Description

Include the various HTML JavaScript and CSS assets created for js4shiny.

Usage

html_dependency_js4shiny(
  redirectConsole = TRUE,
  jsonview = TRUE,
  stylize = "all",
  use_google_fonts = FALSE
)

html_dependency_redirectConsoleLog()

html_dependency_stylize(...)

Arguments

`redirectConsole`	Include JS and CSS assets to enable literate programming with JavaScript by redirecting `console.log()` to a chunk- specific output div.
`jsonview`	Include JS and CSS assets to enable tree view display of JSON objects for the knitr json engine.
`stylize`	One of "none", "all", "fonts", "variables", "table", "utility", "code", "pandoc-line-numbers" to include the CSS styles developed for js4shiny.
`use_google_fonts`	Should fonts hosted on Google Fonts be included? Default is `FALSE`, where only system fonts will be used.

Functions

html_dependency_redirectConsoleLog: Include just the console redirection dependencies.
html_dependency_stylize: Include the full or partial js4shiny CSS styles.

An HTML Document with Support for Literate JavaScript Programming

Description

An R Markdown format for literate JavaScript programming. With default settings, each JavaScript chunk is run in its own environment and any output written with console.log() is inserted in the HTML document as the code runs. In this setting, the JavaScript is rendered directly in the browser at view time.

A similar effect can be achieved by using the js_live = FALSE chunk option to instead run the JavaScript code using node at compile time. In this setting, the results printed by the node process are captured and stored in the document, resulting in a non-dynamic output that captures the results of the JavaScript runtime code.

In both of the above settings, each code chunk is run separately. You can use the js_redirect = FALSE knitr chunk option to disable the console.log() redirect and use the standard JavaScript engine included in the knitr package. Logged statements will still be available in the browser's devolper tools console, as this engine is equivalent to having entered the JavaScript code directly into the HTML source within a ⁠<script>⁠ tag.

Usage

html_document_js(
  ...,
  theme = NULL,
  css = NULL,
  toc = FALSE,
  toc_depth = 3,
  mathjax = NULL,
  use_fontawesome = FALSE,
  use_google_fonts = FALSE,
  highlight = "haddock",
  fig_width = 10,
  fig_height = 7,
  fig_retina = 2,
  keep_md = FALSE,
  dev = "png",
  pandoc_args = NULL,
  extra_dependencies = NULL
)
html_document_js(
  ...,
  theme = NULL,
  css = NULL,
  toc = FALSE,
  toc_depth = 3,
  mathjax = NULL,
  use_fontawesome = FALSE,
  use_google_fonts = FALSE,
  highlight = "haddock",
  fig_width = 10,
  fig_height = 7,
  fig_retina = 2,
  keep_md = FALSE,
  dev = "png",
  pandoc_args = NULL,
  extra_dependencies = NULL
)

Arguments

`...`	Additional function arguments to pass to the base R Markdown HTML output formatter `html_document_base`
`theme`	Ignored
`css`	One or more css files to include
`toc`	`TRUE` to include a table of contents in the output
`toc_depth`	Depth of headers to include in table of contents
`mathjax`	Include mathjax. The "default" option uses an https URL from a MathJax CDN. The "local" option uses a local version of MathJax (which is copied into the output directory). You can pass an alternate URL or pass `NULL` to exclude MathJax entirely.
`use_fontawesome`	Should FontAwesome be included? Default is `FALSE`.
`use_google_fonts`	Should fonts hosted on Google Fonts be included? Default is `FALSE`, where only system fonts will be used.
`highlight`	One of the pandoc highlight styles.
`fig_width`	Default width (in inches) for figures
`fig_height`	Default height (in inches) for figures
`fig_retina`	Scaling to perform for retina displays (defaults to 2, which currently works for all widely used retina displays). Set to `NULL` to prevent retina scaling. Note that this will always be `NULL` when `keep_md` is specified (this is because `fig_retina` relies on outputting HTML directly into the markdown document).
`keep_md`	Keep the markdown file generated by knitting.
`dev`	Graphics device to use for figure output (defaults to png)
`pandoc_args`	Additional command line options to pass to pandoc
`extra_dependencies`	Additional function arguments to pass to the base R Markdown HTML output formatter `html_document_base`

Lint and Fix JavaScript file with StandardJS

Description

This addin lints and fixes selected JavaScript code or the currently open file in RStudio. The addin can be helpful for linting JavaScript code embedded in R Markdown or Shiny apps, in addition to linting whole JavaScript files. The underlying functions are not exported from js4shiny. If you want to programmatically lint multiple files, it would be better to use npm scripts or another JavaScript task running system to lint your files.

Installing StandardJS

standardjs is a style guide, code linter, and beautifier in one. It is also a command line tool (standard) for automatically formatting JavaScript code in the JavaScript Standard Style. The command line tool will also alert users to common style and programmer errors.

