Components API Components work very similarly to how they worked before, but with a few differences. To define a component, you can create a file in your configured temple components directory, which defaults to `lib/components`. You would probably want ot change that to be `lib/my_app_web/components` if you are building a phoenix app. This file should be of the `.exs` extension, and contain any temple compatible code. You can then use this component in any other temple template. For example, if I were to define a `flex` component, I would create a file called `lib/my_app_web/components/flex.exs`, with the following contents. ```elixir div class: "flex #{@temple[:class]}", id: @id do @children end ``` And we could use the component like so ```elixir flex class: "justify-between items-center", id: "arnold" do div do: "Hi" div do: "I'm" div do: "Arnold" div do: "Schwarzenegger" end ``` We've demonstated several features to components in this example. We can pass assigns to our component, and access them just like we would in a normal phoenix template. If they don't match up with any assigns we passed to our component, they will be rendered as-is, and will become a normal Phoenix assign. You can also access a special `@temple` assign. This allows you do optionally pass an assign, and not have the `@my_assign` pass through. If you didn't pass it to your component, it will evaluate to nil. The block passed to your component can be accessed as `@children`. This allows your components to wrap a body of markup from the call site. In order for components to trigger a recompile when they are changed, you can call `use Temple.Recompiler` in your `lib/my_app_web.ex` file, in the `view`, `live_view`, and `live_component` functions ```elixir def view do quote do # ... use Temple.Recompiler # ... end end ``` 2020-07-16 02:11:35 +00:00			`div class: @class do`
