grunt-nodemon
Run nodemon as a grunt task for easy configuration and integration with the rest of your workflow
Getting Started
If you haven't used grunt before, be sure to check out the Getting Started guide, as it explains how to create a gruntfile as well as install and use grunt plugins. Once you're familiar with that process, install this plugin with this command:
npm install grunt-nodemon --save-dev
Then add this line to your project's Gruntfile.js gruntfile:
grunt.loadNpmTasks('grunt-nodemon');
Documentation
Minimal Usage
The minimal usage of grunt-nodemon runs with a script specified:
nodemon: {
dev: {
script: 'index.js'
}
}
Usage with all available options set
nodemon: {
dev: {
script: 'index.js',
options: {
args: ['dev'],
nodeArgs: ['--debug'],
callback: function (nodemon) {
nodemon.on('log', function (event) {
console.log(event.colour);
});
},
env: {
PORT: '8181'
},
cwd: __dirname,
ignore: ['node_modules/**'],
ext: 'js,coffee',
watch: ['server'],
delay: 1000,
legacyWatch: true
}
},
exec: {
options: {
exec: 'less'
}
}
}
Advanced Usage
A common use case is to run nodemon with other tasks concurrently. It is also common to open a browser tab when starting a server, and reload that tab when the server code changes. These workflows can be achieved with the following config, which uses a custom options.callback function, and grunt-concurrent to run nodemon, node-inspector, and watch in a single terminal tab:
concurrent: {
dev: {
tasks: ['nodemon', 'node-inspector', 'watch'],
options: {
logConcurrentOutput: true
}
}
},
nodemon: {
dev: {
script: 'index.js',
options: {
nodeArgs: ['--debug'],
env: {
PORT: '5455'
},
// omit this property if you aren't serving HTML files and
// don't want to open a browser tab on start
callback: function (nodemon) {
nodemon.on('log', function (event) {
console.log(event.colour);
});
// opens browser on initial server start
nodemon.on('config:update', function () {
// Delay before server listens on port
setTimeout(function() {
require('open')('http://localhost:5455');
}, 1000);
});
// refreshes browser when server reboots
nodemon.on('restart', function () {
// Delay before server listens on port
setTimeout(function() {
require('fs').writeFileSync('.rebooted', 'rebooted');
}, 1000);
});
}
}
}
},
watch: {
server: {
files: ['.rebooted'],
options: {
livereload: true
}
}
}
Note that using the callback config above assumes you have open installed and are injecting a LiveReload script into your HTML file(s). You can use grunt-inject to inject the LiveReload script.
Required property
script
Type: String
Script that nodemon runs and restarts when changes are detected.
Options
args
Type: Array of Strings
List of arguments to be passed to your script.
nodeArgs
Type: Array of Strings
List of arguments to be passed to node. The most common argument is --debug or --debug-brk to start a debugging server.
callback
Type: Function
Default:
function(nodemon) {
// By default the nodemon output is logged
nodemon.on('log', function(event) {
console.log(event.colour);
});
};
Callback which receives the nodemon object. This can be used to respond to changes in a running app, and then do cool things like LiveReload a web browser when the app restarts. See the nodemon docs for the full list of events you can tap into.
ignore
Type: Array of String globs Default: ['node_modules/**']
List of ignored files specified by a glob pattern relative to the watched folder. Here is an explanation of how to use the patterns to ignore files.
ext
Type: String Default: 'js'
String with comma separated file extensions to watch. By default, nodemon watches .js files.
watch
Type: Array of Strings Default: ['.']
List of folders to watch for changes. By default nodemon will traverse sub-directories, so there's no need in explicitly including sub-directories.
delay
Type: Number Default: 1000
Delay the restart of nodemon by a number of milliseconds when compiling a large amount of files so that the app doesn't needlessly restart after each file is changed.
legacyWatch
Type: Boolean Default: false
If you wish to force nodemon to start with the legacy watch method. See https://github.com/remy/nodemon/blob/master/faq.md#help-my-changes-arent-being-detected for more details.
cwd
Type: String
The current working directory to run your script from.
env
Type: Object
Hash of environment variables to pass to your script.
exec
Type: String
You can use nodemon to execute a command outside of node. Use this option to specify a command as a string with the argument being the script parameter above. You can read more on exec here.
Changelog
0.3.0 - Updated to nodemon 1.2.0.
0.2.1 - Updated README on npmjs.org with correct options.
0.2.0 - Updated to nodemon 1.0, added new callback option.
Breaking changes:
options.fileis nowscriptand is a required property. Some properties were changed to match nodemon:ignoredFiles->ignore,watchedFolders->watch,delayTime->delay,watchedExtensions->ext(now a string) to match nodemon.
0.1.2 - nodemon can now be listed as a dependency in the package.json and grunt-nodemon will resolve the nodemon.js file's location correctly.
0.1.1 - Added legacyWatch option thanks to @jonursenbach.
0.1.0 - Removed debug and debugBrk options as they are encapsulated by the nodeArgs option.
Breaking changes:
- Configs with the
debugordebugBrkoptions will no longer work as expected. They simply need to be added tonodeArgs.
0.0.10 - Added nodeArgs option thanks to @eugeneiiim.
0.0.9 - Fixed bug when using cwd with ignoredFiles.
0.0.8 - Added error logging for incorrectly installed nodemon.
0.0.7 - Added debugBreak option thanks to @bchu.
0.0.6 - Added env option.
0.0.5 - Added cwd option.
0.0.4 - Added nodemon as a proper dependency.
0.0.3 - Uses local version of nodemon for convenience and versioning.
0.0.2 - Removes .nodemonignore if it was previously generated and then the ignoredFiles option is removed.
0.0.1 - Added warning if nodemon isn't installed as a global module.
0.0.0 - Initial release
