# Contributing
Thanks for your interest in contributing to WooCommerce Blocks! Below are some developer docs for working with the project.
2019-08-12 11:48:58 +00:00
To get started you need to install all required dependencies by running the following command in the plugin directory.
2019-08-12 11:48:58 +00:00
```bash
npm install && composer install
```
2019-08-12 11:48:58 +00:00
## NPM commands
2019-08-12 11:48:58 +00:00
We have a set of scripts in npm to automate important developer tasks.
2019-08-12 11:48:58 +00:00
### Build
- Run `$ npm run build` to build all assets for production.
2019-08-12 11:48:58 +00:00
- Run `$ npm start` to run the development build and watch for changes.
These scripts compile the code using `webpack`.
You can also run `$ npx webpack` to run the development build and not keep watching.
2019-08-12 11:48:58 +00:00
### Lint
Run `$ npm run lint` to check code against our linting rules.
This script runs 3 sub-commands: `lint:php`, `lint:css`, `lint:js`. Use these to run linters across the codebase (linters check for valid syntax).
- `lint:php` runs phpcs via composer, which uses the [phpcs.xml](https://github.com/woocommerce/woocommerce-gutenberg-products-block/blob/master/phpcs.xml) ruleset.
- `lint:css` runs stylelint over all the scss code in `assets/css`, using the rules in [.stylelintrc.json.](https://github.com/woocommerce/woocommerce-gutenberg-products-block/blob/master/.stylelintrc.json)
- `lint:js` runs eslint over all the JavaScript, using the rules in [.eslintrc.js.](https://github.com/woocommerce/woocommerce-gutenberg-products-block/blob/master/.eslintrc.js)
2019-08-12 11:48:58 +00:00
### Test
Run `$ npm run test` to run unit tests on the JavaScript.
The test scripts use [wp-scripts](https://github.com/WordPress/gutenberg/tree/master/packages/scripts) to run jest for component and unit testing.
- `test:update` updates the snapshot tests for components, used if you change a component that has tests attached.
- Use `test:watch` to keep watch of files and automatically re-run tests.
2019-08-12 11:48:58 +00:00
### Create an installable zip package
Run `$ npm run package-plugin` to trigger install and build, and then create a zip file which you can use to install WooCommerce Blocks in WordPress admin.
## Releasing new versions of blocks
2019-08-12 11:48:58 +00:00
These instructions cover new releases of the blocks plugin for those with commit access.
2019-08-12 11:48:58 +00:00
**Before any release** ensure you update:
- The `readme.txt` file supported versions, changelog and list of blocks if the release includes new blocks.
> Note: version numbers will automatically be updated in files via the deploy script (see `bin/version-changes.sh`).
2019-08-12 11:48:58 +00:00
### Tagging new releases on GitHub
2019-08-12 11:48:58 +00:00
Tagging a new version on GitHub can be done by running the following script:
```shell
$ npm run deploy
```
This will trigger a build and then run the release script (found in `/bin/github-deploy.sh`). This tags a new version and creates the GitHub release from your current branch.
__Important:__ Before running the deploy script ensure you have committed all changes to GitHub and that you have the correct branch checked out that you wish to release.
If you want to add additional details or a binary file to the release after deployment, [you can edit the release here](https://github.com/woocommerce/woocommerce-gutenberg-products-block/releases).
2019-08-12 11:48:58 +00:00
### Pushing new releases to WordPress.org
If you have SVN commit access to the WordPress.org plugin repository you can run the following script to prepare a new version:
```shell
$ npm run release
```
This will ask for a tagged version number, check it out from GitHub, check out the SVN repository, and prepare all files. It will give you a command when it's finished to do the actual commit; you have a chance to test/check the files before pushing to WordPress.org.
__Important:__ Before running the release script ensure you have already pushed a new release to GitHub.
## Publishing `@woocommerce/block-library`
2019-08-12 11:48:58 +00:00
We publish the blocks to npm at [@woocommerce/block-library,](https://www.npmjs.com/package/@woocommerce/block-library).
2019-08-12 11:48:58 +00:00
To release a new version, perform the following steps:
- Run `npm pack` to prep a `.tgz` file.
- Optionally test the package by uploading this onto a test site.
- Run `npm publish --access public`, which will push the version up to npm.
