Runtime error with Webpack v5

[benochr]

Environment

• Package version(s): 3.35.0
• Operating System: MacOS Catalina 10.15.7
• Browser name and version: Chrome 86.0.4240.111

Actual behavior

When building with Webpack v5.3.0 we get a runtime error.

classes.js:20 Uncaught ReferenceError: process is not defined
    at Module../node_modules/@blueprintjs/core/lib/esm/common/classes.js (classes.js:20)
    at __webpack_require__ (bootstrap:18)

Webpack 5 no longer includes polyfills for it, as described here

Expected behavior

No runtime errors. Support builds with webpack 5.

I'll update the code to avoid referencing process directly. In the meantime you can work around this with DefinePlugin or EnvironmentPlugin.

This would also fix #3703

In the meantime you can work around this with DefinePlugin or EnvironmentPlugin.

See #3739 (comment) for an example.
