QUESTION
I'm trying to execute the following tutorial to integrate an Angular 12 application with Keycloak: Keycloak Integration with Angular Frontend (I've checked other similar tutorials and the instructions are the same).
As described in the article, I've inserted the following lines in src\environments\environment.ts:

QUESTION
I'm looking for advice on how to build artifacts that are composed of combinations of multiple modules without repeating a lot of boilerplate for all possibilities:
We have a software that is deployed as a .war into Tomcat and as an .amp into Alfresco running on the same Tomcat instance.
Everything related to Alfresco / .amp does not matter for the scope of the question. For simplicity just assume a single .war artifact in regards to Maven.
We use the open-core model and have a free version that consists of some code that ends up in an .amp and a .war file that contains the Angular-Frontend and several backend libraries.
We have at the moment two plugins in our software - each plugin provides an additional .amp file and adds a .jar / config files to the .war and we have lot's of extensions - each extensions overwrites/extends some Angular-Frontend files and also adds XML-configuration to the .war and/or .amp
Now I'm trying to migrate to Maven from an ancient ant-based build setup that basically just copies the plugins/extensions on deploy time over the base-install.
I need to be able to create configurations like: core + plugin-a + extension-b or core + plugin-a + plugin-b + extension-c - so that I have several .amp artifacts and a single .war artifact for each configuration.
It would be nice if it's also possible to aggregate extensions like core + plugin-a + plugin-b + extension-c + extension-d
At the moment I'm using the maven assembly plugin for the .war and the maven-frontend-plugin for angular and the assembly-plugin just copies the compiled artifacts into the war.
The .war itself is a maven module.
I could go on with this strategy and create modules for every extensions and every plugin but then I will need a module for every possible combination of the extensions and plugins.
To make it worse some extensions/plugins are commercial and live in different repositories - so I can't just add everything to the open-core POM.
I've looked into profiles but I'm not sure if that would solve my problem - as I need something like a central registry for all the submodules?
Somethink like mvn clean package -Pextension-a,extension-b,plugin-a that creates the artifacts would be great.
How to tackle this problem with Maven? Are there projects with these requirements where I can look how it's solved there?
...ANSWER
Answered 2020-Aug-03 at 12:51This answer is bit speculative, as I do not know anything about Alfresco.
Have you thought about writing a Maven plugin that downloads an extension/plugin (maybe as zip file from your repository?), unpacks it and applies it to your project?
Then you could call the maven plugin with different lists of extensions/plugins.
QUESTION
We are relatively new to Camunda and working on a project at the moment that is giving us a few headaches.
We’ve got a SpringBoot-application with an Angular-Frontend that is supposed to take the data to start a process and send them to our Camunda-engine via REST-API. Aside from regular Strings and integer values we also need files (mainly PDF and Word), which are base64-encoded in the Angular-Frontend and can therefore become a bit larger.
The problem is, the variables (including the files) are encoded into JSON and when the size of the JSON surpasses 64 KB, we get an “Unexpected end-of-input in VALUE_STRING”-exception. Our application is encrypted via SSL (openSSL, created the certificate ourselfs via certbot and added configuration to application.yaml), if that should make any difference.
A few bullet-points also relevant:
- Locally (running Windows 10 or in a VM on CentOS) it is working with no problems
- When trying to start the process via the Camunda Tasklist it also only works if there are no files larger than 64kb attached, without the files the process is starting just fine
- There server where the problem appears is a VM from Strato running Ubuntu, using openJDK 13.0.1 and a PostgreSQL-database
- Usucally we are also connected to our AzureAD (thats why we needed SSL), but switched this off for testing, so this should not be the issue. Mentioning it just in case
Did anybody ever encounter something like that?
Here’s the uppermost part of the exception in question:

Answered 2020-Aug-19 at 07:19Wladmir's comment is correct. You should not store huge amounts of data in the audit trail of a workflow engine and not use it as a system of records. Instead have a service which owns the data and only carry a reference / primary key for the data object in a process variable (reasons include separation of concerns, performance, maintainability, accessibility from other clients, data privacy, encryption,....).
However, if you do store JSON in a process variable, do not store it a as a String but as an object and tell Camunda how it is de/serialized (SerializationDataFormat).
This example shows you how this is done using the JAVA API:

