We do not need to display anything in the browser because REST APIs are interfaces that are intended for programmatic use, and the error status code is all that is needed.Īnyway, it's possible to give a clue about the reason for sending a 404 error by overriding the default NOT FOUND message. However, the application doesn't return anything to show to the user, like web applications normally do when we visit a page that does not exist. Our application works and sends the error status code if no note is found. However, undefined is falsy meaning that it will evaluate to false. The if-condition leverages the fact that all JavaScript objects are truthy, meaning that they evaluate to true in a comparison operation. Since no data is attached to the response, we use the status method for setting the status and the end method for responding to the request without sending any data. We will answer the questions presented by the utility, and the result will be an automatically generated package.json file at the root of the project that contains information about the project.Ĭonst http = require ( 'http' ) let notes = [ ) Let's navigate to an appropriate directory, and create a new template for our application with the npm init command. In fact, npm originates from the Node ecosystem. We had already mentioned npm back in part 2, which is a tool used for managing JavaScript packages. Notice that the applications and exercises in this part are not all React applications, and we will not use the create-react-app utility for initializing the project for this application. However, let's start with the basics by implementing a classic "hello world" application. Our goal is to implement a backend that will work with the notes application from part 2. The newest version of Node supports a large majority of the latest features of JavaScript, so we can use the latest features without having to transpile our code. The situation with JavaScript running in the backend is different. This is especially helpful when troubleshooting, or to communicate explicitly to your fellow collaborators (or future self) during development and debugging. Please make sure that your version of Node is at least as new as the version used in the material (you can check the version by running node -v in the command line).Īs mentioned in part 1, browsers don't yet support the newest features of JavaScript, and that is why the code running in the browser must be transpiled with e.g. Logging variables: Log variables using console.log () in a script to inspect variables in the Postman console. This course material was written with version v18.13.0 of Node.js. We will be building our backend on top of NodeJS, which is a JavaScript runtime based on Google's Chrome V8 JavaScript engine. I have a nice Gulp setup that will do the various builds and have seen the plug-ins that will easily remove all the console.logs, but nothing I've seen lets me easily mark some console.logs to be retained.In this part, our focus shifts towards the backend: that is, towards implementing functionality on the server side of the stack. Since the platform is new enough, however, I'd like to keep some of those logs to both provide an nice monitor that things are running as expected and to assist in the inevitable trouble-shooting that will be needed once the new code goes live. During development, a lot of console.logs have been used and most of these I want to remove for production deployments. We are establishing a code base on a new platform. ![]()
