To use dynamic imports, you need to specify the path to the module you want to import as a string. This path can be dynamically generated based on user interactions or other conditions in your application.
Here’s an example of how you can use dynamic imports in a PWA:
const button = document.querySelector('#myButton');
button.addEventListener('click', async () => {
// Dynamically import the module when the button is clicked
const module = await import('./myModule.js');
// Use the imported module
module.myFunction();
});
In this example, when the button with the id “myButton” is clicked, the import
function is called with the path to the module “myModule.js”. The import
function returns a promise, so we can use await
to wait for the module to be loaded before using it.
Once the module is imported, you can access its exported functions, classes, or variables. In this example, we assume that “myModule.js” exports a function called myFunction
, which can be called using module.myFunction()
.
Dynamic imports can be a powerful tool for optimizing the loading time of your PWAs. By deferring the loading of non-critical modules until they are actually needed, you can improve the initial load time and provide a better user experience.
Remember that dynamic imports are supported in modern browsers but may not be available in older browsers. If you need to support older browsers, you can use tools like Babel or webpack with appropriate plugins to transform dynamic imports into a format that is compatible with older browsers.
