Environment variables

Variable	Description	Default
VUE_APP_OBSERVATION_PORTAL_API_URL	Observation portal API URL	http://127.0.0.1:8000
VUE_APP_ARCHIVE_API_URL	Archive API URL	http://127.0.0.1:8000
VUE_APP_SIMBAD_SERVICE_URL	Simbad service URL	http://127.0.0.1:8000
INTERNAL_OBSERVATION_PORTAL_API_URL	In-cluster observation portal API URL	http://127.0.0.1:8000

The app configuration is stored in public/config/urls.json. When running the project using the docker image, the configuration in this file is updated in the docker entrypoint with the values set in the environment variables. To disable this behavior, for example when instead setting the configuration via a ConfigMap when running the application in Kubernetes, set DISABLE_OVERWRITE_APP_CONFIG_IN_ENTRYPOINT=true.

The internal observation portal url is used in the nginx configuration. It is necessary to route requests correctly when both the frontend and backend hostnames are the same. The kubernetes in-cluster url should be used for this value.

Project setup

npm install

Using local ocs-component-lib

If you are also developing against local changes to the ocs-component-lib project, you will need to follow some extra steps to install and use those changes locally without problems. The best description of the local development problem I've found is here, but basically if you just install the local directory or npm link it, the library will have its own different copy of the vue-composition-api library it attempts to use, which will not be instantiated properly so it will fail to work right. You can get around this by following these specific steps to install the local copy of the ocs-component-lib:

In the ocs-component-lib root directory

1. npm install
2. npm run build
3. npm prune --production
4. npm pack (should generate a local ocs-component-lib-{version}.tgz file)

In this root directory:

1. npm uninstall ocs-component-lib
2. npm install path/to/ocs-component-lib-{version}.tgz

Local Development

If you are developing locally, you will probably need to set a few variables in your development Observation Portal Django local settings file to handle cross site requests. For example, if your frontend is running at http://127.0.0.1:8080, you would set the following:

CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_WHITELIST = [
    'http://127.0.0.1:8080'
]
CSRF_TRUSTED_ORIGINS = [
    '127.0.0.1:8080'
]

Then, to run a hot-reload server for developing on the frontend:

npm run serve

Compiles and minifies for production

npm run build

Run your unit tests

npm run test:unit

Run your end-to-end tests

npm run test:e2e

Lints and fixes files

npm run lint:fix

Checks for linting errors without fixing them

npm run lint:check
