How to build multiple bundles using Vite similar to Multi Compiler mode(multi config) in Webpack

I have an app which has a main index.html with main.js . But there are also external scripts(libraries) that are injected into index.html programatically from inside main.js . All those scripts(libraries) are built differently because they need different aliases ,plugins ,loaders and folder structure .

In webpack we have Multi-compiler-mode where we can export multiple webpack configs in an array and webpack will build all those different entry points accordingly as specified in respective configs .
Is there a way to do this in Vite? (Library mode doesnt seem to be a solution in this case as i need more than just different module types)

My guess you can make any number of build configs you like and then just run them in parallel with gnu parallel/xargs/gulp:

-c, --config <file>	Use specified config file (string)

https://vitejs.dev/guide/cli.html

The command line could look like that:

find -maxdepth 1 -name vite*.config.*js | xargs -P0 -n1 npx vite build -c

In this case you can have several configs like:

vite.config.mjs
vite.lib.config.js
vite.vendor.config.js

There's also option to parameterize 1 vite config file like described here: https://stackoverflow.com/questions/76517758/how-do-i-completely-disable-chunking-in-vite-and-rollup/76517896#76517896
