nodejs graphql micorservice template

A Nodejs project template in Typescript to quickly have microservices built using graphql. Mongo db is used as database

Microservice directory

All microservices are created under src/. Example microservice - src/my-micro-service

Creating a new microservice

1. Copy directory my-micro-service into a new directory say abc-micro-service
2. Change the name field in package.json under abc-micro-service , to abc-micro-service
3. In package.json of the main project, add this abc-micro-service as a local file dependency like

   
    "dependencies": {    
        "abc-micro-service": "file:src/abc-micro-service",
    }
   
   

Graphql Schemas

Graphql schemas are under api-schemas/config.json

Microservice Registration

Microservices are served under a specific path , say /graphql/my-micro-service. For a microservice to start up, register it under src/services/app.ts

import { MAPP as MICROSERVICE1 } from "my-micro-service";

 app.use('/graphql/my-micro-service',
        MICROSERVICE1);

Start the server

npm install
npm start

this will start server at port 3092

Test in browser

Test your microservice(ex:my-micro-service) in browser by hitting http://localhost:3092/my-micro-service
