Supercharge Your API Documentation with ChatGPT and Express!

Posted: 4/7/2024

Hey there! Ever felt overwhelmed by the daunting task of creating API documentation? Well, worry not, because today I'm going to show you how combining ChatGPT and Express can turn this chore into a breeze.

Imagine you have Express, the backbone of your application, handling all your routing needs. Defining endpoints becomes as simple as snapping your fingers.

Now, let's introduce ChatGPT into the mix. Think of it as your trusty sidekick, ready to assist at a moment's notice. Just feed it your Express router, and watch as it effortlessly churns out a complete OpenAPI collection.

But why bother with this combo? Well, let me ask you a question:

Ever spent hours crafting API docs from scratch? With ChatGPT, that's a thing of the past.

Confused about how to structure your endpoints effectively? Express lays it all out for you like a pro.

Struggling to keep your docs up-to-date as your project evolves? ChatGPT swoops in to save the day.

Here’s the scoop

You toss your Express router to ChatGPT, and voila! You receive a shiny, organized OpenAPI spec ready for action.

Prompt it right

given the following express endpoint definition, create a insomnia compatible collection with a request for every known endpoint: 

const routes = Router();
routes.get("/auth/install", AuthenticationController.install);
routes.post("/auth/login", AuthenticationController.login);
routes.param("user_id", checkUserCredentialsMiddleware);
routes.post("/:user_id/products", ProductController.create);
routes.get("/:user_id/products/total", ProductController.getTotal);
routes.get("/:user_id/products", ProductController.getAll);

routes.delete("/:user_id/products/:id", ProductController.delete);

Let's put it into perspective with an analogy. Imagine baking a cake without a recipe—it's chaos! But with ChatGPT and Express, it's like having a master chef guide you every step of the way.

Now, I recently asked ChatGPT to generate OpenAPI specs for my project, and let me tell you, the results were astounding. No more manual documentation headaches—just efficient, automated magic.

So, next time you're drowning in API docs, remember this powerful duo. With ChatGPT and Express, you'll have those docs whipped up in no time. Give it a try and watch your productivity soar!
