Verify email domains with Cognito. Prevent bad signups with email domain validation and Cognito PreSignUp triggers. By adding a Cognito PreSignUp trigger to validate email domains.
Mistyped emails can be a huge problem for user registrations. In this quick tip, I’ll show you how to prevent a huge percentage of such problems by adding a Cognito PreSignUp trigger to validate email domains.
At Narakeet, an online app lets users script narrated videos with markdown, about 10% of user registrations went into a black hole because people mistyped their email. I’ve probably seen every possible way to butcher ‘gmail’ in the email bounce logs.
Because users could not confirm the registration, they could not sign in and use the app. That made a very bad first impression. Visitors might think that the application is broken and never come back, instead of fixing their email during registration. To add insult to injury, with an invalid email, I would not be able to get in touch with them to provide assistance.
Cognito user pools can be customised with various triggers. The
PreSignUp trigger allows you to modify the sign-up process. Most of the examples online show how to speed up the user funnel, automatically confirming attributes and skipping steps of the usual registration process. However, we can also use this trigger to slow users down then they make a mistake.
Businesses need to understand serverless application with major pros and cons of serverless architecture, before deciding about serverless computing.
Bypass the complex middleware and consider a lightweight node.js implementation to deploy serverless functions from your mainframe CICS applications.
In the following lines, we’ll go through everything you need to create your own pipeline, connect it with other pipelines and maintain them only by running a not that complicated bash script. And by the end, you’ll probably come to realize yourself how awesome infrastructure as code is (no need to thank us).
Happy Serverless September 2020! We at Coding Sans love working with serverless technology. This is why we decided to publish a report with the latest serverless trends this year. We partnered up with nine other companies who share our love to make it happen.
