Handling Multiple requests using Express.js:

Express.js contains multiple methods to handle all types of requests rather than work on a single type of request as shown below:

  • Express.js req.get() Method: This method is used when get request is done by the client for e.g Redirecting another webpage requests etc
  • Express.js req.post() Method: This method is used when post requests are done by the client for e.g. uploading documents etc.
  • Express.js req.delete() Method: This method is used when a delete request is done by the client it is mainly done by the admin end for e.g. deleting the records from the server.
  • Express.js req.put() Method: This method is used when update requests are done by the client to update the information over the website.

// Requiring module 
const express = require("express");

const app = express(); 
  
app.post("/check",(req,res,next)=>{
  res.send("This is the post request")
