Async custom validator supports

const schema = {
    // Turn on async mode for this schema
    $$async: true,
    name: {
        type: "string",
        min: 4,
        max: 25,
        custom: async (v) => {
            await new Promise(resolve => setTimeout(resolve, 1000));
            return v.toUpperCase();
        }
    },

    username: {
        type: "custom",
        custom: async (v) => {
            // E.g. checking in the DB that whether is unique.
            await new Promise(resolve => setTimeout(resolve, 1000));
            return v.trim();
        }
    },
}

The compiled check function has an async property to detect this mode. If true it returns a Promise.

const check = v.compile(schema);
console.log("Is async?", check.async);

Meta-information for custom validators

You can pass any extra meta information for the custom validators which is available via context.meta.

const schema = {
    name: { type: "string", custom: (value, errors, schema, name, parent, context) => {
        // Access to the meta
        return context.meta.a;
    } },
};
const check = v.compile(schema);

const res = check(obj, {
    // Passes meta information
    meta: { a: "from-meta" }
});

Changes

• support default and optional in tuples and arrays #226
• fix that this points to the Validator instance in custom functions #231
