Decide whether to use eager, lazy, or hybrid loading for StencilJS components. Compare constraints, trade‑offs, and see a concrete example that validates on‑demand loading while keeping SSR and legacy browsers happy.
When a StencilJS app’s lazy‑loaded components fail in production, the root causes often lie in build config, base href, or server rewrite rules. This diagnostic guide walks through symptoms, checks, fixes, and escalation steps to help you pinpoint and resolve the issue quickly.
Learn how to enable component‑level lazy loading in StencilJS, verify the generated chunks, and understand when the trade‑off makes sense.
Learn how to split StencilJS components into lazy chunks, keep server‑rendered HTML interactive with hydration, and verify the design with build checks and browser devtools.
Learn when to use @Prop vs @State in StencilJS to avoid unidirectional data flow violations and unnecessary re-renders in your web components.
Author once in Stencil and emit Custom Elements plus React, Angular and Vue wrappers from one stencil.config.ts. Learn how to configure outputTargets, verify artifacts, and manage Shadow DOM and SSR trade-offs.
A Stencil component library builds locally but the deployment pipeline fails during stencil build , and the only visible signal is a non-zero exit code from the CLI. The goal is to reliably identify, from CI logs alone, whether the failure is a compiler diagnostic — such as the validation error raised when an @Component tag is not lowercase or contains no da
Managing Large Array Slices in Reactive Components Integrating a pagination pattern within a StencilJS component requires balancing the reactive state system with the performance of the Virtual DOM. When handling large datasets, the goal is to ensure that only a subset of the data is processed during the render cycle to prevent DOM bloat and browser lag. The
Internal vs External State: A Decision Point StencilJS offers two primary decorators for managing component data: @State for internal, encapsulated state, and @Prop for data supplied by a parent or via an HTML attribute. The choice between them hinges on ownership of the data and the desired data flow direction. When a component performs multiple updates—som
