My TS server in VS code is too slow | TypeScript Community | Page 1

I've been working on a react project and the intellisense is slow most of the times. I've tried increasing the total alloted memory size to the server to 4GB. I also added node_modules in exclude list inside tsconfig.json But still the problem isn't solved. Can anyone help me with this

A bit hard to say generically without information

#

There's a general guide to performance, https://github.com/microsoft/Typescript/wiki/Performance - it does have some tools for investigation

GitHub

Performance

TypeScript is a superset of JavaScript that compiles to clean JavaScript output. - microsoft/TypeScript

#

(I would personally not do anything like replace type with interface - it's a theoretical difference in perf, but probably not a make-or-break difference for anything but the largest of projects)

#

Also worth considering if you have any particularly complicated-from-a-type-level libraries that might be creating a lot of work

Actually the project is not that big but the server was very slow. I added this in my settings.json

  "search.exclude": {
    "**/node_modules": true,
    "**/dist": true
  },
  "files.watcherExclude": {
    "**/node_modules/**": true,
    "**/dist/**": true
  }
``` and the performance has increase significantly

Those aren't really related to TS itself, but yeah, other things using resources in your VSCode could probably affect it too

Yess. Thank you for helping out. I will check the resource that you sent 🙂
