@wrnexus/mobile
SSR-safe compatibility access to Capacitor plugins.
Install the package
After WorkRoot approves private registry access, install the release-aligned package:
bun add @wrnexus/mobile@0.2.65Request preview access. Never put registry tokens in source control.
SSR-safe access to Capacitor plugins from WRNexusJS browser code.
Overview
@wrnexus/mobile keeps optional native imports out of server rendering while giving browser-owned modules one consistent registry for Capacitor plugins. During SSR, mobile.isNative() is false and mobile.platform() is "web".
Install a plugin through the WRNexusJS CLI so the web and native projects stay aligned:
wrnexus mobile add @capacitor/camera @capacitor/haptics
Usage
Register and invoke a Capacitor plugin
Import Capacitor packages only from browser-owned code, never from API routes or SSR helpers.
import { Camera, CameraResultType } from "@capacitor/camera";
import { mobile } from "@wrnexus/mobile";
mobile.registerPlugin("Camera", Camera);
export async function takePhoto() {
if (!mobile.isNative()) return null;
return mobile.invoke("Camera", "getPhoto", {
quality: 85,
resultType: CameraResultType.Uri,
});
}
Provide a browser fallback
whenNative runs the first callback only in a Capacitor WebView and can return a web/SSR-safe fallback everywhere else.
import { Haptics, ImpactStyle } from "@capacitor/haptics";
import { mobile } from "@wrnexus/mobile";
mobile.registerPlugin("Haptics", Haptics);
export const confirmAction = () =>
mobile.whenNative(
() => mobile.invoke("Haptics", "impact", { style: ImpactStyle.Medium }),
() => navigator.vibrate?.(30),
);
Read an optional plugin without throwing
import type { NetworkPlugin } from "@capacitor/network";
import { mobile } from "@wrnexus/mobile";
const network = mobile.plugin<NetworkPlugin>("Network");
const status = network ? await network.getStatus() : { connected: true, connectionType: "unknown" };
API
registerPlugin(name, instance)registers a browser-imported plugin.plugin(name)returns a plugin orundefined;requirePlugin(name)throws when absent.invoke(plugin, method, options?)calls a registered method and returns its result.whenNative(native, fallback?)selects native behavior without breaking SSR.isNative()andplatform()report the current Capacitor environment.
Unavailable required plugins throw MobileUnavailableError with an actionable message.
Requirements / Notes
- Capacitor plugin imports must remain in browser-owned modules.
@wrnexus/mobilere-exportsnativefrom@wrnexus/nativefor applications that
prefer the higher-level cross-platform capability API.
