How to convert rgb color in string (E.g. rgb(0, 164, 255) to hex value in TypeScript

Answer 1

const rgbString: string = "rgb(0, 164, 255)";

let matchResult: any = rgbString.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);
console.log(matchResult + "\n");

delete(matchResult[0]);
for (let i: number = 1; i <= 3; i++) {
    matchResult[i] = parseInt(matchResult[i]).toString(16);
    if (matchResult[i].length == 1) {
        matchResult[i] = '0' + matchResult[i];
    }
} 

const hexString: string ='#' + matchResult.join('').toUpperCase(); 

console.log(hexString);
   
   
   
/*
run:
   
rgb(0, 164, 255),0,164,255
 
#00A4FF
   
*/
