confbox

Config parsers for:

✅ YAML (with js-yaml)

✅ TOML (with smol-toml)

✅ JSONC (with jsonc-parser)

✅ JSON5 (with json5)

✅ JSON

With perfect bundling:

✨ Types exported out of the box

✨ Zero config and compact redistribution

✨ Dual ESM/CJS build

✨ Consistent and tested API

✨ Handpicked best libraries (bundle+perf)

✨ Auto detects indentation and whitespace when parsing and preservers when serializing

[!NOTE] Use unjs/c12 for a full featured configuration loader!

# ✨ Auto-detect
npx nypm install confbox
