Part of our work at Esri is to build open-source projects that support people building fun and new mapping applications. We are happy to announce four open source Javascript projects we've been working on in the last few months! <a href="https://github.com/Esri/esri-leaflet">Esri-Leaflet</a> is a Javascript library to help developers build lightweight applications using the Leaflet Javascript mapping library. <a href="https://github.com/Esri/geoservices-js">Geoservices.js</a> is a Javascript client for accessing ArcGIS Online services from the browser or Node.js. <a href="https://github.com/esri/terraformer">Terraformer</a> is a geometry toolkit for working with different geometry formats and building geo databases. <a href="https://github.com/esri/pushlet">Pushlet</a> is a simple API for sending notifications through the Apple and Google push notification services.
