0.18.0 (2022-09-20)

LiveView v0.18 includes a major new feature in the form of declarative assigns with new attr and slot APIs for specifying which attributes a function component supports, the type, and default values. Attributes and slots are compile-time verified and emit warnings (requires Elixir v1.14.0+).

v0.18 includes a number of new function components which replace their EEx expression counterparts <%= ... %>. For example, live_redirect, live_patch, and Phoenix.HTML's link have been replaced by a unified Phoenix.Component.link/1 function component:

<.link href="https://myapp.com">my app</.link>
<.link navigate={@path}>remount</.link>
<.link patch={@path}>patch</.link>

Those new components live in the Phoenix.Component module. Phoenix.LiveView.Helpers itself has been soft deprecated and all relevant functionality has been migrated. You must import Phoenix.Component where you previously imported Phoenix.LiveView.Helpers when upgrading. You may also need to import Phoenix.Component where you also imported Phoenix.LiveView and some of its functions have been moved to Phoenix.Component.

Additionally, the special let attribute on function components have been deprecated by a :let usage.

Breaking Changes

`on_mount` changes

The hook API introduced in LiveView 0.16 has been improved based on feedback. LiveView 0.17 removes the custom module-function callbacks for the Phoenix.LiveView.on_mount/1 macro and the :on_mount option for Phoenix.LiveView.Router.live_session/3 in favor of supporting a custom argument. For clarity, the module function to be invoked during the mount lifecycle stage will always be named on_mount/4.

For example, if you had invoked on_mount/1 like so:

on_mount MyAppWeb.MyHook
on_mount {MyAppWeb.MyHook, :assign_current_user}

and defined your callbacks as:

# my_hook.ex

def mount(_params, _session, _socket) do
end

def assign_current_user(_params, _session, _socket) do
end

Change the callback to:

# my_hook.ex

def on_mount(:default, _params, _session, _socket) do
end

def on_mount(:assign_current_user, _params, _session, _socket) do
end

When given only a module name, the first argument to on_mount/4 will be the atom :default.

LEEx templates in stateful LiveComponents

Stateful LiveComponents (where an :id is given) must now return HEEx templates (~H sigil or .heex extension). LEEx templates (~L sigil or .leex extension) are no longer supported. This addresses bugs and allows stateful components to be rendered more efficiently client-side.

`phx-disconnected` class has been replaced with `phx-loading`

Due to a bug in the newly released Safari 15, the previously used .phx-disconnected class has been replaced by a new .phx-loading class. The reason for the change is phx.new included a .phx-disconnected rule in the generated app.css which triggers the Safari bug. Renaming the class avoids applying the erroneous rule for existing applications. Folks can upgrade by simply renaming their .phx-disconnected rules to .phx-loading.

`phx-capture-click` has been deprecated in favor of `phx-click-away`

The new phx-click-away binding replaces phx-capture-click and is much more versatile because it can detect "click focus" being lost on containers.

Removal of previously deprecated functionality

Some functionality that was previously deprecated has been removed:

Implicit assigns in live_component do-blocks is no longer supported
Passing a @socket to live_component will now raise if possible

security-considerations-upgrading-from-0-15
Security Considerations Upgrading from 0.15

LiveView v0.16 optimizes live redirects by supporting navigation purely over the existing WebSocket connection. This is accomplished by the new live_session/3 feature of Phoenix.LiveView.Router. The security guide has always stressed the following:

... As we have seen, LiveView begins its life-cycle as a regular HTTP request. Then a stateful connection is established. Both the HTTP request and the stateful connection receives the client data via parameters and session. This means that any session validation must happen both in the HTTP request (plug pipeline) and the stateful connection (LiveView mount) ...

These guidelines continue to be valid, but it is now essential that the stateful connection enforces authentication and session validation within the LiveView mount lifecycle because a live_redirect from the client will not go through the plug pipeline as a hard-refresh or initial HTTP render would. This means authentication, authorization, etc that may be done in the Plug.Conn pipeline must also be performed within the LiveView mount lifecycle.

Live sessions allow you to support a shared security model by allowing live_redirects to only be issued between routes defined under the same live session name. If a client attempts to live redirect to a different live session, it will be refused and a graceful client-side redirect will trigger a regular HTTP request to the attempted URL.

See the Phoenix.LiveView.Router.live_session/3 docs for more information and example usage.

new-html-engine
New HTML Engine

LiveView v0.16 introduces HEEx (HTML + EEx) templates and the concept of function components via Phoenix.Component. The new HEEx templates validate the markup in the template while also providing smarter change tracking as well as syntax conveniences to make it easier to build composable components.

A function component is any function that receives a map of assigns and returns a ~H template:

defmodule MyComponent do
  use Phoenix.Component

  def btn(assigns) do
    ~H"""
    <button class="btn"><%= @text %></button>
    """
  end
end

This component can now be used as in your HEEx templates as:

<MyComponent.btn text="Save">

The introduction of HEEx and function components brings a series of deprecation warnings, some introduced in this release and others which will be added in the future. Note HEEx templates require Elixir v1.12+.

upgrading-and-deprecations
Upgrading and deprecations

The main deprecation in this release is that the ~L sigil and the .leex extension are now soft-deprecated. The docs have been updated to discourage them and using them will emit warnings in future releases. We recommend using the ~H sigil and the .heex extension for all future templates in your application. You should also plan to migrate the old templates accordingly using the recommendations below.

