Question

我是node的新手-我创建了service.ts，并尝试使用nodemon build

但我收到错误消息

有人可以解决吗？

我的代码：

nodemon.json

{   "ignore": [
    "src/**/*.spec.ts",
    "**/*.test.ts",
    "**/*.spec.ts",
    ".git",
    "node_modules"   ],   "watch": [],   "exec": "ts-node",   "ext": "ts-node" }

pakage json：

  "scripts": {

    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "sprite": "svg-sprite --config src/sprite-config.json src/svg/*.svg",
    "start:ssr": "npm run build:ssr && npm run serve:ssr",
    "dev:ssr": "ng run stroyka:serve-ssr",
    "serve:ssr": "node dist/stroyka/server/main.js",
    "serve:start": "nodemon server.ts",
    "build:ssr": "ng build --prod && ng run stroyka:server:production",
    "prerender": "ng run stroyka:prerender"   },

server.ts

import 'zone.js/dist/zone-node';

import { ngExpressEngine } from '@nguniversal/express-engine'; import
* as express from 'express'; import { join } from 'path';

import { AppServerModule } from './src/main.server'; import { APP_BASE_HREF } from '@angular/common'; import { existsSync } from 'fs'; import { Express } from 'express';

// The Express app is exported so that it can be used by serverless Functions. export function app(): Express {
    const server = express();
    const distFolder = join(process.cwd(), 'dist/stroyka/browser');
    const indexHtml = existsSync(join(distFolder, 'index.original.html')) ? 'index.original.html' :  'index';

    // Our Universal express-engine (found @  https://github.com/angular/universal/tree/master/modules/express-engine)
    server.engine('html', ngExpressEngine({
        bootstrap: AppServerModule,
    }));

    server.set('view engine', 'html');
    server.set('views', distFolder);

    // Example Express Rest API endpoints
    // server.get('/api/**', (req, res) => { });
    // Serve static files from /browser
    server.get('*.*', express.static(distFolder, {
        maxAge: '1y'
    }));

    // All regular routes use the Universal engine
    server.get('*', (req, res) => {
        res.render(indexHtml, { req, providers: [{ provide: APP_BASE_HREF, useValue: req.baseUrl }] });
    });

    return server; }

function run(): void {
    const port = process.env.PORT || 4000;

    // Start up the Node server
    const server = app();
    server.listen(port, () => {
        console.log(`Node Express server listening on http://localhost:${port}`);
    }); }

// Webpack will replace 'require' with '__webpack_require__' // '__non_webpack_require__' is a proxy to Node 'require' // The below code is to ensure that the server is run only when not requiring the bundle. declare const __non_webpack_require__: NodeRequire; const mainModule = __non_webpack_require__.main; const moduleFilename = mainModule && mainModule.filename || ''; if (moduleFilename ===
__filename || moduleFilename.includes('iisnode')) {
    run(); }

export * from './src/main.server';

[nodemon]应用程序崩溃-等待文件更改，然后再开始...

Answer 1

您正尝试直接使用node启动打字稿应用程序。您应该改用ts-node软件包。运行以下命令进行安装：

npm install --save-dev ts-node

然后在您的package.json脚本部分中，将nodemon server.ts更改为：

nodemon --exec ts-node server.js

nodemon使用带有打字稿的Express
