# 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](https://github.com/Azure/azure-sdk-for-js/blob/main/documentation/Bundling.md) 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:

```js
import {main} from "../exampleBrowser"

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

Then run: `npm run webpack`
