PlugLocaleRootRedirect
=================
[](https://travis-ci.org/remiprev/plug_locale_root_redirect)
[](https://hex.pm/packages/plug_locale_root_redirect)
`PlugLocaleRootRedirect` ensures that all requests to the root path (`/`) are
redirected to the best locale path, from a list of supported locales
Installation
------------
Add `plug_locale_root_redirect` to the `deps` function in your project's `mix.exs` file:
```elixir
defp deps do
[
…,
{:plug_locale_root_redirect, "~> 0.1"}
]
end
```
Then run `mix do deps.get, deps.compile` inside your project's directory.
Usage
-----
`PlugLocaleRootRedirect` can be used just as any other plugs. Add
`PlugLocaleRootRedirect` before all of the other plugs you want to happen after
successful redirection to your locale path.
```elixir
defmodule Endpoint do
plug PlugLocaleRootRedirect, locales: ~w(en fr)
end
```
The result:
```bash
$ curl -sI "http://localhost:4000" -H "Accept-Language: fr;q=1, en;q=0.8" | grep "302\|Location"
HTTP/1.1 302 Found
Location: /fr
$ curl -sI "http://localhost:4000" -H "Accept-Language: fr;q=0.4, en;q=0.8" | grep "302\|Location"
HTTP/1.1 302 Found
Location: /en
$ curl -sI "http://localhost:4000" -H "Accept-Language: es;q=1, ru;q=0.5" | grep "302\|Location"
HTTP/1.1 302 Found
Location: /en
$ curl -sI "http://localhost:4000" | grep "302\|Location"
HTTP/1.1 302 Found
Location: /en
```
If a request is made to `/`, it will be redirected to `/en` or `/fr`, depending
on the request locale preference. If the request has no preference between
supported locales, it will be redirected to the first locale, `/en` in this
case.
