Daily design APIs to add custom features to apps quickly and easily. They compared building new features in apps versus using Chrome extensions, concluding that extensions are suitable for specific problems not requiring app-level handling. The team created a Chrome extension to auto-generate shareable links for screen sharing during calls, aiming to make this process faster. The extension has three steps: adding the Netlify link and saving it to localStorage, creating a new Daily room and launching a meeting with screen sharing enabled, and returning a shareable link that can be used to start the call. The team shared their code and provided tutorials for building the extension, including setting up manifest.json, creating the popup.html file, writing custom JavaScript to handle events, and deploying the extension to Chrome.
