I am using ReactJS do develop a simple chat application. Could someone help me to sanitize the input . There is only one input text box to send chat messages. How to sanitize it?.
<input type="text" className="chat" value={this.state.name} /> Based on the documentations HTML escapes html by default. Is it enough?. Do I need to add any other sanitization methods. If yes, please let me know how to do that?.

It's sanitized by default, you don't need a sanitization method unless you are using dangerouslySetInnerHTML which is not the case. Are there any documentation on this?. facebook.github.io/react/docs/… "By default, React DOM escapes any values embedded in JSX before rendering them.
sanitize-html provides a simple HTML sanitizer with a clear API. sanitize-html is tolerant. It is well suited for cleaning up HTML fragments such as those created by ckeditor and other rich text editors.
XSS attacks can inject malicious code into your application, which can be used to steal users' data or damage your application. Needless to say, cross-site scripting (XSS) is a big security risk. If you want to develop React application that is secure.
Would the ReactJS automatically do that for us. It's sanitized by default, you don't need a sanitization method unless you are using dangerouslySetInnerHTML which is not the case.

It cleanses the original data to prevent it from exploiting any security holes in your application. I don’t recommend doing input sanitizing because you may risk altering the data in ways that make it unusable.
Again, sanitizing really depends on the context of the data. There are cases where sanitizing input is a must. To sanitize the users input data you can still use validator.js as I demonstrated above. Validator.js is supported with both client-side and back-end code.
So validate in the back-end code as well. Sanitizing data is best done before displaying the data to the user screen.
