I have tried manually adding Polyfills for each issue but the existing libraries are thousands of lines long and have required years to develop. Recreating this functionality from scratch would be an exhaustive effort. As a large share of modern libraries rely on ES6 and its polyfills. This issue greatly limits developer options. Polyfill libraries ES6-Shim and Core. So far in my testing I've got the error down to these 2 polyfills. All of the other Angular requirements will load without issue.

I have tried to step through the code until it finally dies but so far I haven't been able to track it that far. My thoughts at the moment are that this is a collision of type 'Map' which is defined globally in the SP-Loader and in the Core-JS polyfills.

If you console. Hi ArcanDotNet did you find any way to fix this? We're facing the same issue, in IE11 indeed. So I came up with a workaround-ish. I am by no means advocating this as a proper solution, but it does resolve the problem.

SP-Loader defines a global object named 'Map' which is an ES6 standard they are essentially polyfilling. In SPFX v1. After an exhaustive amount of debugging and trying various things I tried logging the value of map, and eventually undefining it in my web part code just before I load the proper core-js polyfill for the same ES6 standard.

By this point in the SP-Loader lifecycle, it seems replacing the existing Map function with the core-js implementation does not break SPFX and the web part will load.

A proper resolution to this issue would be for SPFX to import core-js polyfills for the sp-loader or something of the like. The current Map implementation that's defined in the loader and handed down to the rest of the web part does not meet the specification. ArcanDotNet indeed, the Map object inside es6-shim seemed to be the cause with us.

Thanks for the pointers! The default SP-Loader implementation of the Map object breaks when you use it with other core-js polyfills such as Array. I tried what ArcanDotNet indicated but it did not work. I suppose that the incompatibility in my case comes from another object different from the "Map". Polyfills are global and affect all components on the page.

Although I understand the motivation here, a third-party component really should not be loading polyfills.

Even if it doesn't break today as seen aboveit may break with some future SPFx update or in some other context that wasn't tested e. The sp-polyfills package was designed to be very conservative for performance reasons, since it is guaranteed to be loaded on every page where SPFx runs.These libraries may make use of some features not found in older browsers, mainly fetch, Map, and Proxy.

This primarily affects Internet Explorer 11, which requires that we provide this missing functionality.

Train test split

There are several ways to include this missing functionality. We created a package you can use to include the needed functionality without having to determine what polyfills are required. This package is only needed if you need to support IE Because the latest version of SearchQueryBuilder uses Proxy internally you can fall back on the older version for IE 11 as shown below.

If acceptable to your design and security requirements you can use a service to provide missing functionality. This loads scripts from a service outside of your and our control, so please ensure you understand any associated risks. To use this option you need to wrap the code in a function, here called "stuffisloaded".

Then you need to add another script tag as shown below that will load what you need from the polyfill service. Note the parameter "callback" takes our function name. If you are using a module loader you need to load the following two files as well.

Using Polyfills for IE11 in SharePoint Framework (SPFx) Solutions with PnPjs

You can do this form a CDN or your style library. One issue you still may see is that you get errors that certain libraries are undefined when you try to run your code. This is because your code is running before these libraries are loaded. You need to ensure that all dependencies are loaded before making use of the pnp libraries.
