Volto Maplibre block (@codesyntax/volto-maplibre-block)

A new add-on for Volto

Introduction

Volto block and component to render maps using the maplibre JS library, which is a fork of Mapbox GL 1.x.

To do so we use the react-map-gl library, which supports both maplibre and Mapblox GL

I have heavily based this block on volto-leaflet-block.

The point is that Leaflet has several issues with SSR and it is not ready to work on SSR and will not be ready to do so. So instead of doing ugly hacks, I have decided to create my own map block.

Features

A generic Map component, that can be used in your Volto developments.
A Map block, that allows some basic configuration (used tiles, map center, zoom, and a list of markers (title, link and icon))

Customization

You can add extra map layers, or remove existing ones, tweaking the tileLayers property of the block:

const applyConfig = (config) => {
  // Own blocks
  config.blocks.blocksConfig['mapLibreBlock']['tileLayers'] = [
      {
        id: 'osm',
        name: 'OpenStreetMap',
        type: 'raster',
        urls: [
          'https://a.tile.openstreetmap.org/{z}/{x}/{y}.png',
          'https://b.tile.openstreetmap.org/{z}/{x}/{y}.png',
          'https://c.tile.openstreetmap.org/{z}/{x}/{y}.png',
        ],
        tileSize: 256,
        attribution:
          '&copy; OpenStreetMap Contributors | Kartendarstellung &copy; OpenTopoMap (CC-BY-SA)',
        maxzoom: 19,
      },
    ]


  return config;
};

Installation

To install your project, you must choose the method appropriate to your version of Volto.

Volto 17 and earlier

Create a new Volto project (you can skip this step if you already have one):

npm install -g yo @plone/generator-volto
yo @plone/volto my-volto-project --addon @codesyntax/volto-maplibre-block
cd my-volto-project

Add @codesyntax/volto-maplibre-block to your package.json:

"addons": [
    "@codesyntax/volto-maplibre-block"
],

"dependencies": {
    "@codesyntax/volto-maplibre-block": "*"
}

Download and install the new add-on by running:

yarn install

Start volto with:

yarn start

Volto 18 and later

Add @codesyntax/volto-maplibre-block to your package.json:

"dependencies": {
    "@codesyntax/volto-maplibre-block": "*"
}

Add @codesyntax/volto-maplibre-block to your volto.config.js:

const addons = ['@codesyntax/volto-maplibre-block'];

If this package provides a Volto theme, and you want to activate it, then add the following to your volto.config.js:

const theme = '@codesyntax/volto-maplibre-block';

Test installation

Development

The development of this add-on is done in isolation using a new approach using pnpm workspaces and latest mrs-developer and other Volto core improvements. For this reason, it only works with pnpm and Volto 18 (currently in alpha).
