* WIP backend trait * WIP converting higher level stuff to using Backend impl * more implementing new backend trait, mainly storage focused * Get core code compiling with new backend bits * subxt crate checks passing * fix tests * cargo fmt * clippy/fixes * merging and other fixes * fix test * fix lightclient code * Fix some broken doc links * another book link fix * fix broken test when moving default_rpc_client * fix dry_run test * fix more tests; lightclient and wasm * fix wasm tests * fix some doc examples * use next() instead of next_item() * missing next_item() -> next()s * move legacy RPc methods to LegacyRpcMethods type to host generic param instead of RpcClient * standardise on all RpcClient types prefixed with Rpc, and 'raw' trait types prefixed with RawRpc so it's less ocnfusing which is which * rename fixes * doc fixes * Add back system_dryRun RPC method and rename tx.dry_run() to tx.validate(), to signal that the calls are different * Add a test that we return the correct extrinsic hash from submit() * add TransactionValid details back, and protect against out of range bytes * add test for decoding transaction validation from empty bytes * fix clippy warning
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.
