Can I set exact value in a JSON Schema?

Question

Solution 1

You can:

{ "enum": [123] }

or

{ "const": 123 }

const is now part of draft-06 of JSON schema specification (it is supported by Ajv and some other validators).

Solution 2

Already mentioned but the 2 options I know are:

{ "enum": [123] }

and

{ "const": 123 }

My source was: https://json-schema.org/understanding-json-schema/reference/generic.html

Keep up the good work!
