Low-level module graph traversal for Bare

Drop-in replacement for `fs.existsSync` with zero dependencies. Other libs I found either have crucial differences from fs.existsSync, or unnecessary dependencies. See README.md for more info.

In-memory filesystem with Node.js fs-compatible API

Allows users to use generators in order to write common functions that can be both sync or async.

Use multiple `fs` modules in a union.

Filesystem-buffered, passthrough stream that buffers indefinitely rather than propagate backpressure from downstream consumers.

Promisify a callback-style function

Use @vercel/edge-config instead.

i18next-fs-backend is a backend layer for i18next using in Node.js and for Deno to load translations from the filesystem.
