Brief

Nodiaq was developed as a user interface for the XENONnT DAQ and XENONnT shift management. nodiaq_light is meant for experiments that run the same DAQ but are much simpler (e.g. only one detector instead of three, one reader/event builder instead of multiple, ...).

Installation

• Install nodejs and npm (ubuntu something like apt install nodejs npm)
• In source directory 'npm install' to install dependencies
• There are two options to configure the website:
  • Option 1: specify the following environment variables:
    • NODIAQ_HOST
    • NODIAQ_PORT
    • NODIAQ_MONGO_URI
    • NODIAQ_DAQ_DB
    • NODIAQ_GITHUB_ORG
    • NODIAQ_GITHUB_CLIENT_ID
    • NODIAQ_GITHUB_CLIENT_SECRET
    • NODIAQ_GITHUB_CALLBACK_URI
  • Option 2: specify the same options in config/config.js
• If you want to use environment variables but want to give them different names for some reason, change the names in the config/config.js file, accordingly.
• Start the server with node app.js.

Authentication System

The default user authentication works as follows:

• Users log in with their GitHub ID.
• If they are a public member of the specified config.github_org, they will be able to access the website.

You can shut off the user management completely by setting config.use_authentication = false;

If you want a user management system but can't use the one described above, help yourself! You will probably have to change the following files:

• config/passport.js: Check out passport.js
• routes/auth.js: This is where the logic with the organisation members is. You could also probably use a whitelist of allowed users or something along those lines.
• routes/common.js: Maybe you want to add something to the ensureAuthenticated function here and don't use passport at all.
