Quarto Preview — quarto_preview • quarto

Render and preview a Quarto document or website project.

Usage

quarto_preview(
  file = NULL,
  render = "auto",
  port = "auto",
  host = "127.0.0.1",
  browse = TRUE,
  watch = TRUE,
  navigate = TRUE,
  quiet = FALSE
)

quarto_preview_stop()

Arguments

file: The document or website project directory to preview (defaults to current working directory)
render: For website preview, the most recent execution results of computational documents are used to render the site (this is to optimize startup time). If you want to perform a full render prior to serving pass "all" or a vector of specific formats to render. Pass "default" to render the default format for the site. For document preview, the document is rendered prior to preview (pass FALSE to override this).
port: Port to listen on (defaults to 4848)
host: Hostname to bind to (defaults to 127.0.0.1)
browse: Open a browser to preview the content. Defaults to using the RStudio Viewer when running within RStudio.Pass a function (e.g. utils::browseURL to override this behavior).
watch: Watch for changes and automatically reload browser.
navigate: Automatically navigate the preview browser to the most recently rendered document.
quiet: Suppress warning and other messages, from R and also Quarto CLI (i.e --quiet is passed as command line)

Details

Automatically reloads the browser when input files are re-rendered or document resources (e.g. CSS) change.
