## 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.
