requirejs项目中第一个define（）和require（）函数的格式是什么

Question

Question#1: After requirejs configuration, what will be the format of first require() call to load my main.js

App.js

requirejs.config({
    baseUrl: 'lib',
    paths: {
        app: '../app'
    }
});
require(['app/main'], function(m){
    console.log('loading m...');
});

Question#2: And what will be format of first define() function in main.js file.

Main.js

define(function () {
    var messages = require('./messages');
    var print = require('print');
});

Answer 1

The only issue I see in the code you show is that your main.js should have its define call like this:

define(function (require) {
  var messages = require('./messages');
  var print = require('print');
});

If you pass a function as the first parameter to define , RequireJS will call it with the special modules require , exports and module but at a minimum you must declare the first parameter so that the calls you made inside your factory function are to the local require (passed to the function) rather than the global require . There are a number of issues if you call the global require . One of them is that relative module references like ./messages won't be resolved correctly.

The require call you have in your app.js looks fine.
