Transform Performance Slow

[timoxley]

I have a small vite/vitest application with a handful of tests. The tests take a long time to cold-start and it appears they are getting slowed down by the typia transform: ~15 seconds for ~15 files.

Is there something that can be configured to make it transform faster, e.g. caching, parallelism or something, or is this perhaps a limitation of esbuild/tsc/vite? Any suggestions or additional information I can provide?

       

AFAICT I'm on the latest version of all relevant packages.

    "typescript": "^5.6.2",
    "typia": "^6.11.0",
    "vite": "^5.4.4",
    "vite-plugin-inspect": "^0.8.7",
    "vitest": "^2.1.1"

I think this might be more relevant for unplugin-typia. ryoppippi/unplugin-typia#334

[timoxley]

you know what, I think it may be typia itself, I don't know?

I created a kind of subset of my setup in the typia playground

When I import this file and build it with my app, via vite, it takes ~1.5 seconds. ~1.5s is fine if this was the only file, but in my full (simple) app these add up to about 30s of additional build time 🎻😿. This file has no external deps (other than typia), so I'm starting to doubt my suspicion that it's an issue with the way the unplugin plugin sets up the ts context per-file (see issue I opened on the plugin).

What do you think @samchon, @ryoppippi?

@timoxley Wait, is unplugin-typia process every single file?
unplugin-typia skips processing a file without a keyword typia

It's processing all the files with the typia keyword, that seems to be working correctly.

Yeah, so idk why it slows so much.

Anyway, I reopen ryoppippi/unplugin-typia#334 again. In this issue, we discuss typia's transformer itself. We'll discuss unplugin-typia's improvement in another issue!
