stringifyWithWhitelist

• This npm package provides a method called stringifyWithWhitelist that allows you to convert a JavaScript object into a string, but only includes key paths in a whitelist. This method marks circular references with "[Circular]" when dealing with objects containing circular references.

Installation

• Install this package using npm:

npm install stringify-with-whitelist

Usage

• First, import the stringifyWithWhitelist and stringifyWithBlacklist method:

const { stringifyWithWhitelist,stringifyWithBlacklist } = require('stringify-with-whitelist');

Then, you can pass any JavaScript object to the stringifyWithWhitelist method and provide an array containing whitelist key paths so that only these paths are included when converting to a string.

Copy code
const obj = {
  a: {
    b: {
      c: 1,
      d: 2
    },
    e: 3
  },
  f: [4, 5, 6]
};

const whitelist = ['a.b.c', 'a.e', 'f.*'];

const result = stringifyWithWhitelist(obj, whitelist);
console.log(result);

Output

css
{
  a: {
    b: {
      c: 1
    },
    e: 3
  },
  f: [
    4,
    5,
    6
  ]
}

API

• stringifyWithWhitelist(obj, whitelist)
  • obj (Object): The JavaScript object to be converted into a string.
  • whitelist (Array): An array of strings containing the key paths to be included in the output. Use an asterisk () to represent array elements. Examples: 'a.b.c', 'f.'. Return value: A string representing the JavaScript object filtered through the whitelist.

Note: This method marks circular references with "[Circular]" when dealing with objects containing circular references.

stringifyWithWhitelist

• 这个npm包提供了一个名为stringifyWithWhitelist的方法，它可以让您将一个JavaScript对象转换成一个字符串，但只包括在白名单中的键路径。这个方法在处理包含循环引用的对象时，会用"[Circular]"标记循环引用。

安装

• 使用npm安装此包：

npm install stringify-with-whitelist

使用

• 首先，导入stringifyWithWhitelist方法：

const { stringifyWithWhitelist } = require('stringify-with-whitelist');

然后，您可以将任意JavaScript对象传递给stringifyWithWhitelist方法，并提供一个包含白名单键路径的数组，以便在转换为字符串时仅包含这些路径。

Copy code
const obj = {
  a: {
    b: {
      c: 1,
      d: 2
    },
    e: 3
  },
  f: [4, 5, 6]
};

const whitelist = ['a.b.c', 'a.e', 'f.*'];

const result = stringifyWithWhitelist(obj, whitelist);
console.log(result);
输出：

css
Copy code
{
  a: {
    b: {
      c: 1
    },
    e: 3
  },
  f: [
    4,
    5,
    6
  ]
}

API

• stringifyWithWhitelist(obj, whitelist)
  • obj (Object): 要转换为字符串的JavaScript对象。
  • whitelist (Array): 字符串数组，包含要包含在输出中的键路径。使用星号 () 表示数组元素。例如：'a.b.c', 'f.'。 返回值：一个字符串，表示经过白名单过滤的JavaScript对象。

注意：此方法在处理包含循环引用的对象时，会用"[Circular]"标记循环引用。
