anyone know if it's possible to speed up the launching of my typescript build step in vscode? for some reason it takes like 3 seconds to launch, idk if it's recompiling unnecessarily or something before executing?

If you want to run the typescript directly, you could try node 23’s typescript support— it could certainly be faster and might not give you headaches with source mapping in your debugger

Not sure if it’s related, but if you are using a bloated version of zsh like oh-my-zsh and it’s set as the default shell, then that could add a second where bash is instant.

jchmoe.bsky.social•141 days ago

this was my guess as well, could be worth checking what part of these 3 seconds is the command shell startup

freya.bsky.social•141 days ago

not sure how to tell! but I don't think I have any fancy cmd stuff installed, and the typescript watch startup is pretty much instant from what I can tell

jchmoe.bsky.social•141 days ago

If you're on linux/mac and using zsh, you can time the startup (and shutdown) of an empty shell with

time zsh -i -c exit

(or adjust the command for different shells)

Not sure how to do this on Windows though..

I need an agent that will just work on optimizing my typescript tsconfigs frfr

Incremental builds and tsc -b might help if not already used

freya.bsky.social•141 days ago

idk what tsc -b means!

rajsite.com•141 days ago

The wireit docs are where I first learned about that ts config: https://github.com/google/wireit?tab=readme-ov-file#typescript

tsx is compiling with esbuild so running tsc -watch in background is not helping?

freya.bsky.social•141 days ago

I guess not? I have it running already, assuming this is the same thing

h4s.one•141 days ago

Yeah it's confusing but no tsx is not using the compilation result from tsc.

Your run script is pointing to the source ts file, not output of tsc. So tsx needs to compile files again with esbuild.

It's actually fine to do this. Esbuild is much faster compared to tsc.

Installing `tsx` into your repo and having a npm script that you run with `node --run {script_name}` instead of using `npx` should help a fair amount!

colelawrence.com•141 days ago

Also a good idea. I’m not sure how fast npx is at resolving where to execute the bin script

freya.bsky.social•141 days ago

what does npm script mean in this case?

dominik.meca.sh•141 days ago

There's a script section in the package.json file. You can define an entry with a name and a shell command. The command has access to CLIs installed in node_modules.

npx does some weird stuff in the background making it slow. VSCode should have support for running npm scripts from tasks.

paulcnova.dev•141 days ago

I think going thru 'npx' could also be taking longer than just 'tsc' because 'npx' is a much larger program that has to figure out what youre asking for while 'tsc' is just the straightforward default compiler no middleman involved. You can get 'tsc' by using:

npm install -g typescript

I'm already running tsc in the background! but I solved it regardless:

Hey have u considered visiting the typescript discord server ?

freya.bsky.social•141 days ago

I probably should!

ragnar-oock.bsky.social•141 days ago

I see that you've solved the issue with build time, but you might be able to speed it up even faster if you are ok with doing type checking and transpilation separately. For that you can use esbuild to build and the LSP for type checking in the editor.

ragnar-oock.bsky.social•141 days ago

Esbuild can get you to build time in the 2 digit milliseconds, it's absurd.
And Rolldown / OXC is supposed to be even faster than that.

freya.bsky.social•141 days ago

wait why am I not just running the compiled Build.mjs file

freya.bsky.social•141 days ago

oh because package/module resolution nightmares it seems okay

freya.bsky.social•141 days ago

oh! it wasn't that difficult to resolve, it was just some path issues when using the built Build.mjs!

this is much better, building is now 1 second instead of 4 seconds c:

If you're running typescript in node.js, I've been using Bun for my ts projects and really enjoying the speed!
