Examples

Three examples showing some useage examples of the library.

• cli - validating flag input in a command line application
• http-inline - simple stdlib http server, showing request validation within a handler
• http-validate - sample of using an error handler combined with the validation.Validator interface

To test them, just run go run main.go targeting the relevant directory.

For the http servers, an example valid POST request is:

POST http://localhost:1234/

{
    "name":"My Name",
    "dob":"2000-10-12T07:20:50.52Z",
    "count":1,
    "isEnabled":false
}

An invalid request:

POST http://localhost:1234/

{
    "name":"My Name",
    "dob":"2000-10-12T07:20:50.52Z",
    "count":0,
    "isEnabled":true
}

The invalid request will then return this response with a 400 status code:

{
    "errors": {
        "count": [
            "value 0 should be greater than 0"
        ],
        "isEnabled": [
            "value true does not evaluate to false"
        ]
    }
}
