Vite 8.0 Is Out

For anyone that doesn't know: With sqlite you can serialize the db to a buffer and create a "new" db from that buffer with just `new Datebase()`. Just run the migrations once on test initialization, serialize that migrated db and reuse it instantly for each test for amazing test isolation.

Yea, cypress has this in their anti-patterns:

Dangling state is useful for debugging when the test fails, you don't want to clean that up.

This has been super useful practice in my experience. I really like to be able to run tests regardless of my application state. It's faster and over time it helps you hit and fixup various issues that you only encounter after you fill the database with enough data.

This is because the kotlin compiler is not written in the way people write fast compilers. It has almost no backend to speak of (if you are targeting the jvm), and yet it can be slower at compilation than gcc and clang when optimizing.

Modern fast compilers follow a sort of emerging pattern where AST nodes are identified by integers, and stored in a standard traversal order in a flat array. This makes extremely efficient use of cache when performing repeated operations on the AST. The Carbon, Zig, and Jai compiler frontends are all written this way. The kotlin compiler is written in a more object oriented and functional style that involves a lot more pointer chasing and far less data-dense structures.

Then, if run on a non-graal environment, you also have to pay for the interpreter and JIT warmup, which for short-lived tasks represents nontrivial overhead.

But unlike header inclusion or templates, which are language level features that have major effects on compilation time, I don't think kotlin the language is inherently slow to compile.

Compare this to essentially any modern business app, the product being sold has very little relationship with CPU cycles, or the CPU cycles are SO cheap relative to what you're getting paid, no one cares to optimize.

It all slowly adds up where you think a simple $10 VPS with 2 gigs of ram is enough but it's not, especially if you want a team of 10-30ish to work sporadically within the same box.

There can be a lot of major wins by rewriting these programs in more efficient languages like Go or Rust. It would make self hosting more maintainable and break away from the consulting class that often has worse solutions at way higher prices (for an example, one consulting group sells software similar to postiz but for $2k/month).

For a server built in the cloud those cycles could actually be taken up by other things, freeing the system and bringing costs down.

For a client computer running electron, as long as the user doesn't have so many electro apps open that their computer slows down noticeably, that inefficency might not matter that much.

Another aspect is that the devices get cheaper and faster so today's slow electron app might run fine on a system that is a few years away, and that capacity was never going to be taken up by anything else on the end user's device.

at least 100x slower than it needs to be?

You're not actually suggesting that technology can't evolve are you? Especially one whose original design goals were to process basic forms and are now being used to build full-blown apps?

It's absolutely wild to me that with everything that has happened in the last 2 decades with regard to the web there are still people who refuse to accept that it's changed. We are building far bigger and more complex applications with JavaScript. What would you propose instead?

Was it? Have you forgotten namespaces and enums?

That's no less a build step than concating, bundling, minifying, etc. When people say "I'm against processing code before deploying it to a web site" but then also say "TypeScript is okay though" or "JSX is okay though," all they're really saying is "I like some build steps but not others." Which is fine! Just say that!

JSX is a nice server side templating language. There a lot of people who aren't dependency conscious, and a lot of people who love react, and there is quite a bit of overlap in those two groups. I've used bun + preact_render_to_string for server side JSX templates before and it was nice. When I did it seemed that bun somewhat embraced react, and I could imagine react being the path of least resistance to server-side JSX there for some of the folks in the aforementioned groups.

5 or so years ago, Next was a pretty solid option to quickly build up a non SPA, when combined with the static export function. It wasn't ideal, but it worked and came batteries included. Over time it's become more bloated, more complicated, and focused on features that benefit from Vercel's hosting – and static builds can't take advantage of them.

These newer features seem of limited benefit, to me, for even SPAs. Why is there still not a first class way of referencing API routes in the client code that provides typing? Once you reach even medium scale, it becomes a mess of inteprolated string paths and manually added shared response types.

And to sell Vercel on top.

Fetch index.html -> Fetch JS bundle -> Evaluate -> Fetch /users/me

You do:

Fetch index.html (your page is rendered at this point) -> rehydrate with client side JS for interactivity in the background

It's a pretty smart solution I think, and many people are still sleeping on the whole SSR topic.

Imagine a page that loads html during the first load, and then performs client-side routing during subsequent navigations. Is it an SPA? Is it not an SPA?

I checked sitecore cloud to have special integration for nextjs and reactjs. But it also support vanilla js as well.

Are there really anyone who is exclusive to nextjs?

There are several much better options right now. My favourite is Tanstack Start. No magice, great DX

The LLM generated vite config is 20 lines

> Unfortunately for Bun, if they are forced to help Anthropic more than they can focus on OSS

Curious: is that speculation, or based on observation?

Do you know what the status is on using Rolldown as a crate for rust usage? At the moment most rust projects use SWC but afaik its bundler is depreciated. I usually just call into Deno for builds but would be nice to have it all purely in Rust.

https://github.com/oxc-project/oxc/issues/6073

    {
        // ...
        "imports": {
            "#assets/*": "./src/assets/*",
            "#/*": "./src/*"
        },
        // ...
    }

    import router from "#/router/index"

Now, imports from e.g. "#assets/main.css" work, so I could work around this issue - but this is what I keep experiencing: the native variant usually kinda works except for the most common use case, which is made unnecessarily awkward. For a long time this is what ESM used to feel like, and IMO it still does in places (e.g. directory imports not working is a shame).

Another instance is the use of rollupOptions.output.manualChunks that now has to be rewritten, maybe that would be less frustrating to fathom.

Fast all the way down, especially when coupled with REPL tooling.
