I wanted to let you know that I released a new course on Udemy called “Display and Analyze your GIS data on the web with Leaflet.js”
This course has almost 13 hours of content on programming client-side applications with Leaflet and Turf.js. I believe it is by far the most comprehensive educational material available on Leaflet.js web mapping.
Other than the cost of the course (Now 50% off, $50 total) there are no costs using this method. It uses all open source material. Learn more or sign up at
