angularzonejs

should I care about "Zone.js does not support native async/await in ES2017."?

After upgrading from Angular 9 to 10 I get these warnings when I run ng serve:

WARNING: Zone.js does not support native async/await in ES2017.
These blocks are not intercepted by zone.js and will not triggering change detection.
See: https://github.com/angular/zone.js/pull/1140 for more information.

(node:56581) ExperimentalWarning: The fs.promises API is experimental

Anybody know what this means and if it is something I should care about?

Solution

  • I agree with Andrei. It might not update your component, especially if you're getting the data from an API somewhere. To solve this, you could change the target in your tsconfig.base.json file back to es2015.
