IE10 does not support setting the __proto__ property of objects as an
alternative to Object.setPrototypeOf. Because Babel generates code that
uses the @babel/runtime/helpers/inheritsLoose helper, and that helper
relies on setting __proto__, subclassing fails in Babel-generated code in
IE10 (and earlier), which causes a white screen of death in newly created
Meteor apps.
This commit checks whether setting __proto__ works, and (if not) overrides
the inheritsLoose helper with an implementation that does not rely on
setting __proto__. This logic applies only in legacy browsers, thanks to
api.addFiles("legacy.js", "legacy").
Although this shim isn't perfect (for example, there is no way to set up
true inheritance of static properties), it will allow inheritance to work
in browsers that would otherwise be completely broken.
Since IE10 represents only 0.1% of the world market, we should not
overinvest in keeping it working, but this seemed like a good opportunity
to take advantage of legacy bundling, without adding any new code to the
modern bundle.
Meteor is an ultra-simple environment for building modern web applications.
With Meteor you write apps:
- in modern JavaScript
- that send data over the wire, rather than HTML
- using your choice of popular open-source libraries
