React v16.13.0

By reactjs.org
Published On :: Wed, 26 Feb 2020 00:00:00 GMT

Today we are releasing React 16.13.0. It contains bugfixes and new deprecation warnings to help prepare for a future major release.

New Warnings

Warnings for some updates during render

A React component should not cause side effects in other components during rendering.

It is supported to call setState during render, but only for the same component. If you call setState during a render on a different component, you will now see a warning:

Warning: Cannot update a component from inside the function body of a different component.

This warning will help you find application bugs caused by unintentional state changes. In the rare case that you intentionally want to change the state of another component as a result of rendering, you can wrap the setState call into useEffect.

Warnings for conflicting style rules

When dynamically applying a style that contains longhand and shorthand versions of CSS properties, particular combinations of updates can cause inconsistent styling. For example: 

<div style={toggle ? 
  { background: 'blue', backgroundColor: 'red' } : 
  { backgroundColor: 'red' }
}>
  ...
</div>

You might expect this <div> to always have a red background, no matter the value of toggle. However, on alternating the value of toggle between true and false, the background color start as red, then alternates between transparent and blue, as you can see in this demo.

React now detects conflicting style rules and logs a warning. To fix the issue, don’t mix shorthand and longhand versions of the same CSS property in the style prop.

Warnings for some deprecated string refs

String Refs is an old legacy API which is discouraged and is going to be deprecated in the future:

<Button ref="myRef" />

(Don’t confuse String Refs with refs in general, which remain fully supported.)

In the future, we will provide an automated script (a “codemod”) to migrate away from String Refs. However, some rare cases can’t be migrated automatically. This release adds a new warning only for those cases in advance of the deprecation.

For example, it will fire if you use String Refs together with the Render Prop pattern:

class ClassWithRenderProp extends React.Component {
  componentDidMount() {
    doSomething(this.refs.myRef);
  }
  render() {
    return this.props.children();
  }
}

class ClassParent extends React.Component {
  render() {
    return (
      <ClassWithRenderProp>
        {() => <Button ref="myRef" />}
      </ClassWithRenderProp>
    );
  }
}

Code like this often indicates bugs. (You might expect the ref to be available on ClassParent, but instead it gets placed on ClassWithRenderProp).

You most likely don’t have code like this. If you do and it is intentional, convert it to React.createRef() instead:

class ClassWithRenderProp extends React.Component {
  myRef = React.createRef();
  componentDidMount() {
    doSomething(this.myRef.current);
  }
  render() {
    return this.props.children(this.myRef);
  }
}

class ClassParent extends React.Component {
  render() {
    return (
      <ClassWithRenderProp>
        {myRef => <Button ref={myRef} />}
      </ClassWithRenderProp>
    );
  }
}

Note

To see this warning, you need to have the babel-plugin-transform-react-jsx-self installed in your Babel plugins. It must only be enabled in development mode.

If you use Create React App or have the “react” preset with Babel 7+, you already have this plugin installed by default.

Deprecating React.createFactory

React.createFactory is a legacy helper for creating React elements. This release adds a deprecation warning to the method. It will be removed in a future major version.

Replace usages of React.createFactory with regular JSX. Alternately, you can copy and paste this one-line helper or publish it as a library:

let createFactory = type => React.createElement.bind(null, type);

It does exactly the same thing.

Deprecating ReactDOM.unstable_createPortal in favor of ReactDOM.createPortal

When React 16 was released, createPortal became an officially supported API.

However, we kept unstable_createPortal as a supported alias to keep the few libraries that adopted it working. We are now deprecating the unstable alias. Use createPortal directly instead of unstable_createPortal. It has exactly the same signature.

Other Improvements

Component stacks in hydration warnings

React adds component stacks to its development warnings, enabling developers to isolate bugs and debug their programs. This release adds component stacks to a number of development warnings that didn’t previously have them. As an example, consider this hydration warning from the previous versions:

While it’s pointing out an error with the code, it’s not clear where the error exists, and what to do next. This release adds a component stack to this warning, which makes it look like this:

This makes it clear where the problem is, and lets you locate and fix the bug faster.

Notable bugfixes

This release contains a few other notable improvements:

  • In Strict Development Mode, React calls lifecycle methods twice to flush out any possible unwanted side effects. This release adds that behaviour to shouldComponentUpdate. This shouldn’t affect most code, unless you have side effects in shouldComponentUpdate. To fix this, move the code with side effects into componentDidUpdate.
  • In Strict Development Mode, the warnings for usage of the legacy context API didn’t include the stack for the component that triggered the warning. This release adds the missing stack to the warning.
  • onMouseEnter now doesn’t trigger on disabled <button> elements.
  • ReactDOM was missing a version export since we published v16. This release adds it back. We don’t recommend using it in your application logic, but it’s useful when debugging issues with mismatching / multiple versions of ReactDOM on the same page.

We’re thankful to all the contributors who helped surface and fix these and other issues. You can find the full changelog below.

???? A Q&A with…
Thibaut Barrère
Creator of Kiba ETL

Thibaut Barrère is a long-time Rubyist and data engineer who built and maintains the popular Extract, Transform, and Load (ETL) framework Kiba. We asked him some questions about his work:

What inspired you to create Kiba?

A lot of my work since ~2005 has been focused on data integration (making systems speak together), data aggregation etc. I sometimes used GUI-based tools like Microsoft SSIS which, while powerful, are quite far from the coding experience.

I was already using Ruby at that time, and was happy to discover activewarehouse-etl (maintained by Anthony Eden, who runs DNSimple now) providing a Ruby DSL to declare data pipelines. I used it for a while with very good success to implement data extractions and business intelligence ETL, and ultimately took over the maintenance.

In the long run, though (as I explained in a recent Paris.rb talk), the balance between the the cost of OSS maintenance and the usability for my billable and non-billable use-cases proved to be not good enough, which made me decide to stop the maintenance, sadly.

I still wanted to use Ruby to write data pipelines, but I needed to cover more use-cases and reduce the OSS maintenance burden at the same time. This ultimately led me to write and share (in 2015) Kiba ETL, a focused DSL for declarative processing, matching those criterias.

Do you find yourself adding more features while in quarantine?

Before the quarantine, I directed my Kiba bandwith and focus on finalizing Kiba v3 and rewriting the documentation from scratch, to properly encourage best practices I’ve been discovering. I also created experimental branches for Ruby 2.7/2.8 keywords.

During the quarantine, I've reduced client work and OSS work too, to focus on shipping Kiba Pro v2 (which I’ll announce shortly officially). I’ve extracted and generalized (from real-life projects) very useful components, such as a “batch SQL lookup” (useful when replacing relationships keys during data migrations and datawarehouses sync code, in batch rather than row by row), a “file lock” to ensure a single job runs at once, and a “parallel transform” to achieve easy concurrency for things like HTTP queries.

What's the wildest ETL that you've encountered?

Getting the data out of a system which is actively not acting in that direction is always a bit wild.. One can see all types of fancy stuff on the field. For instance, it is not uncommon to have an ETL process start a headless browser, jump through pages, just to get to the CSV/PDF/Excel file that you will then use as your data source!

You can also end up having to figure out ways to read or write very old file formats at times. Recently I wrote a Kiba component to generate a COBOL delimited file, for instance. In large companies, a very widely used I/O is good old SFTP, far away from modern APIs and formats.

Can you tell us how to say your last name? ????

I had to deploy a page to my blog to answer that question properly ????. You’ll find out how to say my name here.

Merci Thibaut!
