Frontend development best practices (React.js).md

Re: selfies project written in CRA and PWA

• Planning of a project

  • The project planning is mostly based on Fullstack Project Planning.

    For most of my projects, especially recently, I've been following a planning process that helps me breakdown the project into component parts that help me build more efficiently.

• React Project Structure

  • The project structure is mostly based on React Project Structure Best Practices for Scalable Application.

    A react project structure or architecture plays an important role in project maintenance. A good folder structure will help developers in the team easy to locate and easy to relate (ELER).

• Important methodologies

  • Want to make your React site more performant? Here's a quick checklist
  • Use create-next-app for medium-to-large scale projects, while use create-react-app for small projects and if there are some integrations or libraries that just don't work very well right now with Next.

  • Using absolute (alias) imports in Javascript and VSCode.
  • Use path imports rather than named imports in order to reduce the bundle size.
    We can rely on Tree Shaking but just in case.

    Usage
    When and how to use tree-shaking?
    minimize bundle => use named or path imports? #20436
    Tree shaking does not work on dependencies of dependencies #6943
    Tree Shaking? #2748
  • Optimize images using tools like squoosh.app and svgomg and generally take the approaches from Optimize images.
    Re (opportunities often recommended by Lighthouse):
    Use WebP images
    Serve images in next-gen formats
    Properly size images
  • Set up Webpack Bundle Analyzer or source-map-explorer and monitor the bundle size of the project.
    Re (Why not use this free service?): bundle-analyzer
  • Use CSS modules to avoid overriding CSS class names, especially in CRA as styled-jsx can be used in Next.js by default.
  • Follow various opportunity recommendations reported by Lighthouse (JavaScript, CSS, Image and Core Web Vitals like LCP & CLS etc).
    Re:
    Fast load times
    Web Vitals
  • (Potential) Regularly monitor the performance by using SpeedCurve and setting up performance budgets.

  • Browser Compatibility
    • Screenshot Testing On Real Browsers & Devices via BrowserStack
    • Manifest and Favicon compatible across multiple browser platforms

• Coding practices

  • Use consistent coding style.
    Re: Airbnb JavaScript Style Guide
    • Readability
    • Modularity
    • Efficiency
    • Length
  • Use healthy third party packages using tools like bundlephobia, GitHub stars and NPM downloads.
  • Creating and keeping reusable & granular components, utilities and approaches via GitHub gist or Bit, etc.
    Benefits (my own thoughts):
    • productivity
    • upgrading and updating with ease (e.g. adopting better third-party packages)
    • codebase management

      Not all libraries can be easily broken down into parts and selectively imported. In these scenarios, consider if the library could be removed entirely. Building a custom solution or leveraging a lighter alternative should always be options worth considering. However, it is important to weigh the complexity and effort required for either of these efforts before removing a library entirely from an application.

• (Draft) Project management (Jira, GitHub issue tracker)

  • Set up Linting and repository management rules at GitHub rather than recommending devs in a team.
  • Feature request
  • Bug tracking
  • Progressive enhancement
  • Communication

• Investigating approach
