Init the middleware with the required openapi formats

[kobik]

Currently in order to support openapi formats which are part of the standard and are not supported by ajv, we required to pass them explicitly when calling init function. otherwise, we'll get an exception when a definitions file with these formats is passed to the middleware.

My proposal is to init the middleware with these formats by default.

Can you provide a list of these formats?

Formats for type number (source) (some of these are mentioned in the README):

• float
• double
• int32
• int64

Formats for type string (source):

• date
• date-time
• password
• byte
• binary

However, format is an open value, so you can use any formats, even not those defined by the OpenAPI Specification, such as:

• email
• uuid
• uri
• hostname
• ipv4
• ipv6

I've prepared a fix in PayU/api-schema-builder#37 which awaits for review, to finally handle this issue.
