Mobile App Build Commands

Quasar CLI makes it incredibly simple to develop or build the final distributables from your source code.

Before we dive in, make sure you got the Cordova CLI installed.

$ npm install -g cordova

Developing

$ quasar dev -m [ios|android]

# ..or the explicit form:
$ quasar dev -m cordova -T [ios|android]

# ..or the longer form:
$ quasar dev --mode cordova --target [ios|android]

# using a specific emulator (--emulator, -e)
$ quasar dev -m ios -e iPhone-7
# or
$ quasar dev -m ios -e iPhone-X,com.apple.CoreSimulator.SimRuntime.iOS-12-2

# passing extra parameters and/or options to
# underlying "cordova" executable:
$ quasar dev -m ios -- some params --and options --here

However, if you wish to open the IDE (Android Studio / Xcode) and from there to manually select the emulator (or multiple ones simultaneously!) to run the dev app on it/them (or to run the dev app on a real mobile/tablet device):

$ quasar dev -m [ios|android] --ide

WARNING

In Android Studio, you will be greeted with a message recommending to upgrade the Gradle version. DO NOT UPGRADE GRADLE as it will break the Cordova project. Same goes for any other requested upgrades.

If you encounter any IDE errors then click on File > Invalidate caches and restart.

In order for you to be able to develop on a device emulator or directly on a phone (with Hot Module Reload included), Quasar CLI follows these steps:

  1. Detects your machine’s external IP address. If there are multiple such IPs detected, then it asks you to choose one. If you’ll be using a mobile phone to develop then choose the IP address of your machine that’s pingable from the phone/tablet.
  2. It starts up a development server on your machine.
  3. It temporarily changes the <content/> tag in /src-cordova/config.xml to point to the IP previously detected. This allows the app to connect to the development server.
  4. It defers to Cordova CLI to build a native app with the temporarily changed config.xml.
  5. Cordova CLI checks if a mobile phone / tablet is connected to your development machine. If it is, it installs the development app on it. If none is found, then it boots up an emulator and runs the development app.
  6. Finally, it reverts the temporary changes made to /src-cordova/config.xml.

WARNING

If developing on a mobile phone/tablet, it is very important that the external IP address of your build machine is accessible from the phone/tablet, otherwise you’ll get a development app with white screen only. Also check your machine’s firewall to allow connections to the development chosen port.

Enabling iOS modern build

By default, Xcode modern build for iOS is disabled due to Cordova issues. However, if you know what you are doing and you want to enable it, do so from /quasar.conf.js:

cordova: {
  noIosLegacyBuildFlag: true
}

The above applies also if you want to specify the build type in your “build.json”.

Building for Production

$ quasar build -m [android|ios]

# ..or the explicit form:
$ quasar build -m cordova -T [ios|android]

# ..or the longer form:
$ quasar build --mode cordova --target [ios|android]

# this skips .app or .apk creation and just fills in /src-cordova/www
$ quasar build -m [ios|android] --skip-pkg

# passing extra parameters and/or options to
# underlying "cordova" executable:
$ quasar build -m ios -- some params --and options --here
  • These commands parse and build your /src folder then overwrite /src-cordova/www then defer to Cordova CLI to trigger the actual native app creation.

  • Built packages will be located in /dist/cordova unless configured otherwise.

  • If you wish to skip the Cordova CLI packaging step and only fill /src-cordova/www folder:

$ quasar build -m [ios|android] --skip-pkg
  • Should you wish to manually build the final assets using the IDE (Android Studio / Xcode) instead of doing a terminal build, then:
$ quasar build -m [ios|android] --ide
