ichibin v0.0.3

ichibin

Ichibin is a Node.js library to convert location (longitude and latitude) to address. It currently supports Japan only.

Currently, the following features are supported:

• Using MongoDB for data backend
• Downloading MLIT data for reverse-geocoding

Installation

$ npm install --save ichibin

or

$ yarn add ichibin

Usage

To use ichibin for reverse-geocoding, you need to seed data:

$ ./node_modules/.bin/ichibin seed

Then, you can do reverse-geocoding:

const Ichibin = require('ichibin');
const ichibin = new Ichibin();
const lon = 141.321212;
const lat = 43.037301;

ichibin.getAddress(lon, lat).then((result) => console.log(result));
