parserAsync

Returns a function that parses an unknown input based on a schema.

const parser = v.parserAsync<TSchema, TConfig>(schema, config);

Generics

• TSchema extends BaseSchema<unknown, unknown, BaseIssue<unknown>> | BaseSchemaAsync<unknown, unknown, BaseIssue<unknown>>
• TConfig extends Config<InferIssue<TSchema>> | undefined

Parameters

• schema TSchema
• config TConfig

Returns

• parser ParserAsync<TSchema, TConfig>

Examples

The following examples show how parserAsync can be used.

import { isEmailPresent } from '~/api';

try {
  const StoredEmailSchema = v.pipeAsync(
    v.string(),
    v.email(),
    v.checkAsync(isEmailPresent, 'The email is not in the database.')
  );
  const storedEmailParser = v.parserAsync(StoredEmailSchema);
  const storedEmail = await storedEmailParser('jane@example.com');

  // Handle errors if one occurs
} catch (error) {
  console.error(error);
}
