# subxt ·  [](https://crates.io/crates/substrate-subxt) [](https://docs.rs/substrate-subxt)
|
|
|
|
A library to **sub**mit e**xt**rinsics to a [substrate](https://github.com/paritytech/substrate) node via RPC.
|
|
|
|
## Usage
|
|
|
|
See [examples](./examples).
|
|
|
|
## Integration Testing
|
|
|
|
Most tests require a running substrate node to communicate with. This is done by spawning an instance of the
|
|
substrate node per test. It requires an executable binary `substrate` at [`v3.0.0`](https://github.com/paritytech/substrate/releases/tag/v3.0.0) on your path.
|
|
|
|
This can be done by downloading the prebuilt binary:
|
|
|
|
```bash
|
|
curl "https://releases.parity.io/substrate/x86_64-debian:stretch/v3.0.0/substrate/substrate" --output substrate --location
|
|
chmod +x ./substrate
|
|
mv substrate ~/.local/bin
|
|
```
|
|
|
|
Or installed from source via cargo:
|
|
|
|
```bash
|
|
cargo install --git https://github.com/paritytech/substrate node-cli --tag=v3.0.0 --force
|
|
```
|
|
|
|
|
|
|
|
|
|
**Alternatives**
|
|
|
|
[substrate-api-client](https://github.com/scs/substrate-api-client) provides similar functionality.
|
|
|
|
## Subxt Client
|
|
By default the client builder will connect to a full node via rpc. The `subxt-client` helps
|
|
embedding a light client directly. It can also be used to embed a full node. This is especially
|
|
useful for testing and ci.
