How can we configure a single crate that supports both native (with gossipsub) and WASM (with gossipsub) without getrandom conflicts?

[fgtest1]

HI
I have opened a Q/A for reference #6244 and still not able to solve the dual compilation and waiting for assistance on this matter.

When will libp2p v0.57 be released?
#6244

“How can we configure a single crate that supports both native (with gossipsub) and WASM (with gossipsub) without getrandom conflicts?”

We maintain a single crate that must support:
Native: TCP/WebSocket + gossipsub
WASM: WebRTC + gossipsub

We’ve solved WASM compilation, but native builds fail due to getrandom v0.3.4 requiring wasm_js feature even on native.

What’s the official recommended way to configure Cargo.toml for dual-target libp2p with gossipsub?
We’re using a local libp2p fork (main branch) and need a stable, maintainable setup.

I appreciate your input
Thanks

If the following doesn't help you fix the issue, then please open a repo with a minimal example.

[package]
name = "foo"
version = "0.1.0"
edition = "2024"

[dependencies]
libp2p = { version = "0.56.0", features = ["gossipsub"] }

# Native
[target.'cfg(not(target_arch = "wasm32"))'.dependencies]
libp2p = { version = "0.56.0", features = ["tokio", "dns", "tcp", "websocket"] }

# WASM (browsers)
[target.'cfg(target_arch = "wasm32")'.dependencies]
libp2p = { version = "0.56.0", features = ["wasm-bindgen", "webrtc-websys"] }
getrandom = { version = "0.3.4", features = ["wasm_js"] }
getrandom_02 = { package = "getrandom", version = "0.2.17", features = ["js"] }

After days again.... of config battle, we finally compiled native and wasm on same crate..
Full dual-target support achieved.

single crate with requirements for native + WASM
-getrandom
-gossipsub

.cargo/config.toml
[target.wasm32-unknown-unknown]
** nothing **

This simple line compiled native and WASM (with getrandom v0.2.17 and v0.3.4....!!)

#.. WASM
[target.'cfg(target_arch = "wasm32")'.dependencies]
getrandom = { version = "0.2.17", features = ["js"] }

*after compilation we can clearly see the tree dependency
native
getrandom v0.2.17
getrandom v0.3.4

WASM
getrandom v0.2.17
getrandom v0.3.4 ((NOTHING empty ))

Documentation and guidance needs a serious review, the "wasm_js" and .cargo/config.toml is NOT accurate.
The "wasm_js" leaded us to spend countless hours of configuration...

But now we got something working.

Thanks
