\title{Generate the Data URI for a file}
\usage{
base64_uri(x, type = mime::guess_type(x))
}
\arguments{
\item{x}{A file path.}

\item{type}{The MIME type of the file, e.g., \code{"image/png"} for a PNG
image file.}
}
\value{
A string of the form \verb{data:<media type>;base64,<data>}.
}
\description{
Encode the file in the base64 encoding, and add the media type. The data URI
can be used to embed data in HTML documents, e.g., in the \code{src}
attribute of the \verb{<img />} tag.
}
\note{
By default, this function requires the \pkg{mime} package to determine
  the MIME type of the file.
