This worked for me :

var CryptoJS = require("crypto-js");
const raw_signature = hmacSHA1(baseString, signingKey);
const signature = raw_signature.toString(CryptoJS.enc.Base64);

It's giving the exact same result as, in PHP, :

$rawSignature = hash_hmac("sha1", $baseString, $signingKey, true);
$signature    = base64_encode($rawSignature);
