create-miniapp

Description

• Create a new MiniApp in a new directory named after the MiniApp.

The generated MiniApp is a starter HelloWorld MiniApp that you can use to launch a standalone MiniApp on the iOS or Android platforms in our Runner—using the ern run-ios and ern run-android commands.

If you used react-native previously, you'll notice that the generated JavaScript react-native MiniApp is exactly the same react-native starter app as the one provided by react-native. A MiniApp is simply a react-native application. One of the differences with react-native is that we generate our own native projects which use a locally-generated ern container.

iOS and Android directories are not generated by this command. To generate those directories, run the ern run-ios or ern run-android commands.

Syntax

ern create-miniapp <appName>

Arguments

<appName>

• The name to use for the MiniApp. The MiniApp name must follow Electrode Native module name rules.

• We recommend suffixing the name of MiniApp with suffix App

Options

--language <TypeScript | JavaScript>

• Language to use for this MiniApp (either TypeScript or JavaScript)

• Default The command will prompt for language to use.

--scope/-s <scope>

• Specify the NPM package scope to use for the MiniApp.

• Add the package scope automatically in the package.json of the generated MiniApp.

• Default Package will be unscoped.

--packageManager <'npm' | 'yarn'>

• The package manager to be used with this MiniApp (npm or yarn)

• This will set ern.packageManager in the MiniApp package.json.

• This setting will only be used for ern add and ern upgrade-miniapp commands. It won't apply for creating the MiniApp. Electrode Native is internally running react-native init command which uses yarn by default, if available on the machine, when creating an app. react-native does not offer this to be configured as of now. If you wish to use npm, you will have to manually remove the yarn.lock / node_modules in the MiniApp directory after creation, and run npm install.

• Default The command will prompt for the package manager to use.

--packageName/-p <name>

• Specify the NPM package name to use for the MiniApp.

• Add the package name automatically in the package.json of the generated MiniApp.

• Default The command will prompt for the package name to use.

--platformVersion/-v <version>

• Specify a platform version if different from the currently activated version.

• This option is rarely used.

• Default Will use the currently activated platform version.

--skipNpmCheck

• Skip the check ensuring package does not already exists in NPM registry.

• Default The value defaults to false.

--manifestId <manifestId>

• Id of the override Manifest entry to retrieve dependencies versions from (see [override Manifest] for more info)

--template <template>

• The React Native project template to use.

• Internally, Electrode Native will forward this template to 'react-native init' command.

• Electrode Native will perform same post processing as it does on non templated MiniApps, once MiniApp is created (add 'ern' object to the package.json of the MiniApp and remove android and ios directories).

Examples

ern create-miniapp MyAwesomeApp

Creates a MiniApp named MyAwesomeApp.

ern create-miniapp MyAwesomeApp --scope MyCompany

Creates a MiniApp named MyAwesomeApp and use MyCompany as the scope of the MiniApp NPM package.

ern create-miniapp MyAwesomeApp --packageName my-awesome-app

Creates a MiniApp named MyAwesomeAp and use my-awesome-app as the name of the MiniApp NPM package.

Remarks

• MiniApp name can only consist of upper and lower case characters. No digits nor special characters can be used.

• Package name should be a valid NPM package name.

• This command is the ern equivalent of the react-native init command.
