Microsoft Word - Node React createspace v1.3.docx : Chapter Twenty Two -Twenty Four.

Based on the structure of Beginning MERN Stack: Build and Deploy a Full Stack Movie Review App by Greg Lim, Chapters 21–24 here is the long description of Chapters 21-24: Chapter 21: Adding And Editing Reviews This chapter focuses on enabling user interaction within the frontend application. Creating a Review Component: Developing a React component to allow users to write and edit reviews for movies. Form Management: Implementing form inputs to handle user input for ratings and comments. Connecting to Backend API: Connecting the React frontend to the Express backend to send POST and PUT requests for creating or updating reviews. Handling State: Managing the state of the form to ensure that existing reviews can be edited, while new reviews can be added seamlessly. Chapter 22: Deleting A Review This chapter covers the functionality required to allow users to remove their own reviews. Deleting Functionality: Implementing the logic to send a DELETE request to the backend API. User Interface Updates: Creating a delete button within the review display component. Frontend-Backend Sync: Ensuring that after a successful deletion in the database (MongoDB), the React UI updates instantly to remove the review from the screen. Leanpub Leanpub Chapter 23: Get Next Page's Results As the application grows, listing all reviews or movies on one page becomes inefficient. This chapter introduces pagination. Implementing Pagination: Modifying the frontend to fetch data in chunks rather than all at once. "Load More" Logic: Implementing functionality to fetch the next set of results from the API when a user clicks a "Next" button. State Management: Updating the React component state to append new results to the existing list, rather than replacing it. Chapter 24: Get Next Page's Results – Search By Title And Rating This chapter extends the pagination logic to include searching and filtering. Search Functionality: Adding search inputs to the frontend to allow users to find movies based on their titles. Filter by Rating: Implementing filters to narrow down movies based on their ratings. Combined Logic: Combining the search, filter, and pagination logic to ensure that "Next Page" fetches the next results for the specifically searched or filtered query, rather than the general list. In the book Beginning MERN Stack: Build and Deploy a Full Stack MongoDB, Express, React, Node.js App by Greg Lim, Chapters 21 through 24 focus on enhancing the functionality of the Movie Reviews application, specifically handling user interactions with reviews and implementing pagination. Amazon.com Amazon.com The long descriptions for these chapters are as follows: Chapter 21: Adding and Editing Reviews This chapter guides you through creating the front-end components and logic required for users to submit new movie reviews or modify existing ones. It typically involves building a form with validation, managing local state in React to handle input changes, and making POST and PUT requests to the backend API. Chapter 22: Deleting a Review Focuses on implementing the "Delete" functionality of the CRUD cycle. You learn how to add a delete button to the review component, capture the specific review ID, and send a DELETE request to the server. It also covers updating the UI state so the review disappears immediately after being removed. Chapter 23: Get Next Page's Results Introduces pagination to improve application performance and user experience. Instead of loading every review at once, you implement logic to fetch and display data in chunks (pages). This involves modifying the backend to support limit and skip parameters and adding "Next" or "Load More" buttons to the React frontend. Chapter 24: Get Next Page's Results – Search By Title and Rating Expands on the pagination logic by integrating search and filter capabilities. You learn how to maintain pagination state while a user searches for specific movie titles or filters by ratings, ensuring that the results remain paginated even when the dataset is filtered.
