plumber v1.1.0

Breaking changes

• Force json serialization of endpoint error responses instead of using endpoint serializer. (@meztez, #689)

• When plumbing a Plumber file and using a Plumber router modifier (#* @plumber), an error will be thrown if the original router is not returned. (#738)

• options_plumber() now requires that all options are named. If no option name is provided, an error with be thrown. (#746)

New features

• Added option plumber.trailingSlash. This option (which is disabled by default) allows routes to be redirected to route definitions with a trailing slash. For example, if a GET request is submitted to /test?a=1 with no /test route is defined, but a GET /test/ route definition does exist, then the original request will respond with a 307 to reattempt against GET /test/?a=1. This option will be enabled by default in a future release. This logic executed for before calling the 404 handler. (#746)

• Added an experimental option plumber.methodNotAllowed. This option (which is enabled by default) allows for a status of 405 to be returned if an invalid method is used when requesting a valid route. This logic executed for before calling the default 404 handler. (#746)

• Passing edit = TRUE to plumb_api() will open the API source file. (#699)

• OpenAPI Specification can be set using a file path. (@meztez #696)

• Guess OpenAPI response content type from serializer. (@meztez #684)

• Undeprecated Plumber$run(debug=, swaggerCallback=) and added the parameters for Plumber$run(docs=, quiet=) and pr_run(debug=, docs=, swaggerCallback=, quiet=). Now, all four parameters will not produce lingering effects on the Plumber router. (@jcheng5 #765)

  • Setting quiet = TRUE will suppress routine startup messages.
  • Setting debug = TRUE, will display information when an error occurs. See pr_set_debug().
  • Setting docs will update the visual documentation. See pr_set_docs().
  • Set swaggerCallback to a function which will be called with a url to the documentation, or NULL to do nothing. See pr_set_docs_callback().

• To update a PlumberEndpoint path after initialization, call the new PlumberEndpoint$setPath(path). This will update internal path matching meta data. (Active bindings were not used to avoid breaking changes.) (@blairj09 #770)

• PlumberStep (and PlumberEndpoint and PlumberFilter) received a new field $srcref and method $getFunc(). $srcref will contain the corresponding srcref information from original source file. $getFunc() will return the evaluated function. (#782)

• Allow for spaces in @apiTag and @tag when tag is surrounded by single or double quotes. (#685)

Bug fixes

• Ignore regular comments in block parsing. (@meztez #718)

• Block parsing comments, tags and responses ordering match plumber api ordering. (#722)

• Fixed bug where httpuv would return a status of 500 with body An exception occurred if no headers were set on the response object. (#745)

• Fixed bug where all pr_*() returned invisibly. Now all pr_*() methods will print the router if displayed in the console. (#740)

• When calling Plumber$handle() and defining a new PlumberEndpoint, ... will be checked for invalid names. (@meztez, #677)

• /__swagger__/ now always redirects to /__docs__/, even when Swagger isn't the selected interface. Use options(plumber.legacyRedirects = FALSE) to disable this behavior. (@blairj09 #694)

• Fixed available_apis() bug where all packages printed all available APIs. (@meztez #708)

• Fixed Plumber $routes resolution bugs. Routes are now returned in lexicographical order. (@meztez #702)

• Plumber will now display a circular reference if one is found while printing. (#738)

• Changed future::plan() from multiprocess to multisession in example API 14-future as "Strategy 'multiprocess' is deprecated in future (>= 1.20.0)". (#747)

• Setting options plumber.docs.callback to NULL will also set deprecated but supported option plumber.swagger.url. (#766)
