Number one this week, Zod is a library to validate user input against composable schemas.

It shines with its TypeScript powerful features. The main benefit of using Zod over other solutions like Yup is:

Eliminating the need to define static types and runtime validators separately.

Often, the shape of the objects to validate is written at 2 different places:

• static types provided by TypeScript, used to validate at compile time
• schema used to validate data at run time

Using Zot schemas, you don’t have to write types, you can access the type of a schema using zod.TypeOf like this:

const projectSchema = zod.object({
  name: zod.string(),
  stars: zod.number()
});

type Project = zod.TypeOf<typeof ProjectSchema>

One more thing: besides the invisible enemy that spreads fear all over the world, the biggest news of the week for the JavaScript community is the acquisition of NPM by GitHub.

With this merger comes exciting new planned features such as support for “Workspaces” and other improvements!