Using standard and this addin requires that node, npm, and standard be installed on your system. To install node and npm, you need to install Node.js (they come together). Follow the instructions from Node.js to install these tools. Confirm that your installation was successful by running npm -v in a new terminal session. Once npm is available, install standard globally by running this command in the terminal.

npm install standard --global

Serve a Live Preview

Description

Opens a live preview of the files in a directory. The live preview server automatically renders R Markdown files when they are saved, and the preview is refreshed whenever R Markdown files or supporting files, such as .js, .css, .htm, .html, .sass, or .scss files, are updated. This functionality requires the servr package.

Usage

live_preview(
  path = getwd(),
  update_pattern = "[.](js|css|[Rr]?[Mm][Dd]|html?|s[ca]ss)$",
  ...,
  render_quietly = getOption("js4shiny.live_preview.quiet", TRUE),
  external = FALSE
)

live_preview_stop(which = NULL)
live_preview(
  path = getwd(),
  update_pattern = "[.](js|css|[Rr]?[Mm][Dd]|html?|s[ca]ss)$",
  ...,
  render_quietly = getOption("js4shiny.live_preview.quiet", TRUE),
  external = FALSE
)

live_preview_stop(which = NULL)

Arguments

`path`	The path for the directory or file to preview. If the path given is an R Markdown document or HTML document, the HTML version of that file will be opened directly, otherwise the directory containing the file will be served.
`update_pattern`	Update the live preview when files matching this pattern are updated. By default, updating files with the following extensions will update the preview: `.Rmd` (case insensitive), `.html`, `.htm`, `.js`, `.css`, `.sass`, `.scss`.
`...`	Arguments passed on to `servr::httw` `dir` The root directory to serve. `watch` a directory under which `httw()` is to watch for changes; if it is a relative path, it is relative to the `dir` argument `pattern` a regular expression passed to `list.files()` to determine the files to watch `all_files` whether to watch all files including the hidden files `handler` a function to be called every time any files are changed or added under the directory; its argument is a character vector of the filenames of the files modified or added
`render_quietly`	If `TRUE` (default), the output from `rmarkdown::render()` will not be shown. Set to `FALSE` for debugging. You can set the default value with a global option: `options(js4shiny.live_preview.quiet = FALSE)`
`external`	Should the live preview be opened in an external browser? The default is `FALSE` and the preivew is opened in the RStudio viewer pane (if launched inside RStudio).
`which`	A integer vector of the server IDs; by default, IDs of all existing servers in the current R session obtained from `daemon_list()`, i.e., all daemon servers will be stopped by default.

Value

Invisibly returns the servr::httw() object, so that you can manually stop the server with the ⁠$stop_server()⁠ method.

Functions

live_preview_stop: Stop the live preview background daemons. See servr::daemon_list() for more information.

RStudio Addins

There are three Live Preview addins provided by js4shiny. Live Preview and Live Preview (External) open a live preview of the directory of the currently open document, if possible at the current HTML document corresponding to the open document. The external preview addin automatically opens the preview in your web browser, otherwise the preview is opened in the RStudio Viewer pane.

To stop the live server, you can call servr::daemon_stop() or live_preview_stop(), which will stop all bakground servr daemons, or you can use the Live Preview Stop addin.

Examples

if (interactive()) {

tmp_dir <- tempfile("live-preview")
dir.create(tmp_dir)
tmp_rmd <- file.path(tmp_dir, "js4shiny-plain.Rmd")

# Create a new js4shiny plain HTML document. If interactive
# and in RStudio, this file will open and you can use the
# addins to launch the live preview
js4shiny_rmd("js", full_template = TRUE, path = tmp_rmd)

srvr <- live_preview(tmp_rmd)

# Stop all background servers with either of the following
# live_preview_stop()
# servr::daemon_stop()
#
# Or if you've saved the return value from live_preview()
# srvr$stop_server()
}

if (interactive()) {

tmp_dir <- tempfile("live-preview")
dir.create(tmp_dir)
tmp_rmd <- file.path(tmp_dir, "js4shiny-plain.Rmd")

# Create a new js4shiny plain HTML document. If interactive
# and in RStudio, this file will open and you can use the
# addins to launch the live preview
js4shiny_rmd("js", full_template = TRUE, path = tmp_rmd)

srvr <- live_preview(tmp_rmd)

# Stop all background servers with either of the following
# live_preview_stop()
# servr::daemon_stop()
#
# Or if you've saved the return value from live_preview()
# srvr$stop_server()
}

Search the Mozilla Developers Network

Description

Searches the MDN Web Docs for a search term. Includes an RStudio addin for quick and seamless searching: highlight a term in the source code and run the addin to search MDN. If no text is highlighted, the addin opens a Shiny gadget for you to enter your search term.

Usage

mdn_search(
  term,
  browse = TRUE,
  topics = c("js", "api", "css", "html", "svg"),
  locale = "en-US"
)

mdn_gadget(browse = TRUE, locale = NULL)
mdn_search(
  term,
  browse = TRUE,
  topics = c("js", "api", "css", "html", "svg"),
  locale = "en-US"
)

mdn_gadget(browse = TRUE, locale = NULL)

Arguments

`term`	Search term
`browse`	Should the search results be opened in a browser window? If not, the URL is returned instead.
`topics`	A selection of topics to search, choosing from `"js"`, `"api"`, `"css"`, `"html"`, `"svg"`, `"mobile"`, `"canvas"`, `"webdev"`, and `"standards"`.
`locale`	The locale string for the search query. Default is `"en-US"`, or set to `NULL` to search MDN without specifying a locale.