Migrating from LEEx to HEEx is relatively straightforward. There are two main differences. First of all, HEEx does not allow interpolation inside tags. So instead of:

<div id="<%= @id %>">
  ...
</div>

One should use the HEEx syntax:

<div id={@id}>
  ...
</div>

The other difference is in regards to form_for. Some templates may do the following:

~L"""
<%= f = form_for @changeset, "#" %>
  <%= input f, :foo %>
</form>
"""

However, when converted to ~H, it is not valid HTML: there is a </form> tag but its opening is hidden inside the Elixir code. On LiveView v0.16, there is a function component named form:

~H"""
<.form :let={f} for={@changeset}>
  <%= input f, :foo %>
</.form>
"""

We understand migrating all templates from ~L to ~H can be a daunting task. Therefore we plan to support ~L in LiveViews for a long time. However, we can't do the same for stateful LiveComponents, as some important client-side features and optimizations will depend on the ~H sigil. Therefore our recommendation is to replace ~L by ~H first in live components, particularly stateful live components.

Furthermore, stateless live_component (i.e. live components without an :id) will be deprecated in favor of the new function components. Our plan is to support them for a reasonable period of time, but you should avoid creating new ones in your application.

breaking-changes-1
Breaking Changes

LiveView 0.16 removes the :layout and :container options from Phoenix.LiveView.Routing.live/4 in favor of the :root_layout and :container options on Phoenix.Router.live_session/3.

For instance, if you have the following in LiveView 0.15 and prior:

live "/path", MyAppWeb.PageLive, layout: {MyAppWeb.LayoutView, "custom_layout.html"}

Change it to:

live_session :session_name, root_layout: {MyAppWeb.LayoutView, "custom_layout.html"} do
  live "/path", MyAppWeb.PageLive
end

On the client, the phoenix_live_view package no longer provides a default export for LiveSocket.

If you have the following in your JavaScript entrypoint (typically located at assets/js/app.js):

import LiveSocket from "phoenix_live_view"

Change it to:

import { LiveSocket } from "phoenix_live_view"

Additionally on the client, the root LiveView element no longer exposes the LiveView module name, therefore the phx-view attribute is never set. Similarly, the viewName property of client hooks has been removed.

Codebases calling a custom function component/3 should rename it or specify its module to avoid a conflict, as LiveView introduces a macro with that name and it is special cased by the underlying engine.

No longer send event metadata by default. Metadata is now opt-in and user defined at the LiveSocket level. To maintain backwards compatibility with pre-0.13 behaviour, you can provide the following metadata option:

  let liveSocket = new LiveSocket("/live", Socket, {
    params: {_csrf_token: csrfToken},
    metadata: {
      click: (e, el) => {
        return {

0.12.0 (2020-04-16)

This version of LiveView comes with an overhaul of the testing module, more closely integrating your LiveView template with your LiveView events. For example, in previous versions, you could write this test:

  render_click(live_view, "increment_by", %{by: 1})

However, there is no guarantee that there is any element on the page with a phx-click="increment" attribute and phx-value-by set to 1. With LiveView 0.12.0, you can now write:

  live_view
  |> element("#term .buttons a", "Increment")
  |> render_click()

The new implementation will check there is a button at #term .buttons a, with "Increment" as text, validate that it has a phx-click attribute and automatically submit to it with all relevant phx-value entries. This brings us closer to integration/acceptance test frameworks without any of the overhead and complexities of running a headless browser.

phx-error-for has been removed in favor of phx-feedback-for. phx-feedback-for will set a phx-no-feedback class whenever feedback has to be hidden

Phoenix.LiveViewTest.assert_redirect/3 no longer matches on the patch redirects, use assert_patch/3 instead
Phoenix.LiveViewTest.assert_remove/3 has been removed. If the LiveView crashes, it will cause the test to crash too
Passing a path with DOM IDs to render_* test functions is deprecated. Furthermore, they now require a phx-target="<%= @id %>" on the given DOM ID:
```
<div id="component-id" phx-target="component-id">
  ...
</div>
```
```
html = render_submit([view, "#component-id"], event, value)
```
In any case, this API is deprecated and you should migrate to the new element based API.

render_event/render_click and friends now expect a DOM ID selector to be given when working with components. For example, instead of render_click([live, "user-13"]), you should write render_click([live, "#user-13"]), mirroring the phx-target API.
Accessing the socket assigns directly @socket.assigns[...] in a template will now raise the exception Phoenix.LiveView.Socket.AssignsNotInSocket. The socket assigns are available directly inside the template as LiveEEx assigns, such as @foo and @bar. Any assign access should be done using the assigns in the template where proper change tracking takes place.

LiveView now makes the connection session automatically available in LiveViews. However, to do so, you need to configure your endpoint accordingly, otherwise LiveView will fail to connect.

The steps are:

Find plug Plug.Session, ... in your endpoint.ex and move the options ... to a module attribute:
```
 @session_options [
   ...
 ]
```
Change the plug Plug.Session to use said attribute:
```
 plug Plug.Session, @session_options
```

Also pass the @session_options to your LiveView socket:

 socket "/live", Phoenix.LiveView.Socket,
   websocket: [connect_info: [session: @session_options]]

You should define the CSRF meta tag inside <head> in your layout, before app.js is included:

 <meta name="csrf-token" content={Plug.CSRFProtection.get_csrf_token()} />
 <script type="text/javascript" src="<%= Routes.static_path(@conn, "/js/app.js") %>"></script>

Then in your app.js:

 let csrfToken = document.querySelector("meta[name='csrf-token']").getAttribute("content");
 let liveSocket = new LiveSocket("/live", Socket, {params: {_csrf_token: csrfToken}});

Also note that the session from now on will have string keys. LiveView will warn if atom keys are used.
