question: Using Typedi with Vite - Returning ContainerInstance2 about typedi

[attilaorosz]

I have no experience with vite but the container instance is injected as the last parameter always, so it seems like your service is not recognized for some reason. Could you please setup a repo where we could test?

I ran into a similar problem, it is because esbuild (it is used under the hood in vite) intentionally does not support emitDecoratorMetadata (evanw/esbuild#257), this causes decorators to not work.

I was helped by the solution https://github.com/anatine/esbuildnx/tree/main/packages/esbuild-decorators

This works for me.

import { esbuildDecorators } from '@anatine/esbuild-decorators';

export default defineConfig(() => {
  return {
    ...
    optimizeDeps: {
      esbuildOptions: {
        plugins: [
          esbuildDecorators({
            tsconfig: 'tsconfig.app.json',
          })
        ],
      }
    }
  };
});
