angular - 在Firebase云功能中部署NestJS

我想用ssr部署angular应用程序。我最近发现，有一些 Angular nestjs示意图可以自动添加ssr功能，但是我没有找到有关如何部署此项目的任何教程或说明，因此可以得到ssr。

我的步骤是:

使用cli创建一个新的 Angular 应用程序。

通过“ng add @ nestjs/ng-universal

添加nestjs

添加云功能并使用Firebase cli托管oji

构建一切

我将如何部署它，以便该应用程序将位于托管功能上，而nestjs服务器位于云功能上，并将被调用以进行预渲染。

最佳答案

使用webpack转换firebase deploy文件后，您只需点击index.js。同样，您可以为此建立管道。

处理函数应如下所示:

import * as express from 'express';
import * as functions from 'firebase-functions';
import { AppModule } from './app.module';
import { Express } from 'express';
import { ExpressAdapter } from '@nestjs/platform-express';
import { NestFactory } from '@nestjs/core';

const server: Express = express();

// Create and init Nest server based on Express instance.
const createNestServer = async (expressInstance: Express) => {
  const app = await NestFactory.create(
    AppModule,
    new ExpressAdapter(expressInstance)
  );
  app.listen(4048);
};

createNestServer(server);
exports.angularUniversalFunction = functions.https.onRequest(server); // Export Firebase Cloud Functions to work on

正如您所写，您一切正常，我假设您知道如何为SSR设置所有其他工具。在其他情况下，请检查此演示存储库https://github.com/kamilmysliwiec/universal-nest

基于@TayambaMwanza问题，我还添加了(与服务器相关的)Webpack配置:

/* Custom webpack server properties. */
const dotenv = require('dotenv-webpack');
const nodeExternals = require('webpack-node-externals');
const path = require('path');
const webpack = require('webpack');
const WebpackConfigFactory = require('@nestjs/ng-universal')
  .WebpackConfigFactory;

// Nest server's bundle for SSR.
const webpackConfig = WebpackConfigFactory.create(webpack, {
  server: './server/main.ts'
});

// Ignore all "node_modules" when making bundle on the server.
webpackConfig.externals = nodeExternals({
  // The whitelisted ones will be included in the bundle.
  whitelist: [/^ng-circle-progress/, /^ng2-tel-input/]
});

// Set up output folder.
webpackConfig.output = {
  filename: 'index.js', // Important in terms of Firebase Cloud Functions, because this is the default starting file to execute Cloud Functions.
  libraryTarget: 'umd', // Important in terms of Firebase Cloud Functions, because otherwise function can't be triggered in functions directory.
  path: path.join(__dirname, 'functions') // Output path.
};

// Define plugins.
webpackConfig.plugins = [
  new dotenv(), // Handle environemntal variables on localhost.
  // Fix WARNING "Critical dependency: the request of a dependency is an expression".
  new webpack.ContextReplacementPlugin(
    /(.+)?angular(\\|\/)core(.+)?/,
    path.join(__dirname, 'apps/MYPROJECT/src'), // Location of source files.
    {} // Map of routes.
  ),
  // Fix WARNING "Critical dependency: the request of a dependency is an expression".
  new webpack.ContextReplacementPlugin(
    /(.+)?express(\\|\/)(.+)?/,
    path.join(__dirname, 'apps/MYPROJECT/src'), // Location of source files.
    {}
  )
];

webpackConfig.target = 'node'; // It makes sure not to bundle built-in modules like "fs", "path", etc.

module.exports = webpackConfig; // Export all custom Webpack configs.
