 # AWX UI
 
 ## Requirements
+- node.js 8.x LTS
+- npm 5.x LTS
+- bzip2, gcc-c++, git, make
 
-### Node / NPM
+## Development
+The API development server will need to be running. See [CONTRIBUTING.md](../../CONTRIBUTING.md).
 
-AWX currently requires the 6.x LTS version of Node and NPM.
+```shell
+# Build ui for the devel environment - reachable at https://localhost:8043
+make ui-devel
 
-macOS installer: [https://nodejs.org/dist/latest-v6.x/](https://nodejs.org/dist/latest-v6.x/)
+# Alternatively, start the ui development server. While running, the ui will be reachable
+# at https://localhost:3000 and updated automatically when code changes.
+make ui-docker
 
-RHEL / CentOS / Fedora:
-
-```
-$ curl --silent --location https://rpm.nodesource.com/setup_6.x | bash -
-$ yum install nodejs
-```
-
-### Other Dependencies
-
-On macOS, install the Command Line Tools:
-
-```
-$ xcode-select --install
-```
-
-RHEL / CentOS / Fedora:
-
-```
-$ yum install bzip2 gcc-c++ git make
-```
-
-## Usage
-
-### Starting the UI
-
-First, the AWX API will need to be running. See [CONTRIBUTING.md](../../CONTRIBUTING.md).
-
-When using Docker for Mac or native Docker on Linux:

+# When using docker machine, use this command to start the ui development server instead.
+DOCKER_MACHINE_NAME=default make ui-docker-machine
 ```
 
+## Development with an external server
 If you normally run awx on an external host/server (in this example, `awx.local`),
 you'll need to reconfigure the webpack proxy slightly for `make ui-docker` to
 work:

-
-### Adding new dependencies
-
-
-#### Add / update a bundled vendor dependency
-
-1. `npm install --prefix awx/ui --save some-frontend-package@1.2.3`
-2. Add `'some-package'` to `var vendorFiles` in `./grunt-tasks/webpack.js`
-3. `npm  --prefix awx/ui shrinkwrap` to freeze current dependency resolution
-
-#### Add / update a dependecy in the build/test pipeline
-
-1. `npm install --prefix awx/ui --save-dev some-toolchain-package@1.2.3`
-2. `npm  --prefix awx/ui shrinkwrap` to freeze current dependency resolution
-
-### Polyfills, shims, patches
-
-The Webpack pipeline will prefer module patterns in this order: CommonJS, AMD, UMD. For a comparison of supported patterns, refer to [https://webpack.github.io/docs/comparison.html](Webpack's docs).
-
-Some javascript libraries do not export their contents as a module, or depend on other third-party components. If the library maintainer does not wrap their lib in a factory that provides a CommonJS or AMD module, you will need to provide dependencies with a shim.
-
-1. Shim implicit dependencies using Webpack's [ProvidePlugin](https://github.com/webpack/webpack/blob/006d59500de0493c4096d5d4cecd64eb12db2b95/lib/ProvidePlugin.js). Example:
-
-```js
-// AWX source code depends on the lodash library being available as _
-_.uniq([1,2,3,1]) // will throw error undefined
-```
-
-```js
-// webpack.config.js
-plugins: [
-  new webpack.ProvidePlugin({
-      '_': 'lodash',
-  })
-]
-```
-
-```js
-// the following requirement is inserted by webpack at build time
-var _ = require('lodash');
-_.uniq([1,2,3,1])
-```
-
-2. Use [`imports-loader`](https://webpack.github.io/docs/shimming-modules.html#importing) to inject requirements into the namespace of vendor code at import time. Use [`exports-loader`](https://webpack.github.io/docs/shimming-modules.html#exporting) to conventionally export vendor code lacking a conventional export pattern.
-3. [Apply a functional patch](https://gist.github.com/leigh-johnson/070159d3fd780d6d8da6e13625234bb3). A webpack plugin is the correct choice for a functional patch if your patch needs to access events in a build's lifecycle. A webpack loader is preferable if you need to compile and export a custom pattern of library modules.
-4. [Submit patches to libraries without modular exports](https://github.com/leigh-johnson/ngToast/commit/fea95bb34d27687e414619b4f72c11735d909f93) - the internet will thank you
-
-Some javascript libraries might only get one module pattern right.
-
-### Environment configuration - used in development / test builds
-
-Build tasks are parameterized with environment variables.
-
-`package.json` contains default environment configuration. When `npm run myScriptName` is executed, these variables will be exported to your environment with the prefix `npm_package_config_`. For example, `my_variable` will be exported to `npm_package_config_my_variable`.
-
-Environment variables can accessed in a Javascript via `PROCESS.env`.
-
-``` json
-  "config": {
-    "django_port": "8013",
-    "websocket_port": "8080",
-    "django_host": "0.0.0.0"
-  }
-```
-
-Example usage in `npm run build-docker-machine`:
-
-```bash
-$ docker-machine ssh $DOCKER_MACHINE_NAME -f -N -L ${npm_package_config_websocket_port}:localhost:${npm_package_config_websocket_port}; ip=$(docker-machine ip $DOCKER_MACHINE_NAME); echo npm set awx:django_host ${ip}; $ grunt dev
-```
-
-Example usage in an `npm test` script target:
-
-```
-npm_package_config_websocket_port=mock_websocket_port npm_package_config_django_port=mock_api_port npm_package_config_django_host=mock_api_host npm run test:someMockIntegration
-```
-
-You'll usually want to pipe and set vars prior to running a script target:
-```
-$ npm set awx:websocket_host ${mock_host}; npm run script-name
-```
-
-### NPM Scripts
-
-Examples:
-```json
-  {
-    "scripts": {
-      "pretest": "echo I run immediately before 'npm test' executes",
-      "posttest": "echo I run immediately after 'npm test' exits",
-      "test": "karma start karma.conf.js"
-    }
-  }
-```
-
-`npm test` is an alias for `npm run test`. Refer to [script field docs](https://docs.npmjs.com/misc/scripts) for a list of other runtime events.
