ApiPromise Examples
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.
Prerequisites
For the following examples, you need a local node. It is usually convenient testing with:
substrate --dev
Running the examples
From each folder, run yarn to install the required dependencies and then run yarn start to execute the example against the running node.
Development accounts
Some of the examples use the following accounts:
- Alice:
5GoKvZWG5ZPYL1WUovuHW3zJBWBP5eT8CbqjdRY4Q6iMaDtZ - Bob:
5Gw3s7q4QLkSWwknsiPtjujPv3XM4Trxi5d4PgKMMk3gfGTE
Those accounts are easy to add if you don't have/see them. The seed of Alice's account is Alice␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣ and the seed of Bob is... well you guess...
NOTE: Note the spaces padding Alice's key up to 32 chars.
