JVM Profiling in Action
Most of the time is spent in JSON parsing, specifically in AccessLogAggregator.parseLineJson. Within parsing, the majority of time is spent in org/json/JSONObject.. Since there are faster JSON libraries available, we'll switch to Gson and repeat the tests. To do this, we'll add the following method to our code:

Data API for Amazon Aurora Serverless v2 with AWS SDK for Java - Part 3 Executing update and insert SQL statements in batch
In this concrete example we'll create 3 products. We can then convert this JSON to the list of products using Gson.

Gson has been in maintenance mode for at least 6 years. It's kind of a shame, because the API and implementation were a lot cleaner than Jackson.

For more information on native-image build arguments, please consult the GraalVM Native Image Options documentation. The next listing contains the contents of reflect.json, which contains a bunch of data classes that we need to serialize and deserialize with Gson, as well as our Lambda handler class which the runtime needs to instantiate based on the qualified class name passed to the Lambda function.

The loadModel() method is special. It needs to dynamically update the model path specified in the JSON-formatted template file according to the extraction path of the Jar package. Gson can be used to load and update the JSON object.

how do i return multiple values from an api
I am not sure if this is what you are looking for, but allot of projects that I worked on used gson to convert between Java objects and JSON strings (https://github.com/google/gson). Maybe you should check it out.

How can I use ConvertFrom-Json with JSON containing java.util.Arrays$ArrayList?
Since this JSON contains the JSON representation of Java objects that are unknown in PoSh/.NET, all you could do is extract the provided object data (values), but not the objects themselves. In order to extract the "real" objects as they're defined, you'd have to start from the Java side, and use a tool like Gson.

Securing Vue Apps with Keycloak
In this article we'll be using Keycloak to secure a Vue.js Web application. We're going to leverage oidc-client-ts to integrate OIDC authentication with the Vue app. The oidc-client-ts package is a well-maintained and used library. It provides a lot of utilities for building out a fully production app.

Top 6 Open Source Identity and Access Management (IAM) Solutions For Enterprises
KeyCloak is a Cloud Native Computing Foundation (CNCF) project that offers enterprise IAM solutions. Keycloak emphasizes proficient enterprise authorization solutions by providing:

Outline only uses SSO for authentication. The solution when self hosting is use a private keycloak server [1]. This allows you to do email based auth.

What Is OIDC?
> Don't outsource either your authentication or authorization. Run it in-house.
This is hard to do, though. I hope people here will drop a lot of combinations that work for them!
Personally, for a small/medium scale project, I went with:
Keycloak: https://www.keycloak.org/
It supports various backing RDBMSes (like PostgreSQL, MariaDB/MySQL and others), allows both users that you persist in your own DB, as well as various external sources, like social login across various platforms, is an absolute pain to configure and sometimes acts in stupid ways behind a reverse proxy, but has most of the features that you might ever want, which sadly comes coupled with some complexity and an enterprise feeling.
I quite like that it offers the login/registration views that you need with redirects, as well as user management, storing roles/permissions and other custom attributes. It's on par with what you'd expect and should serve you nicely.
mod_auth_openidc: https://github.com/OpenIDC/mod_auth_openidc
This one's a certified OpenID Connect Relying Party implementation for... Apache2/httpd.
Some might worry about the performance and there are other options out there (like a module for OpenResty, which is built on top of Nginx), but when coupled with mod_md Apache makes for a great reverse proxy/ingress for my personal needs.
The benefit here is that I don't need 10 different implementations for each service/back end language that's used, I can outsource the heavy lifting to mod_auth_openidc (protected paths, needed roles/permissions, redirect URLs, token renewal and other things) and just read a few trusted headers behind the reverse proxy if further checks are needed, which is easy in all technologies.
That said, the configuration there is also hard and annoying to do, as is working with OpenID Connect in general, even though you can kind of understand why that complexity is inherent. Here's a link with some certified implementations, by the way: https://openid.net/developers/certified-openid-connect-imple...
