IE compatibility about systemjs

[guybedford]

The code is all written to work with IE8, but it hasn't been properly
tested. I'm happy to work with you on the support if you need.

Hi, This is what happened when I tried to test the SystemJS on IE8

Let me know if you have ideas on where the problem is and how I can fix. Thanks

[guybedford]

Thanks for looking into this. I believe this is because import is a reserved property in IE8. I've added a fix to both es6-module-loader (ModuleLoader/es-module-loader@d1a684d) and SystemJS (f44df33) on the master branches. Let me know if this helps.

One other thing - loading ES6 modules in IE8 is not supported as the Traceur runtime is ES5 compatible only. I can work with you on a suitable build workflow here to make ES6 modules work in IE8 though (say compiling into AMD). For now, it is probably best to test SystemJS just loading AMD modules.

We've just created two new IE compatibility fixes - ModuleLoader/es-module-loader@932e4aa

(in case you already tried it).

Thanks for your hard work on this. I am happy to help you working and have a look on existing issues in IE8. In the meantime, please see the following error message I got from my colleagues in testing in IE8. Any suggestion to fix will be warmly welcomed!

I've resolved this in the latest master branch. Thanks for reporting back!

Hi, Could you please suggest on what version of system.js that has the best compatibility so far, especially with IE browser. Because I found there are multiple versions under the dist/ folder and therefore not sure which one should I use for a stable release.

Many thanks for advice!

[guybedford]

Sure, I'm working on some browser testing - will keep you informed.

To update on this - I've been working on IE8 compatibility for the ES6 Module Loader today, and unfortunately have reached a point where the bugs go pretty deep.

The tests are running, and some are passing, but there are IE8 bugs in the promises implementation and normalization functions.

It may be possible to resolve these, but I do not have the time now. IE9 compatibility is the best we can offer until these bugs are resolved.

[guybedford]

IE8 support is finally complete for loading AMD, CommonJS and global scripts on the master versions of SystemJS and ES6 Module Loader. Transpiled ES6 may be supported in future.

I will be documenting the support and limitations, making a release shortly.

[guybedford]

This is now in the latest release.

[simonykq]

Great.

Many thanks for your update and hard work on this. I will try and use this into our existing projects
