Warning: this tool is experimental. It should work for GNU/Linux and hopefully on Mac OS.

ethnode is a zero configuration tool to run a local Ethereum node. It supports both Parity and Geth.

Try it out:

npm install -g ethnode
ethnode

ethnode automatically:

• downloads the latest stable version of geth or parity
• configures geth or parity to run in a single node network using the clique (Geth) or InstantSeal (Parity) consensus engine (transactions are processed instantly)
• provides 10 unlocked accounts with 100ETH each
• enables all RPC endpoints (personal, db, eth, net, web3, debug and more)
• allows CORS from any domain (so you can use it with remix)

By default ethnode runs geth. If you want to run parity type ethnode parity.

Parity has a nice feature to run it as a private development chain (aka test RPC).

While testing it, I run into some problems, like:

• address management
• outdated genesis file
• the default configuration (--config dev) doesn't:
  • open up CORS
  • unlock the test keys

More or less for the same reasons mentioned above.

Ganache sometimes is not enough.
