This is a good first PR!

We should add some tests to cover #7036. They should cover both JavaScript and TypeScript support.

They can probably be added to test/fixtures.

Bug report

Describe the bug

when modifying the mobx state data, the latest data is not rendered

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. git clone https://github.com/Fullsize/next.js
2. yarn install
3. yarn dev
4. open the browser and enter localhost:3000
5. open user.store.ts to modify userName and view

Summary

Where: https://www.gatsbyjs.org/docs/ssr-apis/#onRenderBody

What: Improve the example for onRenderBody or add another example, simple, that is not tied to a plugin.

Suggestion

// Object of props
const HtmlAttributes = {
  "data-whatever": "content"
}

// Magic
exports.onRenderBody = (
  { setHtmlAttributes }
) => {
   setHtmlAttributes(HtmlAttributes)
}

any plans for a Linux ARM build? if nobody else is on it or has attempted it, i can give it a try.

At some point we moved from using mocha as a test runner to using jest, and jest out of the box started reporting much more warnings than mocha did.

No one went to clean up this output. In many cases it may just be about passing an extra prop in a component or setting a proper default value for a component's prop, or adding up to an existing fixture.

问题描述
最近使用movable-view做了一个拖拽排序的功能，但是由于需要touchmove事件频繁setState来更新movable-view的坐标，导致Android的上的性能体验很差，IOS不会。

看了微信的文档，这种情况可以使用WXS来解决，请问Taro中能否使用WXS？如何使用呢？

Current Behavior

The type ErrorMessage doesn't have an id property.

Desired Behavior

It'd be nice id?: string would be added to the type ErrorMessage and set on the outermost component that serves as error message.

Suggested Solution

Add id={this.props.id} to the outer component in ErrorMessage.

Who does this impact? Who is this

Since version 0.16.5, th following code returns a null worksheet:
XLSX.utils.json_to_sheet([], {header: columns})

Is it now working as it is wanted? If so, how could we create an empty worksheet? In my case it is expected that sometimes the data is an empty array. And an empty worksheet only with headers is expected.
