🙁 Actual behavior
After deleting and regenerating a large amount of auto-generated files, typescript reports an error as seen below when using --watch. This also affects the VS Code tsserver.
src/main.ts:1:32 - error TS2307: Cannot find module './app/services/generated' or its corresponding type declarations.
1 import { TranslationDto } from "./app/services/generated";
🙂 Expected behavior
Typescript should pick up new files even when there are a lot of them.
Additional information about the issue
Reproduction:
- Clone https://github.com/2767mr/tsbug
-
npm install - Open one terminal with
npm run watch - After a few seconds, open another terminal with
npm run copy
Here is the tsserver log that is created when doing this: tsserver.log
Possibly related issues: #57330 #22710 #37514 #54511 (same use case as we have - but on our end it does not work at all instead of being slow)
Note that this bug does not happen if you reduce the amount of files that will be copied by npm run copy
Some more information: I tried to reproduce this again because the blog post for the 5.5-RC mentions something similar to this issue.
I first tried to reproduce it again using v5.4.5 and noticed that the error only occured after I executed npm run copy the second time. From the on, every time npm run copy is executed, the error occurs. Restarting tsc --watch did not help with that.
I then tried to use typescript 5.5.1-rc but the issue still persists.
Something that might also be usefull when looking into this issue: I am using Windows 11 23H2 22631.3672.
Thank you for repro as thats the most helpful and crucial in investigating such issues.
