This is a quick proof-of-concept single-page application to query a solr server containing TT-RSS data and display the results on a single page.
node.js bower
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.
We have preconfigured npm
to automatically run bower
so we can simply do:
npm install
Behind the scenes this will also call bower install
. You should find that you have two new
folders in your project.
node_modules
- contains the npm packages for the tools we needapp/bower_components
- contains the angular framework files
Note that the bower_components
folder would normally be installed in the root folder but
this app changes this location through the .bowerrc
file. Putting it in the app folder makes
it easier to serve the files by a webserver.
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 http://localhost:8000/app/index.html
.
app/ --> all of the source files for the application
app.css --> default stylesheet
components/ --> all app specific modules
query/ --> modules and providers related to the solr query
result/ ->> modules and providers related to solr results
app.js --> main application module
index.html --> app layout file (the main html template file of the app)
karma.conf.js --> config file for running unit tests with Karma
e2e-tests/ --> end-to-end tests
protractor-conf.js --> Protractor config file
scenarios.js --> end-to-end scenarios to be run by Protractor
###Testing is currently not implemented
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 sit and watch the source and test files for changes and then re-run the tests whenever any of them change. 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
This 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.
npm start
In addition, since Protractor is built upon WebDriver we need to install this. This project comes with a predefined script to do this:
npm run update-webdriver
This will download and install the latest version of the stand-alone WebDriver tool.
Once you have ensured that the development web server hosting our application is up and running and WebDriver is updated, 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.
You can update the tool dependencies by running:
npm update
This will find the latest versions that match the version ranges specified in the package.json
file.
You can update the Angular dependencies by running:
bower update
This will find the latest versions that match the version ranges specified in the bower.json
file.
While angular is client-side-only technology and it's possible to create angular webapps that
don't require a backend server at all, we recommend serving the project files using a local
webserver 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 file://
scheme instead of http://
.
This project comes preconfigured with a local development webserver. It is a node.js
tool called http-server. You can start this webserver 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 webserver, such as apache or nginx. Just
configure your server to serve the files under the app/
directory.
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. This
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 more instruction on how to do this.
