I can't compile with Node and Ts

[Cazs03]

I have tried different configurations to compile my backend project with node and ts

// vite.config.backend.ts

import { defineConfig } from 'vite';
import dts from 'vite-plugin-dts';
import pkg from './package.json' assert { type: 'json' };

export default defineConfig({
  build: {
    lib: {
      entry: './src/backend/server.ts',
      formats: ['es'] /
    },
    rollupOptions: {
      external: [
        ...Object.keys(pkg.dependencies), 
        /^node:.*/ // don't bundle built-in Node.js modules (use protocol imports!)
      ]
    },
    target: 'esnext' // transpile as little as possible
  },
  plugins: [dts()] // emit TS declaration files
});

Runing: "build:backend": "vite --config vite.config.backend.ts build", _but i got
building for production...
[plugin:vite:resolve] [plugin vite:resolve] Module "fs" .........
[plugin:vite:resolve] [plugin vite:resolve] Module "path .....
error during build:
[vite]: Rollup failed to resolve import "fsevents"
.........._
A long list of similar errors

I'm not sure about your requirement, but Vite ssr build might fit your use case better https://vite.dev/config/build-options.html#build-ssr Maybe something like:

export default defineConfig({
  build: {
    ssr: './src/backend/server.ts'
  },
  ssr: {
    // probably default works
    // external: ...
    // noExternal: ...
  },
  // not sure dts would work though
  plugins: [dts()] // emit TS declaration files
});
