## Quick Start

First you need a vue application like [Vue Admin Next](https://github.com/openfext/vue-admin-next).

### Install

```bash
npm i element-form-builder
```

### Registration

#### Global Registration

```javascript
import FormBuilder from 'element-form-builder';
import ElFormAdaptor from 'element-form-builder/lib/adaptor/element';

Vue.use(FormBuilder); // form-builder
Vue.use(ElFormAdaptor); // el-form-adaptor
```

#### Local Registration

Use the factory method based on the specified component:

```javascript
import { createFormBuilder } from 'element-form-builder';
import { ElFormAdaptor } from 'element-form-builder/lib/adaptor/element';
import AwesomeFormComponents from 'path/to/awesome/components';

export default {
  name: 'awesome-form'

  components: {
    FormBuilder: createFormBuilder({
      components: {
        ElFormAdaptor,

        ...AwesomeFormComponents
      }
    })
  },
}
```

### Build Form

Vue template:

```html
<el-form>
  <form-builder :form="form" :config="formConfig"></form-builder>
</el-form>
```

Vue component:

```javascript
import { useForm } from '@fext/vue-use';

export default {
  components: {
    FormBuilder: createFormBuilder({
      components: {
        ElFormAdaptor
      }
    })
  },

  setup() {
    const form = useForm();

    return {
      form
    };
  },

  data() {
    return {
      formConfig: [
        {
          component: 'div',
          fields: [
            {
              name: 'comment',
              component: 'ElFormAdaptor',
              label: 'Normal Input',
              rules: {
                required: true
              },
              props: {
                placeholder: 'Render with el-input component'
              }
            }
          ]
        }
      ]
    };
  }
};
```
