Create package

To create package once, package runner is recommended

$ npx @xyz/create-package my-package

# or

$ yarn create @xyz/package my-package

If you want to create packages later, install and use this package as follows

$ npm install -g @xyz/create-package

# or

$ yarn global add @xyz/create-package

# and then use

$ create-package my-package

You will be asked some questions about package

@xyz/create-package
✨ Generating package in my-package
? Package name my-package
? Package description My cat's meow package
? Package type React Typescript (TSX)
? Full name of package author Edvinas Pranka
? Email of package author (public) [email protected]
? Select license ISC
? Choose the package manager Yarn
? Build to UMD module for browsers (CommonJS is default) ? No
? Build to ES Module ? Yes
? Use unit tests ? Yes
? Use automatic semantic releases ? Yes
? Use Travis ? Yes
? Use Flow ? Yes
? Repository URL https://github.com/xyzrepo/create-package

If automated semantic releases are selected, package generation will take longer and you will be prompted for semantic release options

When your package are generated your entry point is in ./src/ directory. If Use unit tests are selected, tests can be found in ./__tests__ directory

In your package root directory you can run following commands

To build package

  $ yarn build    // or npm run build

To watch changes and build

  $ yarn watch    // or npm run watch

To lint package

  $ yarn lint     // or npm run lint

If Use unit tests are selected, test package

  $ yarn test     // npm run test

Publish lock

When the package created, the package.json file has a private property set to true. It prevents accidentally publishing the package. Then you are ready to publish, just remove private property from the package.json file.

Silent mode

You can create a package without user interaction using the --silent option. Pass package values along with the command. See section CLI Help below

  $ create-package my-package --name my-package --description "My cat's meow package" --type js --author "Baker Shamlan" --email "[email protected]" --license ISC --travis

If you choose --semantic-release option in silent mode, you will have to setup it after the package has been created. Use semantic-release-cli in the root of the package

  $ npm -g install semantic-release-cli
  $ semantic-release-cli setup

After setup, you can uninstall the semantic-release-cli package