Value

The search URL

Functions

mdn_gadget: A Shiny gadget for searching the MDN docs.

Register js4shiny knitr components

Description

Register the js4shiny knitr JavaScript engine or the output hooks. Generally, you will not need to use these. Instead, see html_document_js() or html_setup() for methods that cover most use-cases.

Usage

register_knitr_output_hooks(set = TRUE, chunk_hook = NULL)

register_knitr_js_engine(set = TRUE)
register_knitr_output_hooks(set = TRUE, chunk_hook = NULL)

register_knitr_js_engine(set = TRUE)

Arguments

`set`	If `FALSE` the output hook or JS engine are returned rather than setting via knitr directly.
`chunk_hook`	Chunk hook to be applied after the js4shiny chunk hook is applied to the chunk output. If `NULL`, then the current chunk hook is used. Only applies when `set = TRUE`.

REPL for live JS, CSS, and HTML development

Description

Launches an interactive Shiny app for live editing of frontend JavaScript, CSS, and HTML/Markdown/R Markdown. The app allows users to write JS, CSS and HTML, preview the final product, observe the JavaScript console (specifically items printed to the console via console.log()), and download a zip file containing the source files.

Usage

repl_example(example = NULL)

repl(
  example = NULL,
  js_repl_only = FALSE,
  theme_app = NULL,
  theme_editor = "textmate",
  autocomplete = c("css", "html"),
  render_dir = NULL,
  options = list(),
  ...
)

repl_js(..., render_dir = NULL)
repl_example(example = NULL)

repl(
  example = NULL,
  js_repl_only = FALSE,
  theme_app = NULL,
  theme_editor = "textmate",
  autocomplete = c("css", "html"),
  render_dir = NULL,
  options = list(),
  ...
)

repl_js(..., render_dir = NULL)

Arguments

`example`	The short name of the exercise or example, e.g. `ride-share-fares`. Alternatively, the path to a folder containing examples or the path to an example file directly. `repl_example(example = NULL)` opens an interactive browser to select an example, otherwise `repl()` and `repl_js()` will open with blank editors.
`js_repl_only`	When `TRUE`, the app is simplified to contain only a JavaScript source editor and a console output. `repl_js()` is an alias to launch `repl()` with `js_repl_only = TRUE`.
`theme_app`	The theme of the app, using shinythemes. See `shinythemes::shinytheme()` for a list of valid themes.
`theme_editor`	The theme of the shinyAce source code editors. See `shinyAce::getAceThemes()` for a list of valid themes.
`autocomplete`	Ace Editor language modes for which autocomplete will be enabled. One or more of `"js"`, `"css"`, or `"html"`. By default autocomplete is enabled in all but the JavaScript mode. "Disabling" autocomplete here actually doesn't mean disabling all together. Autocomplete will still be available by pressing `Ctrl` + `space`.
`render_dir`	Where to render temporary files, defaults to `tempdir()`
`options`	Options passed to `shiny::runApp()`.
`...`	Arguments passed from `repl_js()` to `repl()` or from `repl()` to `shiny::shinyApp()`.

Value

A shiny app

Functions

repl_example: Launch a js4shiny exercise or example using the example slug, or the full filename. If none provided, repl_example() launches an interactive example browser.

Examples for js4shiny workshop

The app was developed for the js4shiny rstudio::conf workshop and can be used to load examples for practicing and learning JavaScript and web development concepts.

Install js4shiny snippets

Description

This function installs a set of R, HTML, JavaScript and CSS snippets that are helpful when developing Shiny apps and doing web development work in RStudio. By default, the snippets are installed where RStudio will find them. If you haven't previously installed snippets to RStudio, these snippets will mask some of the built-in snippets that ship with RStudio.

Usage

snippets_install(install_path = NULL, update = TRUE)
snippets_install(install_path = NULL, update = TRUE)

Arguments

`install_path`	Where should the snippets be installed? If `NULL`, the snippets will install to a default path based on the current version of RStudio.
`update`	Should existing snippets be updated in place if there are any conflicts? Default is yes (`TRUE`). Otherwise, new snippets are appended to the end of the existing file, ensuring that you can recover your previous snippets by editing the snippets file.

Updating Existing Snippets

If you already have snippets installed, you can you can have the installed snippets update the existing snippets in place with update = TRUE. Or you can append the new snippets to the existing snippets files with update = FALSE. This option is desirable if you want to make sure that no snippets are overwritten. The newer snippets will mask older snippets, but no data will be lost.

Examples

snip_tmp <- tempfile("snippets")
dir.create(snip_tmp)
snippets_install(snip_tmp)

snip_tmp <- tempfile("snippets")
dir.create(snip_tmp)
snippets_install(snip_tmp)
