Node.js 使用npm程序包验证程序包名称

node.js npm

Node.js 使用npm程序包验证程序包名称,node.js,npm,Node.js,Npm,有没有办法使用npm包来验证包名 const npm = require('npm'); const isValid = npm.validatePackageName('foobar'); // true const isValid = npm.validatePackageName('-4! *'); // false 我看到一个userland包可以做到这一点，但npm包本身肯定可以做到这一点吗？是否有从该软件包导出的公用设施？有效名称 var validate = require("

有没有办法使用npm包来验证包名

const npm = require('npm');

const isValid = npm.validatePackageName('foobar'); // true
const isValid = npm.validatePackageName('-4! *'); // false

我看到一个userland包可以做到这一点，但npm包本身肯定可以做到这一点吗？是否有从该软件包导出的公用设施？

有效名称

var validate = require("validate-npm-package-name")

validate("some-package")
validate("example.com")
validate("under_score")
validate("123numeric")
validate("excited!")
validate("@npm/thingy")
validate("@jane/foo.js")

validate(" leading-space:and:weirdchars")

以上所有名称都有效，因此您将返回此对象：

{
  validForNewPackages: true,
  validForOldPackages: true
}

{
  validForNewPackages: false,
  validForOldPackages: false,
  errors: [
    'name cannot contain leading or trailing spaces',
    'name can only contain URL-friendly characters'
  ]
}

无效名称

var validate = require("validate-npm-package-name")

validate("some-package")
validate("example.com")
validate("under_score")
validate("123numeric")
validate("excited!")
validate("@npm/thingy")
validate("@jane/foo.js")

validate(" leading-space:and:weirdchars")

这从来都不是一个有效的包名，因此您会看到：

{
  validForNewPackages: true,
  validForOldPackages: true
}

{
  validForNewPackages: false,
  validForOldPackages: false,
  errors: [
    'name cannot contain leading or trailing spaces',
    'name can only contain URL-friendly characters'
  ]
}

命名规则：

以下是有效npm包名称应遵守的规则列表：

包名称长度应大于零
包名称中的所有字符必须为小写，即不使用大写或允许混合大小写名称
包名称可以由连字符组成
包名称不得包含任何非url安全字符（因为名称结束是URL的一部分）
程序包名称不应以
或
```
\uu
```
开头
包名称不应包含任何前导或尾随空格
包名称不应包含以下任何字符：
```
~）（“！*
```
包名称不能与node.js/io.js核心模块或保留/黑名单名称。例如，以下名称无效：
- ```
http
```
- ```
流
```
- ```
node\u模块
```
- ```
favicon.ico
```
包名称长度不能超过214

您的包名由

组成，这就是问题所在。

基于@Nikita Ivanov的，涵盖了更多无效案例。代码：

var validate=require（“验证npm包名”）；
函数printPackageName验证（packageName）{
console.log（packageName）；
日志（验证（packageName））；
console.log（）；
}
//有效的
printPackageNameValidationFor（“虚线连字符减号有效”）；
printPackageNameValidationFor（“example.com有效期”）；
printPackageNameValidationFor（“低于有效分数”）；
printPackageNameValidationFor（“示例-123-numbers-validation”）；
printPackageNameValidationFor（“123以有效数字开头”）；
printPackageNameValidationFor（“作用域名称的@scope/at符号有效”）；
//无效的
printPackageNameValidationFor（“slashes@using-非scopename的at符号使用无效“）；
printPackageNameValidationFor（“斜杠/非范围名称无效”）；
printPackageNameValidationFor（“管道无效”）；
printPackageNameValidationFor（“感叹！for！new！packages！invalid”）；
printPackageNameValidationFor（“空格无效”）；
printPackageNameValidationFor（“html%20实体无效”）；
printPackageNameValidationFor（“方括号]-无效”）；
printPackageNameValidationFor（“逗号，无效”）；
printPackageNameValidationFor（“冒号：无效”）；
printPackageNameValidationFor（“分号；无效”）；
printPackageNameValidationFor（“单报价无效”）；
printPackageNameValidationFor（“双引号”无效）；
printPackageNameValidationFor（“波浪号~无效”）；

答案中的软件包是npm自己的官方软件包，因此他们可能没有将其包含在npm软件包中。将来他们可能会，但现在不会。目前，他们只通过类似npm.commands.install（[，cb]）的代码支持命令；您说“兴奋！”是一个有效的名称。但是@nikhil sugandh说包名称不应包含以下任何字符：~）（“！*”。哪一个是正确的？有效名称是否可以包含“！”？
