RabbitMQ definitions.json file validator

Script to do basic validation on definitions.json file for RabbitMQ for GitOps:

• validates the shape of the json,
• asserts all the names only to contain ASCII printable characters: a-z0-9:_./\-*#,
• when second path argument is provided, also checks usage against a fixed list.

usage.json

usage.json should contain json array of following objects:

• { vhost: string, queue: string } if the entry represents interacting with queue directly or
• { vhost: string, exchange: string, queue: string } if the entry represents interacting with queue through an exchange.

Such statistics can be fetch from Prometheus API for example.

npx rabbit-validator <path/definitions.json> [<path/usage.json>]

npm i rabbit-validator # install locally

npx rabbit-validator <path/definitions.json> [<path/usage.json>]
# or to force npx offline:
npx --offline rabbit-validator <path/definitions.json> [<path/usage.json>]

# --offline is not required if previously installed, but errors if
# it isn't instead of downloading the package
