Project Setup

Initialize the foundation for your frontend project.

•

Initialize version control repository

Run git init, create a remote repository, and set up .gitignore.

•

Choose and configure package manager

Select npm, Yarn, or pnpm and initialize the project with a lockfile.

•

Set up linting and formatting

Install ESLint and Prettier, create config files, and add npm scripts for linting.

•

Configure module bundler or build tool

Set up Vite or Webpack with a basic config for development and production builds.

UI/UX Design

Plan the user interface and experience before writing code.

•

Create low-fidelity wireframes

Sketch wireframes for each page to outline layout and navigation.

•

Design high-fidelity mockups

Use Figma or Sketch to produce detailed visual designs.

•

Define design system tokens

Establish colors, spacing, typography, and shadow values as CSS variables.

•

Document reusable components

Add components to Storybook with usage notes and props documentation.

HTML & Semantics

Write meaningful, accessible markup that supports SEO and assistive tech.

•

Use semantic HTML5 elements

Replace divs with header, nav, main, section, article, footer where appropriate.

•

Ensure proper heading hierarchy

Structure headings from h1 to h6 without skipping levels.

•

Add ARIA labels and roles

Supplement native semantics with ARIA attributes for custom widgets.

•

Include essential SEO meta tags

Add title, description, viewport, and Open Graph tags for search and social sharing.

Styling & CSS

Apply maintainable, responsive styles that adapt to various devices.

Adopt a CSS methodology

Choose BEM, SMACSS, or similar and enforce naming consistency across the project.

Organize code into reusable ES modules

Separate concerns by exporting functions, classes, or components from individual files.

•

Manage application state

Select Context API, Redux, or Vuex based on complexity and team familiarity.

•

Handle DOM events efficiently

Use event delegation, debounce, and throttle to prevent performance bottlenecks.

Testing, Build & Deployment

Ensure quality through testing and automate delivery to production.

•

Set up unit testing framework

Install Jest or Vitest and write tests for utility functions and components.

•

Conduct integration tests

Use React Testing Library or Vue Test Utils to test component interactions.

•

Configure end-to-end testing

Set up Cypress or Playwright to simulate user journeys and catch regressions.

•

Establish CI/CD pipeline

Create GitHub Actions workflow to run tests, build, and deploy on each push.
