Poison/HexDocs[edit]
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
- Parsing JSON
json = ~s({"name": "John", "age": 30}) {:ok, data} = Poison.decode(json) IO.inspect(data) #=> %{"name" => "John", "age" => 30}
- 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.
