DevMate CLI for React Native Development

1 post · Oct 2025

What this trail covers

Atlassian's Mobile Platform team developed DevMate, an in-house CLI tool to accelerate React Native development. DevMate streamlines environment setup, reduces build times, and improves consistency by automating dependency installation, intelligent dependency management, and smart build skipping. It addresses challenges like complex environment setup, inconsistent workflows, long build times, cross-platform testing overhead, and onboarding friction. DevMate complements existing tools like Expo CLI and React Native CLI by providing native-aware features tailored for Atlassian's internal workflows.

  1. DevMate: Accelerating React Native Development at AtlassianThis post introduces DevMate, an in-house CLI tool designed to accelerate React Native development at Atlassian. It details the challenges faced during the Confluence Mobile app migration, including complex environment setup, inconsistent workflows, long build times, and cross-platform testing friction. The solution, DevMate, is presented with its core features: automated environment setup using a dependency chain and common interface, intelligent dependency management via file hashing, and smart build skipping by tracking native file modification times. The technical implementation is described using TypeScript and Bash, highlighting patterns like dependency interfaces, two-tier hash-based change detection, and platform abstraction. The impact is measured through reductions in onboarding time, build times, dependency-related errors, and improvements in developer satisfaction.
