<!-- MDOC !-->

`Doumi.URI.Query` is a helper library that supports encoding complicated query of URI.

**도우미(Doumi)** means "helper" in Korean.

## Usage

It's common to send nested maps or lists via query string even though it is not standardized.

`URI.encode_query/2` does not support nested maps or lists and can't be customized to handle that.

`Doumi.URI.Query` supports encoding maps or lists to query string. (only PHP-style now)

```elixir
iex> query = %{"foo" => %{"bar" => 1, "baz" => 2}}
iex> Doumi.URI.Query.encode(query)
"foo%5Bbar%5D=1&foo%5Bbaz%5D=2" # foo[bar]=1&foo[baz]=2

iex> query = %{"foo" => [1, 2, 3]}
iex> Doumi.URI.Query.encode(query)
"foo%5B%5D=1&foo%5B%5D=2&foo%5B%5D=3" # foo[]=1&foo[]=2&foo[]=3
```

## Installation

If [available in Hex](https://hexdocs.pm/doumi_uri_query/), the package can be installed
by adding `doumi_phoenix_svg` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:doumi_uri_query, "~> 0.1.0"}
  ]
end
```
