name: domain-normalizer description: Use when implementing or debugging code that uses @suaveplan/domain-normalizer: Normalisation, matching, and alias-canonicalisation for internet domain names.

@suaveplan/domain-normalizer

Normalisation, matching, and alias-canonicalisation for internet domain names. Given heterogeneous URL or domain input — including common mobile/CDN subdomains and 31 built-in alias mappings (e.g. m.youtube.com → youtube.com, old.reddit.com → reddit.com) — this package produces a canonical registrable domain via tldts, strips www/m/mobile prefixes, resolves the alias map, and returns structured NormalizedDomain objects. It also provides Levenshtein-based similarity scoring (computeSimilarity), fuzzy matching (matchDomains), and a groupDomains function that clusters a mixed list by canonical root domain. Use this package for deduplicating contact email domains, canonicalising URLs before storage, and building domain-level blocklists. For full entity deduplication across arbitrary fields use @suaveplan/dedup; for MIME or URL content-type detection use @suaveplan/mime.

When to use this skill

• Implementing or debugging code that imports @suaveplan/domain-normalizer.
• The task touches: see package README.
• You need API guidance for this package's exports.

Quick reference

import { /* see API Reference below */ } from "@suaveplan/domain-normalizer";

Where to read more

This skill is intentionally short. The package's own documentation is the authoritative source — read these in order:

1. packages/foundation/domain-normalizer/README.md — overview, install, quick-start, module index
2. packages/foundation/domain-normalizer/src/**/*.md — co-located docs per implementation file (Purpose, Features, Basic + Advanced examples, full API reference, Implementation notes — all packages ship ≥200 words per module)
3. packages/foundation/domain-normalizer/package.json exports map — every subpath you can import from

When the user asks an API question, read the relevant co-located .md first; do not answer from training-data memory.
