作为 Windows 服务启动 nestjs 项目

Question

We used to start Angular and NestJS (based on node.js) projects using Docker containers. This solution was discontinued for various reasons, so we are looking for a way to start these projects at the start of the PC (or on a trigger) and restart the project automatically if a crash occurs.

node-windows

This package builds a Windows service from a node.js project. NestJS being based on node.js, starting it using node.js is done this way (while in the project's folder):

node PATH_TO_PROJECT\node_modules\@nestjs\cli\bin\nest.js start --config.\tsconfig.build.json

The script used:

const svc = new Service({
  name: 'Test',
  description: 'Test',
    script:
      'PATH_TO_PROJECT\\node_modules\\@nestjs\\cli\\bin\\nest.js',
    scriptOptions: [
      'start --watch --config PATH_TO_PROJECT\\tsconfig.build.json',
    ],
  ],
  execPath: 'C:\\Program Files\\nodejs\\node.exe',
});

svc.on('install', function () {
  console.log('installed');
  svc.start();
});
svc.install();

The installation works as intended but in a browser, the server cannot be reached.

Questions

1. Is there a way to use node-windows for a NestJS project?
2. Is it possible to use an absolute path with the nest cli start command? (eg nest start --config ABSOLUTE_PATH)
3. How would you start an Angular project the same way?

Thank you.

Answer 1

am use 'child_process' lib for run command like this

server.js

const { exec } = require("child_process");

exec("npm run start", (error, stdout, stderr) => {
    if (error) {
        console.log(`error: ${error.message}`);
        return;
    }
    if (stderr) {
        console.log(`stderr: ${stderr}`);
        return;
    }
    console.log(`stdout: ${stdout}`);
});

and use node-windows like this

var Service = require('node-windows').Service;
var serviceDetail = require('./servicename')();

console.log(serviceDetail);
// Create a new service object
var svc = new Service({
  name: serviceDetail.name,
  description: serviceDetail.detail,
  script: './server.js'
});
console.log('start building up service name ' + serviceDetail.name);
// Listen for the "install" event, which indicates the
// process is available as a service.
svc.on('install',function(){
  svc.start();
});

svc.install();
