@wrnexus/mobile

SSR-safe compatibility access to Capacitor plugins.

Private registry access required

This package is not available from the public npm registry. After WorkRoot approves access and supplies private registry instructions, install the release-aligned package:

bun add @wrnexus/mobile@0.2.59

Request 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 or undefined; 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() and platform() 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/mobile re-exports native from @wrnexus/native for applications that

prefer the higher-level cross-platform capability API.

Examples

Examples are taken from this package's installed documentation and must be evaluated with its requirements and stability notes.

Register and invoke a Capacitor plugin

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

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" };
