maplicate-core v0.1.0

maplicate-core

maplicate-core is a thin layer for OrbitDB, a distributed peer-to-peer database, with convenient APIs for working with geographic data and mapping library (like Leaflet). It is designed for building decentralized and offline-first map applications.

Each maplicate node is an OrbitDB DocStore, which provides:

• full CRUD functions for map features (in GeoJSON format)
• feature level events for feature edits

Example

const IPFS = require('ipfs');
const OrbitDB = require('orbit-db');

import { MaplicateNode } from 'maplicate-core';

const ipfs = new IPFS();

ipfs.on('ready', () => {
  // initialize an OrbitDB instance
  const orbitdb = new OrbitDB(ipfs);

  // create a maplicate node instance with an address
  const maplicateNode = new MaplicateNode(orbitdb, 'map_address');

  maplicateNode.on('feature:added', (feature) => {
    // update your map view when a map feature is added by other peers
  });
});

For more details, see the API documentation and event guide.
