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 endpoints. And in this…

JavaScript turns 25 years old today. While it’s made an impact on my career as a developer, it has also impacted many developers like me and users around the world. To commemorate our favorite language, we’ve collected 25 landmark events that have shaped the path of what the JavaScript ecosystem looks like today. 1995 1) JavaScript is created In 1995, Brendan Eich, a developer at Netscape, known for their Netscape browser, was tasked with building a client-side scripting language that paired well with Java.

The following is the story of how Randall Degges created a simple API to solve the common problem of external IP address lookup and how he scaled it from zero to over 10 thousand requests per second (30B/month!) using Node.js and Go on Heroku. Several years ago I created a free web service, ipify. It is a highly scalable IP address lookup service. When you make a GET request against it, it returns your public-facing IP address. Try it out yourself! I created ipify because, at the time, I was building complex infrastructure management software and needed to dynamically discover…
So you want to build an app with React? "Getting started" is easy… and then what? React is a library for building user interfaces, which comprise only one part of an app. Deciding on all the other parts — styles, routers, npm modules, ES6 code, bundling and more — and then figuring out how to use them is a drain on developers. This has become known as javascript fatigue. Despite this complexity, usage of React continues to grow. The community answers this challenge by sharing boilerplates. These boilerplates reveal the profusion of architectural choices developers must make. That official "Getting…
Three months ago we announced that Parse would be opening their Cloud Code product so that their customers would be able to deploy their mobile backends to Heroku. This allowed Parse customers to use a full Node.js environment with Cloud Code. With Parse’s recent announcement, we’re taking that one step further, by allowing you to deploy your own Parse API server to Heroku. What this means for developers is that you will now be able to run all of your Parse services on Heroku, taking advantage of Heroku’s scalable platform as well as Heroku features like Pipelines, Review Apps, and…