QUESTION
I am attempting to access a secure .net core 3.1 Web API via an Angular 9 front-end. I used the Angular 9 code sample from the MSAL Angular repo.
I can successfully sign in using my own Azure AD App Registrations, but when calling my endpoint (decorated with [Authorize]), I get a 401 in my frontend, as well as in postman (expected).
My Angular Interceptor doesn't even add the bearer token in the request to the API because the getScopesForEndpoint() returns null for the request:
...ANSWER
Answered 2020-Mar-26 at 08:15In your front-end AD app, you need to add the Delegated permission instead of Application permission.
If you have not define a Delegated permission for your Web API App, navigate to it in the portal -> Expose an API -> Add a scope, follow this link to expose an API Delegated permission.
Then in your front-end AD app, add the delegated permission.
After add the permission, click the Grant admin consent for xxx button, it means the admin consent for the permission for the user just in your AAD tenant.
Note: if your app is a multi-tenant app, and the user who login to the app is in another AAD tenant, it needs the admin of that tenant consent the app, just let the global admin of that tenant to login the app, consent the permission. After the consent, other users in that tenant will also be able to login.
In your code, the authority need to be https://login.microsoftonline.com/common, then in the scopes of the request, it need to include the delegated permission scopes: ["/"], in my sample, it is scopes: ["api://xxxxxxx/Test.test"].

QUESTION
I am still new to AWS and am currently attempting to deploy my application utilizing AWS Elastic Beanstalk. I have 4 backend APIs that are available on my private Dockerhub and I have one frontend API that should communicate with these 4 backend microservices. I am able to deploy the 4 backend services to AWS Elastic Beanstalk by following the guide located here. My main problem or the part that I am failing to understand is how to get my frontend application to communicate with these 4 other services?
The current option I am looking into is adding my frontend angular application to the Dockerrun.aws.json so that my json file will look something like what you see below:
...ANSWER
Answered 2019-Oct-17 at 03:21The question seems broad but thing can be considered while working with the containers in AWS.
When I do this how do I retrieve the information in my angular app as to what the hostname will be for backend-svc-1?
You need to place Application load balancer on the top of these service and route request based on the hostname or request path to backend services when request route from Frontend application.
A high-level look with existing s3 angular app will be something like
Or will it be communicated to my frontend application via the links array as an environment variable?
Linking is use service for service to communication, for example backend-api want to communicate with Redis then linking suit but while your application is the web you angular application need to backend-api should be reachable from the internet so linking will not work in this but LBalancer will work fine.
I've seen other sites say I should manage my own ECS instances for each service and route the requests via API Gateway.
I prefer ECS when it comes to the container, now ECS offers different flavour like fargate, you do not need to manage or worry about infrastructure.
All you need to create 3 services
- Frontend
- Backend-svc-1
- Backend-svc-2
Place LB on the top of these services that's it. The frontend will use LB endpoint to communaite with backend service and service to service communication can use lining or service discovery.
But if backend-svc are same mean sharing same base code, you can should run two services of each task instead of running two separate containers.
A high-level look will be

I am new to docker compose and docker in general, so I am testing out a small example.
The problem I am trying to solve is how to have dynamic endpoints so that when I am running locally, http calls are made from my front-end to something like localhost:8080/getPeople, but when I am running these containers on digital ocean it goes to myDomain:8080/getPeople. I thought that was one of the main points in docker-compose and I am just missing something here. Here is my compose file.
ANSWER
Answered 2019-Mar-03 at 13:52Here's a setup using a reverse proxy so that you can use relative url (instead of messing with domain names in your webpages) and which also has the advantage of taking care of CORS issues you would have while making ajax calls to your backend.
If you are not familiar with reverse proxies, just know that all http requests should first hit the reverse proxy, and the reverse proxy will take care of forwarding those http requests to the correct http server following a set of rules.
In the docker world, a very convenient reverse proxy is Traefik. Below is an example of docker compose project with a reverse proxy, frontend and backend:
