This is a sample service that accepts data over a REST API and persists/retrieves it using MongoDB.

The nodejs service runs by default on port 80. To overwrite for local usage, set the env var

• MONGO_DB_CONNECTION_STRING - A valid mongodb URI pointing at a running MongoDB instance. Example: mongodb://192.168.1.100:27017/sample
• [OPTIONAL] PORT - A valid port number to run the service on. Defaults to 80.

Requires the following: Node 10, MongoDB 4.x

from src dir (where package.json exists), Run the following:

npm run build

export MONGO_DB_CONNECTION_STRING=mongodb://SOME_MONGO:27017/sample 
export PORT=8123

npm start

From the root dir (where the Dockerfile exists), Run the following:

docker build -t data-persistence-sample .

docker run -it -p 8080:80 -e MONGO_DB_CONNECTION_STRING=mongodb://SOME_MONGO:27017/sample data-persistence-sample

Please refer to the postman collection in the docs folder for quick start.
