im trying to put a payload limit of 1kb using :
app.use(bodyParser.json({
limit: "1kb" ,
strict:true
}));
its working perfectly as it suppose to work , but the only problem is i get an error of
PayloadTooLargeError: request entity too large

is there any way to handle this error through callback or anything so i show a custom error or send a custom response ?
Have you tried like this
app.use(express.json({limit: '1kb'}));
Parsing request body as middleware is available in Express v4.16.0 onwards.
EDIT
If you want to customise your error message, then you need to define your error-handler middle-ware to do that. Something like this:
// Not tested code.
// Usually added as last middleware
app.use(function (err, req, res, next) {
if(err instanceof PayloadTooLargeError){
//res.status(<your status code>).send(<your response>);
res.status(400).send("Customized Response");
}
else{
next(err);
}
})
