Normalise AJV error messages
npm install ajv-error-messagesNormalise errors from ajv to a simpler format.
Takes ajv errors and returns a simpler object. Inspired by https://github.com/MauriceButler/jayschema-error-messages
v2 of ajv-error-messages has been upgraded to work with v8 of ajv
``javascript
var normalise = require('ajv-error-messages');
var SchemaValidator = require('ajv');
var schemaValidator = SchemaValidator({ allErrors: true });
var schema = {
description: 'test schema',
type: 'object',
additionalProperties: false,
required: ['foo'],
properties: {
foo: {
type: 'string',
},
},
};
var invalidData = {
foo: 2,
};
var validator = schemaValidator.compile(schema);
function validatingData(data) {
var valid = validator(data);
var normalisedErrors;
if (!valid) {
var ajvErrors = validator.errors
normalisedErrors = normalise(ajvErrors);
}
return valid || normalisedErrors;
}
console.log(JSON.stringify(validatingData(invalidData)));
`
results in
`
{
fields: {
'foo': ['Must be string']
}
}
