Nest based example of API.
Ports in use: 9000, 9001, 27037.
Microservice gateway contains only ts code. It works on 9000 port, so check if the port is not in use on your machine.
Microservice users contains Mongo DB in docker image and ts code which works on 9001 port. Mongo DB especially runs on 27037 instead of standard 27017 port. This is to avoid conflict with your current project with Mongo in case you have one.
In each microservice (gateway and users folders) rename .env.example to .env. To run gateway:
# gateway
$ cd gateway
$ npm install
$ npm run start:devTo run users:
# users
$ cd users
$ npm install
$ npm run start:dev
$ npm run db:up# up image with mongo DB
$ npm run db:up
# stop image
$ npm run db:stop
# fully remove image
$ npm run db:stopIn Postman: File -> Import... and choose file nest_basics.postman_collection.json. At first run request Create User.
Copy from response field data.user._id and paste it into Params _id of request Get User by Id. Then run request Get User by Id.
