how to use the writesync function from the fs-extra library in typescript

To use writeFileSync function from the fs-extra library in TypeScript, first, you need to import the library:

index.ts
import * as fse from 'fs-extra';

2 lines

Once you have imported the fs-extra library, you can use the writeFileSync function to write the content to a file synchronously. Here's an example:

index.ts
try {
  const path = '/path/to/file.txt';
  const content = 'Hello, world!';
  fse.writeFileSync(path, content);
  console.log('Content written successfully!');
} catch (err) {
  console.error(err);
}

In the example above, we have used the writeFileSync function to write the content "Hello, world!" to the file /path/to/file.txt synchronously. If there is an error while writing the content to the file, it will be caught in the catch block and the error will be logged to the console.

Note that the writeFileSync function blocks the execution of the program until the content is written to the file. If you need to write the content to a file asynchronously, you should use the writeFile function instead.
