如果你想保持简单，而不使用任何外部模块/学习新的api /破解核心控制台功能:

const LCERROR = '\x1b[31m%s\x1b[0m'; //red
const LCWARN = '\x1b[33m%s\x1b[0m'; //yellow
const LCINFO = '\x1b[36m%s\x1b[0m'; //cyan
const LCSUCCESS = '\x1b[32m%s\x1b[0m'; //green

const logger = class {
  static error(message, ...optionalParams) { console.error(LCERROR, message, ...optionalParams) }
  static warn(message, ...optionalParams) { console.warn(LCWARN, message, ...optionalParams) }
  static info(message, ...optionalParams) { console.info(LCINFO, message, ...optionalParams) }
  static success(message, ...optionalParams) { console.info(LCSUCCESS, message, ...optionalParams) }
}

// then instead (as presented in the accepted answer)
// console.error(LCERROR, 'Error message in red.');
// you write:

logger.error('Error message in red.');

// or with multiple parameters (only the message will be red):

logger.error('Error message in red.', 1, false, null, {someKey: 'whatever'});

// or use backticks (template literal) instead multiple params:

logger.error(`This will be red as ${foo} and ${bar} too.`);

现在您可以像使用控制台一样使用记录器。没有新的API需要记住……通常你会把它放到一个模块(logger.js)中，并导出类，以便在你的应用程序中随处使用它，因为const logger = require('./logger');

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"

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(", "));

If you are using Windows CMD then go to the terminal Properties/Colors (CMD top left) and then redefine the RGB value of the offensive color. In my case I believe it's the fifth color square from the left, which I changed to (222,222,222). It does not matter if the currently selected radio button shows Screen Text or Screen Background as you just redefine that specific "system" color. Once you changed the color don't forget to select back the preferred color for the background or text before clicking OK.

更改后，所有来自Node(在我的情况下是Ember)的红色消息都清晰可见。

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);

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();');
