DejaOS modules are the cornerstone of our entire ecosystem. To unify interface specifications, improve code quality, and enhance ease of use, we have recently launched a long-term module iteration plan to comprehensively review and optimize all existing official modules.

Brand-New Modules for a Smooth Transition​

Some modules have undergone significant refactoring, with rewrites from the underlying C/C++ implementation to the high-level JavaScript APIs. To ensure a smooth transition, we have introduced more powerful new modules with unified interfaces to replace the old ones. The old modules will be marked as "deprecated" but will remain available for a long time to ensure backward compatibility.

The main module replacements are as follows:

  • dxHttpClient → dxHttp
  • dxHttpServer → dxWebserver
  • dxMqttClient → dxMqtt
  • dxNetwork → dxNet
  • dxBarcode → dxCode
  • dxConfiguration → dxConfig
  • dxAudio → dxAlsa, dxAlsaplay
  • dxOs, dxCommonUtils → dxCommon

Seamless Upgrades with Backward Compatibility​

For the remaining modules that were not replaced, we have implemented functional upgrades and optimizations. The core usage of these modules remains largely unchanged, with only minor adjustments to a few functions. When such changes occur, we will provide clear deprecation notices in the logs and guide you to use the new alternative functions.

Documentation Has Been Updated​

All updated modules are now accompanied by brand-new documentation. You can find detailed API references and usage examples in the Official DejaOS Modules Documentation.

We believe this comprehensive module upgrade will bring you a more stable, efficient, and enjoyable development experience.
