This is a zc.buildout recipe that programatically creates JSON files

Lets look at an example using a buildout part:

[nodeserver-env]
recipe = nti.recipes.json
output-file = /home/user/etc/nodeserver-env.json
contents-section = nodeserver-env-root

[nodeserver-env-root]
stripe-section = nodeserver-stripe
jquery-payment-section = nodeserver-jquery.payment

[nodeserver-jquery.payment]
requires =
  jquery
  stripe
  **end-list**
url = https://my.server.com/libs/jquery.payment/1.3.2/jquery.payment.min.js
definesSymbol = jQuery.payment

[nodeserver-stripe]
url = https://js.stripe.com/v2/
definesSymbol = Stripe

The output for /home/user/etc/nodeserver-env.json will be:

{
    "jquery-payment": {
                "definesSymbol": "jQuery.payment",
                "requires": [
                        "jquery",
                        "stripe"
                ],
                "url": "https://my.server.com/libs/jquery.payment/1.3.2/jquery.payment.min.js"
        },
        "stripe": {
                "definesSymbol": "Stripe",
                "url": "https://js.stripe.com/v2/"
        }
}
