推荐答案

从根本上说，package.json 是应用程序的元文件.它列出了应用程序的所有配置.

Fundamentally, package.json is a meta file for your application. It lists all the configuration of your application.

只要您在本地运行所有代码并且不需要任何部署即可.

Nothing as far as you're running all your code locally and have no requirement for deployment whatsoever.

让我们设置一个场景让您更好地理解这一点.想象一下，您使用 node 编写了一个出色的应用程序.现在你周围的所有小鸡都想和它一起玩.太棒了！现在您想将其提供给他们，并且在开发过程中您npm install做了很多事情，以至于您的项目大小超过了 4TB.

Let's setup a scene for you to understand this better. Imagine that you wrote a brilliant application using node. Now all the chicks in your surrounding want it to play with. It is so fantastic! Now you want to give it to them and during the development process you npm installed so many things that your project grows beyond 4TB size.

没有可用的数据存储设备来处理庞大的代码库.

There is no data storage device available to shit that huge code base.

然后你梦寐以求的女孩说我想要，我现在就想要.因此，您开始寻找节点应用程序的应用程序部署流程.

Then the girl of your dream said I want it and I want it now. So you begin searching for app deployment process for node applications.

在那里你偶然发现了一个叫做 package.json 的神奇东西.

That is where you stumble upon a magical thing called package.json.

因此，您要做的是在 dependencies 属性下列出所有 npm install ed 模块.然后删除 node_modules 文件夹，添加 package.json 并在 github 中提交整个该死的东西.甚至 .zip 文件也是 10MB

So what you do is you list all your npm installed modules under dependencies property. Then you delete node_modulesfolder, add package.json and commit the entire damn thing in github. Even the .zip file is of 10MB

然后她得到了密码.在 npm install && 中输入npm start(这将安装 package.json` 中的所有依赖项并启动您的应用程序)

Then she gets the code. Types in npm install && npm start (which will install all the dependencies from the package.json` and start your application)

但是，如果您有 package.json，则可以在此处指定所有依赖项.

If you have package.json however, that is where you specify all your dependencies.

使用 npm install

示例.

npm install express --save

package.json 最初是如何创建的?是自动创建的吗?

How is package.json created in the first place? Is it created automatically?

您可以手动创建一个文本文件并将其保存为 package.json

You can manually create a text file and save it as package.json

或

更复杂的方法是使用命令

A more sophisticated way is to use the command

npm 初始化

我想知道为什么我没有 package.json

I am wondering why I do not have package.json

我也是！:)

您很可能正在学习一个不强调项目初始配置的教程，或者这些教程的作者假定读者已经掌握了所有基础知识.

You're most probably following a tutorial that doesn't emphasize on initial configuration of the project OR the author of those tutorials presume that the reader has all the fundamentals down to begin with.
