🦋 express-openapi-validator

An OpenApi validator for ExpressJS that automatically validates API requests and responses using an OpenAPI 3 specification.

🦋express-openapi-validator is an unopinionated library that integrates with new and existing API applications. express-openapi-validator lets you write code the way you want; it does not impose any coding convention or project layout. Simply, install the validator onto your express app, point it to your OpenAPI 3 specification, then define and implement routes the way you prefer. See an example.

Features:

✔️ request validation
✔️ response validation (json only)
👮 security validation / custom security functions
👽 3rd party / custom formats / custom data serialization-deserialization
🧵 optionally auto-map OpenAPI endpoints to Express handler functions
✂️ $ref support; split specs over multiple files
🎈 file upload

3## latest beta
4npm install express-openapi-validator@4.14.0-beta.1

Usage

Require/import the openapi validator

1const OpenApiValidator = require('express-openapi-validator');

1import * as OpenApiValidator from 'express-openapi-validator';

Install the middleware

1app.use(
2  OpenApiValidator.middleware({
3    apiSpec: './openapi.yaml',
4    validateRequests: true, // (default)
5    validateResponses: true, // false by default
6  }),
7);

1app.use((err, req, res, next) => {
2  // format error
3  res.status(err.status || 500).json({
4    message: err.message,
5    errors: err.errors,
6  });
7});

Important: Ensure express is configured with all relevant body parsers. Body parser middleware functions must be specified prior to any validated routes. See an example.
