Voting module server logic

Handles the server-side logic for the mutation voting workflow. This includes:

• Reactively loading mutation images and metadata

• Capturing user input (agreement, observation, comment)

• Writing votes to a tsv file and session data to a database

• Advancing to the next voting item based on user interaction or trigger source

Usage

votingServer(
  id,
  cfg,
  login_trigger,
  db_pool,
  get_mutation_trigger_source,
  tab_trigger = NULL
)

Arguments

id

A string identifier for the module namespace.

cfg

App configuration

login_trigger

A reactive expression that indicates when a user has logged in.

db_pool

A database pool object (e.g. SQLite or PostgreSQL) for writing annotations.

get_mutation_trigger_source

A reactive expression that signals a new mutation should be loaded.

tab_trigger

Optional reactive that triggers when the voting tab is selected.

Value

None. Side effect only: registers reactive observers and UI updates.

Details

The module is triggered when the login_trigger reactive becomes active and optionally by get_mutation_trigger_source() to load new voting tasks.

Annotations are saved to the database connection provided in db_pool.
