Getting Started with Vue using TypeScript and Options API

31 Jul 202415 minutes to read

This article provides a step-by-step guide for setting up a Vite project with a TypeScript environment and integrating the Syncfusion Vue components using the Options API.

The Options API is the traditional way of writing Vue.js components, where the component logic is organized into a series of options that define the component’s properties and behavior. These options include data, methods, computed properties, watchers, lifecycle hooks, and more.

Prerequisites

System requirements for Syncfusion Vue UI components

Set up the Vite project

A recommended approach for beginning with Vue is to scaffold a project using Vite. To create a new Vite project, use one of the commands that are specific to either NPM or Yarn.

npm create vite@latest

or

yarn create vite

Using one of the above commands will lead you to set up additional configurations for the project:

1.Define the project name: We can specify the name of the project directly. Let’s specify the name of the project as my-project for this article.

? Project name: » my-project

2.Select Vue as the framework. It will creates a Vue 3 project.

? Select a framework: » - Use arrow-keys. Return to submit.
  Vanilla
> Vue
  React
  Preact
  Lit
  Svelte
  Others

3.Choose TypeScript as framework variant to build this Vite project using TypeScript and Vue.

? Select a variant: » - Use arrow-keys. Return to submit.
  JavaScript
> TypeScript
  Customize with create-vue ↗
  Nuxt ↗

4.Upon completing the aforementioned steps to create the my-project, run the following command to install its dependencies:

cd my-project
npm install

or

cd my-project
yarn install

Now that my-project is ready to run with default settings, let’s add Syncfusion components to the project.

Add Syncfusion Vue packages

Syncfusion Vue component packages are available at npmjs.com. To use Syncfusion Vue components in the project, install the corresponding npm package.

This article uses the Vue Schedule component as an example. To use the Vue Schedule component in the project, the @syncfusion/ej2-vue-schedule package needs to be installed using the following command:

npm install @syncfusion/ej2-vue-schedule --save

or

yarn add @syncfusion/ej2-vue-schedule

Import Syncfusion CSS styles

You can import themes for the Syncfusion Vue component in various ways, such as using CSS or SASS styles from npm packages, CDN, CRG and Theme Studio. Refer to themes topic to know more about built-in themes and different ways to refer to themes in a Vue project.

In this article, Material theme is applied using CSS styles, which are available in installed packages. The necessary Material CSS styles for the Schedule component and its dependents were imported into the <style> section of src/App.vue file. Vite app generates a default styles.css file which we do not need for this example. Before running the sample, delete the content of src/style.css or remove the file if it’s unused.

To import the necessary CSS styles for the Schedule component, as well as its dependent styles, into the src/App.vue file, you can use the provided code snippet within the <style> section. Let’s import the Material theme for the Schedule component.

<style>
@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-calendars/styles/material.css';
@import '../node_modules/@syncfusion/ej2-dropdowns/styles/material.css';
@import '../node_modules/@syncfusion/ej2-inputs/styles/material.css';
@import '../node_modules/@syncfusion/ej2-navigations/styles/material.css';
@import '../node_modules/@syncfusion/ej2-popups/styles/material.css';
@import '../node_modules/@syncfusion/ej2-vue-schedule/styles/material.css';
</style>

The order of importing CSS styles should be in line with its dependency graph.

Add Syncfusion Vue component

Follow the below steps to add the Vue Schedule component using Options API:

1.First, import the Schedule component in the script section of the src/App.vue file.

<script>
  import { ScheduleComponent as EjsSchedule, ViewsDirective as EViews, ViewDirective as EView, ResourcesDirective as EResources, ResourceDirective as EResource, EventSettingsModel, Day, Week, WorkWeek, Month, Agenda, DragAndDrop, Resize } from "@syncfusion/ej2-vue-schedule";
</script>

2.The next step is to register the Schedule component and its child directives in Vue.

import { ScheduleComponent, ViewsDirective, ViewDirective, ResourcesDirective, ResourceDirective, EventSettingsModel, Day, Week, WorkWeek, Month, Agenda, DragAndDrop, Resize } from "@syncfusion/ej2-vue-schedule";
//Component registration
export default {
  name: "App",
  // Declaring component and its directives
  components: {
    'ejs-schedule': ScheduleComponent,
    'e-views': ViewsDirective,
    'e-view': ViewDirective,
    'e-resources': ResourcesDirective,
    'e-resource': ResourceDirective
  }
}

3.In the template section, define the Schedule component with appointments. To populate the empty Scheduler with appointments, define either the local JSON data or remote data through the dataSource property available within the eventSettings option. Additionally, it is necessary to include the start and end time fields to define any appointments.

