Simplifying JVM App Development with Heroku’s Buildpack Magic

Heroku’s commitment to developer productivity shines through in its powerful buildpack system . They handle the heavy lifting of building your app, letting you focus on what matters most: writing code. A prime example is the Heroku Java buildpack , a versatile tool that simplifies deploying Java applications, especially those built with popular frameworks like Spring Boot, Quarkus, and Micronaut.

One of the core strengths of Heroku buildpacks is their automatic nature. They intelligently detect your application’s language and framework, fetching the necessary build tools and configuring the Heroku platform to run your app seamlessly. This means no more wrestling with…

Turn Your Code into Docker Images with Cloud Native Buildpacks

When we open-sourced buildpacks nearly seven years ago, we knew they would simplify the application deployment process. After a developer runs git push heroku master, a buildpack ensures the application’s dependencies and compilation steps are taken care of as part of the deploy. As previously announced , we’ve taken the same philosophies that made buildpacks so successful and applied them towards creating Cloud Native Buildpacks (CNB), a standard for turning source code into Docker images without the need for Dockerfiles. In this post, we’ll take a look at how CNBs work, how they aim to solve many of the problems…

PWA Tutorial: Turn Your Website Into a Progressive Web App

Progressive web apps (or PWAs) enable websites to function more like native mobile apps in exchange for some flexibility. You get cross-platform native mobile app functionality (or close to it) without all the overhead of app store approvals and tons of platform-specific native code.

Users can install a progressive web app to their home screen and launch it just like a native app. However, the app is launched into a pseudo-app frame that has some restrictions and only allows access to pages that are sub-paths of the initial path of the progressive web app. They also must be served over…

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…
