one text-file for all texts

[FalkoFuroro]

We should find a solution to collect all texts in a file and make them accessible from this file.

This would make text editing much easier, even when translation is needed, for example.

Hi Falko,

Please see the Fundamental branch for the related updated. These changes were made:

Libraries: i18next: https://www.i18next.com/ react-i18next: https://react.i18next.com/

• Installed react-i18next and i18next: npm install react-i18next i18next
• Created LocaleContext.js in client/src/services
  • Contains i18n initialization
  • The t translation function
• Created locales directory in src/locales, contains en.json for now
  • Contains key-value pairs for translation
  • All translations can be stored in the en.json file which is the default namespace for the translations as of now. The JSON object has a key called translationwhich should include the key-value pairs. A translation can be used by calling the t function with the argument as t('key'), or t('key.nested') for nested keys
• LocaleContext is added in App.js as the highest component
• Imported LocaleContext in VirtualLayer.js and ExperimentUILayer.js for passing down required functions to child components
• Created a place for constants src/services/constants
  • index.js for common constants, components.js for component IDs
