Till now we were using the browser to interact with the server, but in this step, any tool or frontend form is must be needed to send data because the browser search bar can only send get requests to receive resources from the server.Įxample: Setting up a route to be accessed by users to send data with post requests.Follow the instructions on screen, using your mobile device to scan the QR code displayed on your browser. We can send data with the request object on the specified path with appropriate HTTP methods. Sometimes we have to send our data to the server for processing, for example when you try to log in on Facebook you send a password and email to the server, Here we will see how to receive data from the user request. app.anyMethod(path, function)Įxample 1: Setting up a basic get request route on the root URL (‘/’ path) of the server. Syntax: The basic syntax of these types of routes looks like this, the given function will execute when the path and the request method resemble.
We can create routes for HTTP methods like get, post, put, and so on. If you’re a beginner you can consider route as a function that gets called when someone requests the special path associated with that function and return the expected value as a response.
Routes are the endpoints of the server, which are configured on our backend server and whenever someone tries to access those endpoints they respond accordingly to their definition at the backend. Step 4: Now we will set all the routes for our application. Now with all of this, we have created and run the server successfully, if your server is not starting then there may be some error, try to analyze and read that error and resolve it accordingly.įinally, after a successful run if you try to open the URL (localhost:3000) on the browser it will show you cannot GET / because we have not configured any route on this application yet. Output: You will see something like this on the terminal. Step to run the application: Now as we have created a server we can successfully start running it to see it’s working, write this command in your terminal to start the express server.
