How To Return All Validation Errors

[MikeO89]

Example schema:

{
"$schema": "https://json-schema.org/draft/2020-12/schema",
"title": "Example Schema.",
"description": "Some example schema.",
"type": "object",
"properties": {
"firstName": {
"$ref": "#/$defs/name"
},
"surname": {
"$ref": "#/$defs/name"
},
"age": {
"type": "number",
"minimum": 0
}
},
"required": [
"firstName",
"surname",
"age"
],
"$defs": {
"name": {
"type": "string",
"minLength": 3
}
},
"additionalProperties": false
}

Example Node JS Code:

const person = {
"firstName": "",
"age": "25"
};
const isValidResult = await validate(url);
const result = isValidResult (person, VERBOSE);

The following 3 errors exist:

• Message: String '' is less than minimum length of 3.
  Schema path: #/$defs/name/minLength

• Message: Invalid type. Expected Number but got String.
  Schema path: #/properties/age/type

• Message: Required properties are missing from object: surname.
  Schema path: #/required

result.errors contains 1/3 of the errors and is not reporting 3/3 errors (all three). How would I achieve this, if possible?

This implementation doesn't support returning all errors. It returns immediately when the first error is found.

Is returning all errors something you have on your roadmap? I’d like to migrate from avj to this library but the lack of an allErrors flag is a blocker for me

Yes, in fact I was thinking about this just the other day. I can't say when it's likely to happen, but it is something I'm thinking about.
