sentry-java VS apollo-server

>As now we've introduced some peers code review, automatic testing on most critical stuff (but since the codebase sucks these aren't really reliable tests)

They may not be "reliable", but these are your safety net, or harness, so you don't fall. I wrote about similar issues, for instance here: https://news.ycombinator.com/item?id=26591067 and, given your promotion, here: https://news.ycombinator.com/item?id=37211796. It contains a few steps starting from "So...".

You can add monitoring, something like Sentry (https://sentry.io) will capture exceptions that were not handled that you have not seen because the stack trace is buried in hundreds of pages of logs or something. It groups them by exception and counts them. It's pretty awesome. (https://docs.sentry.io). It supports around 108 platforms (Java, Python, JavaScript, etc.). This lets you see the exceptions and makes prioritizing easier (which ones are the most frequent, which ones impact the most, etc.).

If you don't have them already, issue templates are really useful and the comment I linked to explains why, but here's an example of an issue template (again, you can configure them for different types of issues so team members select from a dropdown for a bug or a feature):

But, from my understanding, it targeted only software developers that would like to have super-deep insights into the applications and is not intended for monitoring simple apps like websites. Also, I have no idea even if I embed it, whether will it be able to tell me if my resources loaded or the performance didn't go well. For example, I don't see how I can easily embed it into my website: https://docs.sentry.io/ only programming languages are listed here.

Sentry provides informative guides for many platforms. In our server's case, we apply Apollo Server v2 as an Express middleware; therefore, Sentry's Express Guide with request, tracing, and error handlers is a great starting point.

The last step is to extract the openReplaySessionToken from the header and add it to your Sentry scope (ideally using a middleware or decorator) in your backend. The method to do this depends on the programming language of your backend, you can consult the Sentry docs on how to configure scope. The snippet below shows how to configure a Sentry scope if your backend is built with node.js/express

In a lot of cases crash report SDKs are open source?

Another interesting point is that executing fetches on the server can allow developers to more easily leverage caching. Next.js already handles caching out-of-the-box and I’m curious to see if the wider adoption of RSC reduces the need to combine React with solutions like Apollo Server and Apollo Client. While there are other benefits to these tools, RSC could provide similar caching behavior without the need to invest in a GraphQL solution.

There are several GraphQL server implementations, however, for this tutorial, we'll utilize Apollo GraphQL's Apollo Server, a lightweight and flexible JavaScript server that makes it easy to build GraphQL APIs.

As I mentioned, their main GraphQL server package is[1], so that's where the confusion came from. Thanks.

While working on this blog post, I learned that Apollo Server, the most popular GraphQL server for typescript, uses a similar method for adding error codes to GraphQL. It even lets you add custom errors. Hopefully, someday other GraphQL server projects will follow them. Until then, we’ve got a strong indication we took the right approach.

GraphQL is just a schema, there are many different implementations of a GraphQL server, AppSync being one of them. I mentioned Apollo server in this series as well.

After some head-scratching, I opened an issue on Apollo Server’s GitHub repository. There, Apollo Server contributor @​glasser shared a helpful suggestion: why not invoke our AuthPlugin from Apollo Server’s context function? Throwing from context would ensure we can control the HTTP status response without having to introduce more methods and error checks to our AuthPlugin (like unexpectedErrorProcessingRequest). With that suggestion in mind, we rewrote our AuthPlugin as follows:

Apollo as a middleware in Express.js, actually.

Lastly, instead of writing our API core ourselves, we'll be using the star of this episode --- Apollo Server (a.k.a. GraphQL server). It has detailed documentation available here.
