@danadresse/client

Official JavaScript / TypeScript client for Danadresse — the drop-in replacement for the Danish Address Web API (DAWA, closing 17 August 2026).

npm install @danadresse/client

Quick start

import { DanadresseClient } from '@danadresse/client'

const api = new DanadresseClient({ apiKey: 'dawa_live_…' })

// Typo-tolerant autocomplete (same as DAWA /autocomplete)
const hits = await api.autocomplete('Rådhuspladsen')
console.log(hits[0].tekst) // "Rådhuspladsen 1, 1550 København V"

// Reverse geocoding
const addr = await api.reverse(12.5683, 55.6761)

// Address cleansing / datavask
const result = await api.datavask('Radhuspladsen 1 KBH')
console.log(result.kategori) // "A"

// Full property bundle: BBR + valuation + zoning + energy (beyond DAWA)
const property = await api.enrichAll('<address-uuid>')

Migration from DAWA

Migrating from dawa.aws.dk? Change one line:

- const BASE = 'https://api.dataforsyningen.dk'
+ const BASE = 'https://api.danadresse.dk'

Or use this client — same endpoints, same parameters, same JSON shapes:

| DAWA endpoint | Danadresse method | |---|---| | GET /autocomplete?q=… | api.autocomplete(q) | | GET /adresser | api.adresser(params) | | GET /adresser/{id} | api.adresse(id) | | GET /adgangsadresser/reverse | api.reverse(x, y) | | POST /datavask/adresser | api.datavask(betegnelse) | | GET /postnumre | api.postnumre() |

API key

Get a free key (1 000 calls/month, no credit card) at danadresse.dk/dashboard/signup.

Pass it as X-Api-Key header or ?api_key= query param — this client handles both via the constructor.

Enrichment (beyond DAWA)

// BBR building data
const bbr = await api.enrichBbr(adresseId)

// Energy label (EMO)
const energi = await api.enrichEnergi(adresseId)

// Property + zoning + valuation
const ejendom = await api.enrichEjendom(adresseId)

// Everything in one call
const all = await api.enrichAll(adresseId)

See danadresse.dk/ejendom for the full property data reference.
