Dynamic Import vs Require Statements

Developers should use Dynamic Import to optimize web applications by reducing initial bundle sizes and improving load times, especially for large single-page applications (SPAs) or features that are not immediately required meets developers should learn and use require statements when working in node. Here's our take.

Dynamic Import

Nice Pick

Developers should use Dynamic Import to optimize web applications by reducing initial bundle sizes and improving load times, especially for large single-page applications (SPAs) or features that are not immediately required

Pros

• It's essential for implementing lazy loading of routes, components, or libraries in frameworks like React, Vue, or Angular, and for conditionally loading polyfills or modules based on user interactions or device capabilities
• Related to: javascript, es-modules

Cons

• Specific tradeoffs depend on your use case

Require Statements

Developers should learn and use require statements when working in Node

Pros

• js environments or with build tools like Webpack that support CommonJS, as they are essential for importing modules from the local filesystem or npm packages
• Related to: commonjs, node-js

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Dynamic Import if: You want it's essential for implementing lazy loading of routes, components, or libraries in frameworks like react, vue, or angular, and for conditionally loading polyfills or modules based on user interactions or device capabilities and can live with specific tradeoffs depend on your use case.

Use Require Statements if: You prioritize js environments or with build tools like webpack that support commonjs, as they are essential for importing modules from the local filesystem or npm packages over what Dynamic Import offers.

The Bottom Line

Dynamic Import wins

Developers should use Dynamic Import to optimize web applications by reducing initial bundle sizes and improving load times, especially for large single-page applications (SPAs) or features that are not immediately required
