## Installation
|
|
In your [Astro](https://astro.build) project:
|
|
|
|
```
|
|
npm i @astro-reactive/validator @astro-reactive/form
|
|
```
|
|
|
|
## Usage
|
|
Use in an Astro page:
|
|
|
|
```astro
|
|
---
|
|
import Form, { FormControl, FormGroup } from "@astro-reactive/form";
|
|
import { Validators } from "@astro-reactive/validator";
|
|
|
|
const form = new FormGroup([
|
|
{
|
|
name: "username",
|
|
label: "Username",
|
|
validators: [Validators.required],
|
|
},
|
|
{
|
|
name: "email",
|
|
label: "Email",
|
|
validators: [Validators.email, Validators.required],
|
|
},
|
|
{
|
|
name: "password",
|
|
label: "Password",
|
|
type: "password",
|
|
validators: [Validators.required, Validators.minLength(8)],
|
|
},
|
|
]);
|
|
|
|
// you can insert a control at any point
|
|
form.controls.push(
|
|
new FormControl({
|
|
type: "checkbox",
|
|
name: "is-awesome",
|
|
label: "is Awesome?",
|
|
})
|
|
);
|
|
|
|
---
|
|
|
|
<Form showValidationHints formGroups={form} />
|
|
<!--
|
|
The `showValidationHints` attribute tells the Form component
|
|
that you want to render validation hints. So far, these are:
|
|
1. asterisks on required controls' labels
|
|
2. controls with errors will become color red
|
|
|
|
This property is optional and set to false by default,
|
|
which keeps the Form component unstyled,
|
|
and gives you have the freedom to style it yourself.
|
|
-->
|
|
```
|
|
|
|
👉 For more examples and explanations of the component properties, see the [Validators API Docs](https://astro-reactive-docs.netlify.app/en/api/validator/validators/).
