Then, you can import the cpsync function from the fs-extra library and use it in your TypeScript code. For example:

index.ts
import { cpsync } from 'fs-extra';

const sourceDir = '/path/to/source/dir';
const destDir = '/path/to/dest/dir';

cpsync(sourceDir, destDir, {
  filter: (src: string, dest: string) => {
    // return true if the file should be synced, false if not
  },
  updateOnly: true // set to true to copy only newer files
}).then(() => {
  console.log('File synchronization complete.');
}).catch((err: Error) => {
  console.error('File synchronization failed:', err);
});

Here, we are synchronizing the files from the sourceDir directory to the destDir directory using the cpsync function. We are also passing some options to the function, such as a filter function and an updateOnly flag to only copy newer files.

Note that the cpsync function is asynchronous and returns a Promise. We are handling this promise using then and catch blocks to log the result of the operation or any errors that may have occurred.
