The Heroku CLI is a vital tool for developers, providing a simple, extensible way to interact with the powerful features Heroku offers. We understand the importance of keeping the CLI updated to enhance user experience and ensure stability. With the release of Heroku CLI v10, we’re excited to introduce key changes that enhance the user experience and improve compatibility with the next-generation Heroku platform.
Heroku CLI v10 introduces several breaking changes, updates for Fir (the next-generation Heroku platform), and overall performance improvements. Here’s a breakdown of the key features:

What is pnpm?
Pnpm is a fast, disk-efficient Node package manager used as an alternative to npm. The Heroku Node.js buildpack now supports pnpm . Early Node.js application owners who’ve taken advantage of pnpm support have seen 10-40% faster install times compared to NPM on Heroku deployments. It’s an excellent choice for managing packages in the Node.js ecosystem because it: Minimizes disk space with its content-addressable package store. Speeds up installation by weaving together the resolve, fetch, and linking stages of dependency installation.
This post will introduce you to some of the benefits of the pnpm package manager and walk…

How to Build and Deploy a Node.js App That Uses OpenAI’s APIs
Near the end of 2023, ChatGPT announced that it had 100M weekly users. That’s a massive base of users who want to take advantage of the convenience and power of intelligent question answering with natural language.
With this level of popularity for ChatGPT, it’s no wonder that software developers are joining the ChatGPT app gold rush, building tools on top of OpenAI’s APIs. Building and deploying a GenAI-based app is quite easy to do—and we’re going to show you how!
In this post, we walk through how…

This blog post is adapted from a talk given by Julián Duque at NodeConf EU 2019 titled " Let it crash! ."
Before coming to Heroku , I did some consulting work as a Node.js solutions architect. My job was to visit various companies and make sure that they were successful in designing production-ready Node applications. Unfortunately, I witnessed many different problems when it came to error handling, especially on process shutdown. When an error occurred, there was often not enough visibility on why it happened, a lack of logging details, and bouts of downtime as…

Building a SaaS product, a system to handle sensor data from an internet-connected thermostat or car, or an e-commerce store often requires handling a large stream of product usage data, or events. Managing event streams lets you view, in near real-time, how users are interacting with your SaaS app or the products on your e-commerce store; this is interesting because it lets you spot anomalies and get immediate data-driven feedback on new features. While this type of stream visualization is useful to a point, pushing events into a data warehouse lets you ask deeper questions using SQL.
In this post, we’ll…

The CLI Team at Heroku strives to create a CLI user experience that is intuitive and productive. We had “build CLI autocomplete” in the icebox of our roadmap for many years. But if we were going to ship it, it had to complement the existing CLI experience. This is challenging because the Heroku CLI is very dynamic: it comprises user installable plugins, and the data needed for completions is behind an API.
Recently, we spent some time brainstorming the experience we wanted from Heroku CLI Autocomplete and decided it was time. We took “build autocomplete” out of the…

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…

Choices are an important part of a healthy open source software community. That’s why we’re excited about Yarn, a new package manager that addresses many of the problems with Node’s default package manager, npm . While npm has done a fantastic job creating a large and vibrant JavaScript ecosystem, I want to share why Yarn is an important addition to the Node.js ecosystem, how it will improve your Node.js development experience, and how Heroku has incorporated it into the build process for your Heroku apps.
We began testing Yarn almost immediately after it was released, and…

Today we are announcing the newest version of the Heroku CLI . We know how much time you spend in the CLI as developers and how much pride you take in being able to get things done quickly. Our new CLI has big improvements in performance as well as enhanced readability for humans and machines.
CLI response time is made up of two parts: the API response time and the performance of the CLI itself, and the latter is where we’ve made big improvements. While a typical Unix user should experience responses…

Heroku recently released [a managed Apache Kafka][1] offering. As a Node.js developer, I wanted to demystify Kafka by sharing a simple yet practical use case with the many Node.js developers who are curious how this technology might be useful. At Heroku we use Kafka internally for a number of uses including data pipelines . I thought that would be a good place to start.
When it comes to actual examples, Java and Scala get all the love in the Kafka world. Of course, these are powerful languages, but I wanted to explore Kafka from the perspective of Node.js. While there are…
