Project mention: The Joy of Mixing Custom Elements, Web Components, and Markdown | news.ycombinator.com | 2025-08-11
I recently discovered a static site generator called Astro, which supports many syntaxes but the .astro is a nice mix of TypeScript and JSX-like syntax. Content can use MDX which is like Markdown but with {JSX} style markup for variables and etc. The static components are used very similar to React, with familiar import statements and patterns. It is extremely easy to pick up. Best of all, it has plugins to support all sorts of other interactivity, so you can create interactive 'islands' of content using React or Preact or SolidJS or Vue etc. That way you have most of your content statically generated, and then the dynamic parts can be done from the client side.
Best of all, if you use simple unchanged files for other dynamic stuff like JSON etc, you can just generate those on build and serve those files in the host directly as the 'response' to a simple REST request, which is sometimes overlooked despite being the most fundamental form of a REST API.

slate
A completely customizable framework for building rich text editors. (Currently in beta.) (by ianstormtaylor)
However, I had difficulties inserting editable BLOCKS with syntax highlighting for code. Yes, there is an official example, but at least for me, it's not very clear.

The way my company uses Clickhouse is basically that we have one giant flat table, and have written our own abstraction layer on top of it based around "entities" which are functions of data in the underlying table, potentially adding in some window functions or joins against s3 or postgres depending on the entity being queried. Pretty much every query we write with Clickhouse tacks on a big "Group By All" at the end of it, because we are always trying to squash down the number of rows and aggregate as aggressively as possible.
I imagine we're not alone in this type of abstraction layer, and some type-safety would be very welcome there. I tried to build our system on top of Kysely (https://kysely.dev/) but the Clickhouse extension was not far along enough to make sense for our use-case. As such, we basically had to build our own parser that compiles down to sql, but there are many type-error edge cases, especially when we're joining in against data from S3 that could be CSV, Parquet, etc.
Side note: One of the things I love most about Clickhouse is how easy it is to combine data from multiple sources other than just the source database at query time. I imagine this makes the problem of building an ORM much harder as well, since you could need to build type-checking / ORM against sql queries to external databases, rather than to the source table itself

llm-scraper [1] does a decent job but it's still a bit fragile. The biggest problem I have is all the React CSS-in-JS libraries that use hashes in their class names, which the LLM isn't smart enough to ignore.

Project mention: Mathesar – An intuitive spreadsheet-like interface on Postgres | news.ycombinator.com | 2025-01-29Hi I'm one of the founders of Outerbase, just want to clarify a few things, seems like you might have some wrong information on Outerbase.
Big fan of Mathesar by the way!
1. We have a incredibly powerful CRUD editor on our table, in fact you can drag and drop and select multiple columns & rows, I haven't seen many other DB editors support this.
2. We allow you to pick foreign key constraints from a dropdown as well.
3. This is true.
4. Outerbase is open-source with more and more features heading into our core offering there. https://github.com/outerbase/studio

Project mention: I built a GH Action that uses AI to manually QA your PR using Magnitude/Claude | news.ycombinator.com | 2025-07-18
Got really inspired by Magnitude (https://github.com/magnitudedev/magnitude) recently and am tired of the manual process of QAing frontend features, so I decided to build a GH Action that does it for me. If you have a GH repo that generates preview links automatically, you just need to add this GH Action along with some env vars to your repo, and Magnitude will navigate to your link, login, find where in your app the changes were made, and QA them. Once it's done, it comments the results in your PR!
Hope folks find this useful! Would love to hear your comments
