Turbopack: Share entrypoint template logic between Turbopack/webpack (#82385) ## Goal With three different bundlers, we're often forced to duplicate next.js-specific logic and configuration across two or three different bundlers. E.g. https://github.com/SyMind/next-rspack-binding/ would cause us to duplicate our current externals logic across all three. To help, we'd like to have a shared crate that can be used in a few different ways: - Via turbopack (which is itself called through native napi bindings) - Via direct native napi bindings to JS for webpack - Via wasm bindings to JS for webpack [*(note: ideally these would be replaced with napi's recent wasm support, but it doesn't make sense to do that until after the napi v3 migration is done)*](https://napi.rs/blog/announce-v3#webassembly) - Via Rspack (we'd build a custom binary) The wasm bindings (in their current state) and Rspack cannot (or should not) depend on `turbo-tasks`. However, all of the current `next-*` crates depend on `turbo-tasks`. This introduces a `next-taskless` crate for code that can be isolated from performing IO and that does not need to depend on `turbo-tasks`. Code in this crate can be used from wasm or Rspack. ## This PR As a proof-of-concept, this deduplicates our next.js entrypoint templating logic across webpack and Turbopack. It's a large function that doesn't need to directly depend on file IO. Some path manipulation had to be moved out of `turbo-tasks-fs` to support this, so that code is in `turbo-unix-path`. I'm happy to accept different bikeshedded crate names. ## Testing Tested wasm with: ``` pnpm i pnpm swc-build-wasm --target nodejs pnpm build NODE_TEST_MODE=start NEXT_TEST_WASM=true NEXT_SKIP_NATIVE_POSTINSTALL=1 NEXT_TEST_PREFER_OFFLINE=1 node run-tests.js test/production/pages-dir/production/test/index.test.ts ``` Tested turbopack with: ``` pnpm i pnpm swc-build-native pnpm build pnpm test-start-turbo test/production/pages-dir/production/test/index.test.ts ``` Tested webpack with: ``` pnpm i pnpm swc-build-native pnpm build pnpm test-start test/production/pages-dir/production/test/index.test.ts ```
