Question 1

How to use fs-extra with async/await?

Accepted Answer

Call the async methods without a callback—they return promises. For example, use `await fs.copy(src, dest)` inside a try/catch block for error handling, as shown in the README examples.

Question 2

fs-extra vs native fs/promises: which is better?

Accepted Answer

Use fs-extra if you need extra utilities like recursive copy or JSON handling; it consolidates multiple packages. For basic promise-based operations, Node.js's built-in fs/promises is lighter and sufficient.

Question 3

Does fs-extra work with TypeScript?

Accepted Answer

Yes, but type definitions are separate. Install @types/fs-extra from DefinitelyTyped for full TypeScript support, as noted in the README's Third Party section.

Question 4

How to copy a directory recursively with fs-extra?

Accepted Answer

Use the copy() method, which handles recursion automatically. For instance, `fs.copy('/source', '/destination')` copies all files and subdirectories, with options for overwriting.

Question 5

What happened to the walk function in fs-extra?

Accepted Answer

It was removed in version 2.0.0. The README recommends using separate packages like klaw or klaw-sync for directory walking, as fs-extra no longer includes this feature.

Question 6

Is fs-extra suitable for production use?

Accepted Answer

Yes, it's widely adopted with millions of downloads, active maintenance, and comprehensive testing. The integration of graceful-fs adds reliability for production file operations.

Question 7

How to handle errors in fs-extra async methods?

Accepted Answer

Use promise catch blocks or try/catch with async/await. For example, wrap `await fs.remove(path)` in a try block to catch errors like permission issues, as demonstrated in the README.
