Type file missing when using vue-tsc

[HUST-SE-LY]

Describe the bug

The bug happened when I use webpack with module federation 2.0 to build my Vue App. When I run pnpm start in container folder, A type declaration file is missing from @mf-types.zip in the dist directory.

Then I read the source code, I find in packages/dts-plugin/src/core/lib/typeScriptCompiler.ts, function createHost rewrites the writeFile of typescript,but this looks useless under vue-tsc. Whether it is a component or a function, the following code doesn't seem to execute, and the target .d.ts file cannot be generated. By the way, in vue-tsc, sourceFile.fileName seems to be App.vue.ts, not App.vue, so the following code may be wrong.

// packages/dts-plugin/src/core/lib/typeScriptCompiler.ts
for (const sourceFile of sourceFiles || []) {
      const sourceEntry = mapExposeToEntry[normalize(sourceFile.fileName)];
      if (sourceEntry) {
        const mfeTypeEntry = join(
          mfTypePath,
          `${sourceEntry}${DEFINITION_FILE_EXTENSION}`,
        );
        const mfeTypeEntryDirectory = dirname(mfeTypeEntry);
        const relativePathToOutput = relative(mfeTypeEntryDirectory, filepath)
          .replace(DEFINITION_FILE_EXTENSION, '')
          .replace(STARTS_WITH_SLASH, '')
          .split(sep) // Windows platform-specific file system path fix
          .join('/');
        originalWriteFile(
          mfeTypeEntry,
          `export * from './${relativePathToOutput}';\nexport { default } from './${relativePathToOutput}';`,
          writeOrderByteMark,
        );
      }

@2heal1 do you have any idea here why it is not detected?

Hello,

i have a similar issue by using module federation quick start rsbuild example converted to vue3

[2heal1]

let me check this

[WeetA34]

as mentioned in issue 2685 HUST-SE-LY's comment , it works with latest vue-tsc 1.x (1.8.27). Regarding rsbuild, it doesn't provide vue-tsc by default for vue3 typescript projects as it uses tsc directly to build. So, it would be nice to get the types generated with tsc directly.

[2heal1]

I find vue-tsc@1.7.0 will not use writeFile anymore , so this is the reason why our logic not work .

And the vue-tsc@<1.7.0 also has some questions , as @WeetA34 say , i will try tsc instead to see if it can work

[2heal1]

I check again and find it can not use tsc to compile .vue file .

I will fix the issue by re-implement the ts compile.
