ONOS GUI 2.0.0

This project is based on Angular 6 and ES6 (aka ES2015), as an alternative to the 1.0.0 GUI which was based off AngularJS 1.3.5

Building, testing and running lint are all handled by BUCK. See web/gui2/BUCK file.

To use this new GUI you simply have to start the GUI in a running ONOS at the onos> cli:

feature:install onos-gui2

and the gui will be accessible at http://localhost:8181/onos/ui2

As usual with ONOS if you want to run it in a different language set the ONOS_LOCALE environment variable to the locale you want before starting onos. e.g.

ONOS_LOCALE=fr_FR onos-buck run onos-local

Development

There are 2 ways to go about development -

  1. rebuild the code and rerun through BUCK (much like can be done with any ordinary ONOS app) (this is not recommended though since in this mode the browser side code is built in '--prod' mode and all debug symbols are stripped and debug statements are not logged and the code is uglified and minimized. It is useful for testing "prod" mode works though) OR
  2. use Angular 6 CLI (ng command) to rebuild on the fly (must faster for development)

For 1) if you change the code you can redeploy the application without restarting ONOS with (requires you to be in ~/onos directory):

onos-buck build //web/gui2:onos-web-gui2-oar --show-output|grep /app.oar | cut -d\  -f2 | xargs onos-app localhost reinstall!

For 2) it's well worth becoming familiar with Angular CLI. The project is created with Angular CLI v6 to simplify development of the browser side code.

This allows you to develop the Angular 6 TypeScript code independent of ONOS in a separate container. Since WebSockets have been implemented (Jun 18) there is a requirement to run ONOS in the background.

There is no need to install node, npm or ng again on your system, and indeed if they are already installed, it's best to use the versions of these that's used by BUCK. To do this add to the start of your PATH environment variable.

~/onos/buck-out/gen/web/gui2/node-bin-v8.11.1/node-binaries/bin

On Linux:

export PATH=~/onos/buck-out/gen/web/gui2/node-bin-v8.11.1/node-binaries/bin:$PATH

After this you should be able to run 'ng -v' and see:

Angular CLI: 6.0.0
Node: 8.11.1
OS: linux x64

To use Angular CLI for development on your system, you need to:

  1. Change directory in to onos/web/gui2 - this is where you will run the ng command from.
  2. Run npm install once from this folder to add dependencies
  3. Then run 'ng -v' from onos/web/gui2 and an additional version should be shown Angular: 6.0.0

Development server

Run ng serve --aot for a dev server (because we are using ES6, we must use AOT). Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Press Ctrl-Shift-I in Chrome and Firefox to bring up the developer tools and the browser console.

There are certain extra debugging can be turned on by adding the parameter 'debug' For example to turn extra logging for WebSockets add on ?debug=txrx

On the Apps view - icons will appear to be missing - this is because they use a relative path to source the image, and this path is not available in this 'ng serve' mode. The icons work fine in the mode where it's run inside ONOS.

Code scaffolding

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.

Build

The build is handled through the web/gui2/BUCK file. This downloads Node, NPM and Angular CLI It runs ng build --prod --extract-css and copies everything over in to WEB-INF/classes/dist

To run it manually in Angular CLI run ng build (and add on --prod --extract-css --watch as necessary to alter its behaviour)

Running unit tests

This is automatically done when using "onos-buck test" - see the web/gui2/BUCK file for more details.

To run it manually in Angular CLI run ng test --watch to execute the unit tests via Karma. Running it directly like this will test with both Firefox and Chrome. To use only one use the --browsers argument

Running checkstyle

This is automatically done when using "onos-buck test" - see the web/gui2/BUCK file for more details.

To run it manually in Angular CLI run ng lint to run codelyzer on your code, according to the rules in tslint.json

Running end-to-end tests

To run it manually in Angular CLI run ng e2e to execute the end-to-end tests via Protractor.

Generating documentation

This is automatically done when using "onos-buck onos build" - see the web/gui2/BUCK file for more details.

To run it manually in Angular CLI run npm run compodoc to generate documentation via Compodoc
