WooCommerce Packages

Currently we have a small set of public-facing packages that can be dowloaded from npm and used in external applications.

• @woocommerce/components: A library of components that can be used to create pages in the WooCommerce dashboard and reports pages.
• @woocommerce/csv-export: A set of functions to convert data into CSV values, and enable a browser download of the CSV data.
• @woocommerce/currency: A class to display and work with currency values.
• @woocommerce/date: A collection of utilities to display and work with date values.
• @woocommerce/navigation: A collection of navigation-related functions for handling query parameter objects, serializing query parameters, updating query parameters, and triggering path changes.
• @woocommerce/tracks: User event tracking utility functions for Automattic based projects.

Working with existing packages

• You can make changes to packages files as normal, and running pnpm start will compile and watch both app files and packages.
• ⚠️ Make sure any dependencies you add to a package are also added to that package's package.json, not just the woocommerce-admin package.json
• ⚠️ Make sure you're not importing from any woocommerce-admin files outside of the package (you can import from other packages, just use the import from @woocommerce/package syntax).
• Add your change to the CHANGELOG for that package under the next version number, creating one if necessary (we use semantic versioning for packages, see these guidelines).
• Don't change the version in package.json.
• Label your PR with the Packages label.
• Once merged, you can wait for the next package release roundup, or you can publish a release now (see below, "Publishing packages").

Creating a new package

Most of this is pulled from the Gutenberg workflow.

To create a new package, add a new folder to /packages, containing…

1. package.json based on the template:

   {
   	"name": "@woocommerce/package-name",
   	"version": "1.0.0-beta.0",
   	"description": "Package description.",
   	"author": "Automattic",
   	"license": "GPL-2.0-or-later",
   	"keywords": [ "wordpress", "woocommerce" ],
   	"homepage": "https://github.com/woocommerce/woocommerce/tree/main/packages/[_YOUR_PACKAGE_]/README.md",
   	"repository": {
   		"type": "git",
   		"url": "https://github.com/woocommerce/woocommerce.git"
   	},
   	"bugs": {
   		"url": "https://github.com/woocommerce/woocommerce/issues"
   	},
   	"main": "build/index.js",
   	"module": "build-module/index.js",
   	"react-native": "src/index",
   	"publishConfig": {
   		"access": "public"
   	}
   }

2. .npmrc file which disables creating package-lock.json file for the package:

   package-lock=false
   

3. README.md file containing at least:

   • Package name
   • Package description
   • Installation details
   • Usage example

4. A src directory for the source of your module, which will be built by default using the pnpm run build:packages command. Note that you'll want an index.js file that exports the package contents, see other packages for examples.

5. Add the new package name to packages/dependency-extraction-webpack-plugin/assets/packages.js so that users of that plugin will also be able to use the new package without enqueuing it.

Publishing packages

• Run pnpm run publish-packages:check to run pnpm publish with the --dry-run option
• Create a PR with a CHANGELOG for each updated package (or try to add to the CHANGELOG with any PR editing packages/)
• Run pnpm run publish-packages:prod to publish the package
• OR Run pnpm run publish-packages:dev to publish "next" releases (installed as pnpm i @woocommerce/package@next). Only use :dev if you have a reason to.
• Both commands will run build:packages before the publishing task, just to catch any last updates.

Publishing a single package

Sometimes, its helpful to release a singular package. This can be done directly through pnpm. Be sure versions and builds are correct.

• Bump the version in the package's package.json as well as its CHANGELOG file.
• pnpm install && pnpm run build:packages to build packages.
• cd packages/<package-name>
• pnpm publish
