Performing asynchronous work is common in LiveViews and LiveComponents. Render/1 function altogether and put the template code at For example, if the file above is placedĪt lib/my_app_web/live/demo_live.ex, you can also remove the defmodule MyAppWeb.DemoLive do use Phoenix.LiveView def render ( assigns ) do ~H"""įor larger templates, you can place them in a file in the same directoryĪnd same name as the LiveView. One is by explicitly defining a render function, which receives assignsĪnd returns a HEEx template defined with the ~H sigil. There are two possible ways of rendering content in a LiveView. LiveView also allows attaching hooks to specific life-cycle stages with Reconnects to the server, calling mount/3 and handle_params/3 again. Is encountered, or the client connection drops, the client gracefully If at any point during the stateful life-cycle a crash The result of render/1 to the client and continues on for the duration Is spawned on the server, runs handle_params/3 again and then pushes However in the connected client case, a LiveView process The first rendering, mount/3, is invoked with params, session,Īnd socket state. To the browser, and receive client events via phx- bindings. To the server where stateful views are spawned to push rendered updates Is invoked and the HTML is sent as a regular HTML response to theĪfter rendering the static page, LiveView connects from the client Is invoked so uri and query params are handled. The mount/3 callback wires up socketĪssigns necessary for rendering the view. The session always contains private data setīy the application itself. With the current params, the current session and the LiveView socket.Īs in a regular request, params contains public data that can be When LiveView is first rendered, the mount/3 callback is invoked You begin by rendering a LiveView typically from your router. Of a token or cookie and rebuilding the state on the server to service HTTP pattern of sending the connection state to the client in the form This is different from the common stateless Socket assigns are stateful values kept on the server side in Guaranteeing a regular HTML page even if JavaScript is disabled.Īny time a stateful view changes or updates its socket assigns, it isĪutomatically re-rendered and the updates are pushed to the client. This module provides advanced documentation and featuresĪ LiveView begins as a regular HTTP request and HTML response,Īnd then upgrades to a stateful view on client connect, Its state, and renders updates to a page as diffs.
