HOW TINY? const sendGridConfig = {api_user: 'SENDGRID_USERNAME', api_key: 'SENDGRID_PASSWORD'}; const transporter = nodemailer.createTransport(sgTransport({auth: sendGridConfig})); const sendMail = pify(transporter.sendMail); exports.handler = function(event, context) { const templateDir = path.join(__dirname, 'templates', event.template); const template = new EmailTemplate(templateDir); const render = pify(template.render); template.render(event.context) .then(result => { event.text = result.text; event.html = result.html; return sendMailAsync(event); }) .then(() => context.done(null, {message: 'Yaay success'}))) .catch(() => context.done(new Error('Something went wrong!'))); };

COMBINING STATIC SITES AND SERVERLESS Isolated services improve security Easy caching Every dynamic function is a limited Dynamic resources are hidden behind service with only the necessary permissions. APIs and well defined routes everything else can be cached. Great performance Easy maintenance Static things are instant; dynamic Most services can be handled by 3rd things are fast. parties requiring no maintenance.
