ngx-fastboot

ngx-fastboot is an Angular library for dynamically loading configuration at runtime, optimizing startup performance by lazy-loading providers. The current stable version is 2.1.0, released February 2025. It requires Angular 19 and Node >=20.10.0. Key differentiators: unlike typical static environment files, ngx-fastboot allows configurations to be loaded asynchronously via HTTP or custom sources and bundled into a separate chunk for faster initial loads. It provides fastBootstrapApplication, withProviders, and lazyRootComponent helpers. The library ships TypeScript types and follows Angular's standalone component pattern.
