This is a library helps generate meta tags for a website.
### Default Usage
From a struct like this:
```elixir
%{
title: "Phoenix Title",
description: "Phoenix Descriptions",
url: "https://phoenix.meta.tags",
image: "https://phoenix.meta.tags/logo.png"
}
```
will become:
```html
# Default tags
Phoenix Title
#Open Graph tags
#Twitter tags
```
### Advanced Usage
Other key value of tags map will be rendered individually by key. Nested map will be rendered by *flat-representation* of keys. For example:
```elixir
map = %{
title: "Phoenix Title",
description: "Phoenix Descriptions",
url: "https://phoenix.meta.tags",
image: "https://phoenix.meta.tags/logo.png",
fb: %{
name: "facebook",
size: %{
width: 100,
height: 200,
position: %{
x: 10,
y: 15
}
}
}
}
```
In addition to default tags like above example, the rendered tags will have more:
```html
```
Instead of a nested map, you can also use a string-key map, this also delivers the same result:
```elixir
map = %{
"title" => "PhoenixTags",
"fb:name" => "facebook",
"fb:size:width" => 100,
"fb:size:height" => 200,
"fb:size:position:x" => 10,
"fb:size:position:y" => 15
}
```
### Tag Value Override
In default rendering, the **og:title** tag will get value from **title**. If you re-define **og:title** value, the new value will be override the default **title** value. For example:
```elixir
map = %{
title: "Phoenix Title",
og: %{
title: "Override"
}
}
```
Will have output:
```html
Phoenix Title
```
## Installation
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, ">= 0.1.9"}
]
end
```
In your Web Module add this:
```elixir
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 **\** tag of `app.html.eex`:
```elixir
<%= render_tags_all(assigns[:meta_tags] || %{})%> # Add this
```
## Usage
Wherever you want to render meta tags, jut put it before render your view:
```elixir
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:
```elixir
@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. This config will be merge with runtime tags before rendering.
```elixir
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",
"og:text": "Hello Open Graph",
fb: %{
name: "facebook",
size: %{
width: 100,
height: 200,
position: %{
x: 10,
y: 15
}
}
}
```
