## Configuration |
||||
|
||||
Configuration for parity URLs can be provided with the following mix |
||||
config: |
||||
|
||||
```elixir |
||||
config :ethereum_jsonrpc, |
||||
url: "https://sokol.poa.network", |
||||
trace_url: "https://sokol-trace.poa.network", |
||||
http: [recv_timeout: 60_000, timeout: 60_000, hackney: [pool: :ethereum_jsonrpc]] |
||||
``` |
||||
|
||||
Note: the tracing node URL is provided separately from `:url`, |
||||
via `:trace_url`. The trace URL and is used for |
||||
`fetch_internal_transactions`, which is only a supported method on |
||||
tracing nodes. The `:http` option is passed directly to the HTTP |
||||
library (`HTTPoison`), which forwards the options down to `:hackney`. |
||||
|
||||
## Installation |
||||
|
||||
The OTP application `:ethereum_jsonrpc` can be used in other umbrella |
||||
OTP applications by adding `ethereum_jsonrpc` to your list of |
||||
dependencies in `mix.exs`: |
||||
|
||||
```elixir |
||||
def deps do |
||||
[ |
||||
{:ethereum_jsonrpc, in_umbrella: true} |
||||
] |

end |

Default options are pulled from application config under the |

|
||||
* `:debug_logs` - When `true` logs verbose index progress. Defaults `#{@debug_logs}`. |
||||
* `:blocks_batch_size` - The number of blocks to request in one call to the JSONRPC. Defaults to |
||||
`#{@blocks_batch_size}`. Block requests also include the transactions for those blocks. *These transactions |
||||
are not paginated.* |
||||
* `:blocks_concurrency` - The number of concurrent requests of `:blocks_batch_size` to allow against the JSONRPC. |
||||
Defaults to #{@blocks_concurrency}. So upto `blocks_concurrency * block_batch_size` (defaults to |
||||
`#{@blocks_concurrency * @blocks_batch_size}`) blocks can be requested from the JSONRPC at once over all |
||||
connections. |
||||
* `:block_rate` - The millisecond rate new blocks are published at. Defaults to `#{@block_rate}` milliseconds. |
||||
* `:internal transactions_batch_size` - The number of transaction hashes to request internal transactions for |
||||
in one call to the JSONRPC. Defaults to `#{@internal_transactions_batch_size}`. |
||||
* `:internal transactions_concurrency` - The number of concurrent requests of `:internal transactions_batch_size` to |
||||
allow against the JSONRPC **for each block range**. Defaults to `#{@internal_transactions_concurrency}`. So upto |
||||
`block_concurrency * internal_transactions_batch_size * internal transactions_concurrency` (defaults to |
||||
`#{@blocks_concurrency * @internal_transactions_concurrency * @internal_transactions_batch_size}`) transactions |
||||
can be requesting their internal transactions can be requested from the JSONRPC at once over all connections. |
||||
*The internal transactions for individual transactions cannot be paginated, so the total number of internal |
||||
transactions that could be produced is unknown.* |
||||
* `:receipts_batch_size` - The number of receipts to request in one call to the JSONRPC. Defaults to |
||||
`#{@receipts_batch_size}`. Receipt requests also include the logs for when the transaction was collated into the |
||||
block. *These logs are not paginated.* |
||||
* `:receipts_concurrency` - The number of concurrent requests of `:receipts_batch_size` to allow against the JSONRPC |
||||
**for each block range**. Defaults to `#{@receipts_concurrency}`. So upto |
||||
`block_concurrency * receipts_batch_size * receipts_concurrency` (defaults to |
||||
`#{@blocks_concurrency * @receipts_concurrency * @receipts_batch_size}`) receipts can be requested from the |
