L.TileLayer.Canvas

Render Leaflet's tiles as <canvas> elements.

Why?

If your project has a lot of layers, sometimes performance issues related to GPU may occurred. In our case the easiest way to avoid them is displaying map's tiles not as <img> elements, but draw their on the <canvas>. Just look:

How to use it?

You can install it via package manager:

npm install tilelayer-canvas

or

yarn add tilelayer-canvas

or just copy index.min.js from this repository and include it by <script> tag:

<script src="./path/to/index.min.js"></script>

Then in your project use L.tileLayer.canvas instead of L.tileLayer. That's it! See an example.

Options

Name	Required	Default value	Description
timeout	No	undefined	Zoom debounce time.
doubleSize	No	undefined	Set to true if tiles are 2x.
