要链接横跨多行的CSS3样式，你可以这样做，

var styles = [
    'background: linear-gradient(#D33106, #571402)'
    , 'border: 1px solid #3E0E02'
    , 'color: white'
    , 'display: block'
    , 'text-shadow: 0 1px 0 rgba(0, 0, 0, 0.3)'
    , 'box-shadow: 0 1px 0 rgba(255, 255, 255, 0.4) inset, 0 5px 3px -5px rgba(0, 0, 0, 0.5), 0 -13px 5px -10px rgba(255, 255, 255, 0.4) inset'
    , 'line-height: 40px'
    , 'text-align: center'
    , 'font-weight: bold'
].join(';');

console.log('%c a spicy log message ?', styles);

欢呼。

我怀疑是否有人会真正看到它，但对于那些想要在同一条线上混合几种颜色的人，我有一个简单的解决方案:

export enum Colors {
    Black = '\033[30m',
    Red = '\x1b[31m',
    Green = '\x1b[32m',
    Yellow = '\x1b[33m',
    Blue = '\033[34m',
    Magenta = '\033[35m',
    Cyan = '\033[36m',
    White = '\033[37m'
}


function color(text: string, color: color: Colors) {
    return `${color}${text}\x1b[0m`;
}


console.log(`This is ${color('green text', Colors.Green)} but this is black. This is red ${color('red', Colors.Red)} etc`);

如果你想给你的终端控制台上色，那么你可以使用npm包粉笔

npm i chalk

选项1

// log-css.js v2
const log = console.log.bind()
const css = (text, options) => {
    let cssOptions = ''
    for (let prop in options) {
        const value = options[prop]
        prop = camelCaseToDashCase(prop)
        cssOptions += `${prop}: ${value}; `
    }
    return [`%c${text}`, cssOptions.trim()]

    function camelCaseToDashCase(value) {
        return value.replace(/[A-Z]/g, matched => `-${matched.toLowerCase()}`)
    }
}

例子:

log(...css('Example =P', {
    backgroundColor: 'blue',
    color: 'white',
    // fontFamily: 'Consolas',
    fontSize: '25px',
    fontWeight: '700',
    // lineHeight: '25px',
    padding: '7px 7px'
}))

选项2

我现在创建log-css.js https://codepen.io/luis7lobo9b/pen/QWyobwY

// log-css.js v1
const log = console.log.bind();
const css = function(item, color = '#fff', background = 'none', fontSize = '12px', fontWeight = 700, fontFamily) {
    return ['%c ' + item + ' ', 'color:' + color + ';background:' + background + ';font-size:' + fontSize + ';font-weight:' + fontWeight + (fontFamily ? ';font-family:' + fontFamily : '')];
};

例子:

log(...css('Lorem ipsum dolor sit amet, consectetur adipisicing elit.', 'rebeccapurple', '#000', '14px'));

模板系统，有用的，如果你想创建彩色的行文本，而不为每个块创建完整的风格

var tpl = 'background-color:greenyellow; border:3px solid orange; font-size:18px; font-weight: bold;padding:3px 5px;color:';
console.log('%cMagenta %cRed %cBlue', `${tpl} magenta`, `${tpl} Red`,`${tpl} #4274fb`);

有一系列内置函数用于为控制台日志上色:

//For pink background and red text
console.error("Hello World");  

//For yellow background and brown text
console.warn("Hello World");  

//For just a INFO symbol at the beginning of the text
console.info("Hello World");  

//for custom colored text
console.log('%cHello World','color:blue');
//here blue could be replaced by any color code

//for custom colored text with custom background text
console.log('%cHello World','background:red;color:#fff')
