Poison is a popular library in the Elixir programming language for handling JSON parsing and encoding. It provides a flexible and efficient solution for working with JSON data structures.

Installation[edit]

To install Poison, you can add it as a dependency to your project's `mix.exs` file:

``` defp deps do

 [
   {:poison, "~> 4.0"}
 ]

end ```

After adding the dependency, you can install it by running:

``` $ mix deps.get ```

Features[edit]

Poison offers a range of features to simplify JSON handling in Elixir:

  • Fast and efficient JSON parsing and encoding.
  • Flexible configuration options for controlling various aspects of the JSON handling process.
  • Error handling mechanisms to conveniently handle and manage errors during the JSON parsing process.
  • Support for working with custom data types and custom encoders and decoders.
  • Ability to handle both simple JSON structures and complex nested objects.
  • Integration with other popular Elixir libraries and frameworks.

Usage[edit]

To use Poison in your Elixir application, you need to require it and start working with JSON data. The basic usage involves parsing and encoding JSON:

```elixir

  1. Parsing JSON

json = ~s({"name": "John", "age": 30}) {:ok, data} = Poison.decode(json) IO.inspect(data) #=> %{"name" => "John", "age" => 30}

  1. Encoding JSON

data = %{name: "John", age: 30} {:ok, json} = Poison.encode(data) IO.puts(json) #=> {"name":"John","age":30} ```

For more detailed usage examples, refer to the Poison documentation.
