Delivery spend, engineered down

React Native Evals tests coding models on real React Native tasks. This article follows one automated run from model selection through solving, judging, result tracking, and human review.

Expo Updates used to be a pain point for teams running an Isolated Brownfield architecture. This guide shows how to get it working with Expo SDK 55, including iOS packaging, the current Android workaround, and end-to-end OTA update testing. If you're shipping React Native inside an existing native app, this walkthrough helps you get setup faster without guessing through the hard parts.

This article walks through the full release flow for React Native apps on Meta Quest, from preparing a production build to submitting it through the Horizon Store. Developers will learn the technical steps, required tools, and best practices for store‑ready assets. It also highlights common review pitfalls, guidance for creating high‑quality screenshots, monetization options, and tips for shaping a smooth submission workflow. By the end, readers will understand how to take a Quest app from development to a polished, store‑ready release.

Re.Pack 5.2 is out! This release focuses on parallel, smarter transforms with a new Babel & SWC loader, official support for React Native 0.80 and 0.81, fully typed configs, support for Rozenite and more.

One of the core reasons we built Rock was to eliminate unnecessary native iOS and Android builds by reusing existing artifacts: saving time, compute, and cost. Until now, remote caching was tied to GitHub, which limited flexibility. The latest release changes that: Rock now supports AWS S3 and Cloudflare R2, allowing teams to store and retrieve native builds from their own infrastructure. This unlocks a much more powerful setup for enterprise teams with custom CI or compliance needs.

Building large React Native apps can be challenging, with slow build times, complex integrations, and mixed tech stacks. We're developing a new framework designed for enterprise apps that optimizes build reuse, CI speed, and cloud integration while staying flexible and self-hosted.

Continuous Deployment (CD) lets you automate the critical steps of building, testing, and releasing your mobile apps. This guide walks through setting up CD pipelines with fastlane and AppCenter to ship new features and fixes faster without the manual toil.

Shipping critical updates to mobile apps can be painfully slow, but React Native's over-the-air (OTA) updates let you push fixes directly to users in minutes. We walk through how to set up OTA updates with App Center/CodePush or EAS Update to deploy changes instantly when you need them most.

Fastlane is a powerful tool for automating development tasks, but it has some nuances. This guide shares practical tips for reliably updating plist files in iOS projects and passing custom properties to Gradle builds in Android apps.

Continuous Integration (CI) can help React Native teams ship faster and with more confidence. By automating builds and tests, CI provides quick feedback on code changes, catches regressions early, and reduces manual testing effort. This article explores how to set up CI for React Native apps using popular tools like CircleCI and EAS Build.

Continuous integration and delivery can be tricky to set up, especially for mobile apps. This guide walks through a real-world example of configuring CircleCI, Fastlane, and App Center to automate builds, tests, code quality checks, and beta distribution for a React Native app.
