Performance

Zod discriminated unions are performant and can be used in production applications because they are built on top of the fast and efficient zod library. Zod is a popular data validation library for JavaScript that is used by many large companies, including Netflix, Airbnb, and Uber. Zod discriminated unions leverage the performance of zod to provide fast and efficient data validation.

In addition to being performant, zod discriminated unions are also very easy to use. They provide a simple and intuitive API that makes it easy to define and validate data. This makes zod discriminated unions a great choice for developers who want to quickly and easily add data validation to their applications.

const userSchema = z.object({ name: z.string(), email: z.string().email(), password: z.string().min(8), }); const user = userSchema.parse({ name: "John Doe", email: "", password: "password123", });

In this example, the userSchema is used to define the expected shape of a user object. The user object is then parsed using the userSchema to ensure that it is in the correct format and that it contains all of the required data. If the user object is valid, it will be returned as a zod discriminated union. Otherwise, an error will be thrown.

if (user.isValid()) { // The user object is valid. } else { // The user object is invalid. }
