npm add <package-name>

上面的命令将把包添加到节点模块并更新包。json文件

我只是写了一个简单的脚本来收集./node_modules中的依赖项。它满足了我目前的要求。这可能会对其他人有所帮助，我贴在这里。

var fs = require("fs");

function main() {
  fs.readdir("./node_modules", function (err, dirs) {
    if (err) {
      console.log(err);
      return;
    }
    dirs.forEach(function(dir){
      if (dir.indexOf(".") !== 0) {
        var packageJsonFile = "./node_modules/" + dir + "/package.json";
        if (fs.existsSync(packageJsonFile)) {
          fs.readFile(packageJsonFile, function (err, data) {
            if (err) {
              console.log(err);
            }
            else {
              var json = JSON.parse(data);
              console.log('"'+json.name+'": "' + json.version + '",');
            }
          });
        }
      }
    });

  });
}

main();

在我的例子中，上面的脚本输出:

"colors": "0.6.0-1",
"commander": "1.0.5",
"htmlparser": "1.7.6",
"optimist": "0.3.5",
"progress": "0.1.0",
"request": "2.11.4",
"soupselect": "0.2.0",   // Remember: remove the comma character in the last line.

现在，你可以复制和粘贴它们。玩得开心!

简单的回答:将已安装的npm模块添加到包中。Json不存在，使用

npm init -y

然后你就可以做了

npm i <module-name>

它会将该模块添加到package。json中

1. 选择

如果你是git和GitHub用户:

生成包比NPM init更简单。

else

或者你不喜欢包装。Json模板，生成包或NPM init生成:

你可以通过脚手架应用生成自己的模板，如generate, sails或yeoman。

2. 相关性

这个答案与2018年3月有关。在未来，来自这个答案的数据可能会过时。

这个答案的作者个人在2018年3月使用了generate-package。

3.限制

你需要使用git和GitHub来使用生成包。

4. 示范

例如，我创建了一个空白文件夹sasha-npm-init-vs-generate-package。

4.1. generate-package

命令:

D:\SashaDemoRepositories\sasha-npm-init-vs-generate-package>gen package
[16:58:52] starting generate
[16:59:01] √ running tasks: [ 'package' ]
[16:59:04] starting package

    "init",
    "npm",
    "package",
    "sasha",
    "vs"
  ]
}

4.2. npm init

D:\SashaDemoRepositories\sasha-npm-init-vs-generate-package>npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help json` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg>` afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.

我认为，这个generate-package更简单，这个npm init。

5. 定制

创建你自己的包。Json模板，见生成和yeoman的例子。

包。NPM使用Json文件来了解你的node.js项目。

使用npm init生成包。Json文件!

它与npm捆绑在一起。在这里阅读它的文档:https://docs.npmjs.com/cli/init

此外，您可以使用一个官方工具以编程方式生成该文件:https://github.com/npm/init-package-json

NPM热

创建包。Json文件，然后使用

Ls node_modules/ | xargs NPM install——save

填写node_modules文件夹中的模块。

Edit: @paldepind指出第二个命令是多余的，因为npm init现在会自动添加你在node_modules/文件夹中的内容。我不知道是不是一直都是这样，但至少现在，它不需要第二个命令就能工作。
