makeDependency.RdA utility function to help in development of internal Javascript code, this function processes the Javascript to minify it and report on errors and bad style.
makeDependency(name, src, script = NULL, package,
version = packageVersion(package),
minifile = paste0(basename(src), ".min.js"),
debugging = FALSE, ...)Arguments to pass to htmltools::htmlDependency.
Basename of minified file.
See details below.
This is a utility function used by RGL
to process its Javascript code used when displaying rglwidget values. It may be helpful in other packages to use
in their own installation.
If the js package version 1.2 or greater is installed,
the Javascript code will be minified and stored in the file named
by minifile in the src directory. Syntax errors
in the code will stop the process; unused variables will be
reported.
If debugging is TRUE, the locations of Javascript syntax
errors will be reported, along with hints about improvements,
and the original files will be used in the dependency object
that is created.
If debugging is FALSE (the default),
the minified file will be used in the dependency object,
hints won't be given, and syntax errors will lead to an
uninformative failure to minify.
An object that can be included in a list of dependencies passed to htmltools::attachDependencies.
