# About LetsForm
**LetsForm** is an open source tool to generate React forms with simple JSON schemas using native UI components: Material UI, AntD, RSuite, ReactBootstrap, Mantine or just React

* **forget tedious boilerplate** copy and paste everytime you need to add a field. No more copy and paste from old code

* build the form **visually** with [LetsForm designer](https://designer.letsform.dev)

* based on the performant **React Hook Form**, no more unwanted re-renders even with complex forms

* keep **visual consistency** of the form, with a JSON form schema all forms are rendered in the same way across all pages,
with the same margins, colors, customizations and components.

* [validation](https://letsform.dev/advanced/validation) out of the box with **i18n** and scripting support

* [multi-language](https://letsform.dev/lets-form-designer/automatic-translations) **(i18n) support** and
[automatic translations of i18n tokens](https://letsform.dev/lets-form-designer/i18n-support#autocomplete-translations)

* [implement dynamic forms](https://letsform.dev/advanced/form-scripts) with the language you love - JavaScript -
and a simple set of instructions

* use **form features you will certainly need** in every project like splitting the form in
[tabs](https://letsform.dev/components/tabs#tabs), [steps](https://letsform.dev/components/steps),
[collapsible groups](https://letsform.dev/components/group) or [columns](https://letsform.dev/components/two-columns)

* easily switch **form modes**: [editable, disabled, read only and plaintext](https://letsform.dev/advanced/form-modes)
(you will never have to write form confirmation views)

* [support for arrays](https://letsform.dev/components/array), just define the fields of the array and you'll get the
**UI to add, remove and validate** the items in the array

* over **30** [components](https://letsform.dev/components-matrix) with consistent behaviour and properties

* full set of [helpers](https://letsform.dev/advanced/helpers) to **programmatically interact** with JSON form schemas

* **toolchain** to organize your forms in [projects](https://letsform.dev/lets-form-designer/projects) with
[versioning](https://letsform.dev/lets-form-designer/versioning) and integration with
[GitHub](https://letsform.dev/lets-form-designer/export-to-github), [NPM](https://letsform.dev/lets-form-designer/export-to-npm)
or your [repository](https://letsform.dev/lets-form-designer/export-to-file)

* **leverage** [ready-to-use and useful form templates](https://letsform.dev//lets-form-designer/templates) (like cascading
drop downs of all countries and provinces in all languages or credit card with validation)

* JSON forms can be **created programmatically**, for example in those use cases where a form is defined after introspection
of a data scheme (database table, GraphQL schema, etc.)

# Getting started
Install LetsForm

```
npm i lets-form -D
```

then try a simple JSON form schema with just one text field (or use the [LetsForm Designer](https://designer.letsform.dev) to create one), for example using **RSuite** components

```js
import React from 'react';
import LetsForm from 'lets-form/react-rsuite5';
// or /react-antd or /react-bootstrap or /react-material-ui or /react-mantine or /react
// see https://letsform.dev/docs for more info about specific frameworks

import 'rsuite/dist/rsuite.min.css';

// copied and pasted from LetsForm Designer
const MY_FORM = {
  "$schema": "https://cdn.jsdelivr.net/npm/lets-form/schemas/react-rsuite5/form.json",
  "version": 1,
  "layout": "vertical",
  "validationMode": "onSubmit",
  "fluid": true,
  "fields": [
    {
      "component": "input-text",
      "label": "My Field",
      "name": "my_field"
    }
  ],
  "name": "Simplest example"
};

const MyView = () => {
  return (
    <LetsForm
      form={MY_FORM}
      // or onChange
      onSubmit={(values => {
        console.log('Submitting...', values);
      }}
    />
  );
}
```
