As maintainers of the open source framework Electron, we try to be diligent about the work we take on. Apps like Visual Studio Code, Slack, Notion, or 1Password are built on top of Electron and make use of our unique mix of native code and web technologies to make their users happy. That requires focus: There’s always more work to be done than we have time and resources for. In practice, that means that we don’t want to spend time thinking about the server infrastructure for the project — and we’re grateful for the support we receive from Heroku, where…

Intro The Heroku Node.js buildpack now supports pnpm, an alternative dependency manager. 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 you through creating and deploying a sample application. Prerequisites Prerequisites for this include:…

In true JavaScript fashion, there was no shortage of releases in the JavaScript ecosystem this year. This includes the Yarn project’s release of Yarn 2 with a compressed cache of JavaScript dependencies, including a Yarn binary to reference, that can be used for a zero-install deployment. Yarn is a package manager that also provides developers a project management toolset. Now, Yarn 2 is now officially supported by Heroku, and Heroku developers are able to take advantage of leveraging zero-installs during their Node.js builds. We’ll go over a popular use case for Yarn that is enhanced by Yarn 2: using workspaces…

There are always challenges when it comes to debugging applications. Node.js' asynchronous workflows add an extra layer of complexity to this arduous process. Although there have been some updates made to the V8 engine in order to easily access asynchronous stack traces, most of the time, we just get errors on the main thread of our applications, which makes debugging a little bit difficult. As well, when our Node.js applications crash, we usually need to rely on some complicated CLI tooling to analyze the core dumps. In this article, we'll take a look at some easier ways to debug your…

The recent introduction of Platform Events and Change Data Capture (CDC) in Salesforce has launched us into a new age of integration capabilities. Today, it's possible to develop custom apps that respond to activity in Salesforce. Whether you're creating a memorable customer interaction or implementing an internal workflow for employees, consider an event-sourced design to improve responsiveness and durability of the app. In this article, we'll look at an event-sourced app architecture that consumes the Salesforce Streaming API using the elegant jsforce JavaScript library in a Node app on Heroku. Streaming with jsforce In summer 2018, the open-source jsforce library…

Over the past decade, millions of developers have interacted with the Heroku CLI. In those 10 years, the CLI has gone through many changes. We've changed languages several times; redesigned the plugin architecture; and improved test coverage and the test framework. What follows is the story of our team's journey to build and maintain the Heroku CLI from the early days of Heroku to today. Ruby (CLI v1-v3) Go/Node (CLI v4) Go/Node (CLI v5) Pure Node (CLI v6) What's Next? Ruby (CLI v1-v3) Our original CLI (v1-v3) was written in Ruby and served us well for many years. Ruby is…

It’s been a little over a year since our last Happy Node Hackers post, and even in such a short time much has changed and some powerful new tools have been released. The Node.js ecosystem continues to mature and new best practices have emerged. Here are 8 habits for happy Node hackers updated for 2017. They're specifically for app developers, rather than module authors, since those groups have different goals and constraints: 1. Lock Down Your Dependency Tree In modern Node applications, your code is often only the tip of an iceberg. Even a small application could have thousands of…

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 began fully supporting it on…

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. Tuned for Performance 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 that are around half a second…
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…
