package client
|
|
|
|
/*
|
|
The client package provides a general purpose interface (Client) for connecting
|
|
to a tendermint node, as well as higher-level functionality.
|
|
|
|
The main implementation for production code is client.HTTP, which
|
|
connects via http to the jsonrpc interface of the tendermint node.
|
|
|
|
For connecting to a node running in the same process (eg. when
|
|
compiling the abci app in the same process), you can use the client.Local
|
|
implementation.
|
|
|
|
For mocking out server responses during testing to see behavior for
|
|
arbitrary return values, use the mock package.
|
|
|
|
In addition to the Client interface, which should be used externally
|
|
for maximum flexibility and testability, and two implementations,
|
|
this package also provides helper functions that work on any Client
|
|
implementation.
