DevExtreme Vue UI and Visualization Components

Build Status NPM

This project allows you to use DevExtreme Vue Components.

Getting Started

You can try this live example, feature-based examples or configure local development environment as described below.

Prerequisites

Node.js and npm are required

Install DevExtreme

Install the devextreme and devextreme-vue npm packages:

npm install --save devextreme devextreme-vue

Additional Configuration

The further configuration steps depend on which build tool, bundler or module loader you are using:

Import DevExtreme Modules and Themes

Import DevExtreme modules in a DevExtreme component's file.

import DxButton from 'devextreme-vue/button';

DevExtreme themes can be imported only once in your application's main file:

import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.compact.css';

See the Predefined Themes guide for more information on DevExtreme themes.

Use DevExtreme Components

You can use DevExtreme components in a single file component,

<template>
    <dx-button :text='text'/>
</template>

<script>
import DxButton from 'devextreme-vue/button';
export default {
  name: 'HelloWorld',
  data() {
    return {
      text: 'Hello!'
    };
  },
  components: {
    DxButton
  }
};
</script>

... in a jsx render function,

import Vue from 'vue';
import { DxButton } from 'devextreme-vue';


new Vue({
  el: '#app',
  data: function() {
    return {
      text: "Hello!"
    }
  },
  render: function(h) {
    return (
      <DxButton text={this.text} />
    )
  }
});

... or directly in a vue template.

new Vue({
  el: '#app',
  components: { DxButton },
  template: '<dx-button :text="text" />',
  data() {
    return {
      text: 'Hello!'
    };
  }
});

API Reference

The complete list of components and their APIs are described in the DevExtreme API Reference.

Component Configuration

Set Component Option

  • A constant string value (for example, the Button text):
<dx-button text="Simple button" />
  • A constant non-string value (for example, the CheckBox value):
<dx-check-box :value="true" />
  • A value from a component data:
<dx-button :text="text" />

where : is a shorthand for v-bind directive.

Two-way Binding

Use the sync modifier to bind a bindingProperty to a widget option:

<dx-text-box :value.sync="bindingProperty" />

Editors Value Binding

The DevExtreme Vue editors also support v-model directive that creates two-way binding on the editor's value (for example, TextBox value):

<dx-text-box v-model="text" />

Custom Templates

You can customize widget elements' appearance via the corresponding template properties.

To specify a DevExtreme Vue Component template's markup, use a named slot. You should also specify a slot scope to access the template element's data.

For instance, you can specify the itemTemplate:

<div id="app">
    <dx-list :items="items">
        <div slot="item" slot-scope="data">
            <i>This is my template for {{data}}</i>
        </div>
    </dx-list>
</div>
import Vue from 'vue';
import DxList from 'devextreme-vue/list';

new Vue({
  el: '#app',
  components: { DxList },
  data() {
    return {
      items: [1, 2, 3, 4]
    };
  }
});

item is the default name of the dxList widget's item template. You can specify a custom name for the template and for your slot:

<div id="app">
    <dx-list :items="items" item-template="my-template">
        <div slot="my-template" slot-scope="data">
            <i>This is my template for {{data}}</i>
        </div>
    </dx-list>
</div>

Components with Transcluded Content

The following widgets support putting a content directly to the widget's container:

For example, you can specify the ScrollView widget's content as follows:

<dx-scroll-view>
    <div>Some scrollable content</div>
</dx-scroll-view>

Event Handling

You can subscribe to DevExtreme Component events using the Vue's v-on directive (or @ shorthand)

<dx-text-box v-model="text" @focusIn="handleFocusIn" />
data: function() {
  return {
    text: "text",
    handleFocusIn: () => {
      this.text = 'focused!';
    }
  };
}

You can find the full list of component events in each DevExtreme widget API Reference's Events section (for example, TextBox events).

Getting a Widget Instance

A widget instance is required to call methods. Pass a component key to the $refs property property to get a component whose instance field stores the widget instance. The component's key is defined in the component's ref attribute.

