Web Snippet for the Application Insights Javascript SDK

This project exists to publish latest Application Insights Javascript Web Snippet.

## Basic Usage

Add the Application Insights Web Snippet to your app's dependencies and package.json.
```
npm i @microsoft/applicationinsights-web-snippet
```

### Pass in Key via Function (available since v1.1.0)
Import the helper function from the package to easily get the snippet
```
import { getSdkLoaderScript } from "@microsoft/applicationinsights-web-snippet";
```

Configure the snippet with your connectionString or other customerized field:
```
let config = {connectionString: "InstrumentationKey=xxx", name: "myAppInsights"}; 
// or let config = {instrumentationKey: key, sri: true};
let theSnippet = getSdkLoaderScript(config);
```

### Multiple Snippet Run Simutinously (available since v1.2.0)
Configure two snippets with different name.
```
let firstConfig = {connectionString: "InstrumentationKey=xxx", name: "firstAppInsights"}; 
let firstSnippet = getSdkLoaderScript(firstConfig);
let secondConfig = {connectionString: "InstrumentationKey=xxx", name: "secondAppInsights"}; 
let secondSnippet = getSdkLoaderScript(secondConfig);
```

### Snippet Run With Integrity Check and Minified Loading Time (available since v1.2.0)
Configure the snippet with sri enabled.
```
let config = {connectionString: "InstrumentationKey=xxx", sri: true};
```
