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'));

我不想要任何依赖于此，只有这些在OS x上为我工作。所有其他示例从这里的答案给了我八进制文字错误。

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"

Reset: "\x1b[0m"

例如，如果你想有一个昏暗的红色文本和蓝色背景，你可以在Javascript中这样做:

console.log("\x1b[2m", "\x1b[31m", "\x1b[44m", "Sample Text", "\x1b[0m");

颜色和效果的顺序似乎不是那么重要，但总是记得在最后重置颜色和效果。

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}`)

node-colorify

提供功能打印文本的颜色，也做文本格式，如粗体，闪烁等。

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:
