Guide to creating an app

Create app

const { FlareApp } = require("@apnet_vector/flare");

// You can specify the name of the application
const app = new FlareApp('Test App');

Result:

APNET Flare <version>

[Flare] Creating Application...
[Flare] Test App successfully created

Run app on port

// the application will run on port 3000
app.run(3000, () => {
    // you can bind the custom action on successful application startup
    console.log('custom action');
})

Result:

APNET Flare <version>

[Flare] Creating Application...
[Flare] Test App successfully created
[Flare] Application successfully started on 3000
custom action //custom action is started

If you go to localhost:3000 you will see the following message:

Cannot GET /

Create API

First, let's understand the API components in Flare

Endpoints

Endpoints allow you to process requests

const homeEndpoint = endpoint({
    //path to the endpoint
    path: 'home',
    //type of HTTP request
    requestType: 'get',

    middlewares: [
        //your middlewares
    ],

    //Handler function, as in Express
    handler: ({ 
        //Req, res, next - provided by express
        req,
        res,
        next,
        
        //Cookies from request (cookie-parser)
        cookies,
        //Request body (body-parser)
        body,
        
        //Log function from Flare
        log,
     }) => {
        
        //Flare will display from which endpoint the message was sent
        log('message');
        
        //Send a response to the user
        res.json('hello world!')
    }
});

Controllers

Controllers - folders for endpoints, they allow to create convenient and beautifully structured APIs

const rootController = controller(
    //path of controller
    '/city',
    //child endpoints or controllers
    [
        //Connect our endpoint from the previous example
        homeEndpoint,
        
        //Let's create another endpoint as an example
        endpoint({
            path: 'shop',
            requestType: 'get',
            handler: ({
                res
            }) => {
                res.json('hello world from shop!')
            }
        }),
    ]
)

Setup API to the application

app.setupAPI(rootController)

Now let's check the result

On startup, we see the following messages:

[get] [/city/home] successfully added!
[get] [/city/shop] successfully added!

In browser:

http://localhost:3000/city/home:
"hello world!"

http://localhost:3000/city/shop:
"hello world from shop!"

Advanced

To add additional functionality to Express, you will need to access an instance of the Express application (e.g. use HandleBars Engine or express static)

app.getInstance().use(...something...)
