Article Index Page: Implementation, Testing, And Stories

Creating an index page for articles involves several key steps, including setting up dependencies, defining acceptance criteria, and detailing the implementation process. This comprehensive guide will walk you through each stage, ensuring a robust and user-friendly index page for your articles. This article will provide a thorough understanding of how to develop, test, and integrate an index page for articles within a web application. By following this guide, developers can ensure a seamless user experience while adhering to best practices in software development.

Dependencies

Before diving into the implementation, it's crucial to address the necessary dependencies. Dependencies are the building blocks that allow different parts of your application to work together seamlessly. The primary dependencies for this task include:

  • Creating Fixtures for Articles: Fixtures are essential for populating your database with sample data, which is crucial for testing and development. They provide a consistent dataset, allowing you to test various scenarios and ensure your index page functions correctly. Creating these fixtures involves defining the structure and content of the articles, ensuring they align with your application's data model.

  • Table Component for Articles: A table component is the visual representation of your article data. It needs to be designed to display the data in a clear, organized, and user-friendly manner. This involves selecting the appropriate columns, implementing sorting and pagination, and ensuring the table is responsive across different devices.

  • Copy Placeholders for Articles Pages; Add to App.js/AppNavbar.js: Placeholders serve as temporary content and navigational elements that help structure your application before the actual content is integrated. Copying these placeholders and adding them to your main application files (App.js and AppNavbar.js) sets the stage for integrating the articles index page into the broader application structure. This step ensures that the necessary routes and navigation links are in place.

Ensuring these dependencies are in place before you start the main implementation will save you time and prevent potential roadblocks later on. By addressing these foundational elements, you create a solid base for building a functional and user-friendly articles index page. It's essential to approach these dependencies with attention to detail, as they directly impact the overall quality and usability of the final product.

Acceptance Criteria

Acceptance criteria are the specific conditions that must be met for the implementation to be considered successful. They provide a clear understanding of the expected functionality and user experience. For the articles index page, the acceptance criteria are as follows:

  • Data Population: When a user navigates to the /articles route, the page should display all rows from the database. This ensures that all available articles are visible and accessible. The data should be presented in a readable and organized format, typically within a table component.

  • Admin User Privileges: Administrators should have additional capabilities on the index page. They should see buttons to create new articles, edit existing ones, and delete records. These features are essential for managing the content and maintaining the database. The visibility of these buttons should be exclusive to admin users, ensuring that regular users do not have access to these administrative functions.

  • Regular User Restrictions: Regular logged-in users should only be able to view the data in the table. The create, edit, and delete buttons should not be visible to them. This restriction ensures data integrity and prevents unauthorized modifications. The primary focus for regular users is to access and read the articles.

  • Edit Button Navigation: When an admin user clicks the edit button for a record, they should be navigated to the corresponding edit page URL. This functionality links the index page to the editing interface, allowing for seamless content updates. If the edit page implementation is not yet complete, a blank page with the correct URL should be displayed, indicating that the navigation is functioning as expected.

  • Delete Button Functionality: The delete button, accessible to admin users, should call the appropriate endpoint to remove the record from the database. After deletion, the page should refresh, and the deleted record should no longer be visible. This ensures that the database and the user interface are synchronized.

  • PR Requirements: The pull request (PR) description should include a screenshot of the new articles index page. This provides a visual reference for reviewers and stakeholders to understand the changes. Additionally, the PR description should link to the published Storybook story for the ArticlesIndexPage component, allowing for interactive review and testing of the UI component.

Adhering to these acceptance criteria ensures that the articles index page meets the required functionality and provides a consistent user experience. It also helps in maintaining code quality and facilitates collaboration among developers.

Implementation Details

The implementation phase is where the actual coding and integration take place. This section outlines the specific steps and considerations for building the articles index page.

  • Backend API Familiarization: Before starting the implementation, it is crucial to refamiliarize yourself with the backend CRUD (Create, Read, Update, Delete) API endpoints for articles. The Swagger page is an invaluable resource for understanding the available endpoints, their required parameters, and expected responses. This step is essential to ensure that your frontend code correctly interacts with the backend.

