# Zodish

**Zodish** is a schema parser and validator library heavily inspired
by JavaScript's [Zod](https://zod.dev).

```elixir
alias Zodish, as: Z

@schema Z.map(%{
          type:
            Z.enum([:person, :company])
            |> Z.coerce()
            |> Z.optional(default: :person),
          name: Z.string(trim: true, min: 1, max: 100),
          email: Z.email(),
          phone:
            Z.string(regex: {~r/^\+\d{7,15}$/, error: "invalid phone number"})
            |> Z.optional()
        })

def parse(input) do
  Z.parse(@schema, input)
end
```

## Roadmap / Next up

Here's a non-exhaustive list of feature that I intend to add in the
near future:

|        3 | Define what ports (enumerated or range) are allowed                                               | URI             |        |
|        3 | Generate JSON Schema from a Zodish schema                                                         |                 |        |
|        3 | Introduce a Schema Registry to make it easier to retrieve, reuse reference and manage schemas     |                 |        |
