tend

CLI Tool to run a command when a file changes

tend

Quick and easy cli command to watch a directory for file changes and run a provided command when any files have been changed, removed or added.

npm install -g tend
Usage:
  tend
  tend <action>
  tend [--restart] [--start] [--ignoreHidden] [--filter <filter>] [<dir> <command>]
  tend (--help | --version)
 
Options:
  -h --help             Show this help text
  -v --version          Show tend version information
  -r --restart          If <command> is still running when there is a change, stop and re-run it
  -i --ignoreHidden     Ignore changes to files which start with "."
  -f --filter <filter>  Use <filter> regular expression to filter which files trigger the command
  -s --start            Run <command> as soon as tend executes
tend --restart --ignoreHidden ./ "node server.js"

Running tend with no cli arguments will try to load your .tendrc file and start from any configuration set in that

tend will try to load your .tendrc file and run the command provided in the section <action>. It will run the command once and will not watch for changes in directory.

Run tend with options for a single directory/command from cli rather than loading options from .tendrc.

Show help/version information about tend

tend can accept it's configuration from a .tendrc file rather than taking arguments from the command line. Using .tendrc also allows you to run multiple instances of tend at once.

.tendrc files are parsed using rc.

; global settings 
ignoreHidden=true
 
[js]
directory=./src
command=uglifyjs -o ./build/main.min.js ./src/*.js
 
[app]
directory=./app
command=node ./app/server.js
restart=true
start=true

The above config will run two instances of tend:

tend --ignoreHidden ./src "uglifyjs -o ./build/main.min.js ./src/*.js"
# AND
tend --ignoreHidden --restart ./app "node ./app/server.js"
  • ignoreHidden - ignore hidden folders
  • restart - restart command if a file changes while the previous is still running
  • start - start command when tend starts
  • directory - the directory to watch for changes
  • filter - regular expression filter for filenames which will trigger command
  • command - the command to run when a file has changed
