Purpose

The purpose of this library is to create forms for single page applications, with a symfony backend. The forms are constructed in the backend and serialized to json, that can be rendered in the frontend. In the assets folder you can find a react component to render the form. There are 2 versions of the form:

• formV1, is the original react components for rendering the form, kept for backwards compatibility.
• formV2, the new components and the recommended way to render the json.

Usage

Add this to your services.yaml.

services:
    _instanceof:
        PrecisionSoft\Symfony\JsonForm\Service\Contract\AbstractFormService:
            calls:
                - [ setSerializer, [ '@serializer' ] ]

React

Use the components from ./assets/react folder to interpret the backend response. The Config component is project specific. For me, it holds the locale context of the application. It is integrated with:

• willdurand/js-translation-bundle for the Translator.
• friendsofsymfony/jsrouting-bundle for the UrlGenerator.

Dev

git clone git@gitlab.com:precision-soft-open-source/symfony/json-form.git
cd json-form

./dc build && ./dc up -d

Todo

• Render and handle complex types like \DateTime.
• Unit tests.