  • Leveraging Existing Code: The implementation process can be streamlined by leveraging existing code from similar components, such as RestaurantIndexPage.js and UCSBDatesIndexPage.js. These components likely use backend API endpoints similar to those for articles. However, it's important to verify and use the exact API endpoint names for articles to avoid errors. Copying and adapting code from these existing components can significantly reduce development time and ensure consistency across the application.

  • Modifying ArticlesIndexPage.js: This file is where the main logic for the articles index page resides. Replace the placeholder content with the actual implementation, modeled after the RestaurantIndexPage.js and UCSBDatesIndexPage.js files. This involves fetching article data from the backend API, rendering the data in a table format, and implementing the create, edit, and delete functionalities for admin users. Ensure that the API endpoint names are correctly used for the articles table.

  • Modifying ArticlesIndexPage.test.js: The test file needs to be updated to reflect the new functionality of the articles index page. Replace the placeholder content with tests modeled after the RestaurantIndexPage.test.js and UCSBDatesIndexPage.test.js files. These tests should cover various scenarios, such as data fetching, rendering, and user interaction. Correct API endpoint names are crucial in this file to ensure accurate testing.

  • Creating ArticlesIndexPage.stories.js: This file is part of the Storybook setup, which allows for the isolated development and testing of UI components. Create this file under frontend/src/stories/pages/Articles/, following the examples provided by RestaurantIndexPage.stories.js and UCSBDatesIndexPage.stories.js. This file should define stories that showcase the different states and functionalities of the articles index page, such as displaying data, handling loading states, and rendering admin-specific controls.

By following these implementation steps and paying close attention to detail, developers can create a robust and functional articles index page that meets the specified requirements. It's crucial to continuously test and verify the implementation to ensure its reliability and performance.

Reminders (All in frontend Directory)

Before proceeding with the development, it is essential to keep several reminders in mind to ensure a smooth and efficient process. These reminders cover various aspects of the development environment, testing, and code quality.

  • Node Version Management: Always start by setting your Node.js version using nvm use 22.18.0. This ensures that you are working with the correct version of Node.js, which is crucial for compatibility and avoiding potential issues. Node Version Manager (nvm) allows you to easily switch between different Node.js versions, making it an indispensable tool for managing your development environment.

  • Running Storybook Locally: To run Storybook locally, use the command npm run storybook. Storybook is a powerful tool for developing UI components in isolation. It allows you to create, test, and showcase your components without the need to run the entire application. This is particularly useful for developing and testing the ArticlesIndexPage component and its various states.

  • Running Tests and Checking Coverage: To run tests and check test coverage locally, use the command npm test. Testing is a critical part of the development process. It ensures that your code functions as expected and helps identify potential bugs early on. Test coverage provides insights into how much of your code is being tested, helping you identify areas that may need additional testing.

  • Formatting with Prettier: To fix formatting issues, use the command npm run format. Prettier is a code formatter that automatically formats your code to adhere to a consistent style. This helps maintain code readability and consistency across the project. Running this command ensures that your code is properly formatted before committing it.

  • Linting Checks: To check linting locally, use the command npx eslint --fix .. ESLint is a static analysis tool that identifies and automatically fixes coding style issues. Linting helps enforce coding standards and best practices, ensuring code quality and consistency. Running this command before committing your code can help catch and fix potential issues early on.

  • Mutation Coverage Checks: Mutation testing is a more advanced form of testing that helps ensure the effectiveness of your tests. It involves making small changes (mutations) to your code and verifying that your tests catch these changes. To check mutation coverage locally, use the command npx stryker run. This command performs a full mutation test run, which can be time-consuming. For a faster check on a single file, use the command npx stryker run -m src/main/pages/Articles/ArticlesIndexPage.js. Mutation testing provides a higher level of confidence in your test suite.

By adhering to these reminders, developers can maintain a clean, consistent, and well-tested codebase, which is essential for the long-term maintainability and reliability of the application.
