Astro Reactive Form
Generate a dynamic form based on your data, and modify programatically.

Installation

In your Astro project:

npm i astro-reactive-form

Usage

Use in an Astro page:

---
import { FormControl, FormGroup } from "astro-reactive-form/core";
import Form from "astro-reactive-form";

// create a form group
const form = new FormGroup([
  {
    name: "username",
    label: "Username",
  },
  {
    name: "password",
    label: "Password",
    type: "password",
  },
]);

// set the name optionally
form.name = "Simple Form";

// you can insert a control at any point
form.controls.push(
  new FormControl({
    type: "checkbox",
    name: "is-awesome",
    label: "is Awesome?",
    labelPosition: "right",
  })
);

// you can get a FormControl object
const userNameControl = form.get("username");

// you can set values dynamically
userNameControl?.setValue("RAMOOOON");
form.get('is-awesome')?.setValue("checked");
---

<!-- 
  the `formGroups` attribute can take a single FormGroup
  or an array of FormGroup for multiple fieldsets;
  we do a single for now in this example
-->
<Form
  formGroups={form}
  submitControl={{
    type: "submit",
    name: "submit",
  }}
/>

Future Plans

Currently this only supports very basic form creation, but the goal of the project is ambitious:

1. Validator library for common validation scenarios
   1. Client-side validation
   2. Server-side validation
   3. validation hooks - onFocus, onBlur, onSubmit
2. Themes - unstyled, light mode, dark mode, compact, large
3. FormGroup class
   1. statusChanges - observable that emits the form status when it changes
   2. valueChanges - observable that emits the values of all controls when they change
4. FormControl class
   1. statusChanges - observable that emits the control status when it changes
   2. valueChanges - observable that emits the control value when it changes
5. Documentation website

... and so much more
