ReactJS writing stateless function comments

You can specify props object before property name:

/**
 * Form for user login
 * @param {object} props Component props
 * @param {bool} props.submitting Shows if form submitting is in progress
 * @param {function} props.handleSubmit Form submit callback function
 */
export const LoginForm = ({ submitting, handleSubmit }) => (
  <form onSubmit={handleSubmit(submit)}> ...(code)... </form>
));

For more info see @param wiki page in Parameters With Properties section.


I know I am almost 3 years late to this party. Just adding for reference. One could do this:

/**
 * @typedef {Object<string, any>} Props
 * @property {boolean} submitting Shows if form submitting is in progress
 * @property {function} handleSubmit Form submit callback function
 */

/** 
 * Form for user login
 *
 * @type {import('react').FunctionComponentElement<Props>}
 */
export const LoginForm = ({ submitting, handleSubmit }) => (
    <form onSubmit={handleSubmit(submit)}> ...(code)... </form>
);

For brevity, one could also do:

/**
 * Form for user login
 *
 * @type {import('react').FunctionComponentElement<{
       submitting: boolean,
       handleSubmit: function
    }>}
 */
export const LoginForm = ({ submitting, handleSubmit }) => (
    <form onSubmit={handleSubmit(submit)}> ...(code)... </form>
);

If Typescript is enabled in your IDE, you could avoid declaring prop-types altogether with this setup.
