I created an asp.net-angular webapp mainly according to a course I was in. Deployment wasn’t covered in the course and I have run into a lot of trouble trying to deploy my app. (I have been using vscode throughout the entire proccess).
I have understood that the best way to do this is to package it for docker, and in order to do that I should package it all together so that the .net project also starts up the angular project. Until now, I have been running them on ports of localhost, by using ng serve and dotnet run commands in separate terminals. I have tried hooking up the projects according to a bunch of different tutorials I found but haven’t been able to get it working.
I don’t fully understand the different configuration files, I have read the documentation, but it seems the information I lack is supposed to be obvious and therefore doesn’t seem to be explained in depth. what url needs to be pointing to what etc.
I realize this question is kind of all over the place, and I haven’t given specific code samples, but part of my problem is that I don’t understand which of the many configuration files in the project are the ones relevant for this.
I will happily supply any files needed.
Any help or direction will be greatly appreciated.

I have recently started learning about Alfresco Content Service.
I have some questions:
My understanding is that the standard way to add customization is to create AMP's.
Why create an amps for each customization instead of adding it directly to the configurations of ACS? Are there some benefits like not having to restart the service or something?
If apply_amps adds all custom amps to the alfresco server (.war files), won't there be a risk of customizations writing over each other?
E.g if two different amps change the same standard button in the share service.
I have found that there are 2 ways to add these customizations as well:
Add dependency to the pom file. (works only for .jar)
Actually compile the .amp and move it to the correct folder and run apply_amps.sh.
From the documentation it seems to my like AMP-files used to be the standard way of adding customization but that there have now been a move away from this in favor of using regular jar files and eventually in 7.1 and forward use JSON instead.
Yet other tutorials I find mentions things like "always use .amp". Which then seems strange if it contradicts the information on the official documentation.
Also I found something about adding amps through the share interface? Or must they always be added when building the server (.war)?
Could someone provide me with a thorough explanation of the best practice for applying customizations to the alfresco content service? Preferably with details regarding a live production setting.
Thanks for helping me make some of this clearer.
I'll try to give you helpful answers:
Making app packages (APMs or JARs) is much better than changing config manually. It's good for versioning, portability (TEST vs PROD or between projects), composition (you can add some addons witch are often very useful)... It is standard and good way how to build a web app.
About conflict of customizations, I'm not sure how it works. Is good practise always use own namespace for every AMP.
If AMPs write to the same file, result is always append (share-config-custom.xml can get be very big).
Problem about JARs and AMPs is simple. Old version of Alfresco supports more AMPs than JARs. Now it does not matter with way you use. Try to look inside these packages they look very similarly.
I never heard about adding AMPs through the share interface. Have you some source? Only thing which is similar is creating content model through Model manager (https://docs.alfresco.com/content-services/latest/tutorial/model/)
I use for PROD combination of AMPs and JARs. I have a lot of legacy code and addons in AMPs and new things in JARs. Alfresco work with them same...
I'm really keen to use the 2sxc environment on my website for a number of applications.
I'm currently looking at the Mobius forms.
What I'm wanting to do is create a ticket in ConnectWise rather than send an email, using the ConnectWise REST API.
Some of these questions might have obvious answers to someone who has been taught in these technologies, but I'm self-taught. When I went to school I learnt COBOL!
There is c# code in the application, but I can't see how you build and incorporate into the application. I forked the code and it seems to just code with no build.
There are live and staging folders with the same cshtml files. However, it seems a bit random when the live or staging is actually used. For example, I did a quick fix to the _Contact Form.cshtml so to fix the type that meant it always displayed the ReCaptcha warning, and I changed the live version, which didn't do anything, so I had to change the staging version.
I need to update the settings so that configure the ConnectWise API settings, I haven't been able to find where I can do this? I am still looking though.
