Run one or more forever scripts/actions (forked/based on grunt-forever)
npm install grunt-forever-multi~0.4.1
shell
npm install grunt-forever-multi --save-dev
`
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
`js
grunt.loadNpmTasks('grunt-forever-multi');
`
Forever Multi task
$3
Gruntfile.js
`js
foreverMulti: {
basic: {
file: 'test/run.js'
},
appServer: {
action: 'restart',
file: 'test/run.js',
options: ["-m '"+cfgJson.app.name+" port "+cfgJson.server.port+"'"]
},
testServer: {
// action: 'restart', //default is restart if no action specified
file: 'test/run.js',
options: ["config=test", "-m '"+cfgTestJson.app.name+" port "+cfgTestJson.server.port+"'"]
}
}
`
Command Line
- command line arguments (grunt.option)
- action to override the action (i.e. --action=start will run the forever start action even if the task config is set to restart or stop action)
`js
run all tasks in this multiTask with their defaults / standard config
grunt foreverMulti
force a forever restart irregardless of what the config action is
grunt foreverMulti --action=restart
run just one of the tasks
grunt foreverMulti:appServer
`

The options / keys for each task mimic forever-monitor/forever: https://github.com/nodejitsu/forever-monitor including file and action keys. The only supported options currently are:
- file The file/script to run (i.e. index.js or server.js)
- action What to run forever with - see: https://npmjs.org/package/forever. Only start, restart, stop are supported currently.
- options Command line arguments to pass to forever
Other options including, but not limited to, silent, uid, max, command, sourceDir, watch, logFile, outFile, errFile are NOT currently supported.
Why? (Use Cases)
- For Continuous Integration - to restart your server(s) after a git push/webhook to get the file changes.
- i.e.: Use grunt to: 1. build new files/assets with the new code, 2. restart forever to update the running server/processes with the new code, 3. wait/timeout (sometimes necessary to allow the server time to fully restart), 4. run automated tests on the new code
Development
See https://npmjs.org/doc/developers.html for notes on publishing npm modules in general.
- run grunt to ensure no issues
- bump version number in package.json
- update CHANGELOG.md (and potentially this README.md) file
- git commit changes
- npm publish
- push to github (to update there as well)
TODO
- async / forever issues intermittently.. sometimes forever.startDaemon is called but grunt finishes WITHOUT done() being called (from this.async()) - this causes the script to exit - sometimes before the forever process is started and it stops future execution of any other tasks in the multi-task.. I'm not sure what's going on here or how to fix..
- add support for more (all?) forever options - i.e. uid, command, watch`
