According to the latest information, Huawei DevEco Studio (referred to as DevEco Studio) is a one-stop integrated development environment (IDE) for developing HarmonyOS applications and atomization services, providing developers with project template creation, Develop, compile, debug, release and other functions.
Now, Huawei DevEco Studio 3.0 Beta 3 has been released, the first version developed to support OpenHarmony applications and services.
Version Change Description
DevEco Studio 3.0 Beta3 is the first version to support OpenHarmony application and service development, with the following capabilities:
Support one-stop information acquisition platform
Based on the user journey that developers understand, learn, develop, and ask for help, we provide a one-stop information acquisition platform in DevEco Studio: OpenHarmony Information Center. This version is the first to go online and currently supports the following capabilities:
Provide OpenHarmony application development quick start, DevEco Studio release notes, content integration of FAQs, and experience immersive information reading experience.
Support online browsing and one-click creation of Sample
It supports the in-depth integration of document content and DevEco Studio functions. During the process of reading the document, you can pull up the corresponding functions of DevEco Studio and reach it with one click.
Support anonymous feedback from developers, your comments will be an important source of input for our DevEco Studio and documentation improvements.
Support the rapid acquisition of relevant resources during the development of OpenHarmony applications, and improve the efficiency of information acquisition.
Provide multi-device engineering templates
Project templates facilitate application development. Based on the declarative development paradigm and web-like development paradigm, DevEco Studio provides OpenHarmony developers with multi-device project templates and supports cross-device development. When developing an application/service, after the developer creates a project according to the wizard, DevEco Studio will automatically generate sample code and related resources. After the project is synchronized, it can be run directly. The developer does not need to type code from scratch, and can quickly get started.
Efficient code editing
In the stage of writing application or service code, using common code skills can improve coding efficiency. DevEco Studio provides various common skills such as code highlighting, code folding, and code formatting, and supports Lenovo completion, code jumping, code verification, etc., to achieve efficient code editing.
Support visual interface UI development
OpenHarmony low-code development provides an efficient visual design method, has rich UI interface editing functions, its interface and logic are separated, supports free drag & drop of various components, quick preview effects, what you see is what you get, and supports cards Zero-code development effectively improves the efficiency of building UI interfaces. Developers can choose to enable Super Visual when creating a project, enable the low-code development function, and open the “.visual” file in the project directory structure to design and develop the visual layout of the page.
Real-time preview: In the process of developing UI code, if you add or delete UI components, you just need to Ctrl+S to save, and the previewer will immediately refresh the preview results.
Dynamic preview: In the previewer interface, you can operate the interface interaction actions of the application/service in the previewer, such as click events, jumping, sliding, etc., which is consistent with the interface interaction experience of the application/service running on the real device.
Multi-device preview: Supports viewing the UI layout and interaction effects of applications/services on different devices, and supports up to 4 devices at the same time. Click the button in the upper right corner of the Previewer to turn on the Multi-profile preview switch in Profile Manager, and then you can view the running effect of applications/services on multiple devices at the same time.
Component preview: Support eTS component preview by adding the annotation @Preview in front of the component. In a single source file, you can use up to 10 @Preview to decorate custom components.
Brand new compilation tool Hvigor
For OpenHarmony-oriented JS/eTS development, based on the compiling, packaging and package management technologies in the JS field, DevEco Studio provides the automated build tool Hvigor to realize one-click automated construction of OpenHarmony applications/services.
Hvigor is a new front-end lightweight construction tool based on TS. Combined with the npm package management mechanism, it mainly provides key capabilities such as task management mechanism, task registration and scheduling, project model management, configuration management, and new command line entry, which is more in line with openHarmony Development habits of TS/JS developers.
