cookies (version 0.2.3)

set_cookie: Create or update a cookie

Description

Instruct the user's browser to create a cookie via JavaScript.

Usage

set_cookie(
  cookie_name,
  cookie_value,
  expiration = 90,
  secure_only = NULL,
  domain = NULL,
  path = NULL,
  same_site = NULL,
  session = shiny::getDefaultReactiveDomain()
)

Value

A call to session$sendCustomMessage() which sets the targeted cookie.

Arguments

cookie_name

The name of the cookie. Can contain any US-ASCII characters except for: the control character, space, a tab, or separator characters like ( ) < > @ , ; : \ " / [ ] ? = { }.

cookie_value

The contents of the cookie as a single character value.

expiration

Days after which the cookie should expire. To remove an HttpOnly cookie, send a negative value for this attribute.

secure_only

Logical indicating whether the cookie should only be accessible via secure (https:) requests (except on localhost).

domain

The host to which the cookie will be sent (including subdomains). If this is NULL (default) the cookie will only be sent to the host of the page where this cookie was set (not including subdomains).

path

The path that must exist in the requested URL for the browser to send this cookie. Includes subdirectories.

same_site

One of "strict", "lax" (default), or "none", indicating when the cookie should be sent. When same_site = "none", secure_only must be TRUE.

session

Shiny session in which the cookies can be found (the default should probably always be used).

Examples

server <- function(input, output, server) {
  shiny::observeEvent(
    input$button_that_sets_cookie,
    set_cookie(
      "my_cookie",
      "the value of this cookie"
    )
  )
}
