What would you like to do?
Automatically reload your node.js app on file change with Gulp (https://github.com/wearefractal/gulp).
// NOTE: I previously suggested doing this through Grunt, but had plenty of problems with
// my set up. Grunt did some weird things with scope, and I ended up using nodemon. This
// setup is now using Gulp. It works exactly how I expect it to and is WAY more concise.
var gulp = require('gulp'),
spawn = require('child_process').spawn,
node;
/**
* $ gulp server
* description: launch the server. If there's a server already running, kill it.
*/
gulp.task('server', function() {
if (node) node.kill()
node = spawn('node', ['index.js'], {stdio: 'inherit'})
node.on('close', function (code) {
if (code === 8) {
gulp.log('Error detected, waiting for changes...');
}
});
})
/**
* $ gulp
* description: start the development environment
*/
gulp.task('default', function() {
gulp.run('server')
gulp.watch(['./index.js', './lib/**/*.js'], function() {
gulp.run('server')
})
// Need to watch for sass changes too? Just add another watch call!
// no more messing around with grunt-concurrent or the like. Gulp is
// async by default.
})
// clean up if an error goes unhandled.
process.on('exit', function() {
if (node) node.kill()
})
