I am very new to node js. I am trying to create a simple coap client and server using node js. I could create a server on which a text file resides. I want to access that from the client.

var coap = require('coap');
var str = "";
var req = coap.request("coap://localhost:5683");
req.on("response", function(chunk){
    str +=chunk;    
    console.log(str);   
    chunk.pipe(process.stdout);
});

This code is giving me the output as [object Object]. How do I get the string form of this.

You can use JSON.stringify and JSON.parse to do that. Here the documentation.

for general purpose : JSON.stringify(obj);

if object includes functions : require("util").inspect(obj);

read it here : https://nodejs/en/knowledge/getting-started/how-to-use-util-inspect/
