At the 2021 Huawei Developer Conference (HDC2021), Huawei released a new generation of declarative UI framework – Ark Development Framework (ArkUI). The ArkUI framework introduces a declarative development paradigm based on TS extensions. Since then, more and more developers have joined the JS / eTS development team, and Huawei has also received many developers’ demands for JS / eTS components, such as:
With the joint efforts of the majority of component contributors, Huawei has ushered in a new batch of open source components, including many JS/eTS components.
Overview of new open source components:
- A total of 94 open source components have been added. Components involve tools, networking, UI, graphics, audio and video and other functions.
- Most of the new components are in JS / TS / eTS language, which greatly helps JS / eTS developers in their development journey.
- Four typical components are – zxing, VCard, CommonsCompressEts and httpclient.
- Huawei has only open sourced the Java version of the zxing library (Zxing-Embedded) before. The new TS version of the zxing library will allow eTS developers to use the zxing library for QR code-related application development.
- This time the new VCard component of the eTS version supports VCard standard 2.0 and 3.0. The interfaces provided are: nickname, name, phone, email, address, social tools, website address, organization, photo address, notes, group, events and relationships.
- CommonsCompressEts is an API library developed based on the eTS language, providing compression and decompression functions for more than ten file formats. File formats include: zip, gzip, xz, z, zstd, ar, brotli, bzip2, lz4, lzma (seven7), tar, snappy, dump, deflate, cpio.
- httpclient (ie HTTP client), based on the well-known okhttp, integrates the functional characteristics of android-async-http, AutobahnAndroid, OkGo and other libraries, and is committed to creating an efficient, easy-to-use and comprehensive network request library. With this httpcilent, your content loads faster and saves bandwidth.
3. How to obtain open source components?
Developers can directly download the source code through the OpenHarmony three-party component library (OpenHarmony-TPC) or obtain related components from the HarmonyOS Developer Resource Center (DevEco Marketplace).
