ECM

A complete list of all the ECM methods is available here: Content API. Below you can find some common examples.

Get Node Content

NodesApi.getFileContent(nodeId, opts)

Returns the file content of the node with identifier nodeId.

Example

const fs = require('fs');

const alfrescoApi = new AlfrescoApi(/*...*/);
const nodesApi = new NodesApi(alfrescoApi);
const nodeId = '80a94ac8-3ece-47ad-864e-5d939424c47c';

nodesApi.getNodeContent(nodeId).then(
    (data) => {
        fs.writeFile('./test/grass.jpg', data, (error) => {
            if (error) {
                console.error(error);
                return;
            }
            console.log('The file was saved!');
        });
    }, 
    (error) => {
        console.error(error);
    });

Get a Node Info

NodesApi.getNodeInfo(nodeId, opts)

Get information for the File/Folder with the identifier nodeId. You can also use one of these well-known aliases: -my-, -shared- or -root- as nodeId value.

Example

const alfrescoApi = new AlfrescoApi(/*...*/);
const nodeId = '80a94ac8-3ece-47ad-864e-5d939424c47c';
const nodesApi = new NodesApi(alfrescoApi);

nodesApi.getNode(nodeId, opts).then( 
    (nodeEntry) => {
        console.log('This is the name' + nodeEntry.entry.name );
    },
    (error) => {
        console.log('This node does not exist');
    });

Get Folder Children Info

NodesApi.getNodeChildren(fileOrFolderId, opts)

Minimal information for each child is returned by default.

You can use the include parameter to return additional information. returns a promise with the Info about the children of the node if resolved and {error} if rejected.

You can also use one of these well-known aliases: -my-, -shared- or -root- as nodeId value.

Example:

const alfrescoApi = new AlfrescoApi(/*...*/);
const nodeId = '80a94ac8-3ece-47ad-864e-5d939424c47c';
const nodesApi = new NodesApi(alfrescoApi);

nodesApi.listNodeChildren(nodeId, opts).then( 
    (data) => {
        console.log(
            'The number of children in this folder are ' + data.list.pagination.count
        );
    },
    (error) => {
        console.log('This node does not exist');
    });

Create Folder

NodesApi.addNode(nodeId, nodeBody, opts)

Returns a promise that is resolved if the folder is created and {error} if rejected.

You can also use one of these well-known aliases: -my-, -shared- or -root- as nodeId value.

Example

const alfrescoApi = new AlfrescoApi(/*...*/);
const nodesApi = new NodesApi(alfrescoApi);

const nodeBody = {
    'name': 'newFolderName',
    'nodeType': 'cm:folder',
    'relativePath': relativePath
};

nodesApi.addNode('-root-', nodeBody).then( 
    (data) => {
        console.log('The folder is created in root');
    },
    (error) => {    
        console.log('Error in creation of this folder or folder already exist' + error);
    });

const alfrescoApi = new AlfrescoApi(/*...*/);
const nodesApi = new NodesApi(alfrescoApi);

const nodeBody = {
    'name': 'newFolderName',
    'nodeType': 'cm:folder',
    'relativePath': 'folderA/folderB'
};

nodesApi.addNode('-root-', nodeBody).then( 
    (data) => {
        console.log('The folder is created in  folderA/folderB from root');
    },
    (error) => {    
        console.log('Error in creation of this folder or folder already exist' + error);
    });

const alfrescoApi = new AlfrescoApi(/*...*/);
const nodesApi = new NodesApi(alfrescoApi);

const nodeBody = {
    'name': 'newFolderName',
    'nodeType': 'cm:folder',
    'relativePath': 'folderA/folderB'
};
const parentFolder = '80a94ac8-3ece-47ad-864e-5d939424c47c'

nodesApi.addNode(parentFolder, nodeBody).then( 
    (data) => {
        console.log('The folder is created in  folderA/folderB from parentFolder:' + parentFolder);
    },
    (error) => {    
        console.log('Error in creation of this folder or folder already exist' + error);
    });

CreateFolder With Auto Rename

const alfrescoApi = new AlfrescoApi(/*...*/);
const nodesApi = new NodesApi(this.alfrescoApi);

const nodeBody = {
    name: 'newFolderName',
    nodeType: 'cm:folder',
    autoRename: true,
    relativePath: 'folderA/folderB'
};

nodesApi.addNode('-root-', nodeBody).then( 
    (data) => {
        console.log('The folder is created in root');
    },
    (error) => {    
        console.log('Error in creation of this folder or folder already exist' + error);
    });

Upload File

UploadApi.uploadFile(fileDefinition, relativePath, nodeId, nodeBody, opts)

Returns a promise that is resolved if the file is successful uploaded and {error} if rejected.

