Recommended Technologies
The purpose of this page is to review the commonly selected technology options when developing user interface applications. To reiterate from the general guidance section:
Keep in mind that like all software, there is no "right way" to build a user interface application. Leverage and trust your team's or your customer's experience and expertise for the best development experience.
Additionally, while some of these technologies are presented as alternate options, many can be combined together. For example, you can use React in a basic HTML/CSS/JS workflow by inline-importing React along with Babel. See the Add React to a Website for more details. Similarly, any Fast web component can be integrated into any existing React application. And of course, every JavaScript technology can also be used with TypeScript!
