由于眼睛的问题,我不得不将控制台背景色改为白色,但字体是灰色的,它使消息无法阅读。我怎样才能改变呢?

Coolors
它非常适合使用或扩展。你可以简单地使用:
var coolors = require('coolors');
console.log(coolors('My cool console log', 'red'));
或者使用config:
var coolors = require('coolors');
console.log(coolors('My cool console log', {
text: 'yellow',
background: 'red',
bold: true,
underline: true,
inverse: true,
strikethrough: true
}));
延伸一下似乎很有趣:
var coolors = require('coolors');
function rainbowLog(msg){
var colorsText = coolors.availableStyles().text;
var rainbowColors = colorsText.splice(3);
var lengthRainbowColors = rainbowColors.length;
var msgInLetters = msg.split('');
var rainbowEndText = '';
var i = 0;
msgInLetters.forEach(function(letter){
if(letter != ' '){
if(i === lengthRainbowColors) i = 0;
rainbowEndText += coolors(letter, rainbowColors[i]);
i++;
}else{
rainbowEndText += ' ';
}
});
return rainbowEndText;
}
coolors.addPlugin('rainbow', rainbowLog);
console.log(coolorsExtended('This its a creative example extending core with a cool rainbown style', 'rainbown'));

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。
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);
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。

另一种方法是使用一个简单的ANSI代码生成器。
您不需要安装软件包 不需要搜索颜色代码,只需点击按钮
