To use dynamic imports in serverless functions, you can follow these steps:
- Create a JavaScript file (
example.js
) that contains the code you want to dynamically import:// example.js export function doSomething() { console.log("Doing something..."); }
- In your serverless function file, use the
import()
function to dynamically import the module: ```javascript // serverless.js exports.handler = async (event, context) => { const { doSomething } = await import(‘./example.js’); doSomething();
return { statusCode: 200, body: “Dynamic import successful!”, }; }; ```
In the example above, the import()
function, when called, returns a Promise. await import('./example.js')
waits for the dynamically imported module to resolve, and then you can access the exported functions or variables. In this case, we retrieved the doSomething
function and invoked it.
It’s important to note that dynamic imports may not be supported in certain environments or older browsers. To ensure compatibility, consider using a transpiler like Babel or checking the compatibility table on MDN Web Docs.
Using dynamic imports with serverless functions can enhance code modularity and flexibility. By loading modules on-demand, you can optimize the performance of your serverless applications.
Happy coding! 🚀
