            Make touch and wheel event listeners added by libraries as "passive"
            Asked 2022-Jan-08 at 14:00

            I have two projects:

            1. Bootstrap with jQuery
            2. materialize-css with Vanilla JS

            When running a Lighthouse audit on both projects I used to get this warning caused by materialize-css on one project and jQuery on the other project:

            I say "used to get", because I did manage to fix it for jQuery simply just applying this workaround:

            ...

            ANSWER

            Answered 2022-Jan-08 at 14:00

            First of all, this is just a warning, not an error.

            Is there a way, similar to jQuery workaround above, to fix all the materialize-css added event listeners? P.S. It does not use jQuery

            Yes, there are, actually, three ways:

            1. Get read of the warning, without improving performance

            Simply add { passive: false } as third param to all listeners which don't have an object as third parameter. This will tell browsers that .preventDefault() might be called on those events. However, especially on scroll, touchmove and touchstart events, the performance increase is considerable when the browser knows that the default behavior won't be prevented on an event. When marked as passive, the scrolling will be much smoother and the perceived performance will be significantly increased.

            1. Improve performance by potentially breaking functionality

            Add { passive: true } as third param to all listeners which don't have an object as third paramter. This will tell browsers that .preventDefault() will never be called on those events. You'll see a performance increase, but code relying on preventing those events will break.

            Note: this is what both the jQuery fix and the default-passive-events package do, btw.

            1. The proper way

            The proper way is to go into the source code of whatever lib you're fixing, figure out which events might ever be prevented and add { passive: false } for those, while adding { passive: true } for everything else.
            I'd argue finding all the places where an event is prevented in a lib is not a huge task.
            You can do this in a fork, ideally PR-ing it back into the lib's repo, for others to benefit, just like you benefit from the lib itself.

            Here's solution 1.

            Firebase - Use of undeclared identifier 'FIRAnalyticsConfiguration'

            I'm trying to compile an Ionic 3 app with Firebase on Ios using Xcode Version 12.3 (12C33).

            Even with the module in the Podfile, for some reason it keeps giving 'Use of undeclared identifier 'FIRAnalyticsConfiguration'

            What I'm doing wrong? Everything looks updated.

            According to release notes of Firebase Analytics FIRAnalyticsConfiguration APIs was removed in version 6.0.0. You can use the same APIs directly on FirebaseAnalytics class.
