Slow code suggestions in Telegraf 4.16.X after update

[UMember]

Issue: After updating Telegraf to version 4.16.X in VS Code, there is a noticeable slowdown in code suggestions. This issue was not present in version 4.15.3.

Steps to reproduce:

1. Update Telegraf to version 4.16.X in VS Code.
2. Observe the delay in code suggestions.
3. Downgrade to version 4.15.3.
4. Notice that code suggestions work normally with version 4.15.3.

4.14.0.mp4

4.16.3.mp4

Expected behavior: Code suggestions should be as responsive as they were in version 4.15.3.

Additional information: Other users have reported similar issues after updating Telegraf. Some improvements were observed by disabling certain settings in tsserver LSP, but the problem persists.

Versions:

• VS Code: 1.87.1 / 1.85 / 1.86
• Node js: 21.7.1 / 21.5.0
• Telegraf: 4.16.X (affected), 4.15.3 (not affected)
• Operating System: Windows

Possible solution: Investigate potential compatibility issues with extensions or configurations in tsserver LSP that may be causing the slowdown.

Note: Any help or insights to resolve this issue would be greatly appreciated. Thank you!

Also getting this issue, tsc execution time for whole project increased from 3sec to 14sec after telegraf upgrade. Its almost impossible to work with such slow code suggestions and typescript annotations

Have you tried setting "skipLibCheck": true in tsconfig.json?

I am also facing the same even with previous version too. Even suggestion for local files taking too much time. Just remove the telegraf and see how fast is this. Again add and u will find the slowness. I have just checked the github codespace and found the same issue, Do we have any way to debug this.

I see; thanks @t7yang! GetMsg provides accurate types for ctx.msg. I'll have to think about whether it's optimisable.
