Creating Custom Bindings in Phoenix LiveView

The blog by Manos Emmanouilidis at BetterDoc details their venture into enhancing Phoenix LiveView applications by creating custom client-side bindings. Phoenix LiveView has already replaced a substantial part of their software, and they've learned to leverage LiveView's client-side bindings to minimize JavaScript coding. The essence is to write less code, which means fewer maintenance responsibilities. Though the Phoenix team has not provided native support for certain events like mouseover, BetterDoc has devised a method to simulate such events using LiveView's JavaScript commands while waiting for official support. Manos explains a three-step process for this custom implementation: ensuring new DOM nodes capture the custom behavior upon rerendering, executing the JS commands, and avoiding potential future clashes with LiveView's attributes. The solution is a short JavaScript snippet that allows reusing LiveView's JS commands for mouseover events, thereby achieving client responsiveness with minimal custom code.
