Let's open our React frontend project in Visual Studio Code and install the SignalR client. Enter the following command in the Terminal:

> npm install @aspnet/signalr

Check the version of the @aspnet/signalr package in package.json. If it is before version 3, then run the following command in the Terminal to get a more up-to-date version of this package:

> npm install @aspnet/signalr@next

Note that TypeScript types are included in this package, so there is no separate installation process for these. After a few seconds, the SignalR client will be installed in our project.
