express router add middleware

Comment

var app = require("express")();

//This is the middleware function which will be called before any routes get hit which are defined after this point, i.e. in your index.js
app.use(function (req, res, next) {

  var authorised = false;
  //Here you would check for the user being authenticated

  //Unsure how you're actually checking this, so some psuedo code below
  if (authorised) {
    //Stop the user progressing any further
    return res.status(403).send("Unauthorised!");
  }
  else {
    //Carry on with the request chain
    next();
  }
});

//Define/include your controllers

Comment

1)Express app receives a request when someone hits a server for which it will create
request and response.
2)middleware is used to manipulate request.
3)It is middleware because it is a function that run between request and response cycle.
4) middleware stack. middleware that appear first will run first.
5)middleware is like pipeline which end with response object.
//Creating own middleware
//this middleware apply to each and every request
//so,  if we put in last then it will not work.
app.use((req,res,next)=> {
     console.log('Hello from middleware')
     next() 
})
//adding request time 
app.use((req,res,next)=> {
     req.requestTime= new Date().toISOString() //this is method and we need to call that
     next()
})
