About the Book

Leaflet Tips and Tricks is currently being updated to align it with the 1.x release version. The content is still good and relevant even while it is being updated, so feel free to download a copy and check frequently to get the latest (free!) updates.

leaflet.js can help you make the interactive maps YOU want.

Laeflet Tips and Tricks is a book written to help those who may be unfamiliar with JavaScript or web page creation get started bringing their map vision to the World.

Maps and geographic information is the new medium of choice for presenting compelling information and providing location context on the Internet and leaflet.js is an extraordinary library for presentation of maps on a web page.

Is this book for you?

It's not written for experts. It's put together as a guide to get you started if you're unsure what leaflet.js can do. It reads more like a story as it leads the reader through the basics of a simple map with advice on getting started and the sort of things that will help you expand your knowledge.

This book was originally written and published in 2014. Since then Leaflet has continued to grow in popularity. The plan is for me to update the book for the 1.x release of Leaflet

Why was Leaflet Tips and Tricks written?

Because in the process of learning things, it's a great way to remember them if you write them down :-).

As a result, learning how to do cool stuff with maps and Leaflet meant that I accumulated a sizeable number ways to help me out when the going got tricky. Then I realised that these could be useful for others who were trying out leaflet.js and who were at a similar knowledge level.

So here we are! A collection of tips and tricks for leaflet.js written by a noob for people who might consider that they're in the same situation :-).

What's in the book?

I've captured the appropriate code (in cool looking coloured text) and added in illustrations of what's going on so that you will get more traction at the start of your learning process than I did.

Download the whole book just to try it out!

I'm making the book available for free because I think it's a great way to give something back to the community as a whole, but if you find some value in the book, please consider contributing $4.99 when you download it so that Leanpub get something for hosting the book and providing such an awesome service (50 cents + 20% is their cut of any book sales and $4.99 is the minimum (apart from $0) that they will allow for a sale).

Enjoy.

So I hope you get something out of the book, please excuse the sometimes light-hearted conversational manner in which I approach the topic and enjoy Leaflet!

I'm a person who has a passion for knowledge and I realise that part of the responsibility of gathering knowledge is being able to advance the state of the human condition in some way.

My aims using Leaflet and in writing this book were to build on the previous success of writing D3 Tips and Tricks, play with software and try something new for fun. It also helps that I think maps and the visual representation of data rock in serious ways.

I don't have a formal coding background and I didn't learn JavaScript in a structured way. I learnt a little bit of JavaScript as a result of using d3.js, so the way I explain things is focussed on trying to impart that understanding in a simple but functional way.

I'm totally in awe of the Open Source community that has made this type of work possible, which is why you can download Leaflet Tips and Tricks for free.

Feel free to follow me on Twitter (@d3noob), I find it a great service to get alerted to what's going on with Leaflet and D3.
