Bundling Azure SDK libraries for a browser

To use Azure SDK libraries on a website, you need to convert your code to work inside the browser. You do this using a tool called a bundler. This process takes JavaScript code written using Node.js conventions and converts it into a format that is understood by browsers. Read here for more info and examples.

Browser sample

The code is browser-compatible, with the main differences being that ingestFromFile accepts a Blob object and ingestFromStream accepts an ArrayBuffer.
The only authentication methods available are user prompt and token provider.

Fallback version of files used in the browser, are called '*.browser.ts'.

To run a quick sample for azure-kusto-ingest we provided a webpack config which uses the file index.html which runs index.js as a script. First add to index.ts:

import {main} from "../exampleBrowser"

main().catch((e) => console.log(e));

Then run: npm run webpack
