opencpu (version 1.5.6)

opencpu: The httpuv based single-user OpenCPU server.

Description

This object controls the httpuv based OpenCPU server. This is the preferred method of running OpenCPU inside an R session. The server runs in a parallel process and does not interact with the current session.

Details

Note that this is a single user server; i.e. for local use only. Because R is single-threaded, the single-user server has no support for concurrent http requests (but httpuv does a nice job queueing them). Also there are no security restrictions being enforced, as is the case for the OpenCPU cloud server.

The OpenCPU server will automatically be started when the OpenCPU package is attached. By default, the server starts at a random port and the API will be available under the /ocpu path. For example: http://localhost:12345/ocpu/library/stats.

Once apps are working on the local OpenCPU server, they can easily be published using the OpenCPU cloud server. The cloud server does have support for concurrent requests, security policies and caching mechanisms to boost performance.
