The JS Viewer is a Javascript component that you can easily customize and use in web applications to preview all types of reports - page, rdl, and section reports. The JS Viewer works on modern web application frameworks - ASP.NET MVC, ASP.NET Core MVC, HTML5, and major JavaScript Frameworks such as Angular and Vue.js.
A responsive visualization allows the JS Viewer to automatically adjust to the screen size, so you can use it on all desktop, mobile and touch devices and modern browsers.
