``bash
npm install --save check-base-encoding

Or on the client side,

`html

`

$3

`javascript
var checkBase = require('check-base-encoding');

// Following examples yield true as the output
console.log(checkBase.isBase64('SGV5IG1hbiB3aGF0J3MgdQ=='));

console.log(checkBase.isBase64URL('WW8geW8gY2hlY2s='));

console.log(checkBase.isBase58('brXijP'));

console.log(checkBase.isBase32('JBSXSIDNMFXCYIDX'));

console.log(checkBase.isBase32Hex('ETK68TBHCHI68==='));

console.log(checkBase.isHex('736E646964'));

// If your string is not padded (in the case of first four functions),
// you need to pass a second argument true which enforces no padding

// Following is the example of a VAPID key
console.log(checkBase.isBase64URL('InhF137RBd4GPsDxlIoO6P_aCRaO9WspxraTJwiqjxY', true));
// --> true
