jason elixir

To work with JSON in Elixir, you can use the Jason library, which is a fast JSON parser and encoder. It provides functions to parse JSON strings into Elixir data structures and encode Elixir data structures into JSON strings.

To use Jason, you need to add it as a dependency in your mix.exs file:

defp deps do
    {:jason, "~> 1.2"}

After adding the dependency, you can install the library by running mix deps.get.

Once you have Jason installed, you can use it to parse JSON strings and encode Elixir data structures into JSON.

Here's an example of parsing a JSON string:

json_string = ~s({"name": "John", "age": 30})
parsed_data = Jason.decode!(json_string)

This will output the parsed JSON as an Elixir map:

%{"name" => "John", "age" => 30}

You can also encode Elixir data structures into JSON:

data = %{"name" => "John", "age" => 30}
json_string = Jason.encode!(data)

This will output the encoded JSON string:


These are just basic examples, and Jason provides many more functions for working with JSON. You can refer to the Jason documentation for more information on advanced usage and customization options.
