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');

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

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。

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。

我真的很喜欢@Daniel的回答，但是console.log{color}函数的工作方式与常规的console.log不同。我做了一些更改，现在所有参数的新函数将被传递到console.log(以及颜色代码)。

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",
};

const enableColorLogging = function(){
    Object.keys(_colors).forEach(key => {
        console['log' + key] = function(){
            return console.log(_colors[key], ...arguments, _colors.Reset);
        }
    });
}

你也可以使用颜色。

用法:

var cw = require('colorworks').create();
console.info(cw.compile('[[red|Red message with a [[yellow|yellow]] word.]]'));

为了简化工作，您还可以使用它创建一个函数。

function say(msg) {
  console.info(cw.compile(msg));
}

现在你可以做:

say(`[[yellow|Time spent: [[green|${time}]]ms.]]`);
