Question 1

How do I handle JSON files with fs-jetpack?

Accepted Answer

Use write() with an object to automatically serialize to JSON, and read() with 'json' or 'jsonWithDates' to parse it back. For example, jetpack.write('data.json', { key: 'value' }) creates a JSON file.

Question 2

fs-jetpack vs fs-extra: which is better?

Accepted Answer

Choose fs-jetpack for its cleaner API, automatic error handling, and JSON support. Opt for fs-extra if you need more comprehensive fs methods or prefer a closer drop-in replacement for native fs with additional utilities.

Question 3

How to copy files using glob patterns in fs-jetpack?

Accepted Answer

Use the copy() method with the matching option, which supports glob patterns. For instance, jetpack.copy('src', 'dest', { matching: '*.md' }) copies all Markdown files, and you can add negated patterns like '!secret.md'.

Question 4

Does fs-jetpack support file watching?

Accepted Answer

No, fs-jetpack does not include file system watchers. For monitoring changes, you need to use native fs.watch or a separate library like chokidar, which adds another dependency.

Question 5

How to create and clean up temporary directories?

Accepted Answer

Use tmpDir() to create a unique temporary directory, which returns a new jetpack context. Clean up with remove() when done, as shown in examples like dir.remove() after operations.

Question 6

Can I chain operations fluently in fs-jetpack?

Accepted Answer

Yes, methods like dir(), file(), and cwd() return jetpack objects, allowing fluent chaining. For example, jetpack.dir('foo').file('bar.txt', { content: 'text' }) creates a directory and file in one chain.
