Node Service
Gets Alfresco Repository node metadata and creates nodes with metadata.
This service cannot be used to create nodes with content.
Importing
import { NodeService } from '@alfresco/adf-core';
export class SomePageComponent implements OnInit {
constructor(private nodeService: NodeService) {
}
Methods
getNodeMetadata(nodeId: string): Observable<NodeMetadata>
Get the metadata and type for passed in node ID (e.g. 3062d73b-fe47-4040-89d2-79efae63869c):
// Get the node reference from somewhere...
const nodeId = '3062d73b-fe47-4040-89d2-79efae63869c';
this.nodeService2.getNodeMetadata(nodeId).subscribe(data => {
const nodeMetadata = data.metadata;
const nodeType = data.nodeType;
console.log('nodeMetadata', nodeMetadata);
console.log('nodeType', nodeType);
}, error => {
console.log('Error: ', error);
});
The metadata response doesn't include the cm:auditable properties (i.e. created, creator, modified, modifier, last access)
or the name of the node (i.e. cm:name).
The metadata response looks like in this example:
author: "Martin"
description: "Installation guide for Alfresco 3.3 on Linux"
lastThumbnailModification: "doclib:1505900632400"
title: "Install 3.3 Linux"
versionLabel: "1.0"
versionType: "MAJOR"
Note that the properties are missing namespace prefix. The nodeType response will be returned with namespace prefix,
such as cm:content.
Executing this method on a folder node returns no metadata, just the type.
createNode(name: string, nodeType: string, properties: any, path: string): Observable<any>
Creates a node in the Alfresco Repository with passed in name, nodeType, and metadata properties.
It will be created in the folder path that is passed in.
const nodePath = '/Guest Home';
const nodeName = 'someFolder';
const nodeType = 'cm:folder';
const properties = {
'cm:title': 'Some title',
'cm:description': 'Some description'
};
this.nodeService2.createNode(nodeName, nodeType, properties, nodePath).subscribe(nodeInfo => {
console.log('New Node info: ', nodeInfo);
}, error => {
console.log('Error: ', error);
});
Note that the path property should not include the /Company Home bit.
The response includes all metadata about the new node:

createNodeMetadata(nodeType: string, nameSpace: any, data: any, path: string, name?: string): Observable<any>
This is a convenience method if your property list is missing namespace prefix for property names.
The namespace prefix can then be supplied separately and this method will prepend it automatically.
This method calls the createNode method internally:
const nodePath = '/Guest Home';
const nodeName = 'someOtherFolder';
const nodeType = 'cm:folder';
const propNamespacePrefix = 'cm';
const properties = {
'title': 'Some title',
'description': 'Some description'
};
this.nodeService2.createNodeMetadata(nodeType, propNamespacePrefix, properties, nodePath, nodeName).subscribe(nodeInfo => {
console.log('New Node info: ', nodeInfo);
}, error => {
console.log('Error: ', error);
});
See the createNode method for information about the response object.
