sd_reactive

This function creates a reactive value similar to Shiny's reactive() function,
but also automatically stores the calculated value in the survey data.

Generate programmable surveys using markdown and R code chunks. Surveys
are composed of two files: a survey.qmd 'Quarto' file defining the
survey content (pages, questions, etc), and an app.R file defining a
'shiny' app with global settings (libraries, database configuration,
etc.) and server configuration options (e.g., conditional skipping /
display, etc.). Survey data collected from respondents is stored in a
'PostgreSQL' database. Features include controls for conditional skip
logic (skip to a page based on an answer to a question), conditional
display logic (display a question based on an answer to a question), a
customizable progress bar, and a wide variety of question types,
including multiple choice (single choice and multiple choices),
select, text, numeric, multiple choice buttons, text area, and dates.
Because the surveys render into a 'shiny' app, designers can also
leverage the reactive capabilities of 'shiny' to create dynamic and
interactive surveys.
