Package 'opencpu'

OpenCPU Application

Description

Manage installed OpenCPU applications. These applications can be started locally using ocpu_start_app or deployed online on ocpu.io.

Usage

install_apps(repo, ...)

remove_apps(repo)

installed_apps()

available_apps()

update_apps(...)

Arguments

repo	a github repository such as user/repo, see remotes::install_github.
...	additional options for install_github

Details

OpenCPU apps are simply R packages. For regular users, apps get installed in a user-specific app library which is persistent between R sessions. This is used for locally running or developing web applications.

When running these functions as opencpu user on an OpenCPU cloud server, apps will be installed in the global opencpu server app library; the same library as used by the OpenCPU Github webhook.

OpenCPU Single-User Server

Description

Starts the OpenCPU single-user server for developing and running apps locally. To deploy your apps on a cloud server or ocpu.io, simply push them to github and install the opencpu webhook. Some example apps are available from github::rwebapps/.

Usage

ocpu_start_server(
  port = 5656,
  root = "/ocpu",
  workers = 2,
  preload = NULL,
  on_startup = NULL,
  no_cache = FALSE
)

ocpu_start_app(app, update = TRUE, ...)

Arguments

port	port number
root	base of the URL where to host the OpenCPU API
workers	number of worker processes
preload	character vector of packages to preload in the workers. This speeds up requests to those packages.
on_startup	function to call once server has started (e.g. utils::browseURL)
no_cache	sets Cache-Control: no-cache for all responses to disable browser caching. Useful for development when files change frequently. You might still need to manually flush the browser cache for resources cached previously. Try pressing CTRL+R or go incognito if your browser is showing old content.
app	either the name of a locally installed package, or a github remote (see install_apps)
update	checks if the app is up-to-date (if possible) before running
...	extra parameters passed to ocpu_start_server
