## About 🌺

Petal stands for:

* [Phoenix](https://www.phoenixframework.org/)
* [Elixir](https://elixir-lang.org/)
* [Tailwind CSS](https://tailwindcss.com/)
* [Alpine JS](https://alpinejs.dev/) (optional)
* [Live View (HEEX)](https://hexdocs.pm/phoenix_live_view/Phoenix.LiveView.html)

Petal is a set of HEEX components that makes it easy for Phoenix developers to start building beautiful web apps.

Some components like [Dropdowns](#dropdowns) require Javascript to work. We default to Alpine JS (17kb) but you can choose to use `Phoenix.LiveView.JS` as an alternative (though this will only work in live environments like live views or live components).

## Install

For Petal to work you simply need Tailwind CSS and Alpine JS installed along with with some Tailwind configuration.

### Existing projects

1 - Follow [this guide](https://sergiotapia.com/phoenix-160-liveview-esbuild-tailwind-jit-alpinejs-a-brief-tutorial) to install Tailwind and Alpine.

2 - Add Petal to your deps:

`mix.exs`

```elixir
defp deps do
  [
    {:petal_components, "~> 0.5.0"},
  ]
end
```

3 - Modify your `tailwind.config.js` file to include these settings:

```js
const colors = require("tailwindcss/colors");

module.exports = {
  mode: "jit",
  purge: [
    "../lib/*_web/**/*.*ex",
    "./js/**/*.js",

    // We need to include the Petal dependency so the classes get picked up by JIT.
    "../deps/petal_components/**/*.*ex"
  ],
  darkMode: false,
  theme: {
    extend: {

      // Set these to your brand colors
      colors: {
        primary: colors.blue,
        secondary: colors.pink,
      },
    },
  },
  plugins: [require("@tailwindcss/forms")],
};
```

4 - Alias the components in your `<your_project>_web.ex` file

```elixir
defmodule YourProjectWeb
  ...

  defp view_helpers do
    quote do
      ...

      use PetalComponents
    end
  end
```

This will import the functions so you can go `<.button />` in your templates / live views.

If the function names clash with yours (eg. you already have a `.button` function) you can opt to alias the modules instead:

```elixir
defmodule YourProjectWeb
  ...

  defp view_helpers do
    quote do
      ...

      alias PetalComponents.{
        Heroicons,
        Alert,
        Badge,
        Button,
        Container,
        Dropdown,
        Form,
        Loading,
        Typography,
        Breadcrumb,
        Avatar,
        Progress
      }
    end
  end
```

### New projects

We recommend using [Petal boilerplate](https://github.com/petalframework/petal_boilerplate), which is a fresh Phoenix install with Tailwind + Alpine installed. It comes with a project renaming script so you can still rename your project to whatever you like.

### Dropdowns

Dropdowns require Javascript. You can choose whether to use Alpine JS or the `Phoenix.LiveView.JS` module.

Note that the `Phoenix.LiveView.JS` option only works in live components. For dead components you must use Alpine JS.

```elixir
<.dropdown label="Dropdown" js_lib="alpine_js|live_view_js" placement="left|right">
  <.dropdown_menu_item>
    <Heroicons.Outline.home class="w-5 h-5 text-gray-500" />
    Button item with icon
  </.dropdown_menu_item>
  <.dropdown_menu_item link_type="button" label="a item" />
  <.dropdown_menu_item link_type="a" to="/" label="a item" />
  <.dropdown_menu_item link_type="live_patch" to="/" label="Live Patch item" />
  <.dropdown_menu_item link_type="live_redirect" to="/" label="Live Redirect item" />
</.dropdown>
```

### Loading indicators
```elixir
<.spinner show={false} />
<.spinner show={true} size="sm" />
<.spinner show={true} size="md" class="text-green-500" />
<.spinner show={true} size="lg" class="text-red-500" />
```

### Breadcrumbs

#### Slash
```elixir
<.breadcrumbs links={[
  %{ label: "Link 1", to: "#" },
  %{ label: "Link 2", to: "#" },
  %{ label: "Link 3", to: "#" }
]}/>
```

#### Chevron
```elixir
<.breadcrumbs separator="chevron" links={[
  %{ label: "Link 1", to: "#" },
  %{ label: "Link 2", to: "#", link_type: "live_patch" },
  %{ label: "Link 3", to: "#", link_type: "live_redirect" },
]}/>
```

### Breadcrumbs

#### Basic Avatars
```elixir
<.avatar size="xs | sm | md | lg | xl " src="https://res.cloudinary.com/wickedsites/image/upload/v1604268092/unnamed_sagz0l.jpg" />
```

#### Avatars with placeholder icon

```

### Progress

#### Progress bar
```elixir
<.progress color="primary | secondary | info | success | warning | danger" value={30} max={100} class="max-w-xl" />
```

##### Sizes
