examples

To run the examples, you will need to set the following config variables:

1. INFURA_PROJECT_ID : an PROJECT ID (formerly called API KEY) from https://infura.io
2. ETH_PRIVATE_KEY : a private key of an Ethereum wallet with some ETH in it

These can be sat as environment variables or in a config.json file placed in this directory.

You can use 00.setup.js to create the config.json file, however since the INFURA_PROJECT_ID cannot be created pragmatically, you will first need to obtain it by following the 3 easy steps here: https://ethereumico.io/knowledge-base/infura-api-key-guide

NOTE: the API KEY mentioned in the instructions has been renamed to PROJECT ID.

Once you obtain the INFURA_PROJECT_ID you can then run:

node 00.setup.js YOUR_INFURA_PROJECT_ID

or simply

./00.setup.js YOUR_INFURA_PROJECT_ID

This will:

1. generate a new Ethereum wallet on ropsten
2. pre-load it with Eth (at least 1 Eth)
3. save both the wallets private key and passed in INFURA_PROJECT_ID into ./config.json file in this directory.

NOTE: All example files are marked as executables and contain a shebang line which will caused them to be executed by node if called directly. Fox example the following should work if you have previously ran the ./00.setup.js script:

./01.register.js

or if you prefer, you can provide the required config vars on command line:

INFURA_PROJECT_ID=YOUR_ID ETH_PRIVATE_KEY=YORU_KEY ./01.register.js

You need to run ./01.register.js exactly once before attempting any other examples.

For the examples which required ether balance, you will also need to call ./02.deposit.js.
