我创建了自己的模块StyleMe。我这样做，我可以用很少的打字做很多事情。例子:

var StyleMe = require('styleme');
StyleMe.extend() // extend the string prototype

console.log("gre{Hello} blu{world}!".styleMe()) // Logs hello world! with 'hello' being green, and 'world' being blue with '!' being normal.

它也可以被嵌套:

console.log("This is normal red{this is red blu{this is blue} back to red}".styleMe())

或者，如果你不想扩展字符串原型，你可以选择其他3个选项:

console.log(styleme.red("a string"))
console.log("Hello, this is yellow text".yellow().end())
console.log(styleme.style("some text","red,bbl"))

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(", "));

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");

这是控制台中可用颜色(包括背景和前景)的列表，带有一些可用的操作(如重置，反转等)。

const colours = {
    reset: "\x1b[0m",
    bright: "\x1b[1m",
    dim: "\x1b[2m",
    underscore: "\x1b[4m",
    blink: "\x1b[5m",
    reverse: "\x1b[7m",
    hidden: "\x1b[8m",
    
    fg: {
        black: "\x1b[30m",
        red: "\x1b[31m",
        green: "\x1b[32m",
        yellow: "\x1b[33m",
        blue: "\x1b[34m",
        magenta: "\x1b[35m",
        cyan: "\x1b[36m",
        white: "\x1b[37m",
        gray: "\x1b[90m",
        crimson: "\x1b[38m" // Scarlet
    },
    bg: {
        black: "\x1b[40m",
        red: "\x1b[41m",
        green: "\x1b[42m",
        yellow: "\x1b[43m",
        blue: "\x1b[44m",
        magenta: "\x1b[45m",
        cyan: "\x1b[46m",
        white: "\x1b[47m",
        gray: "\x1b[100m",
        crimson: "\x1b[48m"
    }
};

下面是一个如何使用它的例子:

console.log(colours.bg.blue, colours.fg.white, "I am a white message with a blue background", colours.reset) ; 
// Make sure that you don't forget "colours.reset" at the so that you can reset the console back to it's original colours.

或者你可以安装一些实用模块:

npm install console-info console-warn console-error --save-dev

当你使用这些模块时，它们会在控制台显示如下内容:

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'));

Coolors

它非常适合使用或扩展。你可以简单地使用:

var coolors = require('coolors');
console.log(coolors('My cool console log', 'red'));

或者使用config:

var coolors = require('coolors');
console.log(coolors('My cool console log', {
   text: 'yellow',
   background: 'red',
   bold: true,
   underline: true,
   inverse: true,
   strikethrough: true
}));

延伸一下似乎很有趣:

var coolors = require('coolors');
function rainbowLog(msg){
    var colorsText = coolors.availableStyles().text;
    var rainbowColors = colorsText.splice(3);
    var lengthRainbowColors = rainbowColors.length;
    var msgInLetters = msg.split('');
    var rainbowEndText = '';
    var i = 0;
    msgInLetters.forEach(function(letter){
        if(letter != ' '){
            if(i === lengthRainbowColors) i = 0;
            rainbowEndText += coolors(letter, rainbowColors[i]);
            i++;
        }else{
            rainbowEndText += ' ';
        }
    });
    return rainbowEndText;
}
coolors.addPlugin('rainbow', rainbowLog);
console.log(coolorsExtended('This its a creative example extending core with a cool rainbown style', 'rainbown'));
