Project mention: Mastering Real-Time Collaboration: Building Figma and Miro-Inspired Features with Supabase | dev.to | 2024-05-11Supabase is a backend as a service visual platform that allows you to create postgres DB with minimum code. Their documentation is so good that it feels like home and you can get your project online in no matter of time.
ExcelJS and XLSX (SheetJS) are great libraries to work with XLSX files. The former I've found a bit easier to work with but less efficient in general.
Project mention: Tech Note: Type inference takes place when initializing variables and members | dev.to | 2024-05-14Officail documentation
Project mention: What is JSDoc and why you may not need typescript for your next project? | dev.to | 2024-01-22Besides the features TypeScript itself proposed, the most important thing it brought to the community was the ability to create cool features around this compiler that enhance the developer experience and productivity. Tools like tsserver, pretty ts errors, and many others are actively improving the ecosystem for both JavaScript and TypeScript writers.
Deno: Deno with one of it's frameworks (like Fresh
The most interesting JS DB lib I came across was https://github.com/kysely-org/kysely but still didn't feel as good as EF Core.
graphql: GraphQL middleware that wraps the GraphQL Yoga library
For this article, we'll leverage the 'Simple CRM' project from our previous list of projects. We'll integrate and utilize the i18n library to internationalize our application.
Project mention: The Notifier Pattern for Applications That Use Postgres | news.ycombinator.com | 2024-05-14Great post!
Postgres.js actually does this implicitly through a simple API[1] mimicking the postgres way, thereby using only a single dedicated connection for listening per process.
Listen/notify is also super useful with triggers.

Project mention: I don't get fresh. why can't I use react without commiting to a server side framework? | /r/Deno | 2023-07-01Check aleph if you want to use react with deno. But I'd suggest sticking with Node.js and Vite as you'll get less surprises.
