What are common pitfalls with dynamic import?

Dynamic imports in JavaScript can be incredibly useful for optimizing loading times and improving the performance of applications. However, there are several common pitfalls developers may encounter when using dynamic imports:

  • Not Handling Errors Properly: When using dynamic imports, it's essential to handle potential errors that may arise, such as the module not being available or network issues.
  • Overusing Dynamic Imports: While dynamic imports can reduce initial loading times, overusing them may lead to excessive requests and impact performance negatively.
  • Incorrect Module Path: Dynamic imports require the correct path to the module. A typo or incorrect path can result in runtime errors.
  • Bundling Issues: Some build tools may not handle dynamic imports well, leading to unexpected behavior or increased bundle sizes.
  • Performance Hits from Multiple Imports: Importing numerous modules dynamically at once can lead to performance degradation. It's better to load modules as needed.
