How to fetch children of node via webroot path in Gentics Mesh?

Unfortunately it's not possible to do so with just the webroot. However, there're other ways to accomplish it:

• Use the GraphQL-Enpoint by using this query for example:

  query childrenByWebroot($path: String) {
   node(path: $path) {
     uuid
     children {
       elements {
         uuid
       }
     }
    }
  }
  

  This will just load all UUIDs of the children and the parent. For more functionality, check the Docs of GraphQL for more information.

• Load the Node from the webroot first and and then load the children via the Children-Endpoint: /api/v1/<project>/nodes/<uuid>/children

• Search for Nodes which have the webroot-element as parent. This allows you to filter the content more clearly if it is required:

  {
    "query": {
      "bool": {
        "must": [
          {
            "term": {
              "parentNode.uuid": "<uuid>"
            },
            // ... Other checks
          }
        ]
      }
    }
  }
  

There is currently no way to load the children of a node via REST using a single request. You can however load the node of the path. Use the uuid of that node and load the children via /api/v1/:projectName/nodes/:nodeUuid/children

A much more elegant approach however would be to use the following graphql query. I highly recommend this option since it is more efficient when handling large datasets.

Background: Computing the totalCount / totalPage size is costly and you can avoid this by using hasPreviousPage and hasNextPage.

You can use the following graphql query:

query ($path: String) {
  node(path: $path) {
    children(perPage: 5) {
      hasNextPage
      hasPreviousPage
      currentPage
      elements {
        uuid
        fields {
          ... on vehicleImage {
            name
          }
        }
      }
    }
  }
}

Query variables:

{
  "path": "/images"
}
