have you defined the props
variable anywhere, as this appears to be your issue? react prop types are available on react.proptypes
.
can you try this:
chatlist.proptypes = {
url: react.proptypes.string.isrequired
};
score:2
a few issues i noticed, which hopefully solves this issue.
since you are using es6 class to define react components,
getinitialstate
cannot be used like that. instead you should have:constructor(props) { super(props); this.state = { chat: [] }; }
you have
chatlist.proptypes = …
instead it should bechatlist.proptypes
(smallp
) andprops
is undefined, hence your error about 'cannot access property string of undefined'chatlist.proptypes = { url: react.proptypes.string.isrequired };
