我根据此处的文档使用django-pipeline和browserify -
http://gregblogs.com/how-django-reactjs-and-browserify/
我在装载NPM / Bower包时非常正常 -
'build_js': {
'source_filenames': (
'js/bower_components/jquery/dist/jquery.js',
'bootstrap/js/bootstrap.js',
'js/bower_components/react/react-with-addons.js',
'js/bower_components/react/react-dom.js',
'datatables/js/jquery.dataTables.js',
'datatables/js/dataTables.bootstrap.js',
'js/node_modules/marked/marked.min.js',
'js/node_modules/react-router/umd/ReactRouter.js',
'js/child.js',
'js/parent.js',
'js/build.browserify.js',
),
'output_filename': 'js/build_js.js',
问题是我试图在build.browserify.js中引用child.js和parent.js
这是3个文件的内容 -
child.js
var Child = React.createClass({
render: function(){
return (
<div>
and this is the <b>{this.props.name}</b>.
</div>
)
}
});
parent.js
var Parent = React.createClass({
render: function(){
return (
<div>
<div> This is the parent. </div>
<Child name="child"/>
</div>
)
}
});
build.browserify.js
ReactDOM.render(
<Parent />,
document.getElementById('content')
);
我的浏览器实际上有3个错误 -
第4行 -
上的child.js和parent.js文件发生了以下情况Uncaught SyntaxError: Unexpected token <
然后我在第3行的build.browserify.browserified.js上得到了这个
Uncaught ReferenceError: Parent is not defined
这是该文件的内容 -
(function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return s(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s})({1:[function(require,module,exports){
ReactDOM.render(
React.createElement(Parent, null),
document.getElementById('content')
);
},{}]},{},[1]);
编辑 -
如果我将所有代码放在一个build.browserify.js文件中,就可以了 -
var Child = React.createClass({
render: function(){
return (
<div>
and this is the <b>{this.props.name}</b>.
</div>
)
}
});
var Parent = React.createClass({
render: function(){
return (
<div>
<div> This is the parent. </div>
<Child name="child"/>
</div>
)
}
});
ReactDOM.render(
<Parent />,
document.getElementById('app')
);
答案 0 :(得分:2)
@ taylorc93与此相符,但你错过了一个额外的步骤。
除了必须在要包含父模块的任何文件中执行require('./parent')
之外,还需要实际导出parent.js
文件的内容。因此,parent.js
应如下所示:
<强> child.js 强>
var React = require('react');
modules.export = React.createClass({
displayName: 'Child', // Always setting React component's displayName will make your error messages easier to understand
render: function(){
return (
<div>
and this is the <b>{this.props.name}</b>.
</div>
)
}
});
<强> parent.js 强>
var React = require('react');
var Child = require('./child');
modules.export = React.createClass({
displayName: 'Parent', // Always setting React component's displayName will make your error messages easier to understand
render: function(){
return (
<div>
<div> This is the parent. </div>
<Child name="child"/>
</div>
)
}
});
<强> build.browserify.js 强>
var ReactDOM = require('react-dom');
var Parent = require('./parent');
ReactDOM.render(
<Parent />,
document.getElementById('app')
);
此外,虽然不是必需的,但最好为Component文件指定大写名称,就像在Java中分类文件一样。大多数应用也会将根文件命名为app.js
或main.js
或类似的东西,而不是build.browserify.js
这有点模糊,因为从技术上讲,该文件与构建或使用Browserify无关
