Capacitor 3.0 Upgrade Plugins “not implemented” Exception (Nx Monorepo)

Capacitor 3.0 Upgrade Plugins “not implemented” Exception (Nx Monorepo)

This article will guide you through troubleshooting and resolving the “not implemented” exception encountered during Capacitor 3.0 plugin upgrades within an Nx monorepo environment.

Understanding the Issue

When upgrading to Capacitor 3.0, you may encounter plugin-related exceptions like “not implemented” due to changes in the plugin API.

Root Causes

• Plugin API Incompatibility: Capacitor 3.0 introduced breaking changes to plugin APIs, requiring updates for compatibility.
• Plugin Version Mismatch: Older plugin versions might not be compatible with the latest Capacitor core.
• Nx Configuration Issues: The Nx workspace configuration may need adjustments to accommodate Capacitor 3.0.

Troubleshooting Steps

1. Update Capacitor and Plugins

• Upgrade Capacitor to 3.0 or the latest version.
• Update all Capacitor plugins to their latest compatible versions.

npm install --save @capacitor/core@3.0.0
npm install --save @capacitor/cli@3.0.0
npm install --save @capacitor/your-plugin@latest

2. Check for Plugin API Changes

• Consult the Capacitor 3.0 release notes for plugin API changes: Capacitor 3.0 Release Notes.
• Update your plugin implementations based on the revised API.

3. Verify Plugin Compatibility

• Confirm that your plugins support the Capacitor version you are using.
• Review plugin documentation for compatibility details.

4. Review Nx Workspace Configuration

• Check if the “capacitor” preset in your Nx workspace is configured correctly for Capacitor 3.0.
• Ensure plugin paths and configurations are accurate.

// nx.json
{
  "projects": {
    "your-app": {
      "targets": {
        "build": {
          "executor": "@nx/capacitor:build",
          "options": {
            "capacitorConfig": "capacitor.config.json" // Ensure the path is correct
          }
        }
      }
    }
  }
}

Example Scenario

Let’s imagine you have a Capacitor plugin “MyPlugin” and are getting the “not implemented” error when calling “MyPlugin.someFunction().”

Troubleshooting

• Check if “someFunction()” is still available in the updated “MyPlugin” API.
• Update your code to use the new API if necessary. Refer to the plugin documentation or release notes.
• Verify “MyPlugin” is compatible with Capacitor 3.0 by reviewing its package information.

Conclusion

By following these steps, you can effectively debug and resolve the “not implemented” exceptions associated with Capacitor 3.0 plugin upgrades in Nx monorepo projects. Keep your Capacitor core and plugins updated, check for API changes, and verify configurations for a smooth transition.
