Specs

mount(
  unsigned_params() | :not_mounted_at_router,
  session :: map(),
  socket :: Phoenix.LiveView.Socket.t()
) ::
  {:ok, Phoenix.LiveView.Socket.t()}
  | {:ok, Phoenix.LiveView.Socket.t(), keyword()}

The LiveView entry-point.

For each LiveView in the root of a template, mount/3 is invoked twice: once to do the initial page load and again to establish the live socket.

It expects three arguments:

  • params - a map of string keys which contain public information that can be set by the user. The map contains the query params as well as any router path parameter. If the LiveView was not mounted at the router, this argument is the atom :not_mounted_at_router
  • session - the connection session
  • socket - the LiveView socket

It must return either {:ok, socket} or {:ok, socket, options}, where options is one of:

  • :temporary_assigns - a keyword list of assigns that are temporary and must be reset to their value after every render. Note that once the value is reset, it won't be re-rendered again until it is explicitly assigned

  • :layout - the optional layout to be used by the LiveView
