Install Neo4j plugin

Install the Neo4j plugin

Install the Neo4j plugin using the Datashare CLI so that users can access it from the frontend:

docker compose exec datashare_web /entrypoint.sh \
  --mode CLI \
  --pluginInstall datashare-plugin-neo4j-graph-widget 

Installing the plugin installs the datashare-plugin-neo4j-graph-widget plugin inside /home/datashare/plugings and will also install the datashare-extension-neo4j backend extension inside /home/datashare/extensions. These locations can be changed by updating the docker-compose.yml.

Configure the Neo4j extension

Update the docker-compose.yml to reflect your Neo4j docker service settings.

...
services:
    datashare_web:
      ...
      environment:
        - DS_DOCKER_NEO4J_HOST=neo4j
        - DS_DOCKER_NEO4J_PORT=7687
        - DS_DOCKER_NEO4J_SINGLE_PROJECT=secret-project  # This is for community edition only

If your choose a different Neo4j user or set a password for your Neo4j user make sure to also set DS_DOCKER_NEO4J_USER and DS_DOCKER_NEO4J_PASSWORD.

When running Neo4j Community Edition, set the DS_DOCKER_NEO4J_SINGLE_PROJECT value. In community edition, the Neo4j DBMS is restricted to a single database. Since Datashare supports multiple projects, you must set the DS_DOCKER_NEO4J_SINGLE_PROJECT with the name of the project which will use Neo4j plugin. Other projects won't be able to use the Neo4j plugin.

Restart Datasahre

After installing the plugin a restart might be needed for the plugin to display:

docker compose restart datashare_web
