Getting Started

Run npm run start

Build and Test

• Run npm run build for generate bundle
• Run docker build . -t driver-did-ev for generate docker image
• Run docker run -p 8080:8000 -e NODE_HOST=[YOUR_BLOCKCHAIN_NODE_RPC] -e ADDRESS_IM=[YOUR_SMARTCONTRACT_ADDRESS] -d driver-did-evfor run container

driver-did-ev accepts the following environment variables:

Key	Description	Default	Notes
NODE_HOST	RPC node url	(mandatory)
ADDRESS_IM	Address of the Identity Manager contract	(mandatory)
HEADERS	Additional HTTP headers (in JSON format) for JSON-RPC calls to node, such as authentication	No headers
FIND_EVENTS	Use Ethereum events as a source for getting the authorized keys.	true
KEYS	Use an explicit list of keys as a source for getting the authorized keys. E.g.: ['0x2FD3a895C728652FFe586b0B9e07B47edfC6e3FD']	[]
BASE_BLOCKS	Minimum value for fromBlock.	30000000	Only used when findEvents is true.
LAST_BLOCKS	Last blocks to be taken from toBlock.	0	Only used when findEvents is true.
BUFFER_SIZE	Size of the slices in the event searching. Use greater values to search more efficiently, use lower values to avoid possible timeout problems.	100000	Only used when findEvents is true.
START_BLOCK_MARGIN	Web3JS or Besu seem to have a bug where filtering events sometimes ignores events emitted in the early blocks. This setting can be used to work around the issue by starting the filtering on an earlier block number.	100000	Only used when findEvents is true.
