Angular Directives by Scalyr ---. This is the source code for the optimization directives Scalyr created to improve the responsiveness of its user interface, as discussed in the blog post [Optimizing AngularJS: 1200ms to 35ms] These directives are meant to demonstrate the optimization techniques discussed in the blog post. The directives were really only meant for internal use, but since there was sufficient interest from readers, we are publishing the source. Unfortunately, we cannot make maintaining this library a high priority. We will push bug fixes and accept pull requests from other developers, but beyond that, the source is provided as is. We expect this source will act more as a starting point for other developers rather than as a complete standalone Javascript library. Also note, because some of the optimization techniques rely on non-public AngularJS variables and methods, these directives may not work for all versions of AngularJS. The current tests validate them against 1.2.1. Furthermore, the directives were built with particular use cases in mind so they may not have all of the features you would expect. For example, our repeat directive 'slyRepeat' does not support animations and other features that 'ngRepeat' does.

QUESTION
I am trying to implement Firebase Realtime Database into a angular project and Im getting stuck at one of the very first steps. Importing AngularFireModule and AngularFireDatabaseModule. It gives me the following error:
...ANSWER
Answered 2021-Aug-26 at 13:20AngularFire 7.0.0 was launched yesterday with a new API that has a lot of bundle size reduction benefits.
Instead of top level classes like AngularFireDatabase, you can now import smaller independent functions.
QUESTION
I recently upgraded all of my dependencies in package.json to the latest. I went from Angular 12.2.0 to 13.0.1 and github is now rejecting my push with the following file size error. Is there some setting I need to define in angular.json build profile that will help minimize these cache file sizes?
...ANSWER
Answered 2021-Nov-24 at 16:53Make sure your .gitignore is in the parent folder of .angular.
In that .gitignore file, a simple .angular/cache/ should be enough to ignore that subfolder content.

QUESTION
Recently I was having a problem installing an npm package (that used node-gyp). I tried upgrading the minor version of node from version 16.13.0 to 16.13.1 and upgrading my angular cli from 13.0.2 to 13.2.0. Once I got the package to install I generated a library with ng g library new-library. I don't know what what actually broke it, but now whenever I try to build alibrary it produces an error. I try ng build my-lib and get the below error.

Apparently throwError(error) is now deprecated. The IntelliSense of VS Code suggests throwError(() => new Error('error'). new Error(...) accepts only strings. What's the correct way to replace it without breaking my HttpErrorHandlerService ?

I just upgraded an environment with nrwl from angular version 11 to 12 with two angular applications and several libraries. After update when I try to compile using optimization settings:
angular.json
...ANSWER
Answered 2022-Jan-31 at 19:50Reason of the issue
It is expected browserslist to return an entry for each version ("safari 15.2", "safari 15.3") instead of a range ("safari 15.2-15.3"). So, this is just a bug in the parsing logic of Safari browser versions which needs to be corrected and will be done soon in fixed versions of Angular 12/Angular 13. Link to details is here.
IMPORTANT UPDATE:
This is fixed in v12.2.16 and v13.2.1, please update if you are experiencing this issue. Users on v11 shouldn't be affected. Link to details is here. If you can not/do not want to update for any reason, then one of the workarounds below can be used.
Workarounds:
Modify .browserslistrc
Add to .browserslistrc such lines:
QUESTION
I am facing an issue while upgrading my project from angular 8.2.1 to angular 13 version.
After a successful upgrade while preparing a build it is giving me the following error.

QUESTION
According to the docs, there's nothing called .angular being regarded. Yet, in my project, I get that directory, immediately in the root of the project (on the same level as e.g. package.json).
It wasn't there before because my .gitignore would've barked at it. Currently, I'm trying out the latest Angular version, 13.0 and I conclude that it's a new addition to the tooling. Probably, it's some temporary stuff, since its contents are the following.
- .angular/cache/angular-webpack
- .angular/cache/babel-webpack
It was pointless to google .angular directory dot what is and the only (semi-)relevant hit I got was the docs linked above.
What's up with .angular directory and do I need to care (and/or version control it)?
...ANSWER
Answered 2021-Dec-02 at 10:07".angular/cache" folder should be ignored by your version control system (git, svn etc...)
Example for git, add this line to .gitignore file
