copy a file in typescript

To copy a file in TypeScript, you can make use of the file system module provided by Node.js. Here's an example code snippet:

index.ts
import * as fs from "fs";

const source = "path/to/source/file.txt";
const destination = "path/to/destination/file.txt";

fs.copyFile(source, destination, (err) => {
  if (err) throw err;
  console.log("File copied successfully!");
});

10 lines

In this code, we import the fs module and specify the source and destination paths of the files that we want to copy. We then call the copyFile function, passing in the source path, the destination path, and a callback function. The callback function is called with an error object if an error occurs during the copy process.

When the copy is complete, the callback function is invoked with a null error value, indicating that the copy was successful. At this point, you can perform any additional processing that you need to do with the copied file.
