aspect-oriented | Aspect Oriented Programming for JavaScript | Aspect Oriented library

Things I know (please correct me if I'm wrong, thank you :)):

• HttpInterceptor works in a way similar to Aspect-oriented programming;
• adding/modifying httpOptions can be achieved for requests;
• modifying the response with clone() can also be achieved for response;

I want to test some libraries while their related servers can be down sometimes when developing I just care about the data no interaction with server is okay

Is it possible that I can just return a mock data already prepared without requesting the server when the request met some patterns even the service lies in other libraries?

• all the logic in the libraries stays the same;
• using the mock data to respond to the http request from the libraries;

Thanks to the help of @Sachin Gupta, I tested the interceptor further with this demo.

What have been done:

• auth-interceptor.ts to add headers for the request;
• logging-interceptor.ts added to track the request details and time cost;
• data-mocking-interceptor.ts to stop the request to the server and return the mock data directly.

We are doing some research on Aspect-Oriented design and analysis. We are looking for a tool which integrates UML profile and supports AO modeling. I found some relevant papers, but none publishes an available tool. Does anyone know a tool that we can use? Thanks.

I have used aspect-oriented programming to do the logging in a Java Maven project.

While running it through eclipse I have to initialize javaagent in vmargs, as follows:

Trying to use Command/Handler pattern and Aspect Oriented Programming with Simple Injector.

I have my command and handler classes.

My algorithm loops over seconds of data. For each second-worth-of-data, I return a value, that is the result of a fairly involved computation involving multiple submodules and subclasses. Some of these classes are re-initialized each second.

For debugging purposes, a few times I have been in the situation that I have wanted to plot the value of a certain local variable in one of these classes over time. Something external would have to serialize and log the values, because the class exists for only a second. It has been a different local variable each time.

How can I do achieve my aim properly in terms of software design, without it taking me hours every time and without writing more than a line or two of new code each time I want to do this?

Ideally, one solution I have considered would be to have something like a global IO stream, or something like that, that I would "just be around" without having to initialize each class with it, so I could just insert some sort of MySerializer << [mylocalvariable, timestamp] command at any point in the code, and then when the run finished I could check if MySerializer is empty and if not I could plot what what is in it... or something like that. Better still if I could do this for multiple local variables in different classes. Would this solution be good? How could I do this?

Or to be able to do this in an aspect-oriented way, with some outside object "looking at the code" without changing it, building a buffer of values of that local variable, and spitting them out to a plot in the end. How might I do this?

Is there a better solution that either of these? Which design patterns suit this situation?

What I have done is in the past is to return that local variable to whoever holds the function, who then in turn has to return that value it has received, and so on and so forth, all the way up to the top. This is a huge mess and has to be written and deleted each time.

I have a logger that I am adding to my project. Right now for every method I'm going to have to write Logger.DebugLog("Starting Method") at the start of each method and Logger.DebugLog("Completed Method")

this logger - when Debug enabled - allows me to track exactly what methods were called on this run so that if there is an issue I can see how far it got before breaking making it easy to debug. Assume that the method name and line are being captured - my goal here is I do not want to add those two lines on every one of the +100 public or private methods

I am migrating my application from .Net Framework 4.5.1 to Dot Net Core. I was using RealProxy Class for logging user information and parameters on BeforeExecute and AfterExecute ( like this link)

Now it seems there is no such a thing in Dot core.Plus I don't want to use third parties.I found this link that is using Actionfilter but it won't do the job.

my question is How can I implement Dynamic Proxy in Dot net Core? Is there any alternate for RealProxy Class?

There is a framework called Go! Aspect-Oriented Framework for PHP

And it is made in plain PHP, doesn't require any PECL-extentions and DI-containers to work.

What's more can be integrated with any existing PHP frameworks and libraries (with or without additional configuration).

And there is no runtime checks of pointcuts, no runtime annotations parsing, no evals and __call methods, no slow proxies and call_user_func_array(). Fast bootstraping process (2-20ms) and advice invocation.

So I am very impressed, but what I want to know, is how does that actually work?

These points that I listed here...

I looked on github and official website, and some other articles but couldn't find any concrete information about how does this work (in general and in specific).

I'm so eager to know how does this work? How it was implemented?

The author of the article https://www.codeproject.com/Articles/1080517/Aspect-Oriented-Programming-using-Interceptors-wit is explaining on how to create an interceptor in "ASPNET Boilerplate" framework. In my case, I want to create an interceptor (or two interceptors, one for Start and the other for End) that will wrap the Unit of Work. I need to call a stored procedure called spStart when a method in any AppService starts, and call the spEnd when the calls are comitted to the database. Since the Unit of Work in ABP is also an interceptor, this is what I've done so far: Following the steps in the article I provided the link above, I did the following:

• Added two interceptors: StartInterceptor and EndInterceptor with their Registrar classes
• Registered them in the ApplicationModule class

• Also in the ApplicationModule I added the following code:

  IocManager.IocContainer.Register(Component.For() .Interceptors(InterceptorReference.ForType()).First, Component.For() .Interceptors(InterceptorReference.ForType()).Last, Component.For());

This code should make the StartInterceptor run first, and the EndInterceptor run last. Considering that the Unit of Work interceptor will be in between, and that we will be using the logic to await for the async method that is intercepted to return the result, that should give us the option to wrap the unit of work. However this is what happens: When the spStart runs, everything is ok. This stored procedure runs before the Unit of Work interceptor so no problems there. However, when the spEnd runs, it says "Transaction should be disposed before the connection can be used to execute SQL statements" or "The operation is not valid for the state of the transaction"... Seems that the UoW runs in parallel with my stored procedure. Has anyone else had the same issue with ABP? How did you solve it?
