Advanced React & Storybook: From Components Library to CI/CD

Break UIs into foundational, composable, and page components to enable modular, single-responsibility design, faster development, and reusability. Build, test, and document a React-driven components library with Storybook.

Use the create-react-app cli to scaffold a React app, simplifying Webpack, dependencies, and testing setup, and learn the project structure, scripts, and how to eject for customization.

Learn to add CSS stylesheets in a React app by importing separate CSS files, leveraging webpack loaders and autoprefixing, and building production-ready styles with Create React App.

Install Storybook in a React project to build and showcase component states with stories, then run the Storybook server locally for testing, accessibility, and documentation.

Explore Storybook with the button component, using stories, controls, and args to change label, color, and size. Learn how props like primary, background, color, size, and label drive the UI.

Showcases using useState to manage a counter with an initial value zero in a functional component, updating state with the setter, avoiding direct mutation, and triggering re-renders.

Build and demonstrate an accordion component in React, with expandable items, props for title and content, state-based active toggling, and Storybook integration for visual testing.

Use useRef to access the accordion content div and dynamically set its height to the content scrollHeight when expanded, and zero when collapsed, enabling smooth transitions in a storybook demo.

Change the storybook component structure by renaming examples to components, updating titles for button, counter, and reading, and using the MDX introduction for documentation to improve user-facing navigation.

Create a reusable text input component for forms, wiring name, label, type, and placeholder props, with prop types and Storybook stories using controls and archetypes such as password and select.

Convert a text input from a DOM-managed control to a React-controlled component by binding the input value to React state, handling changes with onChange, and updating state with event.target.value.

Set up Tailwind css in a React and Storybook project by installing Tailwind, PostCSS, and Autoprefixer, generating config files, adding Tailwind directives, and styling inputs and labels with utility classes.

Style the text input component using utility classes from the css tokens, applying font size, font weight 700, shadow, appearance-none, border, radius, full-width padding, and focus or hover variants.

Discover how to use storybook to test components, boost coverage with primary and red button stories, render variants, and assert background color styles via args.

Enhance application accessibility by testing keyboard navigation, screen readers, and color contrast. Use the Storybook accessibility addon to detect violations and adjust colors to meet contrast guidelines.

Set up chromatic for storybook to run visual regression tests, generate and review snapshots for each story, and integrate with CI/CD to automate approvals and deployments.

Learn how ci/cd integrates code changes through a pipeline, automating tests and deployments, with continuous integration, continuous delivery, and continuous deployment, to boost quality, productivity, and faster releases.

Discover how to use GitHub Actions as a built-in CI/CD platform, create workflows and jobs, reuse marketplace actions, and test and build a new Node.js workflow from a repository.

Create a GitHub Actions CI workflow by adding the .github/workflows/ci.yml, configuring push or pull_request events, and a test job that runs npm install and npm test.

Fix a failing CI test by adding missing files, updating the test for the red button color, and pushing to master to retrigger the CI workflow, yielding a green success.

Integrate the code cover action from GitHub marketplace to upload code coverage in your ci workflow. Inspect coverage reports and graphs to identify untested files and improve code quality.

Add a status badge to the repository by configuring CI and code coverage badges for the master branch, paste them into the readme as markdown, and verify links.

Publish the current storybook to Chromatic and run visual regression tests in CI to ensure changes are intended, using a project token secret and reviewing build details.

Fix the visual regression test by updating the button primary variant to white, commit and push to master, triggering CI and Chromatic to verify the storybook baseline matches.

Explore how Node.js, Django, Ruby on Rails, and Next.js serve as backends for React, balancing scalability, performance, and security with features like server-side rendering and API routes.

Evaluate backend options for React apps, including ASP.NET Core, Firebase, Spring Boot, Prisma, Strapi, and GraphQL, with attention to performance, scalability, and integration trade-offs.

Discover how ChatGPT can boost coding skills with 9 examples, setup steps, and tips to avoid common pitfalls as a 24/7 programming assistant.
