Announcing .NET Community Toolkit v8.0.0 Preview 3

As we’re getting close to the official launch of the new .NET Community Toolkit, we’re happy to announce that the third preview of the upcoming 8.0.0 release is now live! As is the case with every new public preview, there’s lots of new features to explore, as well as several improvements and bug fixes. Once again, all changes were influenced by feedback received both by teams here at Microsoft using the Toolkit as well as other developers in our community. We’re so thankful to everyone that has contributed and is helping the .NET Community Toolkit get better every day! 🎉

As a small refresher, the 8.0.0 release will be the first release from the brand new .NET Community Toolkit repository, which will be the home of all our general .NET libraries going forward. Libraries in this new toolkit have no dependencies on any specific UI frameworks, so they can be used by all developers regardless of the framework or runtime they choose to work on their projects. These libraries multi-target .NET Standard 2.0 and .NET 6, so they can both support as many platforms as possible and be optimized for best performance when used on newer runtimes.

CPU Usage Tool Improvements

With Visual Studio 2022, we have converted the CPU Usage tool in the Performance Profiler to the profiler’s new analysis engine. This new change provides the tool with better source resolution, incremental/cancelable symbol loading, a performance boost, and a new flame graph.

Note: This is only available in the Performance Profiler (Alt+F2) version of the tool, but we are still working on supporting it in the Diagnostic Tools. Give it a shot and see what insights you can find!

Anti-corruption Layer for mapping between Boundaries

What does an anti-corruption layer solve? Most systems rely on data or behaviors from another service or an external 3rd party. The problem is they often don’t share the same semantics or data structures. Left unchecked this leads to convoluting up your own boundary with concepts from another boundary. Let me explain how you can use an anti-corruption layer as a way to translate the concepts from another boundary in isolation.

Middleware in ASP.NET 6 - Conditionally Adding Middleware to the Pipeline

Welcome back! So far in this series, we've covered the basics of Middleware in .NET 6 applications, shown how to create custom Middleware classes, and discussed why the order of operations of the Middleware pipeline is so important.

In this final part of the series, we will show two ways to conditionally execute middleware in the pipeline: by using settings in the AppSettings.json file to determine whether or not to add the middleware to the pipeline in the first place, or by using the incoming request's data to conditionally execute a middleware piece already in the pipeline.

Writing Redux Reducers in Rust

At Fiberplane, we are building a collaborative notebook editor for incident response and infrastructure debugging. As part of the challenges we faced implementing such an editor, we had several complex functions written in Rust that we had to use on the frontend through WebAssembly.

This post will explore how we integrated this WASM code into a React/Redux application, as well as why we ended up writing our own bindings generator for it.

Test component interactions with Storybook

Components fetch data, respond to user interactions, and manage app state. To verify this functional behavior, developers rely on automated tests. But most testing tools are Node and JSDOM based. That means you’re forced to debug visual UIs in a textual command line.

At Storybook, we’re improving component testing by using the browser to run tests. Over the past six months, we introduced several features—play function, test-runner, assertion library—to make this a reality. This article walks through the entire Storybook interaction testing workflow.

When Does React Render Your Component?

When and why does React render my component exactly?

This post is my version of Mark Erikson's essay A (Mostly) Complete Guide to React Rendering Behavior where I try to answer one of the most commonly asked questions in this React community – "when or why does React render my component?" – with a tiny amount of React source code walkthrough.

Normally I am not a big fan of drilling down to the implementation details and you certainly don't need to know that in order to be productive in React. However, when it comes to understanding the rendering behaviour and rules for bailing out of re-renders, the React docs haven’t provided a thorough enough explanation to satisfy me. Therefore to adequately answer those questions, I had to peek into the source code. That being said, this is not going to be a post about hard-core source code walkthrough. If you are interested in that, here is a great series made by JSer that you should check out.

All React Hooks and Concepts In A Single Post!!

First of all React is a JS Library not a Complete Framework 🙂 so for making a complete web application you need to know a lot of other things 🤭 that you can use with React. In this Post I will cover React concepts, Hooks and some good practices Ofc... 😁
We use React to make reusable components that can be used in a logical way to make UI. Making components in React is as easy as making a function 🤩.
For Example 👇🏻 it is a simple react component in which we can pass data as arguments which can be easily referenced inside the functions.

Software Architecture

The project with a single 11,000-line code file

A long time ago at one of my first software jobs, I received a bug report for a internal product that I didn't even know existed.

It turned out to be an application that serves up basically every form that any employee within the company might need. Essentially a catch-all resource. Do you need to report someone to HR? There is a form for that. Do you need a contract for a new client? There is a form for that.

The responsibility of maintaining the project had been bounced from team to team over the years. Apparently it belonged to my team. And by my team, I mean me.

Cloud, Load, and Modular Code: What 2022 Looks Like for Shopify

You may have heard that 2021 was Shopify’s biggest Black Friday Cyber Monday (BFCM) ever. This four-day period was monumental for both Shopify’s merchants and our engineering teams.

Last year’s numbers capture a moment in time but can also help us predict what’s to come in the year ahead. On our cloud in 2021, our peak BFCM traffic surpassed 32 million app server requests per minute (RPM). In the same time period our load balancers peaked at more than 34 million RPM. To put that in perspective, this means that the equivalent of Texas’s total population hit our load balancers in a given minute. One flash sale—a short-lived sale that exceeds our checkout per minute threshold—even generated enough load to use over 20% of our total computing capacity at its peak.

How to design a system to scale to your first 100 million users

It is not easy to design a system that supports hundreds of millions of users. It always is a big challenge for a software architect (but it’ll be easy from today after reading my article 🤣)

Here are some topics covered by me in this article.

  • Start with simplest: all in one.
  • The art of scalability: scaling out, scaling up.
  • Scaling a relational database: master-slave replication, master-master replication, federation, sharding, denormalization, and SQL tuning.
  • Which database to use: NoSQL or SQL?
  • Advanced concepts: caching, CDN, geoDNS., etc.
