Run the Conflux-Rust node in Node.js. This is used for developing on the Conflux network, such as testing RPC dApps or contracts.
By now xcfx-node supports the following platforms:
- Linux (x86_64-unknown-linux-gnu)
- MacOS (aarch64-apple-darwin and x86_64-apple-darwin)
- Windows (x86_64-pc-windows-msvc)
If you want to run other platform or architecture, you can open an issue on GitHub
If you want to run a mainnet or testnet node, please refer to the Conflux documentation
