Once caches command output in a per-user background daemon

github.com 5 min read Editor score 6/10

Once caches a command's stdout by command, directory and tenant key, then serves repeats from memory until its TTL expires; the example avoids repeated 1Password fingerprint prompts. Its tenant scoping and expiry model may interest engineers handling local secrets or CLI workflows.

What: Once runs a command and caches its stdout in a small per-user background daemon for reuse.
How: Cache entries are keyed by command, directory, and tenant; they expire by time limits, and commands that exit non-zero are not cached.
Why it matters: It can avoid repeated interactive approvals for commands such as reading secrets, while preserving prompts and returning command exit codes.

Once routes calls through a daemon that runs commands on cache misses and stores their stdout. Sketched from the article's own text.
