Introduction

Component based node server architecture that is dockerized and ready for deployment

Installation

• clone the repo and then cd NODE-SERVER

Setup docker environment

• Create .env file which will be consumed via docker-compose.yml

  • nano .env and paste the following variables

        # will be used by only in docker file to inject variables in docker-compose.yml
        # port will set by docker only
        PORT=5050
        DB_PORT=5090
        DB_NAME=node_db
        DB_USERNAME=username
        DB_PASSWORD=password
    
        BASE_URL=https://localhost:5090/
        KEY_PATH=server.key
    

    REDIS_PASS=NODE_dev_redis
    

    
    - **NOTE:** all these variables will only be consumed via `docker-compose.yml` file and will not affect the code.
    - `BASE_URL` is the url which our node app is running
    - `PORT` is the port which app will be running on via `docker-compose up` **(this value can be changed as you want)**
    - `DB_PORT` is the port will be exposed to your `localhost` incase you want to connect to db vai any tool _eg. no sql booster_ **(this value can be changed as you want)**
    - Other variables is straight forward to conclude.
    

• Create docker.env file which you will be using in code in docker environment

  • nano docker.env and paste the following variables

            # will be used in code in docker environment
    
            DB_HOST=NODEdb
            DB_PORT=27017
            DB_NAME=node_db
            DB_USERNAME=username
            DB_PASSWORD=password
            jwtPrivateKey=123
    

        REDIS_PASS=node_dev_redis
        # should be the redis container name
        REDIS_HOST=cache
    
        BASE_URL=https://localhost:5050
        KEY_PATH=server.key
    

    
    - `BASE_URL` is the url which our node app is running
    - `DB_HOST` is the name of the host of our db in docker environment.
    - `DB_PORT` is the port which we will use to connect to db via code.
      - **NOTE** This port value should be _27017_ cuz we are connecting to the image(NODEdb) itself not the mapping port in our host(localhost)
    - Other variables is straight forward to conclude.
    

• Happy coding via docker-compose up

  • Your app is running and accessible on localhost:${PORT} => which comes from .env file
  • Your app is running and accessible on mongodb://${DB_USERNAME}:${DB_PASSWORD}@localhost:${PORT}/?authSource=admin => which comes from .env file

Setup local environment

If you want to run local/debug but on same db on docker follow the below steps 👇 👇

• Create local.env file which you will be using in code in local/debug environment

  • nano local.env and paste the following variables

           # will be used in code in local and debug environment
    
          PORT=6060
          DB_HOST=localhost
    
            # should be exactly as DB_PORT in .env when running on docker db
            #                but if we want to connect to local mongo host should be 27017
            DB_PORT=5090
            DB_NAME=node_db
            DB_USERNAME=username
            DB_PASSWORD=password
            jwtPrivateKey=123
    
            REDIS_PASS=NODE_dev_redis
            REDIS_HOST=localhost
    
            BASE_URL=https://localhost:5090/
            CERT_PATH=server.cert
            KEY_PATH=server.key

    • To work with redis you will need to run the compose(at least the redis service)
    • PORT is the port which app will be running on in local/debug mode (this value can be changed as you want)
    • BASE_URL is the url which our node app is running
    • DB_HOST is the name of the host of our db in local/debug mode.
    • DB_PORT is the port which we will use to connect to db via code.
      • NOTE This port value should be same as DB_PORT in .env file cuz we are connecting to the db which is running on the image(NODEdb).
    • Other variables is straight forward to conclude.

If you want to run local/debug but on the host db

• Do the last steps in setting up local.env file but change the DB_PORT to 27017

• Happy coding via npm run local/ debug mode by F5

Configuration environment

ADMIN CREDENTIALS

• ADMIN_USERNAME: is the admin login phone number and must to be a valid mobile
• ADMIN_PASSWORD: is the admin login password
