Here you will find a list of examples that takes you through the basics of connecting to a local node, retrieving data from the Node and chain and execute transactions on the chain. It uses the ApiRx interface.
For the following examples, you need a local node. It is usually convenient testing with:
substrate --dev
Some of the examples use the following accounts:

Alice..............
and the seed of Bob is... well you guess.
NOTE: Note the spaces padding Alice's key up to 32 chars.
