+# ngXosLib
+
+This is a collection of helpers to develop views as Angular SPA.
+
+## Tools
+
+This tools are designed to help you developing UI for XOS. As they born for this purpose if often necessary that a XOS instance is running on your sistem and responding at: `localhost:9999`. The `xos/configurations/frontend` is normally enough.
+
+### Apigen
+
+Usage: `npm run apigen`
+
+This tool will automatically generate an angular resource file for each endpoint available in Swagger.
+
+>You can generate api related documentation with: `npm run apidoc`. The output is locate in `api/docs`. You can have a list of available method also trough Swagger at `http://localhost:9999/docs/`
+
+### Vendors
+
+Xos comes with a preset of common libraries, as listed in `bower.json`:
+- angular
+- angular-route
+- angular-resource
+- angular-cookie
+- ng-lodash
+
+This libraries are server through Django, so they will not be included in your minified vendor file. To add a library and generate a new file (that will override the old one), you should:
+- enter `ngXosLib` folder
+- run `bower install [myPackage] --save`
+- rebuild the file with `gulp vendor`
+
+>_NOTE before adding libraries please discuss it to avoid this file to became huge_
+
+### Helpers
+
+XOS comes with an helper library that is automatically loaded in the Django template.
+
+To use it, add `xos.helpers` to your required modules:
+
+```
+angular.module('xos.myView', [
+  'xos.helpers'
+])
+```
+
+It will automatically ad a `token` to all your request, eventually you can take advantage of some other services:
+
+- **NoHyperlinks Interceptor**: will add a `?no_hyperlinks=1` to your request, to tell Django to return ids instead of links.
+- **XosApi** wrapper for `/xos` endpoints.
+- **XoslibApi** wrapper for `/xoslib` endpoints.
+- **HpcApi** wrapper for `/hpcapi` endpoints.
+
+>_NOTE: for the API related service, check documentation in [Apigen](#apigen) section._
+
+### Yo Xos
+
+We have created a [yeoman](http://yeoman.io/) generator to help you scaffolding views.
+
+>As it is in an early stage of development you should manually link it to your system, to do this enter `xos/core/xoslib/ngXosLib/generator-xos` and run `npm link`.
+
+#### To generate a new view
+
+From `xos/core/xoslib` run `yo xos`. This command will create a new folder with the provided name in: `xos/core/xoslib/ngXosViews` that contain your application.
+
+>If you left empty the view name it should be `xos/core/xoslib/ngXosViews/sampleView`
+
+#### Run a development server
+
+In your `view` folder and run `npm start`.
+
+_This will install required dependencies and start a local server with [BrowserSync](http://www.browsersync.io/)_
+
+#### Publish your view
+
+Once your view is done, from your view root folder, run: `npm run build`.
+
+This will build your application and copy files in the appropriate locations to be used by django.
+
+At this point you can enter: `http://localhost:9999/admin/core/dashboardview/add/` and add your custom view.
+
+>_NOTE url field should be `template:xosSampleView`_
+
+#### Install dependencies in your app
+
+To install a local dependency use bower with `--save`. Common modules are saved in `devDependencies` as they already loaded in the Django template.
+
+The `npm start` command is watching your dependencies and will automatically inject it in your `index.html`.
+
+#### Linting
+
+A styleguide is enforced trough [EsLint](http://eslint.org/) and is checked during the build process. We **highly** suggest to install the linter in your editor to have realtime hint.
+
+#### Test
+
+The generator set up a test environment with a default test.
+To run it execute: `npm test`
+
+## TODO
+
+- Use Angular $resource instead of $http
+- Use ngDoc instead of jsDoc
+- Define styleguide (both visual and js) and if needed define some UI components
