如何更改node.js的控制台字体颜色?

node.js

由于眼睛的问题,我不得不将控制台的背景颜色更改为白色,但是字体为灰色,这使消息不可读。我该如何更改?

在下面,您可以找到运行node.js应用程序时命令的文本颜色参考:

console.log('\x1b[36m%s\x1b[0m', 'I am cyan');  //cyan
console.log('\x1b[33m%s\x1b[0m', stringToMakeYellow);  //yellow

注意,%s是在字符串(第二个参数)中注入的位置。\x1b[0m重置终端颜色,以便在此之后不再继续成为所选颜色。

颜色参考

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"

编辑:

例如,\x1b[31m是一个 转义序列 ,它将被您的终端截获并指示其切换为红色。实际上,\x1b不可打印控制字符
的代码escape。仅处理颜色和样式的转义序列也称为
ANSI转义代码,
并且已标准化,因此(应)在任何平台上都可以使用。
