Angular & native crypto module
Author: qortexCreated Feb 12, 2020Updated May 18, 2026
I understand the move to 4.0.0 uses native crypto module.
As a result, with my Angular app, I get the error message below when building.
As I understand, the crypto module needs to be explicitly bundled by Webpack as it's not by default with Angular config.
Does anyone already know how to do that? I'm not that familiar with Webpack and would appreciate any hint.
