Zod Integration

VonaJS has a large number of built-in argument pipes, which provide a very concise and flexible mechanism for request parameter validation based on Zod

• See: Validation

Example

Let's take the ArgNumber argument pipe created earlier as an example. The same functionality can be achieved using the built-in argument pipe as follows:

class ControllerStudent {
  @Web.get(':id')
- async findOne(@ArgNumber() @Arg.param('id') id: any) {}  
+ async findOne(@Arg.param('id') id: number) {}
}

Simply set the type of id to number

You can also explicitly specify the Zod Schema z.number()

import z from 'zod';

class ControllerStudent {
  @Web.get(':id')
+ async findOne(@Arg.param('id', z.number()) id: number) {}
}

Specify a minimum value:

import z from 'zod';

class ControllerStudent {
  @Web.get(':id')
+ async findOne(@Arg.param('id', z.number().min(1)) id: number) {}
}

Equivalent to:

import { v } from 'vona-module-a-openapi';

class ControllerStudent {
  @Web.get(':id')
+ async findOne(@Arg.param('id', v.min(1)) id: number) {}
}
