# Platform & Delivery

Runtime configuration, Nx packages, build caches, bundles, versioning, and frontend deployment.

Runtime configuration, Nx packages, build caches, bundles, versioning, and frontend deployment.

## Articles

* [Runtime Config for Vite](/flutter/my-reactjs/platform-delivery/runtime-config-vite.md) — Build once, deploy the same artifact across environments with a strict, versioned public configuration boundary.
* [Runtime Config Startup Gate](/flutter/my-reactjs/platform-delivery/runtime-config-startup-gate.md) — Verify import ordering, prevent late mounts, and return cleanup ownership to the document.
* [Browser Config Is Public](/flutter/my-reactjs/platform-delivery/browser-config-is-public.md) — Select public fields, distinguish credentials, and check data reaching artifacts with a canary.
* [Package Boundaries in Nx](/flutter/my-reactjs/platform-delivery/nx-package-boundaries.md) — Assign meaningful roles, verify graph producers, and use negative controls to establish what the gate enforces.
* [Affected Builds and Nx Cache](/flutter/my-reactjs/platform-delivery/nx-affected-build-cache.md) — Establish the checkout, computation inputs, and restored outputs before sharing a cache through CI.
* [Package Versioning with Changesets](/flutter/my-reactjs/platform-delivery/changesets-package-versioning.md) — Review release scope, inspect partial changelog writes, and preserve artifact identity through publication.
* [Vite Chunks and Bundle Analysis](/flutter/my-reactjs/platform-delivery/vite-chunks-bundle-analysis.md) — Compare chunk graphs, emitted bytes and browser evaluation while respecting report boundaries.
* [Loading Libraries on Demand](/flutter/my-reactjs/platform-delivery/on-demand-library-loading.md) — Separate module loading from instance lifetimes, verify demand/cleanup, and retain distinct analytics policies.
* [Production Source Maps](/flutter/my-reactjs/platform-delivery/source-maps-production.md) — Match maps to frozen snapshots, separate public artifacts, and verify upload, origin, and stack evidence.
* [Traceable Build Metadata](/flutter/my-reactjs/platform-delivery/traceable-build-metadata.md) — Separate versions, revisions, and build IDs; minimize public labels and connect private records to final output.
* [Static Deployment and Caching](/flutter/my-reactjs/platform-delivery/static-deployment-caching.md) — Separate URLs/config/cache, verify assets before promotion, and retain dependencies for old tabs.
