"Struggling to configure types proxy – any tips or step-by-step guide?"
Hey folks,
So I’ve been trying to configure types proxy for like, forever, and it’s driving me nuts. Every time I think I got it right, something breaks.
Anyone else been through this?
Like, what’s the *actual* best way to configure types proxy without pulling your hair out? I’ve seen some docs, but they’re either too vague or assume you’re a wizard.
Common issues I hit:
- Weird type errors after setup
- Config just... not applying?
- Performance tanks for no reason
If you’ve got a solid step-by-step or just some "oh yeah, don’t do *that*" tips, pls share.
Or is it just me? 😅
(Also, if there’s a *proper* way to configure types proxy for optimal speed, spill the beans!)
Thanks in advance! 🚀
Oh man, I feel you! Configuring types proxy can be a nightmare if the docs are outdated or too complex.
One thing that saved me was using `ts-proxy-generator`—it auto-generates a lot of the boilerplate. Also, double-check your `tsconfig.json` because sometimes the paths get messed up.
For performance, avoid nesting proxies too deep. It *will* slow things down.
Here’s a decent guide I found: [link to a relevant blog]. Hope it helps!
Been there! The key is to start small. Don’t try to configure types proxy for everything at once.
First, get the basic types working, then layer in the proxies. And yeah, those weird type errors usually mean your generics are off.
Tool rec: `type-fest` has some handy utilities for this. Also, maybe share your config? Might spot the issue.
Lol it’s not just you. I spent a whole weekend on this.
Biggest "aha" moment: Make sure your proxy types are *assignable* to the original. If not, things explode in weird ways.
Also, `@types/proxy-helper` is a lifesaver. Not perfect, but better than nothing.
Speed tip: Cache your proxies if you can. Recreating them on the fly kills perf.
Ugh, the "config not applying" thing drove me nuts too. Turns out, sometimes the order of operations matters.
Try wrapping your proxy config in a function and calling it *after* all types are loaded. Sounds dumb, but it worked for me.
Also, `ts-morph` can help debug this stuff—lets you inspect the AST and see where things go wrong.
Wow, thanks everyone! Didn’t expect so many replies.
Tried the `ts-proxy-generator` and it *mostly* worked, but now I’m getting some weird "Type instantiation is excessively deep" errors.
Anyone seen that before? Is it just a recursion thing, or am I missing something?
Also, gonna check out that YouTube tutorial—docs are indeed trash lol.
Thanks again! 🙌
If you’re hitting performance issues, check if you’re accidentally creating recursive proxies. That’s a common pitfall.
For a step-by-step, I followed this [YouTube tutorial] and it was way clearer than the docs.
And yeah, the type errors are usually a sign you’re missing a conditional type somewhere. `extends` is your friend!
Honestly? The docs for configure types proxy are trash.
What worked for me: Copy-pasting a working example from GitHub and tweaking it. Here’s a gist: [link].
Also, enable `strictNullChecks` if you haven’t. It’ll catch a ton of issues early.
Pro tip: Use `Proxy` from `es6` sparingly. It’s powerful but easy to overuse.
For type safety, I’d recommend `io-ts` or `zod` to validate before proxying. Adds a step but saves headaches later.
And yeah, share your config—might be something obvious we can spot.
Speed tip: If your types proxy is slow, try memoizing the proxy creation.
Also, `tsc --traceResolution` can help figure out why some types aren’t being picked up.
And +1 to `type-fest`—super handy for this stuff.
