    This component lets you work with the sensenet ECM Content Repository (create or manage content, execute queries, etc.) by providing a JavaScript client API for the main content operations. The library connects to a sensenet ECM portal's REST API, but hides the underlying HTTP requests. You can work with simple load or create Content operations in JavaScript, instead of having to construct ajax requests yourself.

    It also provides you the full sensenet Content Type system hierarchy through Typescript classes with all the fields defined in the CTDs and the Content Type schemas with FieldSettings so that you can manage Content easy on client-side knowing the related fields and their settings.

    Tested with the following Sense/Net Services version:

    Sense/Net Services

    Installation with node and npm

    To install the latest stable version run

    npm install --save sn-client-js


    Creating a Repository instance

    Your main entry point in this library is the Repository object. You can create an Instance by the following way:

    import { Repository } from 'sn-client-js';
    let repository = new Repository.SnRepository({
                RepositoryUrl: '',
                ODataToken: 'OData.svc',
                JwtTokenKeyTemplate: 'my-${tokenName}-token-for-${siteName}',
                JwtTokenPersist: 'expiration',
                DefaultSelect: ['DisplayName', 'Icon'],
                RequiredSelect: ['Id', 'Type', 'Path', 'Name'],
                DefaultMetadata: 'no',
                DefaultInlineCount: 'allpages',
                DefaultExpand: [],
                DefaultTop: 1000
    • RepositoryURL: The component will communicate with your repositoy using the following url. This will fall back to your window.location.href, if not specified. To enable your external app to send request against your sensenet portal change your Portal.settings. For further information about cross-origin resource sharing in sensenet check this article.
    • ODataToken: Check your Sense/Net portal's web.config and if the ODataServiceToken is set, you can configure it here for the client side.
    • JwtTokenKeyTemplate - This will be the template how your JWT tokens will be stored (in local/session storage or as a cookie). ${tokenName} will be replaced with the token's name ('access' or 'refresh'), ${siteName} will be replaced with your site's name
    • JwtTokenPersist - You can change how JWT Tokens should be persisted on the client, you can use 'session', whitch means the token will be invalidated on browser close, or 'expiration', in that case the token expiration property will be used (See JWT Token docs for further details)
    • DefaultSelect - These fields will be selected by default on each OData request. Can be a field, an array of fields or 'all'
    • RequiredSelect - These fields will always be included in the OData $select statement. Also can be a field, an array of fields or 'all'
    • DefaultMetadata - Default metadata value for OData requests. Can be 'full', 'minimal' or 'no'
    • DefaultInlineCount - Default inlinecount OData parameter. Can be 'allpages' or 'none'
    • DefaultExpand - Default fields to $expand, empty by default. Can be a field or an array of fields.
    • DefaultTop - Default value to the odata $top parameter

    Create, Save, Update

    You can create a new content instance in the following way:

    import { ContentTypes } from 'sn-client-js';
    let myTask = repository.CreateContent({
            Name: 'MyTask',
            Path: '/Root/MyWorkspace/MyTaskList'

    The content is not posted to the Reposiory yet, but you can bind it to a Create content form and update it's values like this:

    myTask.DueDate = "2017-09-12T12:00:00Z";

    You can always check if a specified content has been saved or not with the content.IsSaved property.

    If you've finished with the editing, you can Save it the following way:

        console.log('Task saved', task);
    }, error => console.error);

    Once the Task has been saved, you can continue working on the same object reference, update fields and call myTask.Save() again, the content will be updated in the sensenet ECM Repository.

