Learn how to implement custom Capacitor plugins to bridge JavaScript and native Swift/Java code, including thread management and data transfer best practices.
Goal: Migrate a small Ionic Angular application to a newer version of Capacitor while using Ionic App Flow live updates to achieve zero‑downtime deployment. Constraints: The live update must keep the existing web bundle compatible with the native runtime and any Capacitor plugins that are being upgraded. Uncertainty exists around how to detect and resolve ve
Capacitor allows for global application settings within the capacitor.config.ts file, including the ability to define platform-specific overrides to differentiate behavior between iOS and Android. While global settings are straightforward, there is uncertainty regarding the scope of these overrides when interacting with native plugin registrations. Specifica
Ionic/Capacitor Integration Boundary The goal is to ensure application stability when migrating Ionic applications across major framework versions while maintaining native plugin functionality. Constraint Uncertainty The resilience of the integration boundary is uncertain because rollback is managed externally, not by the Ionic framework itself. When perform
Goal Persist user data in a Capacitor 5.0+ web build by using the explicit @capacitor/storage API, since the implicit localStorage fallback has been removed. Uncertainty The plugin’s behavior when storing values that exceed native platform limits is not documented. On Android, SharedPreferences imposes a ~4 KB ceiling, while iOS NSUserDefaults limits are les
Capacitor plugin not found when calling from shared web code The goal is to run a Capacitor‑based app in web browsers and debug native builds without committing production credentials. The main uncertainty lies in how direct imports of native plugins in shared TypeScript code affect web execution. When a plugin that exists only on iOS or Android is imported
Two layers, no automatic undo A Capacitor upgrade touches two layers: the npm packages ( @capacitor/core , @capacitor/cli , and the platform packages) and the native ios/ and android/ projects, updated through the documented sync step that copies web assets and plugin configuration. Because those native directories are real, editable projects, there is no bu
Native HTTP Request Lifecycle Management Ionic applications utilizing the Capacitor HTTP plugin to bypass CORS and improve performance rely on native bridge calls for network operations. While this provides native performance, it introduces a discrepancy in how asynchronous requests are managed compared to the standard browser Fetch API. A primary challenge
In a Capacitor application, developers often face inconsistencies when the WebView serves stale data despite Cache-Control: no-cache headers. To resolve this, the Capacitor HTTP plugin can be used to shift network requests from the browser's fetch or XHR APIs to the native OS networking libraries. While native requests generally bypass the internal WebView c
