wasm-example

This is a small WASM app using the Yew UI framework to showcase how to use Subxt's features in a WASM environment.

To run the app locally we first install Trunk, a WASM bundler:

cargo install --locked trunk

You need to have a local polkadot/substrate node with it's JSON-RPC HTTP server running at 127.0.0.1:9933 in order for the examples to be working. If you have a polkadot binary already, running this should be sufficient:

polkadot --dev

Then, in another terminal, run the app locally with:

trunk serve --open

signing example

For the signing example, we use the @polkadot/extension-dapp NPM package to talk to wallets loaded as browser extensions. In order to sign and submit the transaction using the polkadot --dev node we spawned above, you'll need to create a dev account in your wallet of choice. Use the recovery phrase bottom drive obey lake curtain smoke basket hold race lonely fit walk and the derivation path //Alice to create a dev account that can be used.
