Part 2: Running Monaca Debugger with Monaca CLI

Monaca Debugger is a powerful application for testing and debugging your Monaca applications on real devices in real time.

When developing Monaca apps on your local PC, assuming that the local PC is successfully paired with the Monaca Debugger, all changes made to the project files will be pushed into Monaca Debugger as soon as you save those changes.

Before getting started

Please install Monaca Debugger on your device.

Please refer to Monaca Debugger installation for other platforms.

Step 1: Pairing the Monaca Debugger with a local PC

To debug or test a local Monaca app, you need to pair your PC with the Monaca Debugger.

Before connecting the Monaca Debugger to a PC, please pay attention to the following points:

  1. Monaca Debugger and the PC have to be connected to the same network connection (LAN or Wi-Fi).

  2. Use the same Monaca account for both Monaca Debugger and the PC.

  3. Disable the PC’s firewall.

  1. In the terminal window, navigate to your project folder and run the monaca debug command to connect to the Monaca Debugger. Then, the Monaca CLI will wait for the requests from the debugger.

2. Launch the Monaca Debugger app and sign in using your Monaca account information. Make sure you are using the same account information as for the Monaca CLI.

3. A popup message asking you to pair the debugger with the PC will appear.

4. If the pairing is successful, your local project name will appear under Local Projects in the Monaca Debugger. However, if the pairing does not work, refer to Fail to pair the Monaca Debugger.

To stop debugging and to unpair the debugger and the computer, press Ctrl+c.

Step 2: Running a project on the Monaca Debugger

  1. From the local projects list in the Monaca Debugger, click on a project name to run it.

  2. Now the project should be running as shown in the screenshot below. Touch the back button in the debugger menu to go back to the project list screen.

Step 3: Real time update between the Monaca CLI and the debugger

  1. Run the project in the debugger.

  2. Try making some changes to a project file. For example, try changing the starting page of the sample app to Page 2. In order to do this, open the index.html file. Then, change the main-page attribute (inside <ons-sliding-menu> tag) to page2.html and save your changes. The updated code should look like this:

    side="left" type="overlay"
  3. If your PC is still connected to the Monaca Debugger, it will automatically refresh the updates. Now your starting page should be the page 2.

Please refer to Debugger functionalities to explore the other functions provided by the Monaca Debugger.

You can also use USB debugging with the Monaca CLI. Please refer to USB debugging with Monaca.

That’s it! Try to make more changes to your project and see how it runs in the debugger. Enjoy developing with Monaca!