<template>
  <div id='app'>
    <ejs-schedule height='550px' width='100%' :selectedDate='selectedDate' :eventSettings='eventSettings'>
      <e-views>
        <e-view option='Day'></e-view>
        <e-view option='Week' startHour='07:00' endHour='15:00'></e-view>
        <e-view option='WorkWeek' startHour='10:00' endHour='18:00'></e-view>
        <e-view option='Month' showWeekend=false></e-view>
        <e-view option='Agenda'></e-view>
      </e-views>
      <e-resources>
        <e-resource field="OwnerId" title="Owner" name="Owners" :dataSource="ownerDataSource" textField="OwnerText"
          idField="Id" colorField="OwnerColor">
        </e-resource>
      </e-resources>
    </ejs-schedule>
  </div>
</template>

4.Declare the values for the dataSource property in the script section.

<script lang="ts">
export default {
  name: "App",
  ...
  data() {
    return {
      ...
      eventSettings: {
        dataSource: [
          {
            Id: 1,
            Subject: 'Surgery - Andrew',
            EventType: 'Confirmed',
            StartTime: new Date(2021, 7, 10, 9, 0),
            EndTime: new Date(2021, 7, 10, 10, 0),
            OwnerId: 2
          },
          {
            Id: 2,
            Subject: 'Consulting - John',
            EventType: 'Confirmed',
            StartTime: new Date(2021, 7, 11, 10, 0),
            EndTime: new Date(2021, 7, 11, 11, 30),
            OwnerId: 3
          },
          {
            Id: 3,
            Subject: 'Therapy - Robert',
            EventType: 'Requested',
            StartTime: new Date(2021, 7, 12, 11, 30),
            EndTime: new Date(2021, 7, 12, 12, 30),
            OwnerId: 1
          }
        ]
      } as EventSettingsModel,
    };
  }
  ...
};
</script>

5.To generate a Schedule with particular views, need to inject the relevant modules into the Schedule. This can be accomplished by utilizing the provide method within the src/App.vue file.

<script lang="ts">
  export default {
    name: "App",
    ...
    provide: {
      schedule: [Day, Week, WorkWeek, Month, Agenda, DragAndDrop, Resize]
    }
  };
</script>

Here is the summarized code for the above steps in the src/App.vue file:

<template>
  <div id='app'>
    <ejs-schedule height='550px' width='100%' :selectedDate='selectedDate' :eventSettings='eventSettings'>
      <e-views>
        <e-view option='Day'></e-view>
        <e-view option='Week' startHour='07:00' endHour='15:00'></e-view>
        <e-view option='WorkWeek' startHour='10:00' endHour='18:00'></e-view>
        <e-view option='Month' showWeekend=false></e-view>
        <e-view option='Agenda'></e-view>
      </e-views>
      <e-resources>
        <e-resource field="OwnerId" title="Owner" name="Owners" :dataSource="ownerDataSource" textField="OwnerText"
          idField="Id" colorField="OwnerColor">
        </e-resource>
      </e-resources>
    </ejs-schedule>
  </div>
</template>

<script lang="ts">
import { ScheduleComponent, ViewsDirective, ViewDirective, ResourcesDirective, ResourceDirective, Day, Week, WorkWeek, Month, Agenda, DragAndDrop, Resize, EventSettingsModel } from "@syncfusion/ej2-vue-schedule";

export default {
  name: "App",
  // Declaring component and its directives
  components: {
    'ejs-schedule': ScheduleComponent,
    'e-views': ViewsDirective,
    'e-view': ViewDirective,
    'e-resources': ResourcesDirective,
    'e-resource': ResourceDirective
  },
  // Bound properties declaration
  data() {
    return {
      selectedDate: new Date(2021, 7, 12) as Date,
      allowMultiple: true as Boolean,
      ownerDataSource: [
        { OwnerText: 'Nancy', Id: 1, OwnerColor: '#ffaa00' },
        { OwnerText: 'Steven', Id: 2, OwnerColor: '#f8a398' },
        { OwnerText: 'Michael', Id: 3, OwnerColor: '#7499e1' }] as Record<string, any>[],
      eventSettings: {
        dataSource: [
          {
            Id: 1,
            Subject: 'Surgery - Andrew',
            EventType: 'Confirmed',
            StartTime: new Date(2021, 7, 10, 9, 0),
            EndTime: new Date(2021, 7, 10, 10, 0),
            OwnerId: 2
          },
          {
            Id: 2,
            Subject: 'Consulting - John',
            EventType: 'Confirmed',
            StartTime: new Date(2021, 7, 11, 10, 0),
            EndTime: new Date(2021, 7, 11, 11, 30),
            OwnerId: 3
          },
          {
            Id: 3,
            Subject: 'Therapy - Robert',
            EventType: 'Requested',
            StartTime: new Date(2021, 7, 12, 11, 30),
            EndTime: new Date(2021, 7, 12, 12, 30),
            OwnerId: 1
          }
        ]
      } as EventSettingsModel,
    };
  },
  provide: {
    schedule: [Day, Week, WorkWeek, Month, Agenda, DragAndDrop, Resize]
  }
};
</script>
