Huawei DevEco 3.0 Beta 1: Everything you need to know about HarmonyOS 3.0 development IDE



Huawei DevEco Studio

At HDC 2021, Huawei showcased the HarmonyOS 3.0.0 developer preview. The Chinese tech maker also displayed some of the major attributes of IDE tools DevEco Studio 3.0 and DevEco Device Tool 3.0. In addition, it was upgraded to version 3.0 Beta 1.

This platform is developed by Huawei to allow more and more developers to connect with HarmonyOS and let them modify the software accordingly. Moreover, it’s a kind of attempt for promoting the distributive capabilities of the system software and enlarge the application area.

In addition, the company timely provides more support and function to this platform to maintain a seamless work on it. Furthermore, extra features and support encourage the developers to expand their boundaries and try something beyond imagination.

Below we are going to learn about the new Huawei HarmonyOS DevEco 3.0 Beta 1-


Speaking of which, Huawei DevEco Studio is a one-stop integrated development environment (IDE) for developing HarmonyOS applications and atomic services. With its help, developers are able to perform functions such as project template creation, development, compilation, debugging, and release. Now the beta 1 version has been released, so let’s take a look at the features.

ArkUI 3.0 framework Support

The ArkUI 3.0 is known as the set of declarative UI development frameworks for building the HarmonyOS application interface. The developers will be able to work with efficiency, thanks to the help of its capabilities such as a minimalist UI information description grammar, rich UI components and dynamic effects, and real-time interface preview.

It mainly provides two functions that include-

Bidirectional speed preview:


The 3.0 Beta1 version provides a two-way preview function, two-way association code and built-in components of the preview interface, and linkage between the code editor, the UI interface, and the component tree.

For instance, if a component is selected on the UI interface, the corresponding component in the component tree will be selected, and the corresponding code block in the editor will be highlighted. Similarly, when you click on the code or component tree, it will also be highlighted in the interface.

However, if the developer does not change the page structure and only modifies the code, the UI interface can be previewed in real-time without saving. Likewise, if you modify the properties in the properties box, the corresponding properties in the code will also be modified synchronously.

The code and interface can be modified in both directions, and developers can quickly adjust the interface style. Developers only need to click the icon on the previewer interface to use the two-way preview function.

One-time and Multi-Device Deployment:

Coming to one-time deployment, DevEco Studio 3.0 Beta1 is based on the UI adaptation capabilities of ArkUI 3.0, and provides developers with eTS language-based multi-device development project templates and card templates.

It means, while creating a project, developers only need to check the required devices to achieve one-time development and adaptation for a variety of equipment.

Simultaneously, DevEco Studio also provides a multi-device preview function and a custom profile, allowing developers to easily see the preview effects in multiple sizes, horizontal and vertical screens, bright and dark modes.

List of New Function of Huawei HarmonyOS DevEco Studio 3.0 Beta 1

New Features:

  • Added support for ArkUI 3.0 version of the Ark development framework and eTS (Extended TypeScript) extended syntax. eTS supports declarative UI grammar on the basis of TS, which is used to describe UI layout, style, event interaction, and page logic
  • Added project templates that support eTS, including multiple project templates such as Empty Ability, About Ability, and Category Ability
  • Added support for compiling with the Ark Compiler. This feature is an experimental feature and you need to manually turn on the Ark Compiler switch. The current JS/eTS atomization service, HarmonyOS application, and JS card support the use of the Ark compiler for the compilation
  • The new local evaluation tool Scoring Tool is used to test and evaluate the quality of HarmonyOS applications or atomic services. It is used by developers to self-test HarmonyOS applications or atomic services. It can quickly provide evaluation results and suggestions for improvement, helping developers quickly Improve product quality
  • When compiling and constructing the HAP package, new support for compiling a single Module is added. For scenarios where only one of the Modules needs to be compiled in a multi-module project, the compilation and construction speed can be improved; at the same time, support for the one-click reconstruction of the HAP package is added. Before compiling and building HAP, the Clean Project operation will be executed automatically

Enhanced Features:

The HarmonyOS SDK is upgraded to API 7 Beta version, the version number is, and the matching compile and build plug-in is The latest improvements of Huawei HarmonyOS DevEco 3.0 Beta 1 includes-

Remote simulator update

  1. Phone, Tablet, TV, Wearable emulators support API 6 Release
