## PhoenixMetaTags
This is a library helps generate meta tags for a website.
From a struct like this:
```
%{
title: "Phoenix Title",
description: "Phoenix Descriptions",
url: "https://phoenix.meta.tags",
image: "https://phoenix.meta.tags/logo.png"
}
```
will become:
```
# Default tags
<title>Phoenix Title</title>
<meta content="Phoenix Title" name="title">
<meta content="Phoenix Descriptions" name="description">
#Open Graph tags
<meta content="website" property="og:type">
<meta content="https://phoenix.meta.tags" property="og:url">
<meta content="Phoenix Title" property="og:title">
<meta content="Phoenix Descriptions" property="og:description">
<meta content="https://phoenix.meta.tags/logo.png" property="og:image">
#Twitter tags
<meta content="summary_large_image" property="twitter:card">
<meta content="https://phoenix.meta.tags" property="twitter:url">
<meta content="Phoenix Title" property="twitter:title">
<meta content="Phoenix Descriptions" property="twitter:description">
<meta content="https://phoenix.meta.tags/logo.png" property="twitter:image">
```
## Installation
If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `phoenix_meta_tags` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:phoenix_meta_tags, "~> 0.1.0"}
]
end
```
In your Web Module add this:
```
def view do
quote do
...
use PhoenixMetaTags.TagView # Add this
end
end
def controller do
quote do
...
use PhoenixMetaTags.TagController # Add this
end
end
```
Also put this render function inside your **\<head\>** tag of app.html.eex:
```
<head>
<%= render_tags_all(assigns[:meta_tags] || %{})%>
</head>
```
## Usage
Wherever you want to render meta tags, jut put it before render your view:
```
conn
|> put_meta_tags(
%{
title: "Phoenix Title",
description: "Phoenix Descriptions",
url: "https://phoenix.meta.tags",
image: "https://phoenix.meta.tags/logo.png"
})
|>render("index.html")
```
Or, use it as a plug:
```
@meta %{
title: "Phoenix Title",
description: "Phoenix Descriptions",
url: "https://phoenix.meta.tags",
image: "https://phoenix.meta.tags/logo.png"
}
plug :put_meta_tags, @meta
```
### Default value
You can put the default value for meta tags in your config file:
```
config :phoenix_meta_tags,
title: "Phoenix Title Default",
description: "Phoenix Descriptions Default",
url: "https://phoenix.meta.tags.default",
image: "https://phoenix.meta.tags.default/logo.png"
```
If a controller has no meta tags, this default value will be used.
