How can I use the grunt-express for express 4.12?

问题

I use the Express 4.12 to build my project and I want to use grunt-express to start my application. I have known that Express 4.12 start the application via node ./bin/www, so I write the Gruntfile.js like this:

express: {
  dev: {
    options: {
      port: 3000,
      bases: path.resolve('bin/'),
      server: path.resolve('bin/www')
    }
  }
}

grunt.loadNpmTasks('grunt-express')
grunt.registerTask('default', ['express', 'express-keepalive']);

Unfortunately, when I run grunt, it reports an error:

Fatal error: Server should provide a function called "listen" that acts as http.Server.listen

But I found that in the www file, there is a function "listen":

var server = http.createServer(app)
server.listen(port);

I am confused about this. Could you please teach me write the Gruntfile.js for the www file?

回答1:

The grunt-express server option expects to see an express app, which is not what bin/www is. If you look at bin/www, what is it requiring for an express app? Eg, it should be an app.js in your project root, or maybe it would be server/index.js.

Also, your bases probably shouldn't be bin, rather it should be pointing to a public static resources dir, eg /public or if you have a build step that generates minified stuff it might be /dist.

Try this (editing server and bases to match your project):

grunt.initConfig({
    express: {
        options: {
            port: 3000,
            hostname: 'localhost'
        },
        dev: {
            options: {
                server: path.resolve('./app.js'),
                bases: [path.resolve('./public')]
            }
        }
    }
});
