In this video you are going to learn how to intercept request and response object in express js using a single middleware function and log each request and response into a file
middleware code
—————————
app.use(function(req, res, next) {
logger.info(req.body);
let oldSend = res.send;
res.send = function (data) {
logger.info(JSON.parse(data));
oldSend.apply(res, arguments);
}
next();
})
apply the above middleware function before calling any route.
