require-returns-description

Requires that the @returns tag has a description value. The error will not be reported if the return value is void or undefined or if it is Promise<void> or Promise<undefined>.

Options

A single options object has the following properties.

contexts

Set this to an array of strings representing the AST context (or an object with optional context and comment properties) where you wish the rule to be applied.

context defaults to any and comment defaults to no specific comment context.

Overrides the default contexts (ArrowFunctionExpression, FunctionDeclaration, FunctionExpression). Set to "any" if you want the rule to apply to any JSDoc block throughout your files (as is necessary for finding function blocks not attached to a function declaration or expression, i.e., @callback or @function (or its aliases @func or @method) (including those associated with an @interface).

See the "AST and Selectors" section of our Advanced docs for more on the expected format.

Failing examples

The following patterns are considered problems:

/**
 * @returns
 */
function quux (foo) {

}
// Message: Missing JSDoc @returns description.

/**
 * @returns {string}
 */
function quux (foo) {

}
// Message: Missing JSDoc @returns description.

/**
 * @returns {string}
 */
function quux (foo) {

}
// "jsdoc/require-returns-description": ["error"|"warn", {"contexts":["any"]}]
// Message: Missing JSDoc @returns description.

/**
 * @function
 * @returns {string}
 */
// "jsdoc/require-returns-description": ["error"|"warn", {"contexts":["any"]}]
// Message: Missing JSDoc @returns description.

/**
 * @callback
 * @returns {string}
 */
// "jsdoc/require-returns-description": ["error"|"warn", {"contexts":["any"]}]
// Message: Missing JSDoc @returns description.

/**
 * @return
 */
function quux (foo) {

}
// Settings: {"jsdoc":{"tagNamePreference":{"returns":"return"}}}
// Message: Missing JSDoc @return description.

/**
 * @returns
 */
function quux () {

}
// Settings: {"jsdoc":{"tagNamePreference":{"returns":false}}}
// Message: Unexpected tag `@returns`

Passing examples

The following patterns are not considered problems:

/**
 *
 */
function quux () {

}

/**
 * @returns Foo.
 */
function quux () {

}

/**
 * @returns Foo.
 */
function quux () {

}
// "jsdoc/require-returns-description": ["error"|"warn", {"contexts":["any"]}]

/**
 * @returns {undefined}
 */
function quux () {

}

/**
 * @returns {void}
 */
function quux () {

}

/**
 * @returns {Promise<void>}
 */
function quux () {

}

/**
 * @returns {Promise<undefined>}
 */
function quux () {

}

/**
 * @function
 * @returns
 */

/**
 * @callback
 * @returns
 */
