JSDoc: Return object structure

Question

How can I tell JSDoc about the structure of an object that is returned. I have found the @return {{field1: type, field2: type, ...}} description syntax and trie

Answer 1

An alternative to the suggestions already posted, you can use this format:

/**
 * Get the connection state.
 *
 * @returns {Object} connection The connection state.
 * @returns {boolean} connection.isConnected Whether the authenticated user is currently connected.
 * @returns {boolean} connection.isPending Whether the authenticated user's connection is currently pending.
 * @returns {Object} connection.error The error object if an error occurred.
 * @returns {string} connection.error.message The error message.
 * @returns {string} connection.error.stack The stack trace of the error.
 */
getConnection () {
  return {
    isConnected: true,
    isPending: false,
    error
  }
}

which will give the following documentation output:

    Get the connection state.

    getConnection(): Object

    Returns
    Object: connection The connection state.
    boolean: connection.isConnected Whether the authenticated user is currently connected.
    boolean: connection.isPending Whether the authenticated users connection is currently pending.
    Object: connection.error The error object if an error occurred.
    string: connection.error.message The error message.
    string: connection.error.stack The stack trace of the error.
