vite build replaces the tsc build files by removing the dist folder

[k4mr4n]

on the package.json scripts:
Im using this "build": "tsc && vite build" to generate the types and the build files.
But as soon as the tsc build finishes the vite build command clears the dist folder and creates js files without any types.
I wonder if there is any good solution to this.

I tried rollup-plugin-typescript2 but it has lots of issues with monorepo setup.

Check if you have emptyOutDir set to true in the vite.config.js. Setting this to false will stop previous files from being removed and just overwrite the newly built files.

return { build: { outDir: './assets', emptyOutDir: false,

Doesn't setting emptyOutDir to false mean that /dist/ will never be emptied?

Is there no startEmpty option?

You understand, right? I want the output to have both the generated *.js files and the types *.d.ts.

Or is that not normal? How are you supposed to build a library? Do I need 2 output targets? One for code and one for types?

This is all very confusing.

So, I didn't understand, clearly. In my case the dts() plugin is removing or preventing the *.js files from the /dist/ folder.

Same issue here. tsc does it's thing but then vite build wipes out the files. I am leaning toward a node script using rimraf to manually get in a clean state before building.

That is... after adding:
export default defineConfig(() => ({ build: { emptyOutDir: false, ...

Looks like if vite is doing the transpiling and tsc is just type checking and producing types, we can just reverse the order...
vite build && tsc?

This worked for me, thanks a lot man, I've been everywhere looking for answers

Is there an explanation somewhere of how to use tsc and vite? As I understand it they should not be writing to the same directory since they will race/fight each other.

Should it not be: src/*.ts => compiled by tsc to build/*.js served by vite for dev and then bundled to dist/

What is not clear to me is how to get my non-TypeScript .js into the (non-git and constantly emptied) build/ directory.
