babel-plugin-transform-react-handled-props
Generates handledProps from defaultProps and propTypes during the build ✨
Installation
$ yarn add --dev babel-plugin-transform-react-handled-props
This plugin is for Babel 7. If you need to support Babel 6 use the babel6 branch.
Story
This plugin was originally created for Semantic UI React package. It implements useful pattern with handled props by component, using it you can let down unhandled props to child component.
Motivation
Let's take an example from real life. There are cases when you need to pass some of the props to the child component. The simplest way is to use the destruction of the object.
const Foo = props const className ...rest = props const classes = return <div = />
The solution is simple and straightforward, but what if the props that will need to be handled is not used in the method? We still need to specify it explicitly.
Component thisprops { const className onClick ...rest = thisprops const classes = return <div = = /> }
And what if there are a lot of components? Yes, we will come to another solution, it's to rely on the React's propTypes
.
It's a good and logical solution.
Component static propTypes = className: PropTypesstring onClick: PropTypesfunc thisprops { const className = thisprops const classes = const rest = _ return <div = = /> }
Looks pretty good? But, there is only one problem, we don't need propTypes
in the production build.
We can take the plugin to remove them, but then our solution will be broken?
It's possible that you already use this approach, but you can't get rid of propTypes
in the your bundle.
This plugin solves the described problem, so you can rely on propTypes
and at the same time remove them from the production build.
Component static propTypes = className: PropTypesstring onClick: PropTypesfunc thisprops { const className = thisprops const classes = const rest = _ return <div = = /> }
Example transform
In
const Baz = <div ...props /> BazpropTypes = children: PropTypesnode className: PropTypesstring
Out
const Baz = <div ...props /> BazhandledProps = 'className' 'children'; BazpropTypes = children: PropTypesnode className: PropTypesstring
Usage
.babelrc
(Recommended)
Via .babelrc
Via CLI
$ babel --plugins transform-react-handled-props script.js
Via Node API
;
Options
ignoredProps
This options allows to ignore some props, this will allow to not add them to handledProps
.
In
const Baz = <div ...props /> BazpropTypes = children: PropTypesnode className: PropTypesstring
Out
const Baz = <div ...props /> BazhandledProps = 'className'; BazpropTypes = children: PropTypesnode className: PropTypesstring
Is it safe?
Absolutely 😎 You can also use in production with babel-plugin-transform-react-remove-prop-types and it will work perfectly.
const Baz = { const rest = _ return <div ...props> <Foo ...rest /> </div> }
