QGIS2Web: Publish a Web Map from QGIS
What is QGIS2Web?
QGIS2Web takes your desktop GIS so you publish it interactively for the web. If you have your own server, then this plugin creates all the supporting files you need without any server-side software installed.
Not only does it replicate the symbology and cartographic aspects of your current QGIS Desktop, but you have the option to export a web map to either OpenLayers, Leaflet, or Mapbox GL JS.
Additionally, you can set the web map to have popups, clusters, and a variety of properties and widgets to make them more appealing to your audience.

In addition, there are several widgets available as well to add to your web map. For example, this includes everything from a measuring tool, layer search, layer list, address search, show pop-ups, and highlight on hover.
Once you’re OK with all the settings, click “Export”. Next, it will build a web map package to the folder location you select. After it finishes exporting, it packages all the contents and settings you selected into a folder.
The folder contains all of the supporting files and folders. For example, it also contains any images, layers, resources, and styles. But it also has an index file, which has all of the HTML that gets presented on the screen.
If you double-click the index.html file, this will open your browser and display everything from your setup from the QGIS2Web plugin. From here, you will have to upload the contents from QGIS2Web into your web server so the public can view your new web map.
