Because of their tight integration with the browser, you must be aware of browser behavior when running browser-based applications. The browser behaviors are guided by web standard technologies and related threats impact any application running in browsers.
This chapter explains best practices for browser-based applications. We start with a definition of browser-based applications. We then outline important threats as well as the main security measures that you should be aware of. We continue with a discussion of OAuth implementations. We go from a JavaScript-only implementation to explaining how a Backend for Frontend (BFF) approach for OAuth provides security benefits.
