Building a GPT Backed by a Heroku-Deployed API

How to connect your GPT on OpenAI to a backend Node.js app

Late in 2023, OpenAI introduced GPTs , a way for developers to build customized versions of ChatGPT that can bundle in specialized knowledge, follow preset instructions, or perform actions like reaching out to external APIs. As more and more businesses and individuals use ChatGPT, developers are racing to build powerful GPTs to ride the wave of ChatGPT adoption. Source If you’re thinking about diving into GPT development, we’ve got some good news: Building a powerful GPT mostly involves building an API that handles a few…

Plans to Re-enable the GitHub Integration

[ Update: May 25, 2022 – GitHub integration is now re-enabled. You can connect to GitHub immediately or wait for the enhanced integration as described below. To re-establish your GitHub connection now, please follow these instructions .]

We know you are waiting for us to re-enable our integration with GitHub, and we’ve committed to you that we would only do so following a security review. We are happy to report that the review has now been completed.

One of the areas of focus was a review of the scope of tokens we request from GitHub and store on your behalf. Currently, when…

How We Added Client Rate Throttling to the Platform API Gem

When API requests are made one-after-the-other they’ll quickly hit rate limits and when that happens:

That tweet spawned a discussion that generated a quest to add rate throttling logic to the platform-api gem that Heroku maintains for talking to its API in Ruby.

If the term “rate throttling” is new to you, read Rate limiting, rate throttling, and how they work together…

Building a GraphQL API in JavaScript

Over the last few years, GraphQL has emerged as a very popular API specification that focuses on making data fetching easier for clients, whether the clients are a front-end or a third-party.

In a traditional REST-based API approach, the client makes a request, and the server dictates the response:
$ curl https://api.heroku.space/users/1

{
“id”: 1,
“name”: “Luke”,
“email”: “luke@heroku.space”,
“addresses”: [
{
“street”: “1234 Rodeo Drive”,
“city”: “Los Angeles”,
“country”: “USA”
}
]
}

But, in GraphQL, the client determines precisely the data it wants…

New Review Apps: Expanded Options for Greater Control, Automation, and Access

Faster application delivery with remote teams is the key to connect with your customers, now more than ever. A few years ago, we released Review Apps with the goal of improving the application development process and team collaboration. Today, we are excited to announce the release of an improved version of Review Apps to general availability.

The new version of Review Apps provides easier access management with a new permission system, and more flexibility for complex workflows with public APIs. It also no longer needs a staging, production, or placeholder app to host its configuration and collaborator access; this independence supports…

Saved by the Schema: Using JSON Schema to Document, Test, and Debug APIs

Heroku has many public API endpoints. Each of these endpoints needs to be tested so that we know how they work, and documented so that our customers (and other API consumers) know how they work. Follow along, and we’ll learn how Heroku uses JSON Schema to test and document our Platform API – and how it helped us uncover an unexpected bug, rooted in the way the Oj gem parses Big Decimals.

JSON Schema files are like blueprints that define the structure and semantics of other JSON documents. When a JSON Schema file is applied to a JSON document, you can…

Beyond Web and Worker: Evolution of the Modern Web App on Heroku

This is the first in a series of blog posts examining the evolution of web app architecture over the past 10 years. This post examines the forces that have driven the architectural changes and a high-level view of a new architecture. In future posts, we’ll zoom in to details of specific parts of the system. The standard web application architecture suitable for many organizations has changed drastically in the past 10 years. Back in Heroku’s early days in 2008, a standard web application architecture consisted of a web process type to respond to HTTP requests, a database to persist…
