Vite: custom tsconfig paths are not respected when I pass getLoadContext to the Cloudflare Proxy plugin

[dimik]

Reproduction

According to the docs i have to pass getLoadContext to remix

You must pass in getLoadContext to both the Cloudflare Proxy plugin and the request handler in functions/[[path]].ts, otherwise you'll get inconsistent load context augmentation depending on how you run your app.

I have a path setting in the tsconfig.json

{
 ...
  "compilerOptions": {
    ...
    "paths": {
      "~/*": ["./app/*"]
    },
  },
}

This is my vite.config.ts:

import path from 'node:path';

import { vitePlugin as remix, cloudflareDevProxyVitePlugin as remixCloudflareDevProxy } from '@remix-run/dev';
import { installGlobals } from '@remix-run/node';
import { defineConfig } from 'vite';
import tsconfigPaths from 'vite-tsconfig-paths';

import { getLoadContext } from './load-context';

installGlobals();

export default defineConfig({
  resolve: {
   // This also doesn't help
    alias: {
      '~/': path.resolve(__dirname, 'app/'),
    },
  },
  // this fails with "Error [ERR_MODULE_NOT_FOUND]: Cannot find package '~' imported from ..."
  plugins: [tsconfigPaths(), remixCloudflareDevProxy({ getLoadContext }), remix()],
});

It would be useful to see your full tsconfig.json and package.json.
I ran into a similar issue but solved it since, I just can't remember how but I think it had to do with tsconfig.json and/or package.json.

[Jackardios]

I faced the same problem. I think this is due to the fact that vite does not allow the use of tsconfig paths in vite.config.ts

[emirefek]

any update on this? I can't use paths.

[arielvieira]

Here are a couple workarounds for this.

1. You can use nodemon to build the remix app and start the wrangler every time there's a file change, but that won't have HMR.

// package.json
"build": "remix vite:build",
"start": "wrangler pages dev ./build/client",
"preview": "npm run build && npm run start",
"dev": "nodemon --watch ./app/** --watch ./load-context.ts --ext js,json,ts,tsx --exec \"npm run preview\"",

2. Use hono and its @hono/vite-dev-server plugin instead of the native remix cloudflareDevProxyVitePlugin to run the dev server.
   Here's the example on how to use hono as a dev server in remix: https://github.com/yusukebe/hono-and-remix-on-vite
