favicon.ico will be provided if it does not exist when serving files (thanks, @MMJansen, rstudio/pagedown#329).Added a function httr() to run R scripts and show output as HTML pages when serving a directory.
Added a new argument response to httd() to post-process the response.
auth argument to provide the authentication scheme and credentials. See the help page ?servr::server_config for more info.Fixed an issue with vign() that when an error occurs in the vignette, vign() wouldn’t stop rebuilding the vignette.
Fixed a character encoding issue #62 (thanks, @eternal-flame-AD).
vign() also watches for changes in js/css files now.
Stop using the encoding argument of knitr::knit() and rmarkdown::render().
Removed the experimental function notebook() from several years ago.
Added a function create_server() to create a server with a custom HTTP request handler and optionally a WebSocket handler.
Added a function redirect() to return a redirect response.
Added a new argument exclude to random_port() to exclude certain port numbers when generating a random available port.
The baseurl argument works for all server functions now, such as httd().
servr::random_port() on the host 127.0.0.1, the availability of the port is also tested on 0.0.0.0 by default. This is to avoid the situation where a port has been used on 0.0.0.0 but httpuv still thinks it is available on 127.0.0.1. If you want to skip this additional testing, you may set options(servr.test.0.0.0.0 = FALSE).options(servr.test.0.0.0.0 = TRUE), random_port() tests the availability of a port at the host address 0.0.0.0 when the requested host address is 127.0.0.1.Added a new argument hosturl to server_config().
Added a new argument filter to httw() to allow users to filter file paths on the watch list (thanks, @ARawles, #51).
server_config() will add a leading / to baseurl if it has not already been included.server_config() also returns the daemon value in the list.Fixed the malformed Accept-Ranges header (thanks, @JasonPunyon, #47).
servr::random_port() looks for an available port quietly via httpuv::startServer(quiet = TRUE). This requires httpuv >= v1.5.2.
open to servr::browse_last() so users can decide whether to reopen the lastly browsed page.R_SERVR_PORT is set, server_config() may issue a superfluous warning “createTcpServer: address already in use” due to an unnecessary call to random_port() (thanks, @itcarroll, #39).host in server_config() can be configured through the global option servr.host now, e.g., options(servr.host = '0.0.0.0').Added a verbose argument to server_config().
The interval argument of server_config() can be set via the global option servr.interval now. For example, options(servr.interval = 0.5).
Server functions such as httd() now return the config object created by server_config() instead of the server handle returned by httpuv::startServer(). The config object contains various information about the server and methods to start/stop the server.
Exported the function random_port() to return an available random TCP port.
daemon_list() returns server IDs instead of handles, so that it will work with httpuv >= v1.4.5.1 (rstudio/blogdown#365).
port argument of server_config() can be set via the environment variable R_SERVR_PORT. If the environment variable does not exist, the global option servr.port will be used if set, e.g., options(servr.port = 4322). See ?servr::server_config for details.Added a function browse_last() to reopen the last browsed page.
The daemon argument in server_config() now defaults to interactive(), i.e., servr starts a daemonized server that does not block your interactive R session by default.
httpuv::startDaemonizedServer() could crash the R session on Windowsadded a new argument watch to servr::httw()
exported the function server_config()
files/directories that contain multibyte characters in path names cannot be served correctly (thanks, Hao Peng)
on 404 (page not found), 404.html will be displayed if it exists under the root directory
improved the support for HTTP Range requests, e.g. servr can correctly serve MP4 videos now in major browsers including Safari
servr should decode requested paths before reading them (https://github.com/rstudio/blogdown/issues/85)
added an argument initpath to server_config() so you can open a specific path initially in the web browser
the daemon argument of server_config() takes the default value from the global option getOption('servr.daemon') now, e.g., you can set options(servr.daemon = TRUE) so that the daemonized server is always used
excluded ports considered unsafe by Chrome http://superuser.com/a/188070 when selecting a random port automatically
fixed a bug in 301 redirection when serving a directory without the trailing slash
you can disable websocket listening on an HTML page using a special HTML comment <!-- DISABLE-SERVR-WEBSOCKET --> when servr is serving and watching a directory, so that this page will not communicate with R (e.g. when it is updated, R will not send signals to refresh it) (thanks @hafen, #25)
a random TCP port will be used if the port 4321 is not available
added a function httw() to watch for changes under a directory and refresh an HTML page automatically (if it is being viewed in the browser) when any files are modified
servr accepts HTTP Range requests now (thanks, @rekado, #21)
servr did not work with RStudio Server (#20)
when running inside RStudio, the RStudio web browser will be used if available (requires RStudio >= 0.98.439)
added three server functions jekyll(), rmdv1(), and rmdv2() to serve Jekyll websites, R Markdown v1, and R Markdown v2 documents, respectively
added a server function vign() to serve R Markdown/HTML package vignettes
added a server function make() to serve a directory and update files automatically via Makefile (#2)
the URL pathname foo will be redirected to foo/ automatically if foo is a directory (#5)
in case of errors when serving dynamic documents, the server functions will double the delay to check for updates and wait for the next build until the error is cleared (like Gmail)