    If you want to update a specified field only, you can do that with an optional Save() parameter (other changed properties will be ignored):

    myTask.Save({DisplayName: 'Updated Task Displayname'}).subscribe(task=>{
        console.log('Task saved', task);
    }, error => console.error)

    Load, Reload

    You can load a content instance from the repository by the following way:

    //by Path
        console.log('Task loaded', loadedTask);
    }, error => console.error);
    //or by Id
    let myTaskId = 12345
        console.log('Task loaded', loadedTask);
    }, error => console.error);
    //you can also specify which fields you want to load or expand
    repository.Load(myTaskId, {
        select: ['Name', 'DisplayName'],
        expand: 'Owner'
    }).subscribe(loadedTask => {
        console.log('Task loaded', loadedTask);
    }, error => console.error);

    If you load or reload the same content from the same repository, you will get the same object reference

    If you use Schema definition and you need to reload a content for a specified action (can be 'view' or 'edit' for now) you can do that with:

        console.log('Task reloaded', reloadedTask);
    }, error => console.error)

    If you want to reload only specific fields or references, you can do that in the following way:

    myTask.ReloadFields('Owner', 'Name', 'ModifiedBy').subscribe(reloadedTask=>{
        console.log('Fields loaded', reloadedTask);
    }, error => console.error)

    Reference fields

    You can query reference fields like the following:

    myTask.CreatedBy.GetContent().subscribe(createdBy => {
        console.log('Task is created by', createdBy);

    Reference fields are loaded lazily. This means that if their value isn't loaded yet, it will make an additional HTTP request. If you know exactly what reference fields will be used, call content.Reload('view' | 'edit') or content.ReloadFields(...fields) to speed things up.


    If you want to delete a content permanently (or just move it to the Trash folder), you can simply call:

    let permanently = false;
        console.log('Moved to trash.');
    }, err=> console.error);

    Tracking changes

    There are several methods to track the state of content instances

    • content.IsSaved - Shows if the content is just created or is saved to the Repository
    • content.IsDirty - Indicates if some of its fields has changed
    • content.IsValid - Indicates if all complusory fields has been filled
    • content.SavedFields - Returns an object with the last saved fields
    • content.GetChanges() - Returns an object with the changed fields and their new values

    If the content is partially loaded, only their loaded fields or references will be tracked.

    Hierarchical content comparison

    As sensenet ECM stores content in a tree-based repository, there are some methods for hierarchical comparison between content. These methods are:

    • content.IsParentOf(childContent: Content): boolean
    • content.IsChildOf(parentContent: Content): boolean
    • content.IsAncestorOf(descendantContent: Content): boolean
    • content.IsDescendantOf(ancestorContent: Content): boolean

    Repository events

    There are some Event Observables on the Repository level which you can subscribe for tracking changes. You can find them on the repository.Events namespace. They are:

    • OnContentCreated
    • OnContentCreateFailed
    • OnContentModified
    • OnContentModificationFailed
    • OnContentLoaded
    • OnContentDeleted
    • OnContentDeleteFailed
    • OnContentMoved
    • OnContentMoveFailed
    • OnCustomActionExecuted
    • OnCustomActionFailed

    Content Queries

    You can run queries from a repository instance or from a content instance. There is a fluent API for creating type safe and valid Content Queries

    const query = repository.CreateQuery(q => 
            .Equals('DisplayName', 'a*')
        .subscribe(res => {
         console.log('Folders count: ', res.Count);
         console.log('Folders: ', res.Result);

    Get the Schema of the given ContentType

    let schema = Content.GetSchema(ContentTypes.GenericContent);

    Read Collection data

    import { Collection } from 'sn-client-js';
    let collection = new Collection([], repository, ContentTypes.Task);
    let fetchContent = collection.Read('/NewsDemo/External', { select: 'all' }); //gets the list of  the external Articles with their Id, Type and DisplayName fields.
        .map(response => response.d.results)
         next: response => {
          //do something with the response
          error: error => console.error('something wrong occurred: ' + error),
          complete: () => console.log('done'),

    Delete a Content from a Collection

    let deleteContent = myCollection.Remove(3);
            next: response => {
                //do something after delete
            error: error => console.error('something wrong occurred: ' + error),
            complete: () => console.log('done'),
