electron-builder
A complete solution to package and build a ready for distribution Electron app with “auto update” support out of the box
Electron React Boilerplate(ERB) is a pretty easy way to start building a desktop app in no time. It uses electron-builder under the hood to power build and publish step of the application and for building the frontend it uses Webpack. Just clone the repo and you're ready to go. For this setup let's use the name agent-desktop-app.

mitosis
Write components once, run everywhere. Compiles to React, Vue, Qwik, Solid, Angular, Svelte, and more.
I explored libraries like Valtio and Mitosis, but neither fit perfectly. I didn’t want to add a peer dependency for Valtio, and Mitosis didn’t work well with a shared context.

The problem was related to the implementation of @angular-devkit/build-angular:dev-server. After analyzing other builders, such as custom-esbuild, a solution was found. Using the approach from this example helped to successfully complete the build of host-application:serve. On http://localhost:4200/ everything looked correct, but only thanks to SSR. With disabled SSR, there was an error:

Project mention: 5 years ago I started to work on the next-gen fetcher, here it is | news.ycombinator.com | 2025-07-14
About five years ago, I began developing what I hoped would be the data fetcher of the future - HyperFetch. It was a long and challenging journey, but I believe it has turned out to be successful and I hope it will be useful to the community.
So what is HyperFetch?
In short, it’s a data-fetching library. If you take Axios and TanStack Query and combine them into one, you get HF. The name doesn’t imply faster network requests. My goal was to speed up development, improve usability, and eliminate repetitive, tedious boilerplate. It should be quick to write and easy to maintain, while also scaling well.
I’ve spent most of my career building UI kits, reusable architectures, and components to empower developers at the organizations I’ve worked with. After thousands of hours and many years, I feel I’ve poured all that experience into this library.
Along this path I was inspired by many - trpc, tanstack query, swr, rtk, axios, shadcn - but I think my approach is a little different. I integrated the hooks directly with the fetching logic to give them a deeper understanding of the data flow and structure.
There are good reasons to remain agnostic and provide very open-ended hooks, like in tanstack query or swr. But there are also many reasons why a more tightly coupled system like HyperFetch can be powerful. We know the expected data structure, can track upload/download progress, and even support real-time communication which I do with dedicated "sockets" package.
You’ll find more reasons and examples of how HF can improve your workflows in the comments. I’ll leave you with our brand-new docs to explore!

Project mention: Best headless CMS for Next.js - Typescript support comparison | dev.to | 2025-01-22
Although the contentful-userland/cf-content-types-generator package seems to be less popular than the Intercom one, it seems to provide better compatibility with the Contentful Typescript SDK.
