OSM Changeset Viewer on a GL Map

Contributor Covenant

Changeset viewer module for osmcha.org (Example, Github).

Pass a changeset id to render details of changes made by that changeset on a MapboxGL map.

Heavily inspired by the ACHAVI Changeset Viewer (Example, Github).

Use as a module

Create a container div to hold the UI.

<div id='container'></div>

// es6 modules
import {getChangeset, query, propsDiff, render} from 'changeset-map';

// commonjs
var changesetMap = require('changeset-map');
var render = changesetMap.render;

var container = document.getElementById('container');
var changesetMapControl = render(container, changesetID, { width: '1000px', height: '1000px' });

// binding events
changesetMapControl.on('load', function () {
    changesetMapControl.emit('selectFeature', 'node|way', featureId);
    changesetMapControl.emit('clearFeature');
    changesetMapControl.on('hashchange', function(geometryType, featureId) {
        // update hash.
    });
})

For a custom overpass instance, set a overpassBase key in the options object. Default instance is https://overpass.osmcha.org/api/interpreter.
