Sample Backend Service

Sample Typescript backend service, docker based.

Architecture

Docker compose starts 3 services:

• backend api service (storage-service)
• database (Postgresql)
• Database client (PGAdmin)

Microservices

1. Storage Service

How to run

1. Docker environment
2. Local environment

Docker

From console, run

docker-compose up

Locally

Setup local environment

Install database

1. Install locally postgres
2. create a user:

uid: sample
pwd: sample-pwd

Setup backend

1. install node >= 10.15
2. open console and run

   npm i
   

Init example data

After first boot, goto postgres admin console and execute: db/init.sql

example users:

user: admin
pwd: admin

user: user
pwd: user

Run backend

1. Run in developer mode

   npm run start
   

   3.1 Debug Code

    After start, goto  vscode debug view, and launch "Attach to storage-service"
   

2. Run tests

   npm run test
   

3. Build

   npm run build
   

4. Generate docs

   Open console and run

   npm run generate-apidoc
   

How to test

Postman

Install Postman and use provided collection in ./postman/sample.storage-service.json

Swagger ui

Launch docker (or backend locally) and go to:

http://localhost:8005/apidoc/

Database client

Docker environment provide a PGAdmin 4 container in order to manage database. In order to connect, open a browser and go to:

http://localhost:5050

Then, login with these credentials:

user:pgadmin4@pgadmin.org
pwd:admin

Some docker tricks

1. Using

    volumes:
      - ./storage-service:/usr/local/storage-service
      - /usr/local/storage-service/node_modules/

let you avoid to copy all node_modules dependency from container to host machine
