react-leaflet VS OpenLayers3

30.react-leaflet

Check out React Leaflet https://react-leaflet.js.org/

But in the case of React Leaflet, you may need to put in some more efforts.

You might wanna check out Leaflet (https://leafletjs.com/) which is a free, open-source library for interactive maps. Combine that with React-Leaflet (https://react-leaflet.js.org/) for seamless React integration. You can find Pond/Lake GeoJSON data at https://gis.mass.gov/ and load it into your map to make it interactive. Good luck!

Leaflet has many official and third party plugins and wrappers. Since we’re using React, we can use React Leaflet which provides components for rendering Leaflet maps in React.

Do you need to just make an image that looks like a map, or do you need to make an actual map (i.e. derived from spatial data)? I think leaflet is still the go to OSS webmap library, and will do hexbins. It has a react version.

I wanted to update the react-leaflet version in my project. On the github and npm page for the package it says the latest version is 4.2 https://www.npmjs.com/package/react-leaflet. When I ran an npm update react-leaflet it updated the version from 3.0.1 to 3.2.5. Why isn't it 4.2?

You probably know this, but in Google Maps at least, you can use browser zoom (ctrl/cmd +/-) to change the size of labels without zooming into the actual map.

Speaking of maps, I got to work a fun zoom project a few years ago: https://map.fieldmuseum.org/

We used https://openlayers.org/ and thought long and hard about how to best handle zooming and variable levels of information density & visual hierarchy. If you zoom all the way out, we just highlight where the building is relative to the surroundings. As you start to zoom in, we start to highlight major exhibitions and entrances. Then as you zoom in more, we start showing recommended paths, smaller exhibitions, etc. The label sizes try to scale up and down at each level, smoothly, in order to balance readability and density.

Eventually you can reach the max zoom level and the labels will just grow bigger and bigger, but the SVGs dynamically shrink so they remain pictograms and not just contextless-lines.

Then if you keep going, you eventually find microscopic easter eggs :)

The code is pretty jank (and abandoned), but it's FOSS vanilla JS/HTML/CSS, and the only dependency is on OpenLayers: https://github.com/arcataroger/openlayers_indoor_map

In order to display the GeoJSON features on a map, we will use OpenLayers, which is a very powerful open-source mapping library that is also very simple to use.

OpenLayers is available via the ol npm package, offering developers a powerful toolkit for creating sophisticated maps. Here is a JavaScript implementation that utilizes OpenLayers to showcase a map:

For web maps I'd strongly recommend using OpenLayers. While it's less convenient to get started with compared to the alternatives it's also much more feature-complete and you'll likely hit a ceiling in terms of functionality much later than you would with the others.
