Micro routing system like expressjs

light.js is simplest micro framework, with minimal npm package

How you can use it ?

1. Create empty project
2. Clone this repo
3. Run npm install path-to-regexp && node sample.js

path-to-regexp only 1 package is used in light.js

You can create new route with .setRoute(path, method, handler) or .get(path, handler) -> .post(), .put(), .patch(), .delete()}

You can get params from 'GET, POST, PUT, PATCH, DELETE' request like this:

 app.post('/product/:id/update', (req, res) => {
     // req.params is contain params

     let getRequestParams    = req.params.get;  // object,
     let postRequestParams   = req.params.post; // object
     let putRequestParams    = req.params.post; // object
     let patchRequestParams  = req.params.post; // object
     let deleteRequestParams = req.params.post; // object
     
 })

-- You can use custom res methods like 'send(data, {status: 200, contentType: 'text/html''})', 'json(object, {status: 200, contentType: 'application/json''})' or 'notFound(data)'

1. .send()

    server.get('/', (req, res) => {
        return res.send('Hello, World !', {status: 200});
    })

2. .json()

    server.get('/', (req, res) => {
        return res.json({'message': 'Hello, World !'}, {status: 200});
    })

3. .notFound()

    server.get('/getProduct/:id', (req, res) => {
        ... You code here
        
        if(!item.exists())
           return res.notFound(`product with id: ${req.params.get.id} not found`, {status: 404});
    })

Default server port is 3000, but you can change it server.listen({port: 4000});
