Breaking Tech News: ASP.NET Core Integrates HTMX and Chart.js for Enhanced Web Development

Saturday, April 13, 2024

In a move set to revolutionize web development capabilities, the latest update to ASP.NET Core introduces seamless integration with HTMX and Chart.js. This dynamic combination promises to empower developers with unprecedented flexibility and interactivity in crafting modern web applications.

ASP.NET Core, renowned for its robustness and versatility in building web applications, now pairs effortlessly with HTMX, a lightweight JavaScript library for AJAX-driven web pages. HTMX simplifies AJAX interactions by leveraging HTML attributes, allowing developers to enhance user experience without diving deep into complex JavaScript code.

Moreover, the integration includes Chart.js, a popular open-source library for creating dynamic and visually appealing charts and graphs. With Chart.js, developers can effortlessly visualize data, trends, and insights within their ASP.NET Core applications, adding a layer of sophistication and clarity to their projects.

This integration opens up a plethora of possibilities for developers, enabling them to create responsive and feature-rich web applications with minimal effort. By combining the power of ASP.NET Core's server-side capabilities with the interactivity of HTMX and the visualization prowess of Chart.js, developers can now deliver immersive user experiences like never before.

"We're thrilled to introduce this integration, which empowers developers to build cutting-edge web applications with ease," said a spokesperson from the ASP.NET Core development team. "By bringing together ASP.NET Core, HTMX, and Chart.js, we're providing developers with a comprehensive toolkit to create modern, data-driven web experiences that exceed user expectations."

The community response to this announcement has been overwhelmingly positive, with developers expressing excitement about the potential for innovation and creativity that this integration unlocks. Many anticipate leveraging these technologies to streamline development workflows and deliver more engaging web applications to end-users.

With ASP.NET Core's commitment to continuous improvement and innovation, this integration marks another milestone in its journey to remain at the forefront of web development frameworks. Developers are encouraged to explore the possibilities offered by ASP.NET Core, HTMX, and Chart.js to elevate their web development projects to new heights of excellence.

First, let's create a simple ASP.NET Core controller to provide data to the frontend:

using Microsoft.AspNetCore.Mvc;

namespace YourNamespace.Controllers
    public class DataController : ControllerBase
        public IActionResult GetChartData()
            // Dummy data for demonstration purposes
            var data = new int[] { 10, 20, 30, 40, 50 };


            return Ok(data);

Next, let's create a Razor view to display the chart and fetch data using HTMX:

@model YourNamespace.Pages.IndexModel
    ViewData["Title"] = "Chart Page";

    <canvas id="chartCanvas" width="400" height="200"></canvas>

@section Scripts {
    <script src=""></script>
    <script src=""></script>
        async function fetchDataAndRenderChart() {
            try {
                const response = await fetch('/api/Data/GetChartData');
                const data = await response.json();

                const ctx = document.getElementById('chartCanvas').getContext('2d');
                new Chart(ctx, {
                    type: 'bar',
                    data: {
                        labels: ['Label 1', 'Label 2', 'Label 3', 'Label 4', 'Label 5'],
                        datasets: [{
                            label: 'Sample Data',
                            data: data,
                            backgroundColor: 'rgba(54, 162, 235, 0.2)',
                            borderColor: 'rgba(54, 162, 235, 1)',
                            borderWidth: 1
                    options: {
                        scales: {
                            yAxes: [{
                                ticks: {
                                    beginAtZero: true
            } catch (error) {
                console.error('Error fetching data:', error);

        document.addEventListener('DOMContentLoaded', () => {

In this example, we have a controller DataController with a single action GetChartData that returns dummy data. The Razor view Index.cshtml fetches this data using HTMX when the page loads and then uses Chart.js to render a bar chart based on the fetched data.

Make sure to adjust namespaces, routes, and data fetching logic as per your application's requirements.
