architect | simple yet powerful plugin system for large-scale node | Plugin library

After upgrading to Angular 13 the application no longer works during runtime. From what I've read NODE_DEBUG is Webpack specific and for some reason is not recognized when running the application with an 'ng serve'. I've also recently upgraded to macOS Monterey. I've very stuck at the moment....

package.json

I'm trying to connect my app with a firebase db, but I receive 4 error messages on app.module.ts:

I am creating a banking application. Currently, there is one primary service, the transaction service. This service allows getting transactions by id, and creating transactions. In order to create a transaction, I first want to check if the transaction is valid, by checking the balance of the account it is trying to deduct from, and seeing if they have enough balance. Right now I am doing

TransactionController calls TransactionService. TransactionService creates Transaction, then checks if this is a valid transaction. At this point, I have created an AccountsService, that queries the AccountsRepository, returns an Account. I then do the comparison based on Account.balance > Transaction.amount.

I am conscious here that the TransactionService create method is relying on the AccountService get method. Additionally, AccountService is never directly called from a controller.

Is this an ok way to architect, or is there a more elegant way to do this?

I have upgraded My Angular CLI project from 8 to 9.

Here are the current Angular CLI and other package versions:

I am new to JS. I want to apply filter on array based on other arrays. For example : Filter data array based on property names from colNames and values from Values array. The colNames and Values arrays can have any length (not always 2).

I am new to angular and was following the documentation to build a basic app.

Node - v14.7.3
npm - 7.22.0
Angular CLI: 12.2.4
OS: win32 x64
@angular-devkit/architect 0.1202.4
@angular-devkit/build-angular 12.2.4
@angular-devkit/core 12.2.4
@angular-devkit/schematics 12.2.4
@schematics/angular 12.2.4
rxjs 6.6.7
typescript 4.3.5

So far all I have done is

npm install @angular/cli

followed by ng new firstApp

and ng serve

Following is the error that I am receiving,

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.

I am using Sparx Enterprise Architect and am somehow confused that I did not find any hint on the internet regarding the following question: How can I show the programming language of a component in the component diagram?

It is clear to me that I could use custom stereotypes but this is not a good idea as it prevents me from using "real" stereotypes later on.

After have read Clean Architecture by Uncle Bob i have been thinking about the concept of screaming architecture and the last chapter around organizing code.

I have generally liked working with layers being present in the structure to easily place code in the correct layer but I also see a benefit in dividing by feature.

A large project I recently started working on does not present the layer structure at all and you have to look at an architecture document to see in what layer the java package resides. The project uses OSGI bundles.

This project is worked on successfully by a large amount of developers and seems to work well but I can't help feeling that the structure is confusing and hard to work with and the architect needs to be involved when creating new features to make sure layers are adhered to.

My question is if this is common and what the reason would be to not include the layer structure in some way?

For instance doing something like this seems like a clean solution. https://blog.ttulka.com/package-by-component-with-clean-modules-in-java
