noUndeclaredDependencies (since v1.6.0)

Diagnostic Category: lint/nursery/noUndeclaredDependencies

Disallow the use of dependencies that aren’t specified in the package.json.

Indirect dependencies will trigger the rule because they aren’t declared in the package.json. This means that if package @org/foo has a dependency on lodash, and then you use import "lodash" somewhere in your project, the rule will trigger a diagnostic for this import.

The rule ignores imports using a protocol such as node:, bun:, jsr:, https:.

import "vite";
import { A } from "./local.js";
import assert from "node:assert";
