missing crate node-primitives on crates.io for 2.0.0-alpha.5 about substrate-node-template HOT 5 CLOSED

same for substrate-test-runtime-client

from substrate-node-template.

The node_primitives crate is for use specifically in the demonstration node that lives in the Substrate repo. This is evidenced by the fact that it lives in bin/node/pirmitives. The two imports you mentioned, AccountId and Signature are both type aliases to things that are in the library part of the Substrate repo and are published on crates.io.

This node template, makes the same type aliases directly in the runtime's lib.rs (AccountId, Signature). If you're basing your node on this template, you can use those type aliases directly, or if you like having them in a separate crate, you can move them to their own crate. You could call that crate node-primitives and let it's context make it clear what node they are for or you could give it a name like brenzis-node-primitives. You can see polkadot also [follows this pattern](https://github.com/paritytech/polkadot/tree/master/primitives

ok. but how about substrate-test-runtime-client? Where should I get use test_client::AccountKeyring; from? From sp_keyring I guess?

from substrate-node-template.

TBH, I'm not nearly as familiar with that one. I guess maybe from here https://substrate.dev/rustdocs/master/sp_keyring/test/index.html

@gnunicorn is that right?

@brenzi node-* are meant for the substrate-node-default-implementation only, are very opinionated and not suitable for reusability but part of the executable only. We are still discussing whether we eventually publish them on crates.io but for the time being (and probably 2.0 release), these won't be published there (as we can't and won't give the same semver stability guarantees for the binary).

That said, what you are asking for is literally something you can (and should) define yourself:

use sp_runtime::{
	generic, traits::{Verify, IdentifyAccount}, MultiSignature
};

pub type Signature = MultiSignature;

pub type AccountId = <<Signature as Verify>::Signer as IdentifyAccount>::AccountId;
