5 best practices for building a modern API with Express

• cors

  10 5,966 0.0 JavaScript

  Node.js CORS middleware

  

You can add the cors middleware package to your application to help you send the correct CORS response headers from your API endpoints. By default, the headers it sends will allow any web page to make requests to your API, so make sure you check out the configuration options, and at the very least set the origin option so that you are restricting which web pages are able to call your API (unless you’re running an API for public use, in which case this won’t be an issue).

• express-json-validator-middleware

  1 158 3.5 JavaScript

  Express middleware for validating requests against JSON schema

The express-json-validator-middleware package brings support for JSON Schema into your application and enables you to validate requests to your API against any schemas that you define and configure it to use. The ‘Example Express app‘ in the package documentation gives a really good example of how you can use it for your API.
