How can package all node js microservices and start in one command

 

Using npm scripts to start all services

If your microservices are not containerized, you can set up an npm script to run all services with one command.

1. Create an npm script in your root package.json that runs all microservices in parallel using something like concurrently or npm-run-all.

   First, install the necessary package:

   npm install concurrently --save-dev
   

2. 


3. Add a script to your root package.json:

   json:
   {
     "scripts": {
       "start": "concurrently \"npm run start:microservice1\" \"npm run start:microservice2\" \"npm run start:microservice3\"",
       "start:microservice1": "cd microservice1 && npm start",
       "start:microservice2": "cd microservice2 && npm start",
       "start:microservice3": "cd microservice3 && npm start"
     }
   }

4. Run all services with a single command:

   npm start
   

This will start all your microservices concurrently.

There are other ways as well. If if you have rest services in different tech like JAVA aor Python etc. we can use docker compose. 

Check docker compose on this link -> how-can-package-all-microservices-using-docker

Other option could be PM2 -> how-to-use-pm2-to-manage-multiple-node-services
