Hyperlambda validators

Trusting frontend validation logic is like trusting a thief when he says he won't steal your wallet.

Hyperlambda validators

Trusting frontend validation logic is like trusting a thief when he says he won't steal your wallet. Frontend validation is for convenience, to reduce HTTP requests, not for ensuring data quality. You can add TypeScript validators until your face turns red, and the moment some guy creates another frontend to consume your API, your validators are basically useless. Hyperlambda validators on the other side are executing on your server, which makes them much more valuable.

Data quality and Hyperlambda validators

I have worked with 50+ companies during my 25+ years as en enterprise software developer. Most of these companies struggled with poor data quality. Phone numbers would be written like; "John Doe", or "foo@bar.com". Manually going through 500,000 records to clean up garbage data is literally impossible. This reduces the data quality your employer has. Which again results in more trouble doing business, leads to less profit and leads to less salary for you. Data quality IS KING!

In the following video I am illustrating how to create server side validators with Hyperlambda, which is a much better alternative if you're to chose only one. If you want to follow the video hands on, you can register a Magic cloudlet here.

Adding server side validation ensures data quality, assuming all data goes in and out of your database through your backend API. This results in higher data quality over time, which again results in better business.

Only relying upon frontend validators created with for instance React or Angular, is asking for trouble. Very soon somebody will want to create another frontend client using for instance Swift or the Android SDK. As they do, they're going to bypass your validator logic. If they do, you will end up with garbage data in your database.

DO NOT trust frontend validators (alone!) - Because they're "mostly useless" from a data quality perspective

With Hyperlambda you've got validators for every imaginable purpose, ranging from email validators to regular expression validators. Don't trust users of your web API to supply you valid data, ensure it using validators.
