## About
A simple Mix task that generates Phoenix Components from Font Awesome SVG files. Documentation is available
[here](https://hexdocs.pm/phx_fontawesome).
## Installation
This package is [available in Hex](https://hex.pm/packages/phx_fontawesome), and can be installed
by adding `phx_fontawesome` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:phx_fontawesome, "~> 1.2"}
]
end
```
## Generate Heex components
**Step 1 - Install desired font set**
In your Phoenix project, install desired font set using `npm` or `yarn`. Please consult the Font Awesome
[documentation](https://fontawesome.com/docs/web/setup/packages) if you run into any trouble here.
```shell
$ cd assets/
$ yarn add @fortawesome/fontawesome-free
# or
$ yarn add @fortawesome/fontawesome-pro # needs a license
```
**Step 2 - Choose font set types to generate**
In your `config.exs`, you may choose which types to generate `heex` components for. Defaults to `regular` and `solid`.
```elixir
config :phx_fontawesome,
types: ["regular", "solid"]
```
Additionally, you may override the default location for generated files (`deps/phx_fontawesome/lib`).
```elixir
config :phx_fontawesome,
dest_path: "./lib/phx_fontawesome" # includes generated files in your projects lib/ directory
```
**Step 3 - Generate component files**
From your project root, run `mix phx_fontawesome.generate` to create components files. Generated components will be available in your
`deps/phx_fontawesome/lib/phx_fontawesome` directory (unless using a custom path).
```shell
$ mix phx_fontawesome.generate
[info] Successfully wrote /my_project/deps/phx_fontawesome/lib/phx_fontawesome/fontawesome_free/regular.ex (containing 162 SVG components).
[info] Successfully wrote /my_project/deps/phx_fontawesome/lib/phx_fontawesome/fontawesome_free/solid.ex (containing 1385 SVG components).
$ mix deps.compile phx_fontawesome
==> phx_fontawesome
Compiling 3 files (.ex)
...
```
**Remember to run `mix deps.compile phx_fontawesome` after generating files to compile the components!**
## Usage
If using the default `dest_path`, you need to add `deps/phx_fontawesome/lib/phx_fontawesome` to your `elixirc_paths`.
```elixir
# mix.exs
defmodule MyProject.MixProject do
# snip...
defp elixirc_paths(_env) do
[
"lib",
"test/support",
"deps/phx_fontawesome/lib/phx_fontawesome" # add this line
]
end
end
```
Once generated, the `heex` components are available to your project, and can be used as a regular `Phoenix.Component`.
Icon name can be the function or passed in as a type.
```html
<!-- Use the PhxFontawesome component and pass all required props -->
<PhxFontawesome.render icon="angle_up" set="free" type="regular" />
<!-- Or use the generated components directly -->
<PhxFontawesome.Free.Solid.angle_up />
<PhxFontawesome.Free.Regular.render icon="angle_up" />
<!-- append custom classes -->
<PhxFontawesome.Free.Solid.angle_up class="my-custom-class" />
<!-- remove default classes by prefixing wiht "!" -->
<PhxFontawesome.Free.Solid.angle_up class="!fa-angle-up" />
<!-- pass extra properties -->
<PhxFontawesome.Free.Solid.angle_up title="Font Awesome angle-up icon" />
```
If you would like to apply the default styling for SVG elements, simply include the Font Awesome CSS in your `app.css` file.
```css
@import "@fortawesome/fontawesome-free/css/all.css";
@import "@fortawesome/fontawesome-free/css/svg-with-js.css";
```
Keep in mind that if you're using the non-free version of Font Awesome, make sure that you don't publish the
generated components as that would be a licensing breach.
