React and Deno: A Practical Guide

Implement a robust logout flow in a React and Deno app by clearing cookies and JWTs, returning a success message, and protecting routes with an OAuth middleware that validates authentication.

Introduce a user service that injects a user repository, moving password filtering and data formatting from the controller to the service, while the repository handles database queries.

Explore abstract service and repository design, protected versus private access, crud methods including find and find one, create, update, and delete with super calls to extend user and url services.

Refactor the upstart service and repository to support multi-key where conditions by introducing a where interface, applying dynamic key-value searches, and simplifying the controller with email-based lookups.

Update role permissions by deleting existing permissions before inserting new ones, and adapt the service to support deletes based on conditions to ensure data integrity.

Create an image controller and enable multipart form uploads. Implement endpoints to upload and serve images from an uploads folder.

Export orders to a csv file by importing a csv writer, building headers and rows from orders and order items, and returning a downloadable attachment via a post route.

Explore using the useEffect hook with axios to fetch the authenticated user and display their name in navigation, handling authentication and sign-out in React and Deno.

Configure Axios defaults globally by setting a base URL prefix and withCredentials to true, streamlining login and endpoint calls while ensuring authenticated user retrieval.

Learn to implement paginated user data in React and Deno by adding next and prev controls, tracking page state, refetching data with useEffect on page changes, and enforcing last-page bounds.

Delete a user by clicking a delete button, confirm the action, send a delete request with the user id via Axios, and update the UI by filtering the remaining users.

Create the products page, build a products table, and implement a product model with id, title, description, image, and price, plus delete and pagination controls.

Prefill a product edit form using useEffect and axios, then update the product with a put request while using useRef to manage the image input.

Create a React profile page with two forms to update account information and password, prefill data with useEffect, and submit via redux actions to fix updates and reduce user calls.
