    Study Notes

    API Route Functions and Consumption Summary

    • The provided code includes functions for creating, updating, and deleting activities in an API route.
    • The functions first check if the user is authenticated and return appropriate status codes if not.
    • The request body is parsed and validated using the zod library and specific schemas.
    • If the request body is valid, a new activity is created in the database and its ID is returned as a JSON string.
    • The z.ZodError error is thrown if the request body does not match the schema, containing validation errors in the issues property.
    • The PATCH and DELETE functions also follow a similar structure, including authentication checks and request context validation.
    • The PATCH function updates the activity in the database based on the request body, while the DELETE function removes the activity.
    • Both functions return appropriate status codes based on the outcome of the operations.
    • API routes are consumed in a server component for fetching activities, using the getUserActivities function from /lib/api/activities.ts.
    • The getUserActivities function accesses the database directly and fetches activities for the selected user using a raw SQL query.
    • The results are returned as an array of UserActivities objects.
    • The provided code demonstrates server-side rendering and direct database access for fetching activities, as well as the structure and validation of API route functions.
