JSON Forms - More Forms. Less Code

Complex Forms in the blink of an eye

JSON Forms eliminates the tedious task of writing fully-featured forms by hand by leveraging the capabilities of JSON, JSON Schema and Javascript.

Vue Vanilla Renderers

This is the JSON Forms Vue Vanilla renderers package which provides a HTML5-based renderer set for JSON Forms Vue.

JSON Forms Vue seed app

See our JSON Forms Vue seed repository to get started as quickly as possible.

Quick start

Install JSON Forms Core, Vue and Vue Vanilla Renderers

npm i --save @jsonforms/core @jsonforms/vue @jsonforms/vue-vanilla

Also add the packages to the transpile dependencies in the vue.config.js file:

module.exports = {
  transpileDependencies: [
    '@jsonforms/core',
    '@jsonforms/vue2',
    '@jsonforms/vue2-vanilla',
  ],
};

Use the json-forms component for each form you want to render and hand over the renderer set.

<script>
import { JsonForms } from '@jsonforms/vue';
import { vanillaRenderers } from '@jsonforms/vue-vanilla';
import { defineComponent } from 'vue';

const renderers = [
  ...vanillaRenderers,
  // here you can add custom renderers
];

export default defineComponent({
  components: {
    JsonForms,
  },
  data() {
    return {
      renderers: Object.freeze(renderers),

      data: {
        number: 5,
      },
      schema: {
        properties: {
          number: {
            type: 'number',
          },
        },
      },
      uischema: {
        type: 'VerticalLayout',
        elements: [
          {
            type: 'Control',
            scope: '#/properties/number',
          },
        ],
      },
    };
  },
  methods: {
    onChange(event) {
      this.data = event.data;
    },
  },
});
</script>
<template>
  <json-forms
    :data="data"
    :schema="schema"
    :uischema="uischema"
    :renderers="renderers"
    @change="onChange"
  />
</template>

By default the Vanilla Renderers don't apply any CSS at all. For a quick start you can use @jsonforms/vue-vanilla/vanilla.css.

For more information on how JSON Forms can be configured, please see the README of @jsonforms/vue.

Styling

Each rendered HTML element specifies a CSS class which can be used to style it. This process can also be customized so that each element declares user-specified CSS classes. Therefore JSON Forms Vue Vanilla can be integrated with any CSS-only UI framework quite easily.

You can find the default CSS classes in `defaultStyles.ts.

To render your own classes simply provide them as styles. These styles replace the defaultStyles. If you want to fall back to defaultStyles or combine them with your own classes you'll need to do so programmatically, e.g.:

<script>
import { JsonForms } from '@jsonforms/vue';
import {
  defaultStyles,
  mergeStyles,
  vanillaRenderers,
} from '@jsonforms/vue-vanilla';
import { defineComponent } from 'vue';

// mergeStyles combines all classes from both styles definitions
const myStyles = mergeStyles(defaultStyles, {
  control: { root: 'my-control' },
});

export default defineComponent({
  name: 'app',
  components: {
    JsonForms,
  },
  data() {
    return {
      renderers: Object.freeze(vanillaRenderers),
      data: {
        number: 5,
      },
      schema: {
        properties: {
          number: {
            type: 'number',
          },
        },
      },
      uischema: {
        type: 'VerticalLayout',
        elements: [
          {
            type: 'Control',
            scope: '#/properties/number',
          },
        ],
      },
    };
  },
  methods: {
    onChange(event) {
      this.data = event.data;
    },
  },
  provide() {
    return {
      styles: myStyles,
    };
  },
});
</script>
<template>
  <json-forms
    :data="data"
    :schema="schema"
    :uischema="uischema"
    :renderers="renderers"
    @change="onChange"
  />
</template>

You can also use specify styles in the ui schema via the options.styles property. Attributes specified here override the respective defaultStyles or provided styles. Attributes not specified here fall back to either the defaultStyles or provided styles.

{
  "type": "Control",
  "scope": "#/properties/name",
  "options": {
    "styles": {
      "control": {
        "root": "my-control-root"
      }
    }
  }
}
