Chinese Web IG's idea

Timeline of MiniApps Activities

The Chinese Web IG started the work in 2019, publishing the White Paper on MiniApp Standardization, written by Alibaba, Xiaomi, Baidu, Intel, Huawei, and China Mobile. Months later they formed the MiniApps CG, with participation also from Google, Microsoft, Bytedance, 360 and other W3C Members.

(2021) Standardization begins

Timeline of MiniApps Activities

In 2021, the MiniApps WG was launched. Xu Fuqiao as Team Contact, and Co-Chairs from Alibaba, Baidu, and Huawei. During that period, the first WDs were published.

Timeline of MiniApps Activities

In 2024, we had discussions at TPAC about the specs. Internationalization, Accessibility and Privacy was fine, but some challenges in terms of security (MiniApps model is different than the Web security model).
