===========

[](#phel-schema)

Schema validation library in phel. The library inspired by zod

Basic Usage
-----------

[](#basic-usage)

Creating a simple string schema

```
(ns app
  (:require phel\schema :as z))

# creating a schema for strings
(def my-schema (z/string))

# parsing
(z/parse my-schema "tuna") # => "tuna"
(z/parse my-schema 12) # => throws ZodError

# "safe" parsing (doesn't throw error if validation fails)
(z/safe-parse my-schema "tuna") # => {:success true :data "tuna"}
(z/safe-parse my-schema 12) # => {:success false :error ZodError :issues [...]}
```

```
(ns app
  (:require phel\schema :as z))

# creating a schema for strings
(def my-schema (as-> (z/string) s
                     (z/min s 3)
                     (z/max s 10)
                     (z/regex s "/^t/")))

# parsing
(z/parse my-schema "tuna") # => "tuna"
(z/parse my-schema "a tuna") # => throws ZodError
```

Creating an object schema

```
(ns app
  (:require phel\schema :as z))

(def user-schama (z/object {
  :username (z/string)
}))

(z/parse user-schama {:username "Ludwig"})
```
