Yarn add express Step 2: Let us write the first express route. Now, install the express using the following command. Now, initialize the package.json file using the following command. Step 1: Create an express project.Ĭreate one project folder and go inside that folder. Now, let’s head back to our demo project. respond with "hello world" when a GET request is made to the homepage With multiple callback functions, it is important to provide next as an argument to the callback function and then call next() within the function’s body to hand off control to the next callback. The routing methods can have more than one callback function as arguments. If there is some processing to be done that exceeds the ability of your template engine, you can always build your own module to do the processing and return the processed data to your template engine for rendering.In other words, the application “ listens” for requests that match the specified route(s) and method(s), and when it detects a match, it calls the specified callback function. I don't really have any experience with it, so I can't really say for sure, but you might give it a look.Īs far as using template engines to build your pages goes, I think that as long as you are gathering the data on the server side, it is pretty acceptable to use your template engine to insert the data into your pages. There might also be a way to do this with socket.io that would keep you from having to make another route. It sounds like, given your limitations, this might be your only (or at least most reasonable) solution. The main things I would suggest there is that you make sure you aren't in violation of the API provider's terms of use, and that you aren't just creating an open proxy to their API.
I was thinking the same thing about creating another route to specifically get the data with AJAX.
