# elm-validation
Tools for managing validity and error state of data, e.g. from user input.
## To install
```
$ elm install ericgj/elm-validation
```
## Example
Basic usage for validation in an HTML form.
view : Form -> Html Msg
view form =
div []
[ input
[ type_ "text"
, value
(form.input
|> Validation.toString identity
)
, onInput
(Validation.validate isRequired
>> SetInput
)
]
[]
, div
[ class "error" ]
[ text
(Validation.message form.input
|> Maybe.withDefault ""
)
]
]
Combining validation of form fields to determine overall validity of a model.
(For example, this could be used to determine if the submit button should be
enabled on the form.)
validateForm : Form -> ValidationResult Model
validateForm form =
Validation.valid Model
|> Validation.andMap form.field1
|> Validation.andMap form.field2
