pkgtrap: Install WebR packages to a local filesystem directory

pkgtrap (GL|NPM|Docs) is a small Node.js CLI application to make it easier to sync WebR WASM R packages to a local filesystem for CLI or web apps.

See the WebR CLI Book for details.

It is intended to be run as a CLI and is on NPM, so you can install it via:

$ npm install -g pkgtrap

You can also install the latest development version from GitLab:

$ npm install -g git+https://gitlab.com/hrbrmstr/pkgtrap

Usage

pkgtrap --help

Usage: pkgtrap [options] [packages...]

Makes a local copy of a list of WebR WASM packages and their dependencies.

Options:
  -V, --version           output the version number
  -o, --output-dir <dir>  path to output directory where WebR WASM packages
                          will be installed (will be created if it does not
                          exist) (default: "./pkgs")
  -h, --help              display help for command

pkgtrap defaults to using a local-to-current-working-directory ./pkgs directory but you can specify an alternate one via -o or --output-dir.

Here’s an example run that loads up {fs} and {glue}

pkgtrap fs glue
