Validations (optional)

You can enable a request validations middleware based on your custom definitions.

Call validate function inside your custom endpoint registration.

Pass your router, services, schema and a list (optional) of endpoints you want to validate.

Example below:

const { validate } = require('directus-extension-api-docs');

const id = 'my-custom-path';

module.exports = {
    id,
    handler: async function registerEndpoint(router, { services, getSchema }) {

        const schema = await getSchema();
        await validate(router, services, schema); // Enable validator

        router.post('/my-endpoint', async (req, res, next) => {
            ...
        });
    },
};
