Welcome to the Dutch Postcode API written in go! This API provides a simple and efficient way to retrieve location information based on Dutch postcodes. Whether you're building a location-based application or need to enhance your data with geographical details, this API has got you covered.

Features

  • Accurate Data: Utilizes up-to-date Dutch postcode data from "Basisregistratie Adressen en Gebouwen (BAG)".
  • Easy Integration: Simple RESTful API design for easy integration into your applications.
  • SQLite Database Export: Easily extract addresses as an SQLite database from the Docker container.
  • Compact Image Size: The Docker image is optimized for efficiency, with a small size of only 364.96 MB.

Getting Started

  1. Run the docker container
docker run -p 80:80 ghcr.io/maantje/postcode:latest
  1. Wait for the database to be extracted

  2. done!

Usage

Endpoint

GET /postcode/{postcode}/{house_number}

Replace {postcode} and {house_number} with the desired postcode and house number.

Example

curl -X GET http://localhost/postcode/9743EG/258

Extracting the database

The Docker image includes an SQLite database containing all Dutch addresses. Follow these steps to extract the database after starting the container.

  1. Identify the container ID:
docker ps
  1. Extract the SQLite database:
docker cp {CONTAINER ID}:/application/database/addresses.sqlite addresses.sqlite

You now have the addresses.sqlite file containing all Dutch addresses in your current directory.
