React Native & Expo applications

What it is

Products written in React Native and packaged through Expo and its build service, with over-the-air updates for script-only changes and native code in the project once the app outgrows the managed workflow.

Why businesses need it

This stack moves quickly, and a version behind is where the awkward bugs live. Expo removes most of the native build pain and then needs deliberate unescaping; knowing which side of that line an app is on is the work.

What MIWEBX delivers

• New React Native applications in TypeScript on a current stable version
• Expo configuration, development builds and store-ready production builds
• Upgrades: framework version steps, SDK bumps and the dependency work around them
• Migration from the managed workflow to bare when a native module requires it
• Custom native modules and configuration plugins for the SDKs the app needs
• Recovery of an existing app stalled on an old framework version

Core features

• Build, submit and update channels configured in the project rather than on one laptop
• Over-the-air update tracks split by environment, with a rollback path
• Development builds carrying the native dependencies the app really uses
• Typed navigation and screen props, so a route change fails at build time
• Interface rendered by the platform's own views rather than a WebView, so lists and gestures stay smooth
• Accessibility labels and focus order checked on both platforms

Technical capabilities

• Expo build and submit service wired into the repository and the CI pipeline
• Update channels and per-version rollouts, with the caveat that native changes still need a binary release
• Autolinking and configuration plugins for third-party native SDKs on both platforms
• Renderer and bridge-mode decisions made explicitly rather than inherited from a template
• Optimised script bundles with source-mapped crash traces
• Upgrade rehearsed on its own branch: dependencies first, then the native build, then store artefacts
• Push registration against APNs and FCM from one shared notification service

How we build it

• Baseline the current SDK and framework versions, and what is blocking an upgrade.
• Get a development build running on a real device before touching features.
• Build the screens and state layer against typed API contracts.
• Configure builds, submission and update channels so a release is a command.
• Do the version upgrade on its own branch, with native build failures fixed before merge.
• Release binary and over-the-air updates on separate tracks, with crash health in between.

Technology stack

• React
• React Native
• Expo
• TypeScript
• Node.js
• App Store / Play Store
• Push notifications (APNs / FCM)
• Sentry-class crash reporting

What you receive

• Repository with Expo configuration, build profiles and credential handling documented
• Working development, preview and production environments on device
• Store-ready builds produced and submitted through the configured pipeline
• Update channels set up, with the rollback procedure written down
• An upgrade note: current versions, what comes next and what it will cost

Business benefits

• The stack stays current, so each upgrade gets cheaper rather than harder
• Script-level fixes reach users between store releases
• Anyone on the team can produce a release build, not only the person who set it up
• One skill set covers the app and the web product, which makes the team easier to staff
