Loading the SciChart.js Wasm from CDN

We have added a new API to SciChart.js to allow you to specify where to load the WebAssembly (wasm) file from. Currently, this must be in the local directory on your server or deployed via WebPack as shown in our tutorial #1 – Setting up a SciChart.js project with WebPack.

With SciChart.js 1.3.1514 or above you can specify the URL of the WebAssembly file. We publish SciChart.js to npm but also to a global CDN. Use this syntax to specify loading the wasm file from URL. Be sure to set the version number to match the scichart.js version number if you use our CDN!

// Load the SciChart.js WebAssembly (Wasm) File from a specific URL
// Example below is for cdn.jsdeliver which we publish to 
SciChart.SciChartSurface.configure({
    dataUrl: "https://cdn.jsdelivr.net/npm/[email protected]/_wasm/scichart2d.data",
    wasmUrl: "https://cdn.jsdelivr.net/npm/[email protected]/_wasm/scichart2d.wasm"
});
