Using Select2 with Phoenix LiveView

​LiveView doesn’t support JavaScript interop at the moment (but it’s a planned feature), so in this article we see how to come up with a workaround to make LiveView playing together with a JavaScript library like Select2.

We see how to take advantage of ​phx:update​ events, which LiveView dispatches every time it updates the DOM. Then, we see how to send events to the server using ​liveSocket.

In this episode of ElixirMix, we talk with Brujo Benavides We also discuss dialyzer, understanding common errors, the company Inaka and the community that grew in its place, and upcoming events like Spawnfest and Elixir Conf Latin America.
