eslint-nestjs-apiresponse
A simple ESLint plugin that enforces the use of HttpStatus enum from @nestjs/common in NestJS applications.
Features
- Enforces the use of
HttpStatus
enum instead of numeric literals - Works with both
@ApiResponse
decorators and returned response objects - Automatically adds
HttpStatus
import when missing - Includes autofix functionality
- Full TypeScript support out of the box
Installation
npm install eslint-nestjs-apiresponse --save-dev
Usage
For ESLint 9+ (flat config), add to your eslint.config.js
or eslint.config.mjs
:
import nestjsApiResponse from "eslint-nestjs-apiresponse";
export default [
{
plugins: {
"eslint-nestjs-apiresponse": nestjsApiResponse
},
rules: {
"eslint-nestjs-apiresponse/require-http-status": "error"
}
}
];
For ESLint 8 and below (.eslintrc
):
{
"plugins": ["eslint-nestjs-apiresponse"],
"rules": {
"eslint-nestjs-apiresponse/require-http-status": "error"
}
}
Or use the recommended configuration:
{
"extends": ["plugin:eslint-nestjs-apiresponse/recommended"]
}
Running from CLI
To run the plugin directly from command line:
# Check files
npx eslint --rule 'eslint-nestjs-apiresponse/require-http-status: error' src/
# With auto-fix
npx eslint --rule 'eslint-nestjs-apiresponse/require-http-status: error' --fix src/
Examples
❌ Incorrect:
// In decorators
@ApiResponse({ status: 200, description: 'Success' })
// In response objects
return { status: 200, data: result };
✅ Correct:
import { HttpStatus } from '@nestjs/common';
// In decorators
@ApiResponse({ status: HttpStatus.OK, description: 'Success' })
// In response objects
return { status: HttpStatus.OK, data: result };
TypeScript Support
The plugin includes TypeScript type definitions out of the box. No additional @types
packages are required. Just install and use - TypeScript will automatically pick up the type definitions.
