## 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, "~> 0.3.0"},
  ]
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
      }
    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.
