To work on this

The only prerequisite is Vagrant. If you don't know about it, please do some research and try it. After cloning the repository, run vagrant up dev in the console. Once it's done installing the virtual machine it'll automatically start compiling the app. After about 10 seconds, you can open the app at localhost:3000.

Project guidelines

• Please check out the project page for available tasks to work on.
• Before contributing also be sure to read our style guide
• Please clone the repository rather than forking, unless you're from outside the organization. It's easier for us to collaborate from a new branch on the same repository.
• After cloning the repository please run npm run install-hooks to add the git hooks to your local repository.
• If you see something that needs work, please create an issue. If the issue is on the frontend, please try to make it specific to one component.
• To work on an issue, create a new branch with a descriptive title.
• Please wait for at least two positive reviews before merging a PR into the master branch

Unit & end-to-end tests

There are two ways for running the tests. The first listed works from the host machine, and the second works after vagrant ssh dev and cd /vagrant:

npm run v-test (from host) or ng test (from vagrant) - Unit tests Open localhost:9876 once this is done compiling

npm run v-e2e (from host) or ng e2e (from vagrant) - End-to-end tests Results will appear in the console

Enabling the Hub

On the production Vagrant there is an optional second Planet instance that can be run to test out "Hub" features.

To start the hub: npm run hub-on The hub will be available at localhost:3200

To stop the hub: npm run hub-off

To set the hub to automatically start on vagrant up, run the following: npm run hub-boot-on

To disable autostart run following: npm run hub-boot-off

Additional commands

Similarly, we have a few other npm commands that work from the host machine to run the ng commands from the Angular CLI

npm run v-serve = ng serve

npm run v-build = ng build

npm run v-lint = ng lint

npm run v-lint-fix = ng lint --fix This will fix any lint errors that TSLint can automatically fix

Also, the npm start command can include an additional LNG variable to serve from different language files. This must be run from within the vagrant (so after vagrant ssh dev and cd /vagrant) and runs in the format:

LNG=es npm start

This would serve the app from the Spanish language files.

Troubleshooting

I switched branches and now I'm missing a dependency...

The ideal solution would be to ssh into your vagrant and run npm install:

vagrant ssh dev
cd /vagrant
npm install

This doesn't always work. If you're having trouble or need to revert to the exact dependencies listed on the package.json, you need to remove all packages then install (after cd /vagrant above, run the commands):

sudo rm -rf node_modules/*
sudo npm install --unsafe-perm

The trailing /* will remove all files & sub-directories of node_modules. You won't be able to remove node_modules because of the link between the vagrant VM and your host.

Cannot create new members in development environment or database missing

Sometimes our custom setup for the _users database is overwritten by the default or new databases were added in other commits that have not been created in your local environment. If you are seeing errors with lack of authorization or missing databases, you can run the following command to run our database setup script again:

./v-couchdb-setup.sh -u <your admin username> -w <your admin password>

Cannot GET /

There are two things you can try for this. First is to reinstall the node packages with:

vagrant ssh dev
cd /vagrant
sudo rm -rf node_modules/*
rm package-lock.json
sudo npm install --unsafe-perm

The second is to rebuild the application. First you need to cancel the app in the screen with screen -x then CTRL-C. Then you can bring the app back up with one of the above commands or in another screen session with screen -dmS build bash -c 'cd /vagrant; ng serve'.
