run-ios

Description
Runs a MiniApp on an iOS simulator or connected device
Syntax
ern run-ios
Options
--baseComposite <compositePath>
Git or File System path, to the custom Composite repository (refer to the custom Composite documentation for more information).
--descriptor, -d
complete native application descriptor
--dev [true|false]
--extra/-e
Optional extra configuration specific to local container and runner
Override iOS configuration during local container generation and runner project by passing iosConfig attributes
As a json string
For example --extra '{"iosConfig": {"deploymentTarget": "11.0"}}'
Find more information on iOS configuration​
As a file path
For example --extra /home/user/my-container-config.json
In that case, the configuration will be read from the file.
As a Cauldron file path
For example --extra cauldron://config/container/my-container-config.json
In that case, the configuration will be read from the file stored in Cauldron.
For this way to work, the file must exist in Cauldron (you can add a file to the cauldron by using the [ern cauldron add file] command).
Find more information on configuring via cauldron​
Alternatively, it is also possible to provide this extra configuration in the package.json of the MiniApp, inside the ern object. For example:
"ern": {
  "iosConfig": {
    "deploymentTarget": "11.0"
  }
}
Optional hooks to run an arbitary script before or after js bundling is possible. 
If a script is defined as a preBundle hook, it will be executed after the composite generation, prior to running metro bundler, from the directory containing the generated composite project. 
As a json string
--extra '{"containerGenerator": {"hooks": {"preBundle": "/workspace/ern/picking-miniapp/script/pre-script.sh"}}}'
As a file path
--extra <path>/container-config.json
As a Cauldron file path
--extra cauldron://config/config.json
If a script is defined as a postBundle hook, it will be executed just after metro bundler has been run, from the directory containing the bundle.
As a json string
--extra '{"containerGenerator": {"hooks": {"postBundle": "/workspace/ern/picking-miniapp/script/post-script.sh"}}}'
As a file path
--extra <path>/container-config.json
As a Cauldron file path
--extra cauldron://config/config.json
Program to use to run the script should be indicated using shebang pattern in the script itself as first line.
Enable or disable React Native dev support
--host
Host or ip to launch the local packager on.
By default it will use the IP address that is returned by the ipconfig getifaddr en0 command, and fallback to localhost in the case the command fails.
--launchArgs
Arguments to pass to the application when launching it (correspond to the Arguments Passed On Launch in application scheme run config in Xcode as can be seen on screenshot below).
Make sure to use = on the command line to provide this option, and keep the string in quotes. For example --launchArgs="-ArgA -ArgB"
--launchEnvVars
Environment variables to pass to the application when launching it (correspond to the Environment Variables in application scheme run config in Xcode as can be seen on screenshot below).
Make sure to use = on the command line to provide this option, and keep the string in quotes. The string should contain key=value pairs delimited by spaces. For example --launchEnvVars="aKey=aValue anotherKey=anotherValue"
xcode scheme run
--mainMiniAppName
Name of the MiniApp to launch when starting the Runner application
--miniapps/m
One or more MiniApps to combine in the Runner Container
--port
Port on which the local packager should listen on (default: 8081)
--usePreviousDevice/-u
Use the previously selected device to avoid prompt
Remarks
You can launch the MiniApp located in the current working directory or on a connected iOS device or running emulator if available. If a connected iOS device is not available, the command prompts you to select an emulator to launch from the list of installed emulator images.
The first time you run this command from within a MiniApp directory, it generates an iOS directory containing the iOS Runner application project. If the iOS folder already exists (it is not the first run of the ern run-ios command for this MiniApp), the existing runner project is used.
After the runner project is generated, you can safely make native code modifications to it, knowing that the next time the ern run-ios command is issued, the project and your changes will remain.
If you want to regenerate the runner project from scratch, remove the iOS directory.
The miniapp can be any Yarn package descriptor, including Git or other file system path schemes.
The ern run-ios command is the ern equivalent of the react-native run-ios command.
