Parameters to loadScript with no absolute path will be understood relative to this directory. There are some limitations though:. This library is auto-loaded into the console. It implements setInterval , clearInterval , setTimeout , clearTimeout you may be used to using in browser windows. It also provides implementation for admin.

Web3 can be extended and used to consume these additional APIs. The different functions are split into multiple smaller logically grouped APIs. The admin API gives you access to several non-standard RPC methods, which will allow you to have a fine grained control over your Geth instance, including but not limited to network peer and RPC endpoint management.
The addPeer administrative method requests adding a new remote node to the list of tracked static nodes. The node will try to maintain connectivity to these nodes at all times, reconnecting every once in a while if the remote connection goes down. The method accepts a single argument, the enode URL of the remote peer to start tracking and returns a BOOL indicating whether the peer was accepted for tracking or some error occurred.
The datadir administrative property can be queried for the absolute path the running Geth node currently uses to store all its databases. The nodeInfo administrative property can be queried for all the information known about the running Geth node at the networking granularity. The peers administrative property can be queried for all the information known about the connected remote nodes at the networking granularity.
The method accepts an absolute path to the Solidity compiler to use specifying a relative path would depend on the current — to the user unknown — working directory of Geth , and returns the version string reported by solc --version. All the parameters are optional:. Please note, only one HTTP endpoint is allowed to be active at any time. Please note, only one WebSocket endpoint is allowed to be active at any time. As the node can only have a single HTTP endpoint running, this method takes no parameters, returning a boolean whether the endpoint was closed or not.
As the node can only have a single WebSocket endpoint running, this method takes no parameters, returning a boolean whether the endpoint was closed or not. The debug API gives you access to several non-standard RPC methods, which will allow you to inspect, debug and set certain debugging flags during runtime.
Sets the logging backtrace location. When a backtrace location is set and a log message is emitted at that location, the stack of the goroutine executing the log statement will be printed to stderr. Turns on block profiling for the given duration and writes profile data to disk. It uses a profile rate of 1 for most accurate information. Retrieves the state that corresponds to the block number and returns a list of accounts including storage and code.
Sets the current head of the local chain by block number. Note , this is a destructive action and may severely damage your chain. Use with extreme caution. A non-zero rate enables block profiling, setting it to zero stops the profile. Returns a printed representation of the stacks of all goroutines. Note that the web3 wrapper for this method takes care of the printing and does not return the string.
The traceBlock method will return a full stack trace of all invoked opcodes of all transaction that were included included in this block. Note , the parent of this block must be present or it will fail. The traceTransaction debugging method will attempt to run the transaction in the exact same manner as it was executed on the network. It will replay any transaction that may have been executed prior to this one before it will finally attempt to execute the transaction that corresponds to the given hash.
