MapStore Framework - Frontend Only Project (Experimental)

This session focus on the use of MapStore as a frontend framework where the GeoStore backend is excluded. This approach could be useful when we need to connect MapStore to a different backend or when we want create a viewer/dashboard that extract data from static configuration files.

The exercise in this session will allow to create a map viewer using an experimental project creation process, the result can be viewed here. Some useful links:

Install a MapStore project frontend only

navigate in your workspace folder and run the creation script using npx

npx @mapstore/project create

the script will prompt some options before to create and these are the value selected for this custom project

- Name of project (default mapstore-project): static-map
- Include backend (yes/no default yes): no
- Optional features (printing, ldap):
- Run npm install after creation setup (yes/no default yes): no

navigate inside the static-map folder

cd static-map/

change the mapstore dependencies inside the package.json to point to the latest stable branch instead of master

touch package.json

replace the mapstore dependencies with the needed branch version

"dependencies": {
    "mapstore": "git+<branch|tag>"

add configuration to package.json to target specific folder of this project instead of the default one

"mapstore": {
    "apps": [
    "html": [
    "themes": [

remove all the default apps inside the static-map/js/apps directory

create a new entry called static-map/js/apps/static-map.js with the following content

export default {

install all the dependencies with

npm install


Run the application with the following command

npm start

app runs at http://localhost:8081/

npm install is needed only once at first setup or if the dependencies have been updated. If the installation does not solve correctly the dependencies use npm install –legacy-peer-deps (eg latest version of node/npm)

Build the app

You can run the build script to generate the client static application in the dist folder


the compiled app will be copied to dist/ folder

Best practices

Here some suggestions on how to improve the setup of a custom project:

  • ensure all the configuration path are initialized correctly. An example are the symbols for annotation and their location in the repository.
  • add a custom plugins definition and import only the plugins used by the app. This will reduce the size of final js bundle
  • use the alias @mapstore/framework/ to have access to the components inside the folder MapStore2/web/client/ of MapStore
  • use the alias @js/ to have access to the components inside the js folder of the custom project
  • use the options available in the main entries to initialize the state of the app with particular conditions (an example is the security state)
