Chain Middleware to Create a Time Server
Similar to the last challenge, but now we are chaining 2 functions together. It seems complicated, but it's just javascript.
Instead of responding with the time we can also add a string to the request and pass it to the next function. This is trivial, but it makes for a decent example. The code looks like:
app.get("/now", middleware(req, res, next) {
req.string = "example";
next();
},
function (req, res) {
res.send(req.string); // This will display "example" to the user
});
