Interact with JavaScript built-in Functions

Description

activate_js is used to insert directly some JavaScript functions in your golem. By default bundle_ressources() load these function automatically for you.

Usage

activate_js()

invoke_js(fun, ..., session = shiny::getDefaultReactiveDomain())

Arguments

fun

JS function to be invoked.
...

JSON-like messages to be sent to the triggered JS function
session

The shiny session within which to call sendCustomMessage.

show

Show an element with the jQuery selector provided. Example: golem::invoke_js("show", "#id");.

hide

Hide an element with the jQuery selector provided. Example: golem::invoke_js("hide", "#id").

showid

Show an element with the id provided. Example: golem::invoke_js("showid", "id").

hideid

Hide an element with the id provided. Example: golem::invoke_js("hideid", "id").

showclass

Same as showid, but with class. Example: golem::invoke_js("showclass", "someClass").

hideclass

Same as hideid, but with class. Example: golem::invoke_js("hideclass", "someClass").

showhref

Same as showid, but with ⁠a[href*=⁠. Example: golem::invoke_js("showhref", "thinkr.fr").

hidehref

Same as hideid, but with ⁠a[href*=⁠. Example: golem::invoke_js("hidehref", "thinkr.fr").

clickon

Click on an element. The full jQuery selector has to be used. Example: golem::invoke_js("clickon", "#id").

disable

Add "disabled" to an element. The full jQuery selector has to be used. Example: golem::invoke_js("disable", ".someClass").

reable

Remove "disabled" from an element. The full jQuery selector has to be used. Example: golem::invoke_js("reable", ".someClass").

alert

Open an alert box with the message(s) provided. Example: golem::invoke_js("alert", "WELCOME TO MY APP");.

prompt

Open a prompt box with the message(s) provided. This function takes a list with message and id list(message = "", id = ""). The output of the prompt will be sent to input$id. Example: golem::invoke_js("prompt", list(message ="what's your name?", id = "name") ).

confirm

Open a confirm box with the message provided. This function takes a list with message and id list(message = "", id = ""). The output of the prompt will be sent to input$id. Example: golem::invoke_js("confirm", list(message ="Are you sure you want to do that?", id = "name") ).

Details

These JavaScript functions can be called from the server with invoke_js. invoke_js can also be used to launch any JS function created inside a Shiny JavaScript handler.

Value

Used for side-effects.

Golem Function Template

Description

Function templates can be used to extend the add_fct() creation mechanism with your own template, so that you can be even more productive when building your {shiny} app. Function template functions do not aim at being called as is by users, but to be passed as an argument to the add_fct() function.

Extra arguments, ignored by the default template.

Details

A template function can take the following arguments to be passed from add_fct():

  • name: the name of the function

  • path: the path to the file in R/

  • export: a TRUE/FALSE value

If you want your function to ignore these parameters, set ... as the last argument of your function, then these will be ignored. See the examples section of this help.

Usage

get_current_config(path = getwd())

Arguments

path

character string giving the path to start looking for the config; the usual value is the {golem}-package top-level directory but a user supplied config is now supported (see Details for how to use this feature).

Details

In most cases this function simply returns the path to the default golem-config file located under "inst/golem-config.yml". That config comes in yml-format, see the Engineering Production-Grade Shiny Apps for further details on its format and how to set options therein.

Advanced app developers may benefit from having an additional user config-file. This is achieved with setting the GOLEM_CONFIG_PATH env var.

  title = "this",
  content = "that",
  ...
  ) {
    with_golem_options(
      app = shinyApp(

Variants

  • use_skills() is the main entry point — pick the agent target via agent_specs ("claude", "agents", or "both").

  • use_agent_skills() and use_claude_skills() are convenience wrappers for use_skills(agent_specs = "agents") and use_skills(agent_specs = "claude").

  • use_skill() adds a single skill to an already-installed agent target, without touching CLAUDE.md / AGENTS.md.
