Found as Example but Outdated

Frustrated about getting old and outdated hints for development I wish to clean up the blogs but also define some best practices I like to see as a standard when blogging about solutions or implementing components.
Web applications should not be coded to support outdated browsers for several reasons:
-
Security Risks: Outdated browsers often lack critical security updates, making users vulnerable to attacks. Supporting them encourages unsafe browsing habits.
-
Development Overhead: Ensuring compatibility with old browsers increases development and testing time, leading to higher costs and slower release cycles.
-
Limited Features: Modern web standards (like ES6, CSS Grid, Flexbox) are not supported in outdated browsers, restricting the use of efficient, maintainable, and performant code.
-
Poor User Experience: Workarounds for old browsers can degrade the experience for users on modern browsers.
-
Vendor Support: Browser vendors discontinue support for old versions, so issues may never be fixed.
Focusing on modern browsers allows developers to deliver secure, performant, and feature-rich applications.
Popular Web Frameworks and Their Browser Support
Framework | Supported Browsers (as of 2024) | Notes on Old Browser Support |
---|---|---|
React | Latest 2 versions of major browsers (Chrome, Firefox, Safari, Edge) | IE11 and below are not supported |
Angular | Evergreen browsers (Chrome, Firefox, Safari, Edge) | IE11 support dropped in Angular 13 |
Vue.js | Latest versions of Chrome, Firefox, Safari, Edge | IE11 support dropped in Vue 3 |
Svelte | Modern browsers (Chrome, Firefox, Safari, Edge) | No support for IE11 or legacy browsers |
Next.js | Latest stable browsers | No support for IE11 |
Nuxt.js | Latest stable browsers | No support for IE11 |
Note: Most modern frameworks have officially dropped support for Internet Explorer and other outdated browsers, focusing on security, performance, and modern web standards.
Relation to Font File Formats
Modern font file formats (such as WOFF, WOFF2, and variable fonts) are supported only in up-to-date browsers. Outdated browsers may not recognize these formats, forcing developers to include legacy formats like TTF, EOT, or SVG for compatibility. This increases asset size and complexity. By targeting modern browsers, developers can use efficient, compressed font formats, improving load times and reducing maintenance.
