@halo-lab/vue-form

The package supports simple form services such as Formspree.io, Formsubmit.co, W3Form. All you need is either provide URL address for the form submission, or submit callback function to the Form component. If chosen form service accepts the hidden input with any information, e.g. api key, you can add it as Input component with the name you need and the parameter defaultValue.

To install the package

yarn add @halo-lab/vue-form

npm install @halo-lab/vue-form
