That’s it! Now you can start implementing your API or app. If everything is fine, then we should see the output “Server is up and running!”.

In another terminal window (or in the browser) we can check if the server is running.

Great, we are ready to run the server now. $ touch tsconfig.jsonĪdd the following content to this file. Now have to add a file with the TypeScript configuration. $ yarn add express $ yarn add typescript tslint -D It offers a vigorous collection of topographies for both mobile and web applications. In addition, we still need Express to run a Node.js server. What is Express.js Express.js is a small Node.js framework of web application. We don’t need these at runtime and therefore install them as dev-dependencies. Now let’s install the TypeScript dependencies. With the flag -y default settings are used, which should be good for the exemplary implementation. Now we initialize Node in this directory. $ mkdir event-sourcing-example $ cd event-sourcing-example/ Let’s start by setting up a simple Node.js project with TypeScript.įirst we create a new project directory. Before installing, download and install Node.js. And since I don’t want to write it over and over again, I will then simply refer to this article here for those who are not sure how to get to such a TypeScript project. This is a Node.js module available through the npm registry. Why am I writing this very short tutorial? My intention is quite simple to explain: In the future, I will write some articles that need such a project.
