Readme
A ReactJS Mixin to ensure that components explicitly define the properties they
allow in their propTypes
. If a property passed in to the React component is
not found in propTypes
then an error will be thrown.
This is useful for ensuring that all component property interfaces be explicitly defined, which helps when reasoning about what properties a component will accept.
Let's keep our interfaces clean and well documented!
Let's define a very basic React component.
var ExplicitPropDeclarationMixin = require('react_explicit_prop_declaration');
var MyComponent = React.createClass({
mixins: [ExplicitPropDeclarationMixin],
propTypes: {
defined: React.PropTypes.bool
},
render: function () {
// ...
}
});
And now let's render that component with the property we defined in propTypes
:
React.render(<MyComponent defined={true}} />
Cool, so let's do the same, but this time, with a property we did not define in
propTypes
.
React.render(<MyComponent notDefined={false} defined={true}} />
Eeek! An error was thrown telling us what went wrong!
ExplicitPropDeclarationError: The properties "notDefined" were set on the MyComponent, which were not declared in MyComponent.propTypes. Only properties defined in MyComponent.propTypes are allowed to be set on MyComponent.
Looks like, we, as developers need to decide to explicitly define another
propType
we allow on this component, or fix our render
call to not pass in
unexpected properties.

Please do not iterate the package.json version number – I will do that myself when I publish it to NPM.
