Project mention: Bun - The One Tool for All Your JavaScript/Typescript Project's Needs? | dev.to | 2024-04-02NodeJS is the dominant Javascript server runtime environment for Javascript and Typescript (sort of) projects. But over the years, we have seen several attempts to build alternative runtime environments such as Deno and Bun, today’s subject, among others.
I didn't really give much thought as to which backend I would use. I already had 2 projects in Supabase (BOXCUT & MineWork), but also a few projects in Firebase too. I was more concerned at the time at actually building the product.
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: I used Cloudflare Workers and R2 as HTML generating service. It was so easy! | dev.to | 2024-04-26I used hono to implement worker.
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.

Project mention: Show HN: Tsynamo – Type-friendly DynamoDB query builder for TypeScript | news.ycombinator.com | 2024-04-10Hello HN! I was recently introduced to Kysely (https://github.com/kysely-org/kysely), a type-safe Typescript SQL query builder, and instantly fell in love! I got inspired and wanted to make something similar for AWS DynamoDB.
Thus, I developed Tsynamo! Instead of calling it type-safe, I decided to go with type-friendly, because the library is still in an early stage, and is not 100% type-safe.
Under the hood, Tsynamo compiles the built queries into AWS SDK v3 commands. I feel that Tsynamo simplifies the AWS SDK API quite a lot since the developer doesn't have to mess around with condition/filter expressions or attribute names/values themselves, and as a bonus gets autocompletion for building the queries!
There's also a playground to test it out in your browser: https://try.tsynamo.dev. It might not have the most up-to-date API of the library in use yet, but you can get the library's main idea from there.
Since the project is still in its early stages, it doesn't yet have 100% support for all DynamoDB features, like querying indexes. The next steps will be increasing the support coverage and perhaps adding automatic type generation as inspired by kysely-codegen (https://github.com/RobinBlomberg/kysely-codegen).
Would love to get some feedback, thanks in advance!
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: Neon Is Generally Available: Serverless Postgres | news.ycombinator.com | 2024-04-15I want to use this as a chance to bring attention to a GitHub issue that I think would help reduce friction for Neon:
https://github.com/neondatabase/neon/issues/4989
If the Neon driver were to allow us to easily pass in a localhost connection, the development and test experience would be easier. Perhaps Neon could swap to something like this internally: https://github.com/porsager/postgres.
Having run a local dev environment connected to Neon and tests connected to Neon got in our way of adoption. We'd prefer to develop and run tests against a regular Postgres localhost database.
To the PMs of Neon, put yourself in the shoes of a new developer thinking of giving Neon a try. What changes will I have to make to my code and my development workflow?
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.

Project mention: Pigz: Parallel gzip for modern multi-processor, multi-core machines | news.ycombinator.com | 2023-05-12Similarly, if people are interested, I have coded the possibility to compress zip files on several cores in zip.js [1]. The approach is simpler as it consists of compressing the entries in parallel. It still offers a significant performance gain though when compressing multiple files in a zip file, which is often the nominal case.
