bun-fs-helpers

Bun-native filesystem helpers use Bun.spawn with array arguments and Bun.file() to eliminate command injection vectors. They provide pathExists, readTextFile, writeTextFile, and directory operations with zero node:fs dependencies, ensuring safe file handling in Bun-first environments.

Yes. readJsonFile and writeJsonFile use Bun.file() for pure Bun-native JSON operations. Both async and sync variants are available, reducing token overhead and eliminating Node.js filesystem module dependencies.

Use pathExists to check file presence and stat for detailed metadata. TOCTOU protection via stat before and after operations prevents race conditions in automation, tooling, and build workflows.

Bun-native helpers cover file existence checks, reading and writing text and JSON, copying and moving files, deleting, listing directories, SHA256 hashing, and deep equality checks—all designed for build and automation tasks without external dependencies.

Yes. ensureDir and readDir use Bun.spawnSync with array arguments to prevent injection. These utilities safely create, list, and traverse directories in Bun-first environments.

sha256 and sha256File provide command-injection-safe hashing using Bun-native utilities. Both functions support fast file verification and integrity checks in build and automation workflows.
