另一种方法是使用一个简单的ANSI代码生成器。

您不需要安装软件包 不需要搜索颜色代码，只需点击按钮

在Node.js中有多个可用于格式化控制台文本的包。最流行的有:

粉笔, cli-color - 颜色- >编辑:颜色不再推荐，因为它有拒绝服务漏洞 详情见:https://snyk.io/blog/open-source-npm-packages-colors-faker/

用法:

粉笔:

const chalk = require('chalk');
console.log(chalk.red('Text in red'));

CLI-COLOR:

const clc = require('cli-color');
console.log(clc.red('Text in red'));

在ubuntu中，你可以简单地使用颜色代码:

var sys = require('sys');
process.stdout.write("x1B[31m" + your_message_in_red + "\x1B[0m\r\n");

我发现上面的答案(https://stackoverflow.com/a/41407246/4808079)非常有用，但不完整。如果你只想给某样东西上色一次，我想这没问题，但我认为以可运行的函数形式共享它更适用于现实生活中的用例。

const Color = {
  Reset: "\x1b[0m",
  Bright: "\x1b[1m",
  Dim: "\x1b[2m",
  Underscore: "\x1b[4m",
  Blink: "\x1b[5m",
  Reverse: "\x1b[7m",
  Hidden: "\x1b[8m",
  
  FgBlack: "\x1b[30m",
  FgRed: "\x1b[31m",
  FgGreen: "\x1b[32m",
  FgYellow: "\x1b[33m",
  FgBlue: "\x1b[34m",
  FgMagenta: "\x1b[35m",
  FgCyan: "\x1b[36m",
  FgWhite: "\x1b[37m",
  FgGray: "\x1b[90m",
  
  BgBlack: "\x1b[40m",
  BgRed: "\x1b[41m",
  BgGreen: "\x1b[42m",
  BgYellow: "\x1b[43m",
  BgBlue: "\x1b[44m",
  BgMagenta: "\x1b[45m",
  BgCyan: "\x1b[46m",
  BgWhite: "\x1b[47m"
  BgGray: "\x1b[100m",
}

function colorString(color, string) {
  return `${color}${string}${Color.Reset}`;
}

function colorLog(color, ...args) {
  console.log(...args.map(
   (it) => typeof it === "string" ? colorString(color, string) : it
  ));
}

像这样使用它:

colorLog(Color.FgYellow, "Some Yellow text to console log", { someObj: true });

console.log([
  colorString(Color.FgRed, "red"),
  colorString(Color.FgGreen, "green"),
  colorString(Color.FgBlue, "blue"),
].join(", "));

If you are using Windows CMD then go to the terminal Properties/Colors (CMD top left) and then redefine the RGB value of the offensive color. In my case I believe it's the fifth color square from the left, which I changed to (222,222,222). It does not matter if the currently selected radio button shows Screen Text or Screen Background as you just redefine that specific "system" color. Once you changed the color don't forget to select back the preferred color for the background or text before clicking OK.

更改后，所有来自Node(在我的情况下是Ember)的红色消息都清晰可见。

内联typescript解决方案

export const color = (function (colors) {
    const fn = (code: number, str: string) => `\x1b[${code}m${str}\x1b[39m`;
    const obj = { grey: fn.bind(null, 90) };
    for (let i = 0; i < colors.length; i++) obj[colors[i]] = fn.bind(null, 30 + i);
    return obj as { [K in typeof colors[any] | 'grey']: (str: string) => string };
})(['black', 'red', 'green', 'yellow', 'blue', 'magenta', 'cyan', 'white'] as const);
