ethnode, run an Ethereum node for test and development

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.

FAQ

Why not just running parity --config dev?

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• outdated genesis file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

Why not just running geth --dev?

More or less for the same reasons mentioned above.

Why not ganache-cli?

Ganache sometimes is not enough.
