# Tracking API

It is a tracker API with 2 endpoints. It accepts HTTP requests and identifies unique users who have clicked the http://localhost:3000 url.

The structure of the project:

- `Route` configuration is done to define the requests our API can handle

- `Service` for tasks such as connecting to our database models, and doing queries is done. They can be connected to external services that are required by the specific request if needed.

- `Middleware` is added for running specific request validations before the final controller of a route handles its specifics.

- `Model` is added for defining visitors to facilitate data storage and retrieval.

- `Controller` is created for separating the route configuration from the code that finally (after any middleware) processes a route request, calls the above service functions if necessary, and gives a response to the client.

I have also implemented [reporter app](https://github.com/RaminMammadzada/tracking-report-app) with Angular, which you can see the statistics of visitors in the user interface and can download it as a CSV file on demand. To test it out, you should up and run this API project first.

### Built with the following tech stack

- Typescript
- NodeJS v14.18.x
- npm v6.14.x
- ESlint
- ES6+ module system is used.
- Mocha, Chai for unit testing.
- Sequelize ORM
- MySQL

### Prerequisites
You will need to have the following tech stack installed in your local environment.

- MySQL Ver 8.0.28
- NodeJS v14.18.x
- npm v6.14.x
- Typescript

### Setup

Clone the repo by typing

```
git clone https://github.com/RaminMammadzada/tracking-api.git
```

Cd into the project

```
cd tracking-api
```

Install packages with

```
npm install
```

Create .env file at the root of the project and fill in with the following information:

```
DB_NAME='tracking_api_dev'
DB_USER='your_mysql_username'
DB_HOST='localhost'
DB_DRIVER='mysql'
DB_PASSWORD='your_mysql_password'
```

Create a database with the Sequelize-cli command

```
npx sequelize-cli db:create
```

Migrate models with Sequelize-cli command

```

```

If all is set, you will have a database with the name `tracking_api_dev` created and 1 table called Visitors inside it.

Start server with:

```
npm run start
```

For development you can use the following script:

```

```

It will start running in PORT 3000.
You can test the following endpoints in the http://localhost:3000 url:

The REST endpoints
```
/GET http://localhost:3000/
/GET http://localhost:3000/visitors
```

### Unit tests