The fileDefinition provides information about files and allows JavaScript to access their content.

Web

File Definition are generally retrieved from a FileList object returned as a result of a user selecting files using the <input> element

Node

File Definition are generally retrieved from a read stream

const alfrescoApi = new AlfrescoApi(/*...*/);
const fs = require('fs');

const fileToUpload = fs.createReadStream('./folderA/folderB/newFile.txt');
const uploadApi = new UploadApi(alfrescoApi);

uploadApi.uploadFile(fileToUpload).then(
    () => {
        console.log('File Uploaded in the root');
    }, 
    (error) => {
        console.log('Error during the upload' + error);
    });

uploadApi.uploadFile(fileToUpload, null, null, null, { autoRename: true })
    .then(() => {
        console.log('File Uploaded in the root');
    }, (error) => {
        console.log('Error during the upload' + error);
    });

uploadApi.uploadFile(fileToUpload, 'folderX/folderY/folderZ')
    .then(() => {
        console.log('File Uploaded in the from root folderX/folderY/folderZ');
    }, (error) => {
        console.log('Error during the upload' + error);
    });

const parentFolder = '80a94ac8-3ece-47ad-864e-5d939424c47c';

uploadApi.uploadFile(fileToUpload, 'folderX/folderY/folderZ', parentFolder )
    .then(() => {
        console.log('File Uploaded in the from parentFolder ' + parentFolder + ' n folderX/folderY/folderZ');
    }, (error) => {
        console.log('Error during the upload' + error);
    });

The default behaviour of the Upload API will not create any thumbnail.

In order to create a thumbnail you have to perform to pass the parameter {renditions: 'doclib'} as in the example below. This parameter will basically perform also a call to the Rendition API.

For more information about the Rendition API :

• Rendition API
• Rendition service Wiki

const alfrescoApi = new AlfrescoApi(/*...*/);
const fs = require('fs');

const fileToUpload = fs.createReadStream('./folderA/folderB/newFile.txt');
const uploadApi = new UploadApi(alfrescoApi);

uploadApi.uploadFile(fileToUpload, null, null, null, {renditions: 'doclib'})
    .then(() => {
        console.log('File Uploaded in the root');
    }, (error) => {
        console.log('Error during the upload' + error);
    });

To abort a file uploading:

const alfrescoApi = new AlfrescoApi(/*...*/);
const fs = require('fs');

const fileToUpload = fs.createReadStream('./folderA/folderB/newFile.txt');
const uploadApi = new UploadApi(alfrescoApi);

const promiseUpload = uploadApi.uploadFile(fileToUpload)
    .once('abort', function () {
        console.log('File Uploaded aborted');
    });

promiseUpload.abort();

Upload File Events

The uploadFile is also an EventEmitter which you can register to listen to any of the following event types:

• progress
• success
• abort
• error
• unauthorized

const alfrescoApi = new AlfrescoApi(/*...*/);
const fs = require('fs');

const fileToUpload = fs.createReadStream('./folderA/folderB/newFile.txt');
const uploadApi = new UploadApi(alfrescoApi);

uploadApi.uploadFile(fileToUpload)
    .on('progress', (progress) => {
        console.log( 'Total :' + progress.total );
        console.log( 'Loaded :' + progress.loaded );
        console.log( 'Percent :' + progress.percent );
    })
    .on('success', () => {
        console.log( 'Your File is uploaded');
    })
    .on('abort', () => {
        console.log( 'Upload Aborted');
    })
    .on('error', () => {
        console.log( 'Error during the upload');
    })
    .on('unauthorized', () => {
        console.log('You are unauthorized');
    })

Delete a Node

NodesApi.deleteNode(fileOrFolderId, opts)

Delete File/Folder with the identifier nodeId, if the nodeId is a folder, then its children are also deleted. Deleted nodes are moved to the trash bin, and it is still possible to recover them.

