JavaScript/jQuery Sankey - Web API Service

DevExtreme provides the DevExtreme.AspNet.Data extension to access an ASP.NET Web API service. This extension consists of two parts: the server-side part implements data processing on the server according to the DevExtreme UI components' protocol; the client-side part creates and configures a CustomStore to access the server from the client. The following code shows how to use the extension's client-side createStore method:

$(function() {
    const serviceUrl = "https://url/to/my/service";

    $("#sankeyContainer").dxSankey({
        dataSource: DevExpress.data.AspNet.createStore({
            key: ['from', 'to'],
            loadUrl: serviceUrl + "/GetAction"
        }),
        // ...
    });
});

<dx-sankey [dataSource]="store">
    <!-- ... -->
</dx-sankey>

import { Component } from '@angular/core';
import CustomStore from 'devextreme/data/custom_store';
import { createStore } from "devextreme-aspnet-data-nojquery";

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent {
    store: CustomStore;
    constructor() {
        const serviceUrl = "https://url/to/my/service";
        this.store = createStore({
            key: ['from', 'to'],
            loadUrl: serviceUrl + "/GetAction"
        });
    }
}

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

import { DxSankeyModule } from 'devextreme-angular';

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        DxSankeyModule
    ],
    providers: [ ],
    bootstrap: [AppComponent]
})
export class AppModule { }

<template>
    <DxSankey :data-source="store">
        <!-- ... -->
    </DxSankey>
</template>

<script>
import DxSankey from 'devextreme-vue/sankey';
import { createStore } from "devextreme-aspnet-data-nojquery";

const serviceUrl = "https://url/to/my/service";

const store = createStore({
    key: ['from', 'to'],
    loadUrl: serviceUrl + "/GetAction"
});

export default {
    components: {
        DxSankey
    },
    data() {
        return {
            store
        }
    }
}
</script>

import Sankey from 'devextreme-react/sankey';
import { createStore } from "devextreme-aspnet-data-nojquery";

const serviceUrl = "https://url/to/my/service";

const store = createStore({
    key: ['from', 'to'],
    loadUrl: serviceUrl + "/GetAction"
});

export default function App() {
    return (
        <Sankey dataSource={store}>
            {/* ... */}
        </Sankey>
    );
}

A 1-Click Solution for CRUD Web API Services with Role-based Access Control via EF Core

If you target .NET for your backend API, be sure to check out Web API Service and register your free copy today. The Solution Wizard scaffolds an OData v4 Web API Service (.NET 6+) with integrated authorization & CRUD operations powered by EF Core ORM. You can use OAuth2, JWT or custom authentication strategies alongside tools like Postman or Swagger (OpenAPI) for API testing. The built-in Web API Service also filters out secured server data based on permissions granted to users. Advanced/enterprise functions include audit trail, endpoints to download reports, file attachments, check validation, obtain localized captions, etc.

To use the free Solution Wizard (which creates the Web API Service), run the Universal Component Installer from the DevExpress Download Manager and use our predefined template in Visual Studio 2022+.
