nextjs-tailwind-ionic-capacitor-st VS swc

wow, that's a weird limitation.

The README says: "SSR is currently disabled for the Next.js app as the app will be fully client-side rendered for iOS and Android. This is a limitation we are working to address in a future update."

I guess it's because CapacitorJS pre-bundles the entire PWA for the App Stores:

"Of course, you also could load the app completely remotely by changing the server.url configuration for Capacitor to point to your SSR'ed Next.js app, but that has other challenges such as App Store approval if the app doesn't check the boxes for Apple to qualify it as an app that has enough native integration (at that point this is on you, not Capacitor)"

But I don't understand why SSR would be disabled for the NextJS PWA on the web?

Maybe Max Lynch aka. @mlynch aka. @yesimahuman could provide some insight here.

Agreed! Next.js works great with this model! I’d recommend Capacitor over Cordova (similar but more modern). Here’s an example: https://github.com/mlynch/nextjs-tailwind-ionic-capacitor-st...

First, we switched the default compiler for new projects from Babel to SWC (Speedy Web Compiler). SWC is dramatically faster than Babel and requires zero configuration. We’ll continue to support Babel in any project currently using it.

SWC

As the reference explains “**SWC** (Speedy Web Compiler) is an extensible Rust-based platform that can be used for both compilation and bundling. Using SWC with Nest CLI is a great and simple way to significantly speed up your development process.”

This is specifically about breaking the myth that performing expensive self-contained operations (e.g, parsing GraphQL) in a native extension (C, Rust, etc.) is always faster than the interpreted language.

The JS ecosystem has the same problem, people think rewriting everything in Rust will be a magic fix. In practice, there's always the problem highlighted in the post (transitioning is expensive, causes optimization bailouts), as well as the cost of actually getting the results back into Node-land. This is why SWC abandoned the JS API for writing plugins - constantly bouncing back and forth while traversing AST nodes was even slower than Babel (e.g https://github.com/swc-project/swc/issues/1392#issuecomment-...)

Why Speedy Web Compiler ?

FTA is a TypeScript static analysis tool built on the speedy foundations of swc. FTA is fast; capable of analyzing more than 150 files per second on typical hardware, it offers a powerful addition to your code quality toolkit.

Very cool! I'm curious, is this intended for dev tooling?

For example, I could see this (or something similar) being useful as the engine for a typescript language server that would be faster than the standard one

But if it's not aimed at 1:1 with tsc, would it be intended more for something like swc[1]?

Or what would you expect people to use this for, besides just being a cool project to learn from?

This is... good news, but I still cannot fathom using the default Typescript compiler for regular development. Seriously, leave the type-checking to your IDE and CICD chain, and switch to using tsx (https://www.npmjs.com/package/tsx) or swc (https://swc.rs/) and you will _immediately_ notice the difference in speed and productivity.
