eslint-plugin-implicit-dependencies

1.1.1 verified Sat Apr 25 auth: no javascript

ESLint plugin (v1.1.1) that flags imports or require() calls to modules not listed in the project's package.json dependencies. Uses the 'no-implicit' rule to prevent accidental reliance on transitive dependencies. Lightweight, no runtime dependencies, works with both CJS require and ES import syntax. Differentiates from similar plugins by focusing solely on implicit dependency detection with minimal configuration.

Common errors

error Error: Failed to load plugin 'implicit-dependencies': Cannot find module 'eslint-plugin-implicit-dependencies' ↓

cause Plugin not installed locally.

fix

npm install eslint-plugin-implicit-dependencies --save-dev

error Definition for rule 'implicit-dependencies/no-implicit' was not found ↓

cause Plugin not listed in 'plugins' section of ESLint config.

fix

Add 'implicit-dependencies' to the plugins array.

Warnings

gotcha By default, only 'dependencies' are checked. Transient dependencies in devDependencies or peerDependencies are ignored unless explicitly configured. ↓

fix Add options: { dev: true, peer: true, optional: true } to the rule.

gotcha The plugin does not handle dynamic require() or import() expressions; only static imports and requires are detected. ↓

fix Use static import statements or add the dynamic module to package.json explicitly.

gotcha Monorepo setups: Only the root package.json is read; subpackage dependencies may be incorrectly flagged. ↓

fix Run ESLint separately per package, or use a monorepo-aware alternative.

Install

npm install eslint-plugin-implicit-dependencies

yarn add eslint-plugin-implicit-dependencies

pnpm add eslint-plugin-implicit-dependencies

Imports

default
wrong
```
plugins: ['eslint-plugin-implicit-dependencies']
```
correct
```
plugins: ['implicit-dependencies']
```
ESLint plugin naming convention allows omitting the eslint-plugin- prefix.
no-implicit rule
wrong
```
rules: { 'no-implicit': 'error' }
```
correct
```
rules: { 'implicit-dependencies/no-implicit': 'error' }
```
Rule is namespaced under the plugin. Always use the full 'implicit-dependencies/no-implicit' key.
CommonJS require
```
require('eslint-plugin-implicit-dependencies')
```
For programmatic use in .eslintrc.js or config file. Not recommended; prefer string plugin names.

Quickstart

Configure ESLint to error on any import not listed in package.json dependencies or devDependencies.

// .eslintrc.json
{
  "plugins": ["implicit-dependencies"],
  "rules": {
    "implicit-dependencies/no-implicit": ["error", { "dev": true }]
  }
}
