Validating certificate using NodeJs Crypto

I'm running a sever in NodeJs whose certificate will be stored in DB as a string (for security purposes). I would like to validate it and it's expiration date, how can I do that?

I looked into 'Crypto' but I could not find a method that can do that.

For example:

-----BEGIN CERTIFICATE-----
MIIDNTCCAh2gAwIBAgIUJqrw/9EDZbp4DExaLjh0vSAHyBgwDQYJKoZIhvcNAQEL
BQAwFjEUMBIGA1UEAxMLbXl2YXVsdC5jb20wHhcNMTcxMjA4MTkyMzIwWhcNMjcx
MjA2MTkyMzQ5WjAWMRQwEgYDVQQDEwtteXZhdWx0LmNvbTCCASIwDQYJKoZIhvcN
AQEBBQADggEPADCCAQoCggEBAKY/vJ6sRFym+yFYUneoVtDmOCaDKAQiGzQw0IXL

-----END CERTIFICATE-----

Resolved the issue by using package x509.

https://www.npmjs.com/package/x509

const x509 = require('x509');
var cert = x509.parseCert(__dirname + '/certs/nodejitsu.com.crt');
/*
cert = { subject:
   { countryName: 'US',
     postalCode: '10010',
     stateOrProvinceName: 'NY',
     localityName: 'New York',
     streetAddress: '902 Broadway, 4th Floor',
     organizationName: 'Nodejitsu',
     organizationalUnitName: 'PremiumSSL Wildcard',
     commonName: '*.nodejitsu.com' },
  issuer:
   { countryName: 'GB',
     stateOrProvinceName: 'Greater Manchester',
