It’s time to write some code for creating actual operations. It returns true if the object has all the valid properties otherwise, it will return false. Basically, it checks object properties of Employee object. ![]() By default, I have put one record there.Īnother common JavaScript function we are going to use for validation of employee object. Basically, it contains an array of employee objects. Here you can see it is an array of JavaScript objects of employees. Following is code for our employee's object. Since this application is for demo purpose only we are not going to use any database for that and we are going to use a static JavaScript object for our CRUD operations. Now let’s add some common JavaScript code which we are going to use through out whole application. Here we are creating express object with require syntax and then use that app object to create a router and then we have created a port and our app is listening on that port. Here you can see this code is pretty standard code for any express application. Now let’s create a file called API.js and put following JavaScript code into that.Īpp.use(bodyParser.urlencoded()) With Visual Studio code, You can directory open command line via clicking on Ctrl + `Shortcut and then you can run any commands there like following. Now once we are done with package.json we need to install node js module via “ npm install”. Express is framework for creating Rest APIs and body-parser is to parse body values in JSON. Here you can see that we are going to use express and body parser npm. Once you open visual studio code create a file called package.JSON and put following JSON content on that. The first thing we need to create an empty folder called NodeJSRestPI folder and then right click and select open with code. Our API will contain four operations CREATE, READ, EDIT and DELETE.Ĭreating Basic Node Express application and common code for REST APIs: You see your compile task executing, and once it’s finished you are right in the debug session.In this blog post, we are going to learn how we can create a basic Rest API with Node.js and Express using Visual Studio code editor. src/index.ts" ,Īnd with that, you are all set up. The folder structure is easy: I have my TypeScript files in src, my output in bin. I use a pretty late ES target (having Node an all), and I use commonjs as module format to work nicely with Node.js. My TypeScript configuration tsconfig.json is pretty standard. So I switched to a mode where I compile TypeScript first, then run debugging on the generated JavaScript files with source maps. But at some point I was stuck and didn’t manage to debug my whole application. I tried to make ts-node work for this setup, and made good progress. ![]() Things might be different if you are using other versions. I’m using Node 9.8, VS Code 1.21 and TypeScript 2.7. Since it took me a while and it requires some steps, I thought I better share that with you. That’s where the magic is supposed to be, isn’t it? So I decided to get started with the complete setup. Or I wrote my Node.js apps in TypeScript using tsc or ts-node. I developed Node apps and used the great debugging possibilities with VS Code. Debugging said apps in Visual Studio Code. ![]() When developing, there’s three things that I absolutely enjoy: ![]()
