeze_tsconfig_js back (#895).

Features

• feat(core): compile ES module syntax to CommonJS where tsc would (#905) by @darcyrush in #911
