React.js: Defining Custom Attributes

React has a few custom defined attributes. How can I define my own? Why? I have an Arc component, a few usage examples below: Copy

If you want to omit certain props, you can explicitly set them to null, e.g.

<pathstartAngle={null} />

but if the component you transfer the props to doesn't have such a prop anyway, it's not really necessary to do that.

See the documentation for more information.

Solution 2:

Starting React v0.12, transferPropsTo are replaced by JSX Spread Attributes:

return <path {...this.props}/>
