Test app to process web request and write to database

Node.js tracker

This is test app that processes web request and writes data to database and json file.

Assignment

Create a Node.js application that

• Responds only on a HTTP route /track.

• Reads the data from request. (There are multiple options: pick the one you seem fit.)

• Appends the data to a JSON file

• If there is a count parameter in the data, the application increments the count value in a database by the value of given count parameter. (The database can be redis, mongodb, mysql, ... pick yourself).

• Has one or more unit test

Installation and running

You will need nodejs and mongodb server.

Clone the repository, open folder and install modules:

git clone [e-mail]:ra100/express-js-test-app.git
cd express-js-test-app
npm install

Run tests:

npm run test

If everything is fine, run the app:

npm run app

Usage

Configuration is in app/config.js, you can change default port (1337), database connection uri, table name and path to json file.

By default app runs on port 1337, open browser http://127.0.0.1:1337/track, every other path will return Not Found status 404.

You can use GET or POST request to send data to /track.

GET /track

You can pass parameters to this request, e.g. /track?log=caladan&count=1&data=atreides. This will be appended t oarray in json file and will increase count value in database by values passed in parameter.

POST /track

You can pass data to this request, e.g.:

{
    "log": "Caladan",
    "count": 1,
    "house": "Atreides"
}

This will be appended to array in json file and will increase count value in database by values passed in parameter.
