Configurations

glue-config.js
The glue-config.js file is located at hub-ui/user-config/glue-config.js by default. It is the main project configuration file. The following table and example file shortly describes the configurable values.

custom_theme.scss
The custom-theme.scss file is located at hub-ui/user-config/custom-theme.scss by default. It contains Bootstrap 4 scss variables and overrides the default Bootstrap values. It must be used to change any general styling rules like spacing, sizes, colors etc. You can also add your own color variables to use them via Bootstrap classes or add other new variables.

i18n.json
The i18n.json file is located at hub-ui/user-config/i18n/i18n.json by default. It contains translations for all available languages for the vue-i18n module.

user-configs.js
The i18n.json file is located at hub-ui/config/user-configs.js by default. It contains the paths to the glue-config.js and i18n.json. By default that is the paths as described above.

UserImprint.vue and UserPrivacyPolicy
The UserImprint.vue and UserPrivacyPolicy.vue files are located at hub-ui/src/components/user/. They are more or less empty vue components where you should implement your Imprint/PrivacyPolicy pages in if you do not use external pages for those cases (configurable in glue-config.js).

index.js
The index.js file is located at hub-ui/config/index.js by default and is generated by the Vue-Webpack-Bundle. It contains several configurations for the development and production build process.

Build for Development

Open a terminal in the hub-ui directory and run:

$ npm run dev

This will start a local webserver on Port 8080 (unless you defined a different port in hub-ui/config/index.js).
Open a web browser and visit http://localhost:8080 to see the app.
Hot Module Replacement is supported. The page will update automatically whenever files are changed and saved.

Build for Production

Open a terminal in the hub-ui directory and run:

$ npm run build

This will optimize files for production and store the bundle in hub-ui/dist
Deploy the contents of hub-ui/dist on your webserver.

Run it via Docker

• Build the application for production

$ docker build -t edp/hub-ui .
$ docker run -i -p 8080:8080 edp/hub-ui

Runtime Configuration

We utilize a Vue plugin RuntimeConfiguration to configure a web application using environment variables without rebuilding it.

See runtime-config-template.js for all available runtime variables.

Usage

Normally, you would use process.env to consume environment specific configuration. This changes here. To consume environment variables in a Vue component, use this.$env as you would use process.env.

Example

this.$env.MATOMO_URL // Formerly process.env.MATOMO_URL

this.$env differs from process.env in a way that some properties that are set using environment variables are set here. That means that in a development environment, this.$env would be equivalent to process.env.

Creating new runtime variables

If you want to make configuration properties dynamic during runtime using environment variables, follow these steps:

1. In runtime-config-template.js, add your desired configuration variable as a property and enter its enivronment variable name as value. However, there are some restrictions you must follow:
   • Environment variable names in runtime-config-template.js must have the prefix $VUE_APP_.
   • Ensure that the property you want to replace during runtime is consistent in its name and structure.
2. Build and deploy the application.
3. Set your environment variable without the dollar sign $ at the beginning. For example, if your new entry in runtime-config-template.js is MATOMO_URL: '$VUE_APP_MATOMO_URL', make sure you set the environment variable VUE_APP_MATOMO_URL.
4. Your variable is now ready for consumption and can be changed during runtime by changing their associated environment variable.

Example

Let's suppose process.env looks like this (depending on how the project is set up):

{
  NODE_ENV: 'production',
  ROOT_API: 'https://www.europeandataportal.eu/metrics',
  ROOT_URL: 'https://www.europeandataportal.eu',
  MATOMO: {
      API_URL: 'https://www.ppe-aws.europeandataportal.eu/piwik/',
      ID: 89
  }
}

and you want to change ROOT_API, MATOMO.API_URL, and MATOMO.ID during runtime. Let's go through the steps outlined above:

1. runtime-config-template.js, would look like this:

export default {
  ROOT_API: '$VUE_APP_ROOT_API',
  MATOMO_URL: {
      API_URL: '$VUE_APP_MATOMO_API_URL',
      ID: '$VUE_APP_MATOMO_ID'
  }
}

2. Build and deploy.
3. Now set the environment variables. These are: VUE_APP_ROOT_API, VUE_APP_MATOMO_API_URL, and VUE_APP_MATOMO_ID.
