The next step will involve invoking the terminal once again and running the below command as shown in the image below. We will concentrate on the functional part of the application only and not the testing part. It is also worth noting that we get Intellisence support through the help of the testing library. Our application uses a testing library called Testing Library with its React support, and we can know what is going on by reading the file.

Likewise, we have some tests which are also written in TypeScript so that we can get TypeScript information inside our tests. We have App.tsx, we also have index.tsx which is where the application entry point is. On the left sidebar, we have a bunch of files. The Create React App will be launched using the TypeScript template as shown in the image below. Once the template has been downloaded, you’ll be good to go. Next, when prompted “Okay to proceed? (y)” click y and then press the Enter key to install the package. This is going to spin up just like any basic application and the resulting application is going to be what the React community has agreed upon, which is a create-react-app default template. Npx create-react-App App –template TypeScript

To view Create React App, open your terminal, navigate to your workspace directory and run the below command. The flow was developed by Facebook to implement their internal stuff, but a lot more projects are going down the direction of TypeScript than they are with Flow. The reason we have this template flag is to enable us to specify the type safe JavaScript language of our choice, for instance, if you wanted to use something like Flow, which is another approach of doing type safe JavaScript you would. We will give it a name and then we will specify the template and that template will be TypeScript. The installation process will execute and generate the react application. But for a start, we are going to install the Create React App with npx. You will also need an IDE of your choice.Īs far as package management is concerned, we personally prefer npm, so we are going to use npm for this tutorial. For this project, it is a prerequisite to have NodeJS and TypeScript installed on your laptop/system.
