#validateBatch method

Validator.validateBatch(schema, dataArray) Use the same compiled Schema to validate multiple pieces of data.

#method signature

validator.validateBatch(schema, dataArray)

#return value

Returns an array, each item is consistent with the return structure of a single validator.validate():

• valid - ​​passed or not
• data - ​​Validated data (when passed)
• errors - ​​error list (on failure)

[
  { valid: true, data: { email: 'a@example.com' }, errors: [] },
  { valid: false, data: { email: 'bad' }, errors: [/* ... */] }
]

import { Validator, s } from 'schema-dsl/pure';
const validator = new Validator();
const schema = s({ email: 'email!' });
const results = validator.validateBatch(schema, [
  { email: 'a@example.com' },
  { email: 'bad' }
]);
console.log(results);

#Applicable scenarios

• Batch validation before importing data
• Pre-checking a large number of records under the same schema
• I hope to compile the schema only once and then reuse it for the entire batch of data.