I also need to store a private key in the settings. Is there a secure way I can do this?
PS. When I get my head around all this I'm happy to be a contributor
welcome to StackOverflow.
I'll try to give you some guidance to help you figure it out
Live and staging are folders meant to let you make changes while the users see the unmodified output. So a host-user sees the files from staging, others see what's in live. When you're done and all is tested, you copy from staging to live. This we call Polymorphism.
Polymorphism applies to both the cshtml as well as the api. So as a host-user, you'll be using staging/api/FormController to save/send.
There is no build process, everything is hot-compiled. That's one of the things that makes 2sxc so amazing. No Visual Studio, DLL or restarting the application ;) You'll love it.
Secure keys: there is no special secure key storage. We usually put it in the App-Settings, just like the MailChimp key you'll see there. We split it into two fields for very technical reasons, because we publish our code on github and that causes trouble when our code has API keys. But you can just use one field, assuming you don't plan on publishing the code on github.
I want to develop Document Manager application based on Alfresco. I am going to change there many things: user interface, language, may be some functions... But I don't know how to start, where I can get Alfresco source code, how can I rewrite codes with netBeans and how can I test my changes. This is my first serious project so I need any help. Where I can get Started ?!
A very popular way to get started is to work through my tutorials.
You don't need the source code, although it is available and helpful when you are troubleshooting or learning how something works. Instead of forking Alfresco you will write extensions that customize the platform. If you find yourself needing to compile Alfresco's source code, most likely you are doing something wrong.
I am building a series of interactive shiny web apps for a project that I am considering turning into a Company. My background is in data science and I don't have a lot of experience on the web app / server side of things, but these are important aspects for me to consider with my project. I currently have an Amazon Linux AMI EC2 instance with ShinyServer (free, open-source) installed, and I am currently hosting early versions of my web apps there. So far everything works fine, but I haven't made the links public yet.
My first question is whether anyone knows if there are certain limitations (scalability limitations, integration with database limitations, security / authentication limitations, etc.) that I will inevitably run into using RShiny apps and ShinyServer? I haven't heard of many successful, super-popular web apps being shiny apps hosted on ShinyServer, but rather my feeling is that ShinyServer is mainly used for hosting RShiny apps that are shared amongst only a small number of people (i.e. shared amongst team members at a company.). Per this thread - Does R-Server or Shiny Server create a new R process/instance for each user? - I am particularly concerned that my app won't be able to handle thousands of users simultaneously since only 1 R process is created for the app regardless of the # of concurrent users of the app. Having 10-20 processes through ShinyServer pro probably doesn't solve the issue either if I ever intend to scale greater than the hundreds or thousands of users. I also noticed that ShinyServer Pro would run me a not-so-negligible $10K per year.
My second question is whether RShiny apps can be deployed using other server technologies, such as Heroku. I came across this github page (https://github.com/virtualstaticvoid/heroku-buildpack-r/tree/heroku-16) but haven't dug too deep into it yet. I've been told that heroku makes it easy to update releases to apps whose code is on github (git push heroku:master), amongst other things.
My third question involves certain specific considerations of mine. In particular, I am currently working on a script that queries data from an API and writes that data to a (not-yet-setup) database of mine. This is the data my apps use, and I'd be interested in having the apps update in real time as the database updates, without requiring the user to refresh the webpage. A buddy of mine suggested AJAX for this type of asynchronous behavior, and it looks like this may be possible in R with something like this (https://github.com/daattali/advanced-shiny/tree/master/api-ajax).
Sorry that this is such a loaded question, but I hope it doesn't get closed down as I think it is fairly educational. Any suggestions / sources / pointing me in the right direction would be greatly appreciated on this.
Canovice,
I'd recommend you take a look at the following RStudio / AWS support articles. To scale a shiny server you'll need to look at using a load balancer:

