import/no-deprecated

Reports use of a deprecated name, as indicated by a JSDoc block with a @deprecated tag or TomDoc Deprecated: comment.

using a JSDoc @deprecated tag:

// @file: ./answer.js

/**
 * this is what you get when you trust a mouse talk show
 * @deprecated need to restart the experiment
 * @returns {Number} nonsense
 */
export function multiply(six, nine) {
  return 42
}

will report as such:

import { multiply } from './answer' // Deprecated: need to restart the experiment

function whatever(y, z) {
  return multiply(y, z) // Deprecated: need to restart the experiment
}

or using the TomDoc equivalent:

// Deprecated: This is what you get when you trust a mouse talk show, need to
// restart the experiment.
//
// Returns a Number nonsense
export function multiply(six, nine) {
  return 42
}

Only JSDoc is enabled by default. Other documentation styles can be enabled with the import/docstyle setting.

Worklist

• report explicit imports on the import node
• support namespaces
  • should bubble up through deep namespaces (#157)
• report explicit imports at reference time (at the identifier) similar to namespace
• mark module deprecated if file JSDoc has a @deprecated tag?
• don't flag redeclaration of imported, deprecated names
• flag destructuring
