Grunt watch fails with message " Running "watch" task Waiting... Warning: Maximum call stack size exceeded "

Question

I have the next Gruntfile.js

 module.exports = function(grunt) { 'use strict'; // Load Grunt tasks declared in the package.json file require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks); // Configure Grunt grunt.initConfig({ // Grunt express - our webserver // https://github.com/blai/grunt-express express: { all: { options: { bases: 'xxxxxxxx', port: 9000, hostname: '0.0.0.0', livereload: true } } }, // grunt-watch will monitor the projects files // https://github.com/gruntjs/grunt-contrib-watch watch: { all: { files: ['**/*.html'], options: { livereload: true } } }, // grunt-open will open your browser at the project's URL // https://www.npmjs.org/package/grunt-open open: { all: { path: 'http://localhost:9000/index.html' } }, // grunt-open will install the bower components defined on the bower.json file // https://www.npmjs.com/package/grunt-bower-install-simple 'bower-install-simple': { options: { color: true, directory: 'assets/bower_components' }, 'prod': { options: { production: true } }, 'dev': { options: { production: false } } } }); // Creates the `server` task grunt.registerTask('server', [ 'express', 'open', 'watch' ]); };

 { "engines": { "node": ">= 0.10.0" }, "devDependencies": { "grunt-bower-install-simple": "~1.2.0", "grunt-contrib-watch": "~0.6.1", "grunt": "~0.4.5", "matchdep": "~1.0.0", "grunt-express": "~1.4.1", "grunt-open": "~0.2.3" } }

I try the solution in: Grunt watch error - Waiting...Fatal error: watch ENOSPC

but I still have this error:

Running "watch" task Waiting... Warning: Maximum call stack size exceeded

Did anyone knows what I am doing wrong?

Thanks!

From the doc of grunt-express , it seems setting livereload generates a watch task. I believe this task is conflicting with your own watch task.

Try removing your watch config and amending your server task to keep the server alive:

// Creates the `server` task
grunt.registerTask('server', [
    'express',
    'open',
    'express-keepalive'
    ]);