AWS

Blog Article:

Shiny is a great platform, their support is fabulous. I'd recommend you ring them up - they'll be sure to help answer your questions.
That said if your plan is to create a scalable website that will support thousands or hundreds of thousands of people then my sense would be to recommend you also review and consider using D3.js in conjunction with react.js or Angular.js, not forgetting to mention node.js.
My sense is that you are looking at a backend database connected to a logic engine and visualisation front end. If you are looking for a good overview of usage take a look at the following web page and git repo [A little dated but useful]:

https://github.com/anmolkoul/node-dc-mongo
I hope the above points you in the right direction.
I'd like to provide some notes related to your second question: Yes, you can use the mentioned buildback to deploy shiny applications on heroku.
I was in a similar situation with you (asking myself about possible ways of serving Shiny applications in a scalable manner) and decided to go the "heroku way".
You may find these hints helpful when deploying your app to heroku using the buildpack mentioned above:
Heroku tries to "guess" how to execute your application. But you can also add a special file, named Procfile, to your application to control the process commands you want to execute for your application. In my case I used web: R -f ~/run.R --gui-none --no-save, where this means that a file named run.R is being passed to the R executable for the web server process
The stack on heroku is based on Ubuntu. If you need additional deb-packages, you can create another special file named Aptfile and add the package names therein, heroku will then automatically install these for you (I needed it for RPostgreSQL)
You can add another special file named init.R and install all R packages as necessary just as you are used to, i.e. with install.packages etc. You can also add initial configuration material within this file.
As a running example, here is an example toy application that I wrote for myself to remember how a "full-stack" shiny app may look like, including compability with heroku.
For a large number of concurrent users, use a load balancer like nginx and enable the autoscaling of your app, e.g. through Kubernetes.
You can deploy your app on Heroku. On the paid tiers it includes NoOps autoscaling of your app. See this tutorial on how to deploy a Shiny app in a Docker container on Heroku: https://medium.com/analytics-vidhya/deploying-an-r-shiny-app-on-heroku-free-tier-b31003858b68
You can query the table last update timestamp in the Shiny server logic with reactivePoll() and rerun your db query if it changed. It is not "real-time" but depending on your application close enough if you set the time interval small.
Currently, we have a long list of various websites throughout our company's intranet. Most are inside a firewall and require an Active Directory account to access. One of our problems, as of late, has been the increase in the number of websites and the addition of a common code library that stores our database access classes, common helper functions, serialization methods, etc. The goal is to use that framework across all websites throughout the company.
Currently, we have upgraded the in-house data entry application with these changes consistently. It is up-to-date. The problem, however, is maintaining all of the other websites. Is there a best practice or way in which I find out versions on each website and upgrade accordingly? Can I have a centralized place where I keep these DLLs and sites reference them? What's the best way to go about finding out what versions are on these websites without having to go through each and every single website, find out the version, and upgrade after every change?
Keep in mind, we run the newest TFS and are a .NET development team.
At my job we have a similar setup to you, lots of internal applications that use common libraries, and I have spent the best part of a year sorting this all out.
The first thing to note is that nothing you mentioned really has anything to do with TFS, but is really a symptom of the way your applications, and their components, are packaged and deployed.
Here are some ideas to get you started:
Setup automated/continuous builds
This is the first thing you need to do. Use the build facility in TFS if you must, or make the investment into something like TeamCity (which is great). Evaluate everything. Find something which you love and that everyone else can live with. The reason why you need to find something you love is because you will ultimately be responsible for it.
The reason why setting up automated builds is so important is because that's your jumping off point to solve the rest of your issues.
Setup automated deployment
Every deployable artifact should now be being built by your build server. No more manual deployment. No more deployment from workstations. No more visual studio Publish feature. It's hard to step away from this, but it's worth it.
If you have lots of web projects then look into either using web deploy which can be easily automated using either msbuild/powershell or go fancy and try something like octopus deploy.
Package common components using nuget
By now your common code should have its own automated builds, but how do you automatically deploy a common component? Package it up into nuget and either put it on a share for consumption or host it in a nuget server (TeamCity has one built in). A good build server can automatically update your nuget packages for you (if you always need to be on the latest version), and you can inspect which version you are referencing by checking your packages.config.
I know this is a lot to take in, but it is in its essence the fundamentals of moving towards continuous delivery (http://continuousdelivery.com/).
Please beware that getting this right will take you a long time, but that the process is incremental and you can evolve it over time. However, the longer you wait the harder it will be. Don't feel like you need to upgrade all your projects at the same time, you don't. Just the ones that are causing the most pain.
I hope this helps.
I'd just like to step outside the space of a specific solution for your problem and address the underlying desire you have to consolidate your workload.
Be aware that any patching/upgrading scenario will have costs that you must address - there is no magic pill.
Particularly, what you want to achieve will typically incur either a build/deploy overhead (as jonnii has outlined), or a runtime overhead (in validating the new versions to ensure everything works as expected).
In your case, because you have already built your products, I expect you will go the build/deploy route.
Just remember that even with binary equivalence (everything compiles, and unit tests pass), there is still the risk that the application will behave somehow differently after an upgrade, so you will not be able to avoid at least some rudimentary testing across all of your applications (the GAC approach is particularly vulnerable to this risk).
You might find it easier to accept that just because you have built a new version of a binary, doesn't mean that it should be rolled out to all web applications, even ones that are already functioning correctly (if something ain't broke...).
If that is acceptable, then you will reduce your workload by only incurring resource expense on testing applications that actually need to be touched.
