Taro UI 2.0 Release: New Components, Multi‑Mini‑Program Support, Custom Themes, Theme Generator, and Issue Helper

Six months after the initial release, Taro UI 2.0 adds eleven new components—including calendar, index selector, area selector, image selector, page prompts, separators, countdowns, curtains, step bars, global information components, and search bar—while also supporting additional mini‑program ecosystems such as Baidu.

The update brings a customizable theme feature that lets developers override SCSS variables in a dedicated custom-variables.scss file and import it at the project entry point, eliminating the need to duplicate default styles.

Two ready‑made themes (JD and 7Fresh) are provided, and a visual theme generator (available at https://nervjs.github.io/taro-ui-theme-preview/) enables developers to create and preview custom themes quickly.

An Issue Helper page and accompanying CLI tool (invoked with issue-helper build ) were created to guide contributors in filling issue templates correctly; the helper’s source code resides at https://github.com/jimczj/issue-helper.

Challenges encountered while adapting Taro UI to WeChat mini‑programs—such as Shadow DOM limitations, style scoping, native component layering, and lack of requestAnimationFrame—were resolved using Taro’s abstraction layer, and the team plans to add ByteDance mini‑program support and internationalization (i18n) in future releases.
