Check whether an update is available for an extension package

Wraps the extension's exported ntrd_update_available() with caching, error handling, and result validation. Safe to call from Shiny reactive contexts; will never raise an error.

Usage

check_extension_update(package, force = FALSE, ttl = 3600)

Arguments

package

Character string giving the extension package name.

force

Logical. If TRUE, ignore any cached result and re-check. Default FALSE.

ttl

Numeric. Cache time-to-live in seconds. Cached results older than ttl are refreshed on the next call. Default 3600 (one hour).

Value

An update_result S7 object. If the extension does not opt in to updates, or if the check errors, returns the safe update_result() default.
