Using AWS Certificate Manager SDK to provision a certificate

aws-provision-certificate.ts

const accessKeyId = process.env.AWS_ACCESS_KEY_ID;
const secretAccessKey = process.env.AWS_SECRET_ACCESS_KEY;
const acm = new ACM({
  credentials: async () => ({ accessKeyId, secretAccessKey }),
  region: 'us-east-1'
});

const { CertificateArn } = await acm.requestCertificate({
  DomainName: <<DOMAIN_NAME>>,
  ValidationMethod: ValidationMethod.DNS
});

if (CertificateArn) {
  domain.certificateARN = CertificateArn;

  const certificate = await acm.describeCertificate({ CertificateArn });
  if (certificate && certificate.Certificate) {
    const validationDetails = certificate.Certificate.DomainValidationOptions?.find(item => item.DomainName === domain.name && item.ValidationMethod === ValidationMethod.DNS);
    if (validationDetails && validationDetails.ResourceRecord) {
      const { Name, Value } = validationDetails.ResourceRecord;
      // Use Name and Value for the CNAME record
    }
  }
