Zod

Summary

This sample shows the usage of Zod to eliminate manual cast and validation of the data coming from external API (e.g. SharePoint REST API, Graph API, etc.).

I have a Form Results list that has these columns:

Column	Type
Title	Single line of text
Description	Multiple lines of text
Qty	Number (> 0)
Rating	Number (1 - 10)
Email	Single line of text
Status	Choice
PublishDate	Date
Contact	Person

When we get list items data from SharePoint REST API. It would be better to have fully typed data to eliminate runtime error and also make it easier to process the data in TypeScript.

So I used Zod to automatically cast and validate type of the data.

Below is example on how to setup the schema for my data above (Model.ts):

We can also generate TypeScript Type from the schema (See FormResultModel and FormResultsModel).

Below is how to cast and validate data based on the schema (SharePointHelper.ts):

That line of code will do the following:

• Cast
  • Id as number
  • Title as string
  • Description as string
  • IsActive as boolean
  • Qty as number
  • Rating as number
  • Email as string
  • Status as string
  • PublishDate as string
  • Contact as object
• Validate
  • Qty should be non negative
  • Rating should be between 1 - 10
  • Email should be valid email
  • Status should be "Active", "Done", or "Rejected"
• Transform
  • PublishDate to be DateTime
  • Contact to be Contact.Title value from API

Below is the result type from the parse operation:

When it's failed to parse (wrong type or not pass validation), it will throw error. In this example I just simple render error message when it happens.

In this example, I used the parsed result data to be displayed on a DetailsList component
