# | API mixer |

Simple REST API mixer as a service. A minimal service will be deployed on your local port `8000`, all incoming data has to be sent by _POST_ fields (_e.g. [form-data](https://tools.ietf.org/html/rfc2388), [x-www-form-urlencoded](https://www.w3.org/TR/html5/sec-forms.html#urlencoded-form-data)_). The output is a _application/json_ set.


### Project Set up

##### Prerequisites

You need `node` and `npm` installed. The project is written using `typescript` that allows type checking and other verifications before creating the real javascript code. Also it adds polyfills (c.f. babel) to ECMAScript that allows the use of `class` and other new ES features.

##### 1. Install dependencies

Go into the project's folder and run :
```bash
$ npm i
```

##### 2. Transpile sources

Run the following command inside the project's folder :
```bash
$ npm run build
```

All source files of the `src/` folder will be transpiled into the `dist/` folder.

> It is also possible to watch the typescript while developping and modifying files with the command `npm run watch`.

##### 3. Launch server

> You need to have `node` installed.

Launch the server with the following command (inside the project's folder) :
```bash
$ node dist/main.js
```

### Project fast start

This command will build and run the whole project :
```bash
$ npm run build;
$ npm start;
```

### Test the API

You can now use [Postman](https://www.getpostman.com/) or whatever API client or web browser at `127.0.0.1:8000`. The only allowed request method is **GET** and accepts the research field in a query parameter named 'q'.
The console running the server will provide reactive and real-time details.

Example URL : http://127.0.0.1:8080/?q=Nutella that searches for the keyword "Nutella".

> When called in a browser you will get a simple web page that is the representation of the results (with images).
>
> When called with the header `Accept: application/json`, the result will represent the data as a JSON object.
