Use AI for Precision Notes
1- I like to explain my logic and any edge cases as I reason them out, things I've thought of when processing certain data, and how critical it may be. Things that might fail at some point. Examples of why and how they might fail. Even if simple a quick / dirty notes. Then I do a second pass using AI on each function. I ask it to redact the notes, add precision notes when necessary, and reformulate what I've already written to be more presentable. This has helped me a lot, as I used to do this all manually before AI. I think it saves me about 20-30 minutes a day, depending on how much I've written.
Generate Beautiful API Documentation
The best way to document an API is by using the OpenAPI specification - specifically version 3. With an OpenAPI document, you can use tools like Zudoku (https://zudoku.dev/) to generate beautiful API documentation for your API that includes UX features that are hard to build. This includes an API playground, built-in auth management, schema example generation, etc. I would recommend choosing a free and open source tool that you can easily customize - but beware of open source tools that gatekeep features behind a managed service.
Define and Document APIs with Swagger
My preferred method for documenting backend code and APIs is to use Swagger (OpenAPI). It's an industry-standard tool that allows you to define and document APIs in a structured way. With Swagger, you can generate interactive API documentation that not only describes the endpoints, request parameters, and responses but also allows developers to test the APIs directly from the documentation interface. This makes it super easy for both developers and other stakeholders to understand how the API works and integrate it into their applications.
The big advantage of using Swagger is its automated generation of documentation from your API code, ensuring that your docs stay up-to-date as your API evolves. This reduces the chances of outdated or inconsistent documentation. Plus, it supports both RESTful and GraphQL APIs, making it a versatile choice for modern backend architectures. For teams working collaboratively, it's a great tool to make sure everyone is on the same page when it comes to API usage and updates.
Integrate Springfox for Real-Time Documentation
As a Java/Spring Boot developer, I find Springfox's SwaggerUI to be the best tool for documenting backend code and APIs. It integrates seamlessly with Spring Boot, automatically generating interactive API documentation from your controller annotations like @ApiOperation and @ApiParam. This eliminates the need for manual documentation, keeping the docs consistent with the code.
In one project, we had a complex microservice architecture where clear API documentation was critical for collaboration. By integrating Springfox, we provided real-time, user-friendly docs directly from our endpoints. This not only sped up development for frontend teams but also reduced miscommunication around API contracts. Its interactive UI allowed developers to test endpoints directly, which streamlined debugging and ensured better alignment across teams.
