Reference

This page lists each setting path, environment variable override, default, and valid values.

Config file metadata

`version`

Table 1. version
Environment variable	`NES_version`
Description	Schema version for this Enterprise Studio configuration file.
Default value	`1`

`kind`

Table 2. kind
Environment variable	`NES_kind`
Description	Identifies the file as an Enterprise Studio configuration.
Valid values	`neo4j-enterprise-studio-config`
Default value	`neo4j-enterprise-studio-config`

Asset storage settings

`assetStore.default.uri`

Table 3. assetStore.default.uri
Environment variable	`NES_assetStore_default_uri`
Description	Neo4j deployment URI of the tools asset database (for example `neo4j://localhost:7687`).
Default value	`null`

`assetStore.default.database`

Table 4. assetStore.default.database
Environment variable	`NES_assetStore_default_database`
Description	Name of the database used for tool asset storage.

`assetStore.default.authentication`

Table 5. assetStore.default.authentication
Description	Service-account authentication method the server uses to connect to the asset storage DBMS. Configure exactly one method block: `basic`, `oidc`, or `none`. When `oidc` is set, Enterprise Studio obtains a bearer token from an external identity provider via the OAuth 2.0 client-credentials grant and uses it to authenticate to the storage database. The `oidc` sub-block fields below configure the IdP request, and the Neo4j DBMS must be configured with a matching OIDC provider that trusts the IdP. Specify `none` as an empty block (`none: {}`) to connect without authentication.

Table 6. assetStore.default.authentication.basic.username
Environment variable	`NES_assetStore_default_authentication_basic_username`
Description	Service account username for the asset storage connection.
Default value	`null`

`assetStore.default.authentication.basic.password`

Environment variable	`NES_assetStore_default_authentication_basic_password`
Description	Service account password for the asset storage connection.
Default value	`null`

`assetStore.default.authentication.oidc.tokenUrl`

Table 8. assetStore.default.authentication.oidc.tokenUrl
Environment variable	`NES_assetStore_default_authentication_oidc_tokenUrl`
Description	OAuth 2.0 token endpoint of the identity provider, used when the `oidc` method is configured. Must use the `https` scheme. For Microsoft Entra ID this is `https://login.microsoftonline.com/<tenant-id>/oauth2/v2.0/token`; for Keycloak it is `https://<host>/realms/<realm>/protocol/openid-connect/token`.
Default value	`null`

`assetStore.default.authentication.oidc.clientId`

Table 9. assetStore.default.authentication.oidc.clientId

Table 11. assetStore.default.authentication.oidc.scopes
Environment variable	`NES_assetStore_default_authentication_oidc_scopes`
Description	List of OAuth 2.0 scopes requested when fetching the token. Provider-specific; for Microsoft Entra ID set this to `[api://<neo4j-app-id>/.default]`.

`neo4jDeployments.<deployment-id>.uri`

Table 14. neo4jDeployments.deployment-id.uri
Environment variable	`NES_neo4jDeployments_<deployment-id>_uri`
Description	Neo4j deployment URI of the main database used by the server. When `directClientQuery.enabled` is `false`, the URI must use the `http` or `https` scheme, since Enterprise Studio proxies all queries over HTTP.

Table 19. neo4jDeployments.deployment-id.authorization.roleMapping
Environment variable	`NES_neo4jDeployments_<deployment-id>_authorization_roleMapping`
Description	Role mapping that grants Enterprise Studio roles to Neo4j database users and roles. In _config.yaml\_, define `roleMapping` as a YAML list; each entry has a `role` (`studioAdmin` or `studioCreator`) and a `members` list, where each member has a `kind` (`databaseUser` or `databaseRole`) and a `name`. When overriding with an environment variable, set `NES_neo4jDeployments_<deployment-id>_authorization_roleMapping` to the full `roleMapping` array as a JSON string. There are no separate environment variables for individual `members` or `role` values. When omitted, the role mapping defaults to granting `studioAdmin` to the Neo4j `admin` role (`databaseRole:admin`).

Valid values	`true` or `false`
Default value	`true`

To serve a custom basemap instead of the default Neo4j PMTiles provider, configure mapTiles.customTilesProvider. The block has three parts: format (the tile data shape), upstream (where to fetch the tiles — exactly one of http or file), and output (what the proxy returns to the browser). When the whole block is omitted, the bundled Neo4j PMTiles dataset is served.

Table 29. mapTiles.customTilesProvider.upstream.http.url
Environment variable	`NES_mapTiles_customTilesProvider_upstream_http_url`
Description	URL of the upstream tile provider, proxied through the Enterprise Studio server. For `raster` format, the URL must contain the placeholder template `{z}/{x}/{y}`. For `pmtiles` format, it must be a single-file URL with no placeholders. Set exactly one of `upstream.http` or `upstream.file`.
Default value	`null`
