Bootstrap Native: Using Bootstrap Components without jQuery

This article explores Bootstrap Native, a project aiming to replace jQuery in Bootstrap's JavaScript components with plain JavaScript. Let's delve into its benefits, usage, and limitations.

Key Advantages of Bootstrap Native:

• Enhanced Performance: Plain JavaScript generally outperforms jQuery, leading to faster execution and a more responsive user experience.
• Reduced File Size: Bootstrap Native significantly reduces the overall JavaScript footprint. A comparison shows that Bootstrap with jQuery ranges from 36.5KB to 50KB (minified and gzipped), while Bootstrap Native, including polyfills, ranges from 8.9KB to 19.9KB. This smaller size contributes to faster page load times.
• Simplified Development: By eliminating jQuery, development becomes cleaner and potentially easier to manage.

Browser Compatibility and Polyfills:

Bootstrap Native boasts broad browser support, including older versions like IE8 , achieved through polyfills. Two options are available: Polyfill.io (a service providing browser-specific polyfills) and minifill (a lightweight custom polyfill).

Implementation:

Integrating Bootstrap Native is straightforward. Replace the standard Bootstrap JavaScript files with Bootstrap Native's bootstrap-native-v4.min.js (available via CDN or local download), and include the chosen polyfill (if needed) in the section.

Limitations:

Bootstrap Native isn't a complete, feature-for-feature port. Some less-used functionalities have been omitted for performance optimization. Key differences include:

• Custom Events: While Bootstrap extensively uses custom events, Bootstrap Native only provides them for the Carousel and Button components. However, you can easily implement them for other components using the CustomEvent API.
• Programmatic API: Bootstrap offers a rich programmatic API for controlling components. Bootstrap Native often lacks this level of control for components like Modal, Dropdown, Tab, Alert, and Carousel.
• Other Minor Differences: Subtle variations exist in other components; for example, the dropdown menu's behavior differs slightly.

Conclusion:

Bootstrap Native presents a compelling alternative for developers prioritizing performance and preferring plain JavaScript. While it doesn't perfectly mirror Bootstrap's jQuery version, its benefits often outweigh the minor functional differences. The project's active development and responsive community support further enhance its appeal. Consider its strengths and limitations carefully before integrating it into your next project.
