Rebuild static website on content change

If someone want to use the new DO serverless functions:

function main(args) {
  const https = require('https');
  const url = 'https://api.digitalocean.com/v2/apps/fda88e43-3e89-46e1-bbac-d4c25993fda6/deployments';
  const data = JSON.stringify({"force_build": true});

  const options = {
    host: 'api.digitalocean.com',
    port: 443,
    path: '/v2/apps/<APP_ID>/deployments',
    method: 'POST',
    headers: {
      'Authorization': 'Bearer <TOKEN>',
      'Content-Type': 'application/json',
      'Content-Length': data.length
    }
  };

  var req = https.request(options, function(res) {
    console.log("statusCode: ", res.statusCode);
    console.log("headers: ", res.headers);

    res.on('data', function(d) {
      process.stdout.write(d);
    });
  });

  req.write(data); // Write the request body
  req.end();
}

With the new DO serverless functions you could receive the Strapi webhook request and then trigger the deployment.
