Multi-Purpose and High-Performance Routing.

waysign

waysign is a multipurpose, high-performance router build on top of the path-tree library. A router associates filepath-like patterns with a piece of data for latter retrieval. Often that data is a function and the path to be matched against the pattern comes from a URL, but it can be anything, adapting to the need of the user.

Installation

You can install the release version of waysign with install.packages("waysign"). If you want the development version you can install from github using pak:

pak::pak("thomasp85/waysign")

Example

Adapted from the path-tree docs

router <- waysign::signpost()

router$add_path("/", 1)
router$add_path("/login", 2)
router$add_path("/signup", 3)
router$add_path("/settings", 4)
router$add_path("/settings/:page", 5)
router$add_path("/:user", 6)
router$add_path("/:user/:repo", 7)
router$add_path("/public/:any*", 8)
router$add_path("/:org/:repo/releases/download/:tag/:filename.:ext", 9)
router$add_path("/:org/:repo/tags/:day-:month-:year", 10)

router$add_path("/:org/:repo/:page", 12)
router$add_path("/:org/:repo/*", 13)
router$add_path("/api/+", 14)
