bun-file-io

Use Bun.file for lazy file reads and Bun.write for writing content. This standardizes local filesystem tasks and speeds up Bun workflows by enforcing Bun APIs over node:fs.

Use Bun.Glob for file scans and directory discovery. It handles filesystem searches across directories efficiently, standardizing batch reads and cleanup operations in Bun scripts.

Bun file I/O does not completely replace node:fs. You should prefer Bun APIs for reading, writing, and scanning, but revert to node:fs for specific directory operations or compatibility scenarios.

Yes, you can perform safe existence checks and batch reads with Bun. Use Bun.file to check if a file exists and read its content lazily, which optimizes filesystem management across directories.

Use Bun.write instead of node:fs when you need to write files or perform incremental writes to large files. It is standardized for Bun-powered scripts and tooling to ensure faster workflows.
