Console Mode
This page describes Elld Javascript console

Elld comes with a Javascript environment designed to allow users interact with the client, blockchain state and the network. With the console, you will be able to write and execute complex scripts in Javascript.

Starting the Elld in console mode is simple. You only need to use the console command instead of the start command.
elld console -a "0.0.0.0:9000"
The command above will start the client and immediately present you with a prompt to type arbitrary Javascript expressions expressions and call in-built functions.

Elld provides the ability to start a console that attaches to a remote node. Using attach command instead of console starts the console in attach mode.
In attach mode, only the console and a RPC client is enabled. You can call most functions that are available in the un-attached mode.
elld attach
The command above will attach to the local Elld instance running on the default RPC address 127.0.0.1:8999. Use --rpcaddress to specify a different address.

The console environment includes in-built, helper methods for interacting with the client, blockchain state and the network. These methods are categorized into namespaces according to their functions and similarities.
Namespace
Description
global
Includes convenience methods that are commonly used.
admin
Perform administrative functions.
personal
Includes methods that access or interact with node's accounts.
ell
Includes methods that access and interact with an accounts balance.
rpc
Includes methods that starts, stops and checks the status of the RPC server.
_system
Includes non-user friendly methods that are directly bound to native functions.

RPC namespaces provides access to services offered by the RPC server. They are not available in the console until the RPC server starts to run. These are the namespaces:
Namespace
Description
state
Access the blockchain state (e.g blocks, branches etc)
ell
Access account balance and send balance.
node
Includes methods to access client information (e.g configs, sync state etc).
pool
Access the transaction pool.
miner
Manage the CPU miner.
personal
Includes methods that access or interact with node's accounts.
admin
Perform administrative functions
net
Manage and access the clients peers and network functions.
logger
Update log level (useful for debugging)

By default, RPC namespaces will not be accessible in the console when the RPC server is not turned on. To turn on the RPC server within the console, call the rpc.start method:
> rpc.start()
Which should produce the log output below:
> INFO[0008] RPC service started Address="127.0.0.1:8999"