const alfrescoApi = new AlfrescoApi(/*...*/);
const fileOrFolderId = '80a94ac8-3ece-47ad-864e-5d939424c47c';
const nodesApi = new NodesApi(alfrescoApi);

nodesApi.deleteNode(fileOrFolderId).then(
    (data) => {
        console.log('The file/folder is deleted');
    }, 
    (error) => {
        console.log('This node does not exist');
    });

Delete a Node Permanently

NodesApi.deleteNode(fileOrFolderId, { permanent: true })

Delete File/Folder with the identifier nodeId, if the nodeId is a folder, then its children are also deleted. It will not be possible to recover the files after this call.

const alfrescoApi = new AlfrescoApi(/*...*/);
const fileOrFolderId = '80a94ac8-3ece-47ad-864e-5d939424c47c';
const nodesApi = new NodesApi(alfrescoApi);

nodesApi.deleteNode(fileOrFolderId, { permanent: true }).then(
    (data) => {
        console.log('The file/folder is deleted');
    }, 
    (error) => {
        console.log('This node does not exist');
    });

Get Thumbnail Url

ContentApi.getDocumentThumbnailUrl(documentId)

Example

const alfrescoApi = new AlfrescoApi(/*...*/);
const contentApi = new ContentApi(alfrescoApi);

const thumbnailUrl = contentApi.getDocumentThumbnailUrl('1a0b110f-1e09-4ca2-b367-fe25e4964a4');

Get Preview Url

ContentApi.getDocumentPreviewUrl(documentId)

Example

const alfrescoApi = new AlfrescoApi(/*...*/);
const contentApi = new ContentApi(alfrescoApi);

const previewUrl = contentApi.getDocumentPreviewUrl('1a0b110f-1e09-4ca2-b367-fe25e4964a4');

Get Content Url

ContentApi.getContentUrl(documentId)

Example

const alfrescoApi = new AlfrescoApi(/*...*/);
const contentApi = new ContentApi(alfrescoApi);

const contentUrl = contentApi.getContentUrl('1a0b110f-1e09-4ca2-b367-fe25e4964a4');

Custom WebScript Calls

For mor information about web scripts read the Wiki and the Wiki with Web ScriptsExamples

executeWebScript(httpMethod, scriptPath, scriptArgs, contextRoot, servicePath, postBody)

Anatomy of a Web Script URI:

http(s)://(host):(port)/(contextPath)/(servicePath)/(scriptPath)?(scriptArgs)

A Web Script is simply a service bound to a URI which responds to HTTP methods such as GET, POST, PUT and DELETE. While using the same underlying code, there are broadly two kinds of Web Scripts.

Parameters

Name	Description
httpMethod	possible value GET, POST, PUT and DELETE
scriptPath	path to Web Script (as defined by Web Script)
scriptArgs	arguments to pass to Web Script
contextRoot	path where application is deployed default value 'alfresco'
servicePath	path where Web Script service is mapped default value 'service'
postBody	post body

const alfrescoApi = new AlfrescoApi(/*...*/);
const webscriptApi = new WebscriptApi(alfrescoApi);

// Call a GET on a Web Scripts available at the following URIs: http://127.0.01:8080/alfresco/service/mytasks

webscriptApi.executeWebScript('GET', 'mytasks').then( 
    (data) => {
        console.log('Data received form http://127.0.01:8080/alfresco/service/mytasks' + data);
    },  
    (error) => {   
        console.log('Error' + error);
    });

// Call a GET on a Web Scripts available at the following URIs: http://127.0.01:8080/share/service/mytasks

webscriptApi.executeWebScript('GET', 'mytasks', null, 'share').then( 
    (data)=> {
        console.log('Data received form http://127.0.01:8080/share/service/mytasks' + data);
    },  
    (error)=> {
        console.log('Error' + error);
    });

// Call a GET on a Web Scripts available at the following URIs: http://127.0.01:8080/share/differentServiceSlug/mytasks

webscriptApi.executeWebScript('GET', 'mytasks', null, 'share', 'differentServiceSlug').then( 
    (data)=> {
        console.log('Data received form http://127.0.01:8080/share/differentServiceSlug/mytasks' + data);
    },  
    (error) => {
        console.log('Error' + error);
    });
