Autonomous and decentralized voting application utilizing Golos blockchain!
To get you started you can simply clone the golosuy repository and install the dependencies:
You need git to clone the golosuy repository.
We also use a number of Node.js tools to initialize and test golosuy. You must have Node.js
and its package manager (npm) installed.
Clone the golosuy repository using git:
git clone https://github.com/esteemapp/golosuy.git
cd golosuy
We have two kinds of dependencies in this project: tools and Angular framework code. The tools help us manage and test the application.
- We get the tools we depend upon via
npm, the Node package manager. - We get the Angular code via
bower, a client-side code package manager. - In order to run the end-to-end tests, you will also need to have the Java Development Kit (JDK) installed on your machine. Check out the section on end-to-end testing for more info.
We have preconfigured npm to automatically run bower so we can simply do:
npm install
Behind the scenes this will also call bower install. After that, you should find out that you have
two new folders in your project.
node_modules- contains the npm packages for the tools we needdocs/bower_components- contains the Angular framework files
Note that the bower_components folder would normally be installed in the root folder but
golosuy changes this location through the .bowerrc file. Putting it in the docs folder
makes it easier to serve the files by a web server.
We have preconfigured the project with a simple development web server. The simplest way to start this server is:
npm start
Now browse to the app at localhost:8000/index.html.
There are two kinds of tests in the golosuy application: Unit tests and end-to-end tests.
The golosuy app comes preconfigured with unit tests. These are written in Jasmine,
which we run with the Karma test runner. We provide a Karma configuration file to run them.
- The configuration is found at
karma.conf.js. - The unit tests are found next to the code they are testing and have an
_test.jssuffix (e.g.polls_test.js).
The easiest way to run the unit tests is to use the supplied npm script:
npm test
This script will start the Karma test runner to execute the unit tests. Moreover, Karma will start watching the source and test files for changes and then re-run the tests whenever any of them changes. This is the recommended strategy; if your unit tests are being run every time you save a file then you receive instant feedback on any changes that break the expected code functionality.
You can also ask Karma to do a single run of the tests and then exit. This is useful if you want to check that a particular version of the code is operating as expected. The project contains a predefined script to do this:
npm run test-single-run
The golosuy app comes with end-to-end tests, again written in Jasmine. These tests
are run with the Protractor End-to-End test runner. It uses native events and has
special features for Angular applications.
- The configuration is found at
e2e-tests/protractor-conf.js. - The end-to-end tests are found in
e2e-tests/scenarios.js.
Protractor simulates interaction with our web app and verifies that the application responds correctly. Therefore, our web server needs to be serving up the application, so that Protractor can interact with it.
Before starting Protractor, open a separate terminal window and run:
npm start
In addition, since Protractor is built upon WebDriver, we need to ensure that it is installed and
up-to-date. The golosuy project is configured to do this automatically before running the
end-to-end tests, so you don't need to worry about it. If you want to manually update the WebDriver,
you can run:
npm run update-webdriver
Once you have ensured that the development web server hosting our application is up and running, you can run the end-to-end tests using the supplied npm script:
npm run protractor
This script will execute the end-to-end tests against the application being hosted on the development server.
Since the Angular framework library code and tools are acquired through package managers (npm and bower) you can use these tools to easily update the dependencies. Simply run the preconfigured script:
npm run update-deps
This will call npm update and bower update, which in turn will find and install the latest
versions that match the version ranges specified in the package.json and bower.json files
respectively.
While Angular is client-side-only technology and it is possible to create Angular web apps that
do not require a backend server at all, we recommend serving the project files using a local
web server during development to avoid issues with security restrictions (sandbox) in browsers. The
sandbox implementation varies between browsers, but quite often prevents things like cookies, XHR,
etc to function properly when an HTML page is opened via the file:// scheme instead of http://.
The golosuy project comes preconfigured with a local development web server. It is a Node.js
tool called http-server. You can start this web server with npm start, but you may
choose to install the tool globally:
sudo npm install -g http-server
Then you can start your own development web server to serve static files from a folder by running:
http-server -a localhost -p 8000
Alternatively, you can choose to configure your own web server, such as Apache or Nginx. Just
configure your server to serve the files under the docs/ directory.
All you need in production are the files under the docs/ directory.
Everything else should be omitted.
Travis CI is a continuous integration service, which can monitor GitHub for new commits to
your repository and execute scripts such as building the app or running tests. The golosuy
project contains a Travis configuration file, .travis.yml, which will cause Travis to run your
tests when you push to GitHub.
You will need to enable the integration between Travis and GitHub. See the Travis website for instructions on how to do this.
