Set global base URL for webR links — set_webr_base

Overrides the base URL used when building webR REPL links, for instance to point at a self-hosted or pinned webR deployment. The value is stored in the livelink.base_url option and applies to webR links only; Shinylive links are unaffected. Once set, a custom base URL takes precedence over the version argument passed to the link builders.

Usage

set_webr_base_url(base_url = NULL)

Arguments

base_url: Custom base URL to use for all webR links

Value

Invisibly returns the base_url value (or NULL if resetting to default).

Examples

# Remember the current setting so it can be restored afterwards
old <- getOption("livelink.base_url")

# Set custom base URL
set_webr_base_url("https://my-custom-webr.com/")
#> webR base URL set to: <https://my-custom-webr.com/>

# Reset to default (removes custom setting)
set_webr_base_url(NULL)
#> webR base URL reset to default

# Restore the previous setting
set_webr_base_url(old)
#> webR base URL reset to default
