Ignoring all Typescript errors on build

[rodrigojmr]

Hello all.

I'm migrating a large, old app to Vite just to help with the awful build times, this app is changing teams and has not been using TS properly at all, so I'd like to ignore TS errors on build entirely. Is this possible?

The reason, (that can go into a tangent about polyfills, core-js, etc, but feel free to ignore it), is because I'm just trying to get the app to build to se if upgrading old libraries works. As the build keeps stopping at different points of the transformation, I suspect it's due to TS and not, say, issues with core-js. It's also stopped when transforming a date-fns esm file, and I believe that shouldn't happen.

Just an example:

you could remove vue-tsc from the build script

[rodrigojmr]

Sorry, I didn't show the build script. It's literally just
"build: "vite build".

Before it was also:
"build": "tsc-silent -p './tsconfig.json' --suppress @ && vite build". So tsc itself suppresses errors, but vite's build seems to throw errors, even if docs say otherwise (just checked):

Vite only performs transpilation on .ts files and does NOT perform type checking.

@rodrigojmr did you solve it?

[rodrigojmr]

Hey @didiraja I probably should've marked this as closed - I don't recall how I solved it and I probably had something incorrect on my config and you should follow the vite docs, which state that vite itself does not perform type checking.

It assumes type checking is taken care of by your IDE and build process

Please how did you solve this

I have this problem too

[devtest112494]

I have a file vite.config.ts, so I changed typescript to false
import { defineConfig } from 'vite'; import react from '@vitejs/plugin-react';
import checker from 'vite-plugin-checker';
export default defineConfig({ plugins: [
checker({ typescript: false }), react()
]})

For me I had the build command tsc && vite build. I removed the tsc && part and it started working

this worked for me.

[sihyeokpark]

this worked for me too. but I wonder what tsc does? Could you explain for me?

[JorensM]

@sihyeokpark

tsc is the TypeScript command that runs a type check on your project and throws an error if there are any type errors.

Edit: I forgot to mention that tsc also compiles the TypeScript files into JS files, but I think that Vite does this also so that's why the build still works without tsc

[Tharak-N]

so, in that case we can give something like this instead of removing tsc
tsc --noEmit && vite build

this might solve the issue, instead of skipping type check on the project.

@JorensM Oh thank you soo much.... 😍

[Ebrahim-Ramadan]

removed the tsc -p && or tsc && from the build command in package.json
