kandi X-RAY | webapp Summary
Build webapps with React, Redux, Webpack, GraphQL. They render on the server and reuse state on the client. New pages are loaded on the client only. Code is split into separate chunks per page. Even Redux Reducers are split. This allows building arbitrarily huge websites from a single codebase.

QUESTION
I have a third party .war file that I run on a Jetty server. I need to run code for logging purposes before the filters defined in the .war file's deployment descriptor run. The code needs to have access to the incoming request and the response object and to the context of the logger that runs for the app in the war.
Is there a way to do this in Jetty's xml configuration file? I don't want to touch the war file due to concerns about license.
I could override the deployment descriptor which would allow me to add custom filters but I believe these would then run after the filters in the war. I could also use a request customizer but that doesn't give me access to the response which I also need to edit.
I tried adding a handler to a HandlerCollection before the handler with the org.eclipse.jetty.webapp.WebAppContext that runs the war but it doesn't seem that I have access to the web app's logger's context...
Is there any way to do this? So before the web app's servlet executes run a piece of code that can access the incoming request and the response and the web app's context?
...ANSWER
Answered 2021-Jun-15 at 17:41Option 1:
To access the raw Request and Response at the various stages of their lifecycles, use the HttpChannel.Listener (make sure you read the javadoc/apidoc to understand what each event means).
Option 2:
To add a handler in the WebAppContext, before the Session/Security handling, but after other handlers, use WebAppContext.insertHandler(HandlerWrapper).
Option 3:
Create a web-fragment servlet jar that represents your servlet Filter, and add it to the WebAppContext.setExtraClassPath(String), which will be picked up and added to the actual webapp's startup.
Option 4:
Create a custom RequestLog implementation (that you add to Server.setRequestLog(RequestLog) that is notified once the request AND response are complete, so you can log the state of the request/log to whatever source you want.
Option 5:
Use one of the existing RequestLog implementations to log the details you desire to the console in the format you desire. (Look at the combination of CustomRequestLog and Slf4jRequestLogWriter)
QUESTION
When setting up an Azure Static WebApp when I chose GitHub as the source provider, the UI provides an option to choose from one of the existing branches. But once the app is created I don't see any option to change the source. Whereas in Azure "App Service", you can disconnect from GitHub and establish the connection again with a different branch.
So, Is it possible to change the source branch in Azure SWA?
...ANSWER
Answered 2021-Jun-15 at 16:36You might've sorted it out by now, but this confused me as well and it turns out that you set this up on the deployment setup. In my case I'm using DevOps/Pipelines, and on the pipeline (equivalent to Github Actions) you can choose which branch to source from. Then you run the pipeline, and that will automatically change the source in the Static Web app.
QUESTION
Dears, I have a jersey - spring api deployed on apache tomcat 9.0.46. (Jersey to handle restful services JAX-RS and Spring to handle all my beans{controllers, DAO, SessionFactory, JPA etc...}). Everything works fine on tomcat 9 on windows... When deploying the exact same war in ubuntu tomcat 9.0.46, the ContextLoader is getting triggered 3 times and I have all my singletons instantiated 3 times. I'm deploying the api on tomcat ports 80 and 443 (https - godady certificate). once I start tomcat the war is deployed and ports 80 and 443 get started (netstat -tulnp | grep java) and I see in log all singletons instantiated. (pool-2) Applicationcontext class my custom spring @Configuration class and it is getting triggered and DB is accessed without any issues
...ANSWER
Answered 2021-Jun-14 at 12:43I have managed to figure out the problem. The issue was related to tomcat configuration in /conf/server.xml. Multiple Hosts will trigger the context loader to be triggered for each. I was keeping the default appBase to webapps for all host thus triggering the ContextLoader of each my war for each host. Another reason the ContextLoader will triggered multiple times as well is defining the option inside unless you need to load something external to your war. I recommend reading specs: https://tomcat.apache.org/tomcat-4.1-doc/config/host.html
QUESTION
I have an OpenID Connect server (OpenIDdict) and an asp.net core webapp in containers behind a TLS termination proxy. In production, all communication between the webapp and the OIDC server can go through the 'outside', based on their public names. However, in development, I'm using self signed certificates that aren't trusted by the containers running the apps, only by my host pc. Because of that, in development, the webapp can redirect the browser to the OIDC server just fine, but when it, for instance, needs to call the token endpoint, it will fail, because the certificate isn't trusted.
A possible solution would be to have the server to server communication go through the internal container network, but I haven't been able to get that to work. Is there a way to make the asp.net core OpenID Connect middleware use a different url (and protocol) for server to server communication?
Another solution would be to install the self signed certificates in the containers, but because that's only needed in development, it seems bad practice to burden the images with that. Is that assessment correct?
I'm hoping I'm missing the most obvious solution. Any ideas?
...ANSWER
Answered 2021-Jun-14 at 12:33This is what I ended up doing:
- I added a custom domain to the hosts file of my pc, pointing to itself.
- Using openssl, I created a rootDevCA.crt and added it to the trusted root on my pc and in all the container images.
- With that root certificate, I signed a new certificate for the custom domain and supplied that (including its key) to the proxy.
As long as I keep the key file for the root certificate far away from my source code, there should be no security issues.

My mistake was thinking that the webpack ts-loader would take context from from ts-config file and transpile the typescript according to that and webpack the content into the final bundle. Upon looking at my question again ive realised i put the index.tsx file as my entry point which is why i was still getting a bundled webpack file but my imports were undefined the only file being webpack was my index file i believe. That combined with the single file output tsc seems to have been the cause.
tsc was creating a bundle of my typescript.
webpack was creating a bundle of just my index.tsx file

I've made a webapp for a simple marketplace. I have three different functions: searching, filtering, filtering by keys. Each of these functions contains different query parameters. My problem is that how should I separate these endpoints in a rest way?
For example, this is my endpoint for searching:
...ANSWER
Answered 2021-Jun-13 at 20:47My problem is that how should I separate these endpoints in a rest way?
REST doesn't have "endpoints". It has resources and resource identifiers.
What is the correct approach for this?
For all of these, you should use GET (the semantics of the request are effectively read only), with the parameters you need embedded in the URI somewhere. It's largely up to you where in the URI the parameter should be.
On the web, we usually want to choose identifiers that make it easy to support a web search form, which usually means describing the parameters as a list of key value pairs, so you end up with something like:
