Gantt - API Enhancements and PDF Export

We continue to address requests regarding recently released components such as Gantt and Diagram. Most requests are related to component customization. In 2021, we’ll add the following customization capabilities to our Gantt component:

  • Expand/collapse tasks programmatically
  • Show/hide dependencies via a toolbox item or programmatically
  • Specify initial date range to display
  • Support sorting by column

Diagram – API Enhancements

We expect to ship the following new DevExtreme Diagram customization features in 2021:

  • Customize item appearance via custom CSS styles
  • Extend diagram item events with new ‘onHover’ and ‘onLeave’ events

File Manager – API Enhancements

We will extend the DevExtreme File Manager and make it more customizable with the following new APIs:

  • Add events to precisely control file/folder operations (folder creation, file uploading, moving, deleting, etc.)
  • Wrap long file names in the File Manager’s detail view
  • Customize icons in the Folder Tree

Tree Shaking & Code Splitting In development

A lot of work has been done in the regard to better Tree Shaking, but much work remains to be completed for better Code Splitting. Last year we reworked DevExtreme modular system to deliver ES6 modules in DevExtreme NPM packages. The final “mile” was unexpectedly long – as issues prevented us from shipping ES6 modules inside v20.2.

Note, ES6 modules make it technically possible to efficiently tree shake code. Unfortunately, this not enough for efficient bungle/chunk size optimization. Modules themselves need to be small and independent from one another. Large components should not be monoliths. That’s our goal for 2021 - make existing modules smaller and more independent - and split large monolith components into separate modules. We don't expect to finish everything in this regard this year, but we expect to eliminate the most problematic issues.

Material Design Enhancements In development

The Google team constantly updates its Material Design Guidelines. We plan to incorporate relevant changes and previously planned Editor Label Animations.

“Nativeness” Under research

The JavaScript world evolves rapidly. As such, we must fulfill user demand whenever a popular JS framework appears or an existing framework receives a major update. While we want to ship products as soon as possible, we also want to deliver products of the highest possible quality.

A few years ago, we decided to wrap existing JS components for Angular, React and Vue so you can leverage our 70+ JavaScript components with your framework of choice immediately. Now we want to go even further and eliminate the perceived disadvantages of ‘wrappers’. We are still at the research stage and we’ll be posting updates on this particular topic once we have something relevant to share.

As it relates to “nativeness”, we have three specific objectives for DevExtreme:

Native API & Lifecycle

Our current API allows you to implement almost any usage scenario, but in some instance, our API may not “feel” native. Sometimes the API requires direct DOM access or instance method calls instead of declarative bindings. Sometimes you need to use DevExtreme-specific events instead of the target framework’s lifecycle events. We want to address all these issues and deliver native declarative APIs and support native lifecycles.

Native Data Binding

DevExtreme ships with a powerful data layer that encapsulates all the complexity of client-side data processing and remote HTTP request handling. This notwithstanding, in some instance, you may need to bind components directly to your local application state. This state can be represented by static arrays, observable arrays, Redux or NgRx store, etc. We plan to improve the developer experience in this regard and deliver a straightforward solution to address these usage scenarios.

Native Rendering

Each JS framework comes with its own philosophy and core technical foundation. React and Vue are based on Virtual DOM, Vue and Angular use observables, etc. Multi-thread rendering via Web Workers is on the horizon. All these techniques offer benefits - from better performance to server-side rendering support. While DevExtreme wrappers leverage some of these benefits, we can do more. We are researching ways to deliver all of them via a fully native internal component architecture. We’ve already got some promising results in this regard, but still have some core issues to address before we can share our solution with you.

TypeScript In development

Another key area of focus will be TypeScript support. Thanks to your feedback, we know what to do and which use cases to address. First, we want to replace ‘any’ type with specific types wherever possible. Second, we expect to make event arguments strongly typed and extract these types/interfaces so you can use them in your projects.


This year we plan to allocate more resources to documentation. The mix of technologies on our website is confusing, so we plan to have dedicated websites for each JS framework we support. For instance, if you target React, you won’t be distracted with Angular or ASP.NET-related examples or documentation topics. Additional examples and demos for each framework are also on the horizon.
