Scaffolding

# scaffolding empty project
yarn create nx-plugin nxp --pluginName ddd
lerna init --independent
yarn config set workspaces-experimental true
# adding new plugin
nx g @nrwl/nx-plugin:plugin [pluginName]
# example:
nx g @nrwl/nx-plugin:plugin ddd -d
nx g @nrwl/nx-plugin:plugin begetter -d

# to add new builder to your plugin
nx g @nrwl/nx-plugin:builder my-builder --project=begetter --description='My builder description' -d
# to add new schematic to your plugin
nx g @nrwl/nx-plugin:schematic my-schematic --project=begetter --description='My schematic description'  -d
# if you want to add migrations later
nx g @nrwl/nx-plugin:migration --project=begetter --version=1.2.3 -d

When you change any schematics's schema.json, run the following command to generate schema.d.ts

yarn build:schema

E2E Testing

# this won't work because, generated tmp project is of type cli=nx, but my schematics need project of type cli=angular
# tmp project has `workspace.json` instead of `angular.json`
nx e2e ddd-e2e

with your own test project

# build this schematic
nx run ddd:build
# cd to your demo nx project
cd my-demo-nx-project
# link the library
npm link ../nxp/dist/libs/ddd
# run the schematic
nx g @xmlking/nxp-ddd:domain booking

Publishing

To publish your plugin follow these steps:

via standard npm

  1. Build your plugin with the command nx run ddd:build
  2. npm publish ./dist/libs/ddd and follow the prompts from npm.
  3. That's it!

via learn

  1. lerna version
  2. lerna publish from-package (this will run prepublish life cycle script first)

To add your plugin modify the community/approved-plugins.json file in the Nrwl/nx repo and create a pull request with yarn submit-plugin.
