rawCheckAsync

Creates a raw check validation action.

const Action = v.rawCheckAsync<TInput>(action);

Generics

• TInput extends any

Parameters

• action (context: Context<TInput>) => MaybePromise<void>

Explanation

With rawCheckAsync you can freely validate the input with a custom action and add issues if necessary.

Returns

• Action RawCheckActionAsync<TInput>

Examples

The following examples show how rawCheckAsync can be used.

Add users schema

Object schema that ensures that only users not already in the group are included.

This rawCheckAsync validation action adds an issue for any invalid username and forwards it via path to the appropriate nested field.

import { isAlreadyInGroup } from '~/api';

const AddUsersSchema = v.pipeAsync(
  v.object({
    groupId: v.pipe(v.string(), v.uuid()),
    usernames: v.array(v.pipe(v.string(), v.nonEmpty())),
  }),
  v.rawCheckAsync(async ({ dataset, addIssue }) => {
    if (dataset.typed) {
      await Promise.all(
        dataset.value.usernames.map(async (username, index) => {
          if (await isAlreadyInGroup(username, dataset.value.groupId)) {
            addIssue({
              received: username,
              message: 'The user is already in the group.',
              path: [
                {
                  type: 'object',
                  origin: 'value',
                  input: dataset.value,
                  key: 'usernames',
                  value: dataset.value.usernames,
                },
                {
                  type: 'array',
                  origin: 'value',
                  input: dataset.value.usernames,
                  key: index,
                  value: username,
                },
              ],
            });
          }
        })
      );
    }
  })
);
