description
Disallow certain triple slash directives in favor of ES6-style import declarations.

🛑 This file is source code, not the primary documentation location! 🛑

See https://typescript-eslint.io/rules/triple-slash-reference for documentation.

TypeScript's /// triple-slash references are a way to indicate that types from another module are available in a file. Use of triple-slash reference type directives is generally discouraged in favor of ECMAScript Module imports. This rule reports on the use of /// <reference path="..." />, /// <reference types="..." />, or /// <reference lib="..." /> directives.

Examples

Options

With { "path": "never", "types": "never", "lib": "never" } options set, the following will all be incorrect usage:

/// <reference path="foo" />
/// <reference types="bar" />
/// <reference lib="baz" />

Examples of incorrect code for the { "types": "prefer-import" } option. Note that these are only errors when both styles are used for the same module:

/// <reference types="foo" />
import * as foo from 'foo';

/// <reference types="foo" />
import foo = require('foo');

With { "path": "always", "types": "always", "lib": "always" } options set, the following will all be correct usage:

/// <reference path="foo" />
/// <reference types="bar" />
/// <reference lib="baz" />

Examples of correct code for the { "types": "prefer-import" } option:

import * as foo from 'foo';

import foo = require('foo');

When To Use It

If you want to ban use of one or all of the triple slash reference directives, or any time you might use triple-slash type reference directives and ES6 import declarations in the same file.

When Not To Use It

If you want to use all flavors of triple slash reference directives.
