checkout-ui-extensions-run

This package provides a command line interface for developing and building Checkout UI Extensions.

Installation

``bash
$ yarn add @shopify/checkout-ui-extensions-run --dev
`

Usage

This package will add a checkout-ui-extensions-run binary to your project. You can execute this binary directly, or through yarn:

`bash
$ node_modules/.bin/checkout-ui-extensions-run
$ yarn checkout-ui-extensions-run
`

$3

> alias: checkout-ui-extensions-run serve

`bash
$ yarn checkout-ui-extensions-run dev
`

This command will start a local development server for your extension. This development server, based on webpack-dev-middleware, will serve the JavaScript file for your extension, and will recompile it as you make changes to your codebase.

This command will print the localhost address of the asset server when it starts up. To control the port the server will bind to, you can pass the --port flag:

`bash
$ yarn checkout-ui-extensions-run dev --port 3000
`

$3

During development, the dev server exposes a /data endpoint which serves the api_key entry of the .env file and a json-parsed version of the extension.config.yml.

This endpoint is consumed by a browser extension, that we share with partners, which makes it easier to test locally developed post purchase extensions.

$3

`bash
$ yarn checkout-ui-extensions-run build
`

This command will run your extension through webpack to produce a highly-optimized asset. Once generated, the estimated size of the asset will be printed to the console.

The extension asset will be placed in the build directory adjacent to the directory in which you ran the command. By default, its name will be main.js, but this can be customized using the --filename flag:

`bash
$ yarn checkout-ui-extensions-run build --filename extension.js
