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);

如果你想改变颜色直接自己没有模块尝试

console.log('\x1b[36m', 'sometext' ,'\x1b[0m');

先\x1b[36m改变颜色为36，然后回到终端颜色0。

下面是ANSI颜色代码列表

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。

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.");
