Electron on Heroku

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…

How to Use pnpm on Heroku

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…

Building a Monorepo with Yarn 2

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…

Let’s Debug a Node.js Application

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…

Reactive Programming with Salesforce Data

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 .

Evolution of the Heroku CLI: 2008-2017

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?

Habits of a Happy Node Hacker 2017

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.…

Deploying React with Zero Configuration

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…

Tom Dale on Ember FastBoot and Scrappy JavaScript

Last week, Terence Lee and I caught up with Tom Dale at EmberConf to talk about FastBoot, when you should avoid native apps, and why JavaScript on the server and the browser might start to converge. Check the end for the full recording! So let’s start with the drama, would you say Ember has declared war on native apps? [laughs] [sigh] Yeah. Yeah, I think that’s fair. Yeah. Sure. Why not? Let’s go with that. A lot of other frameworks, take this approach of bringing web technologies and dropping them into native experiences – React Native being the…

How to Deploy Your Slack Bots to Heroku

Whether they're publishing notifications, responding to /slash commands or carrying a conversation, bots have become an integral part of the way we work with Slack. A bot can do any number of things for your team as part of your day-to-day work, you're only limited by your imagination. For some first-hand experience, check out the Heroku Button Gallery , where users have created all types of bots: from fun bots like poker and Jeopardy! , to more practical ones like a bot that tracks the satisfaction of your team members or one that reminds your team…
