Meteor APP的入口点/文件/功能是什么?

本文介绍了Meteor APP的入口点/文件/功能是什么?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我最近正在研究流星，它绝对方便又强大.但是到目前为止，仍然不清楚Meteor APP的入口是什么，换句话说，哪个文件/功能将首先执行?

I am recently studying Meteor which is absolutely convenient and powerful. But so far it is still not clear what is the entry point of a Meteor APP, in other words, which file/function will be executed first?

一个简单的例子:

client/hello.jsx:

import React from 'react';

export const Welcome = ({name}) => (
    <div>
        Hello, {name}.
    </div>
);

client/routes.jsx:

import React from 'react';
import {mount} from 'react-mounter';
import {Layout, Welcome} from './hello.jsx';

FlowRouter.route("/", {
  action() {
    mount(Layout,
      {content: (<Welcome name="My Shining Name" />)}
     );
  }
});

然后我使用命令:

然后将启动一个网页！看起来很神奇:服务器在哪里运行?网页是如何生成的?最重要的是，哪一段代码将首先执行?

Then a webpage is launched! It looks pretty magic: where is the server running? how the webpage is generated? Most importantly, which piece of code will be executed first?

谢谢

推荐答案

Meteor捆绑了源客户端文件，并将其分发给客户端.在此过程中，JS可能会被转译，样式表可能会自动添加前缀.最后，客户端执行捆绑软件.

Meteor bundles source client files and ships the bundle to the client. JS may be transpiled, and style sheets may be auto-prefixed during the process. At the end, the client executes the bundle.

源客户端文件是指名为'client'的文件夹中的文件.这些源文件按此文档中所述的顺序执行，引用如下.

A source client file refers to a file in a folder named 'client'. Those source files are executed in an order described in this document, quoted as below.

HTML模板文件总是先加载
以main开头的文件.最后加载
接下来将加载任何lib/目录中的文件
具有更深路径的文件接下来将被加载
然后按照整个路径的字母顺序加载文件

HTML template files are always loaded before everything else
Files beginning with main. are loaded last
Files inside any lib/ directory are loaded next
Files with deeper paths are loaded next
Files are then loaded in alphabetical order of the entire path

鉴于此列表，对于文件结构的初步了解至关重要.在这种理解下，例如，Meteor应用程序应该将哪个文件转到何处(客户端/服务器)，以及急切加载哪些文件，这对于决定如何构建应用程序至关重要.

Given the list, it's critical to build yourself some preliminary knowledge about the file structure of a Meteor application in that understanding, say, which file goes to where (client/serer) and which files are eagerly loaded is crucial to deciding how to structure an application.

回到您的应用程序.所显示的网页实质上是包含另一个React组件Welcome的React组件Layout.它们通过react-mounter安装到HTML模板中的DOM节点上，我相信在您的示例应用程序中是一个名为"client/index.html"或"client/hello.html"的文件.前述节点通常是具有指定id属性的div，或者是react-mount在运行时创建的DOM节点.

Getting back to your application. The webpage you are presented is essentially the React component Layout containing another React component Welcome. They are mounted by react-mounter onto a DOM node in a HTML template, which I believe in your example application is a file named 'client/index.html' or 'client/hello.html'. The aforementioned node is usually a div with a specified id attribute, or a DOM node created by react-mount at run time.

说到服务器端，Meteor运行一个增值的HTTP Web服务器，以便在启动Meteor应用程序时使用 Meteor API 来编程所需的功能.

Speaking of the server side, Meteor runs a value-added HTTP web server for when you start a Meteor application, and you program the features you like to have with Meteor APIs.

我希望以上信息能帮助您继续使用Meteor构建应用程序.享受吧！

I hope the information above help you proceed with building applications with Meteor. Enjoy!
