Aerials

Gem generates constant JSON. As consequence, you can MD5 it and this will remain the same.

Add this line to your application's Gemfile:

gem 'aerials'

And then execute:

$ bundle

Or install it yourself as:

$ gem install aerials

• No extra spaces
• Always use double quotes for keys and array/hash values ("")
• Always add slashes to double quotes (replace " with ")
• Always use UTF8 (TODO)
• Always sort by keys on each level (arrays should be sorted by values)
• Always sort as strings

struct = {
    array: [2, '1'],
    hash: {
        'a' => '1'
    },
    a: 2,
}
Aerials.create_json struct

# will eq
# '{"a":"2","array":["1","2"],"hash":{"a":"1"}}'

You can exclude fields:

Aerials.create_json(struct, exclude: [:controller])

Or use default Rails exclusion:

Aerials.create_json_rails struct
# equals to:
Aerials.create_json struct, exclude: [:action, :controller, :key]
