WASM support

[genderev]

Does rust-libp2p support the wasm32-unknown-unknown target? I tried to compile the ping example with wasm-pack.

I thought the issue would be that the example relies on println! which is not available to the browser, but I actually got this error:

Compiling getrandom v0.2.3

error: the wasm32-unknown-unknown target is not supported by default, you may need to enable the "js" feature. For more information see: https://docs.rs/getrandom/#webassembly-support

You just need to add this in your Cargo.toml:
getrandom = { version = "0.2", features = ["js"] }

More info there:

• https://docs.rs/getrandom/0.2.3/getrandom/#webassembly-support
• https://docs.rs/getrandom/0.2.3/getrandom/#indirect-dependencies

You might need this in the future: #2143

Closing here. Let me know if you need any further help @genderev.

Thanks @fusetim for respoding!
