Application Programming Interface (API) is a set of subroutine definitions, protocols, and tools for building application software. In general terms, it is a set of clearly defined methods of communication between various software components.
We didn't start with a big AI strategy.
We had a legacy InterSystems Caché 2018 application, a lot of old business logic, and a practical need: build a new UI and improve code that had been running for years. At first, I thought an AI coding agent would help only with a small part of the work. Maybe some boilerplate, some REST work around the system, and a bit of help reading old ObjectScript.
In practice, it became much more than that.
This article is intended as a beginner level article for people that want to learn how to use OAuth2 in their web applications natively.
There is an accompanying video/demo that may be helpful here:
and you can reproduce this locally with the Open Exchange application attached.
OAuth (Open Authorization) 2.0 is a standard way to let one application call another application’s API without sharing a username and password.
Introduction — The Problem with AI Streaming in ObjectScript
Today, I would like to introduce a problem I encountered and the solution I found when integrating AI APIs into an ObjectScript application. My initial tests were successful, yet somewhat frustrating.
The HTTP call worked; the request was properly sent to my LLM APIs. But then, silence... a long wait. Eventually, the entire response arrived as a single block.
Technically, it worked, but the user experience was disappointing compared to a ChatGPT session.
How many times have we migrated an IRIS Instance to another machine, maybe even another version, and after a few days realized we forgot that one SSL Configuration critical for a Business Operations to work? Or maybe a credential, or a lonely class in a package by itself?
The simple solution is to make a checklist¹. A checklist of the entities we have to move. But simple checklists on Word documents are often forgotten, or just ignored.
