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。

我在我的snippet目录中创建了一个名为styles.js的文件，我认为它可以帮助任何想要导入单个文件的人。

这是对color.js的styles.js文件的一个小修改，帮助了我很多。

以下是该文件的内容:

// Original: https://github.com/Marak/colors.js/blob/master/lib/styles.js

const styleCodes = {
    // Reset all styles.
    reset: [0, 0],
    
    // Text styles.
    bold: [1, 22],
    dim: [2, 22],
    italic: [3, 23],
    underline: [4, 24],
    inverse: [7, 27],
    hidden: [8, 28],
    strikethrough: [9, 29],
    
    // Foregound classic colours.
    fgBlack: [30, 39],
    fgRed: [31, 39],
    fgGreen: [32, 39],
    fgYellow: [33, 39],
    fgBlue: [34, 39],
    fgMagenta: [35, 39],
    fgCyan: [36, 39],
    fgWhite: [37, 39],
    fgGray: [90, 39],
    
    // Foreground bright colours.
    fgBrightRed: [91, 39],
    fgBrightGreen: [92, 39],
    fgBrightYellow: [93, 39],
    fgBrightBlue: [94, 39],
    fgBrightMagenta: [95, 39],
    fgBrightCyan: [96, 39],
    fgBrightWhite: [97, 39],

    // Background basic colours.
    bgBlack: [40, 49],
    bgRed: [41, 49],
    bgGreen: [42, 49],
    bgYellow: [43, 49],
    bgBlue: [44, 49],
    bgMagenta: [45, 49],
    bgCyan: [46, 49],
    bgWhite: [47, 49],
    bgGray: [100, 49],
    bgGrey: [100, 49],
    
    // Background bright colours.
    bgBrightRed: [101, 49],
    bgBrightGreen: [102, 49],
    bgBrightYellow: [103, 49],
    bgBrightBlue: [104, 49],
    bgBrightMagenta: [105, 49],
    bgBrightCyan: [106, 49],
    bgBrightWhite: [107, 49],
};

// This object will contain the string representation for all style codes.
const styles = {};

// Loop over all the style codes and assign them to the `styles` object.
// 
// The a `styleCode` in the `styleCodes` object consists of two numbers:
// Index 0: The opening style code (In HTML this can be the opening <b> tag).
// Index 1: The closing style code (In HTML this can be the closing </b> tag).
for (let styleCode of Object.keys(styleCodes)) {
    styles[styleCode] = {
        open: `\x1B[${styleCodes[styleCode][0]}m`,
        close: `\x1B[${styleCodes[styleCode][1]}m`,
    };
}

module.exports = styles;

其实用起来很简单。

const styles = require("/path/to/styles.js");

// Let's say we've got an error:
const errorOpen = styles.bold.open + styles.bgRed.open + styles.fgWhite.open;
const errorClose = styles.reset.close; // Close everything
console.log(errorOpen, "ERROR", errorClose, ": Missing semicolon at line 9.");

根据这个文档，你可以根据输出的数据类型改变颜色:

// you'll need the util module
var util = require('util');

// let's look at the defaults: 
util.inspect.styles

{ special: 'cyan',
  number: 'yellow',
  boolean: 'yellow',
  undefined: 'grey',
  null: 'bold',
  string: 'green',
  date: 'magenta',
  regexp: 'red' }

// what are the predefined colors?
util.inspect.colors

{ bold: [ 1, 22 ],
  italic: [ 3, 23 ],
  underline: [ 4, 24 ],
  inverse: [ 7, 27 ],
  white: [ 37, 39 ],
  grey: [ 90, 39 ],
  black: [ 30, 39 ],
  blue: [ 34, 39 ],
  cyan: [ 36, 39 ],
  green: [ 32, 39 ],
  magenta: [ 35, 39 ],
  red: [ 31, 39 ],
  yellow: [ 33, 39 ] }

这些似乎是ANSI SGR转义码，其中第一个数字是在输出之前发出的代码，第二个数字是在输出之后发出的代码。因此，如果我们看一下维基百科上的ANSI SGR代码图表，你会发现大多数代码都以数字30-37开始设置前景色，以39结束重置为默认前景色。

我不喜欢的一点是有些颜色太深了。特别是日期。继续，在控制台中尝试new Date()。深色洋红色加黑色真的很难辨认。让我们把它换成浅洋红色。

// first define a new color
util.inspect.colors.lightmagenta = [95,39];

// now assign it to the output for date types
util.inspect.styles.date = 'lightmagenta';

现在，当您尝试new Date()时，输出的可读性大大提高。

如果你想在启动node时自动设置颜色，创建一个脚本来启动repl，就像这样:

// set your colors however desired
var util = require('util');
util.inspect.colors.lightmagenta = [95,39];
util.inspect.styles.date = 'lightmagenta';

// start the repl    
require('repl').start({});

保存这个文件(例如init.js)，然后运行node.exe init.js。它将设置颜色并启动node.js命令提示符。

(感谢loganfsmyth对repl想法的回答。)

这适用于(我所知道的)Node控制台。

该包是快捷方式，您可以使用此命令安装它。 Const short = require('@testgrandma/shortcuts');

您可以执行两个命令来更改颜色。它是RGB颜色和Hex颜色short.colorRGB(r,g,b);

short.colorhex(十六进制);

你可以执行console.log(short.colorhex('d50000') + 'This is red!');

包裹可以在这里找到。

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"
FgGray: "\x1b[100m"

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。

paint-console

简单的可着色原木。支持检查对象和单行更新 这个包只是重新油漆控制台。

安装

npm install paint-console

使用

require('paint-console');

console.info('console.info();');
console.warn('console.warn();');
console.error('console.error();');
console.log('console.log();');