<template>
    <div title="Accessing Widget Instance">
        <dx-text-box :ref="textBoxRefName"/>
        <br/>
        <dx-button text="Set focus" @click="setFocus"/>
    </div>
</template>

<script>
import { DxButton, DxTextBox } from "devextreme-vue";

const textBoxRefName = "some-ref-name";

export default {
  data: function() {
    return {
      textBoxRefName
    };
  },

  components: {
    DxTextBox,
    DxButton
  },

  methods: {
    setFocus: function() {
      this.textBox.focus();
    }
  },

  computed: {
    textBox: function() {
      return this.$refs[textBoxRefName].instance;
    }
  }
};
</script>

Type Checks and TypeScript Support

You should specify proper values for the components' properties because DevExtreme Vue components use Prop Validation and Type Checks. Otherwise, Vue produces a console warning (if you are using the development build).

We also provide TypeScript declarations for DevExtreme Components. Strict typing allows you to catch many bugs and improve your workflow by adding features like auto-completion and automated refactoring.

This example demonstrates how to use DevExtreme Vue components with TypeScript.

DevExtreme Data Layer and Utils

The DevExtreme includes a Data Layer and Utils that can be helpful in different scenarios.

DevExtreme Validation

DevExtreme Vue editors support built-in data validation.

<dx-validation-group>
  <dx-text-box value="email@mail.com">
    <dx-validator :validationRules="validationRules.email" />
  </dx-text-box>
  <dx-text-box value="password">
    <dx-validator :validationRules="validationRules.password" />
  </dx-text-box>
  <dx-validation-summary />
  <dx-button text="Submit" @click="validate"/>
</dx-validation-group>
import { DxButton, DxTextBox, DxValidator, DxValidationGroup, DxValidationSummary } from "devextreme-vue";

export default {
  components: {
    DxButton,
    DxTextBox, 
    DxValidator,
    DxValidationGroup,
    DxValidationSummary
  },
  methods: {
    validate(params) {
      const result = params.validationGroup.validate();
      if (result.isValid) {
          // form data is valid
          //params.validationGroup.reset();
      }
    }
  },
  data: function() {
    return {
      validationRules: {
        email: [
            { type: "required", message: "Email is required." },
            { type: "email", message: "Email is invalid." }
        ],
        password: [
            { type: "required", message: "Password is required." }
        ]
    }};
  }
};

Configuration Components

DevExtreme Vue Components provide configuration components for the underlying widget's complex nested options.

Use a named import to get a configuration component.

import DxChart, { DxTooltip } from "devextreme-vue/chart"; 

You can use all data-bind features (such as .sync modifier) in your nested configuration components.

Basic Usage

The following example demonstrates how to configure the dxChart widget's tooltip option:

<dx-chart
  :data-source="dataSource"
  title="Pizza Shop Complaints">
  <dx-tooltip :enabled="showTooltip"/>
</dx-chart>

<dx-button text="Toggle tooltip" @click="toggleTooltip"/>
import DxChart, { DxTooltip } from "devextreme-vue/chart"; 
import DxButton from "devextreme-vue/button"; 

import { complaintsData } from './data.js';

export default {
  components: {
    DxChart,
    DxTooltip,
    DxButton
  },
  data() {
    return {
      dataSource: complaintsData,
      showTooltip: false
    };
  },
  methods: {
    toggleTooltip() {
      this.showTooltip = !this.showTooltip;
    }
  }
};

Collection Options

You can also use configuration components for complex collection options. The following example demonstrates how to configure the dxDataGrid widget's columns option:

<dx-data-grid :data-source="dataSource">
  <dx-column data-field="firstName"/>
  <dx-column data-field="lastName" caption="Last Name" :visible.sync="showLastName"/>
</dx-data-grid>

<dx-check-box text="Show the 'Last Name' column" v-model="showLastName"/>
import DxDataGrid, { DxColumn } from "devextreme-vue/data-grid"; 
import DxCheckBox from "devextreme-vue/check-box"; 

import { data } from './data.js';

export default {
  components: {
    DxDataGrid,
    DxColumn,
    DxCheckBox
  },
  data() {
    return {
      dataSource: data,
      showLastName: true
    };
  }
};

Note that configuration components are not provided for options that accept a type that depends on another option's value. For example, the DataGrid's editorOptions, Form's editorOptions, Toolbar's widget options.
