vue3 nestjs ssr

Vue 3 and NestJS can be combined to build a server-side rendered (SSR) application. SSR allows Vue application to be rendered on the server before being sent to the client, which provides benefits like better SEO and initial page load performance.

To use Vue 3 with NestJS for SSR, you can follow these steps:

1. Set up a new NestJS project by installing the NestJS CLI globally: `npm install -g @nestjs/cli`
2. Create a new NestJS project using the CLI: `nest new project-name`
3. Install the necessary dependencies for SSR: `npm install vue vue-server-renderer express`
4. Create a new Vue 3 application inside the NestJS project. You can use the Vue CLI to scaffold the Vue application: `vue create client`
5. Configure Vue Router and Vuex as needed for your application.
6. Create a server.ts file in the root of your project and configure an Express server with SSR support. Here's an example:

import 'reflect-metadata';
import { createSSRApp } from 'vue';
import { renderToString } from '@vue/server-renderer';
import * as express from 'express';
import { readFileSync } from 'fs';
import { join } from 'path';

async function bootstrap() {
  const app = express();

  const template = readFileSync(join(__dirname, 'client', 'public', 'index.html'), 'utf-8');
  const serverBundle = require('./client/dist/server.json');
  const appContext = {};

  const renderer = await createRenderer(serverBundle, template);

  app.use(express.static(join(__dirname, 'client', 'dist')));

  app.get('*', async (req, res) => {
    try {
      const appInstance = await createSSRApp(App);
      appInstance.use(router);
      appInstance.use(store);

      await router.push(req.originalUrl);
      await router.isReady();

      const html = await renderer.renderToString(appInstance, appContext);

      res.send(html);
    } catch (error) {
      res.status(500).send('Internal Server Error');
    }
  });

  await app.listen(3000);
}

bootstrap();

Please note that this is a simplified example, and you may need to adjust it based on your specific project structure and requirements. The example assumes you have a `client` folder for your Vue application and that the server-side bundle is generated in `client/dist`.

7. Build your Vue application for production: `npm run build` inside the `client` folder.
8. Start your NestJS server: `npm run start`.

With these steps, you should have a Vue 3 + NestJS SSR application running. Keep in mind that this is just a basic setup, and you can extend it further based on your project needs.
