How can I configure Vite to allow the 'frontend_web' host in my Docker Compose React setup?

You can solve this by configuring Vite’s built‑in allowed hosts setting in your vite.config.js instead of using an external plugin.

For example, update your vite.config.js like this:

JSCopied
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';

export default defineConfig({
  plugins: [react()],
  server: {
    allowedHosts: ['frontend_web'], // add your Docker service hostname here
  },
});

This tells Vite to allow requests from the “frontend_web” host, which is typically the service name in your Docker Compose file.

Using the built‑in option avoids the resolution issue you encountered with the “vite-plugin-allowed-hosts” package, which appears to have misconfigured entry points. This configuration is straightforward and aligns with Vite’s native support for controlling allowed hosts.
