Microsoft Application Insights JavaScript SDK - Shims

Shims for the Application Insights Javascript SDK

This project exists to break the dependency on the version of tslib that is used during the build and deploy, this is mostly due to several breaking changes that have reduced our ability to publish fixes.

While the Application Insights JS SDK will use the stubs defined in this packaging for the browser instances (those that are uploaded to the CDN) they are built using the polyfill pattern, so if a global implementation of __extends() and __assign() already exist those versions will be used.

ES3 Support removed from v3.x

ES3 support has been removed from the latest version (v3.x) which is also consumed by ApplicationInsights v3.x, if required see for ES3/IE8 Support and you will need to remain on v2.x versions

Global __extends() and __assign() changes - v2.0.0 or greater

From v2.0.0 or greater the globally defined __extends() and __assign() methods are no longer exposed as global by default.

If you need to expose the TsLib helpers globally (which occurred by default for v1.x.x) you now will need to import and call the __exposeGlobalTsLib() function.

import { __exposeGlobalTsLib } from "@microsoft/applicationinsights-shims";

__exposeGlobalTsLib();

Build:

npm install -g grunt-cli
npm install
npm run build --silent

Run unit tests:

npm run test
