最小的别名:

{
  const f = (color) => (...args) => {
    for (const x of [color, ...args, "\33[0m"]) console.log(x);
  };

  Object.assign(console, {
    black: f("\33[30m"),
    red: f("\33[31m"),
    green: f("\33[32m"),
    yellow: f("\33[33m"),
    blue: f("\33[34m"),
    magenta: f("\33[35m"),
    cyan: f("\33[36m"),
    white: f("\33[37m"),
  });
}

// Usage
console.blue("Blue world");

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:

日志/索引.js

const colors = {
    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",

    BgBlack : "\x1b[40m",
    BgRed : "\x1b[41m",
    BgGreen : "\x1b[42m",
    BgYellow : "\x1b[43m",
    BgBlue : "\x1b[44m",
    BgMagenta : "\x1b[45m",
    BgCyan : "\x1b[46m",
    BgWhite : "\x1b[47m",
};

module.exports = () => {
    Object.keys(colors).forEach(key => {
        console['log' + key] = (strg) => {
            if(typeof strg === 'object') strg = JSON.stringify(strg, null, 4);
            return console.log(colors[key]+strg+'\x1b[0m');
        }
    });
}

app.js

require('./logger')();

然后这样使用它:

console.logBgGreen(" grüner Hintergrund ")

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'));

视图Coolors模块

我为不能有依赖的npm脚本写了一个方便的一行代码:

Const {r, g, b, w, c, m, y, k} = [ ['r'， 1]， ['g'， 2]， ['b'， 4]， ['w'， 7]， ['c'， 6]， ['m'， 5]， ['y'， 3]， ['k'， 0]， ]．Reduce ((cols, col) => ({ .．.关口,[坳[0]]:f = > ' \ x1b[3{坳[1]}美元$ {f} \ x1b [0 m ' }, {}) console.log(' ${g('I')} love ${r('Italy')} ')

R,g,b,w,c,m,y,k分别代表红色，绿色，蓝色，白色，青色，品红，黄色和黑色。

这在一定程度上取决于你所在的平台。最常见的方式 要做到这一点，需要打印ANSI转义序列。举个简单的例子， 下面是blender构建脚本中的一些python代码:

// This is a object for use ANSI escape to color the text in the terminal
const bColors = {
    HEADER    : '\033[95m',
    OKBLUE    : '\033[94m',
    OKGREEN   : '\033[92m',
    WARNING   : '\033[93m',
    FAIL      : '\033[91m',
    ENDC      : '\033[0m', 
    BOLD      : '\033[1m',   
    UNDERLINE : '\033[4m'
}

要使用这样的代码，可以执行如下操作

console.log(`${bColors.WARNING} My name is sami ${bColors.ENDC}`)
