# The libp2p 'host'
|
|
|
|
For most applications, the host is the basic building block you'll need to get started. This guide will show how to construct and use a simple host on one side, and a more fully-featured host on the other.
|
|
|
|
The host is an abstraction that manages services on top of a swarm. It provides a clean interface to connect to a service on a given remote peer.
|
|
|
|
If you want to create a host with a default configuration refer to the example in `./host.go`
|
|
|
|
If you want more control over the configuration, you can specify some options to the constructor. For a full list of all the configuration supported by the constructor [see the different options in the docs](https://godoc.org/github.com/libp2p/go-libp2p).
|
|
|
|
In `./host.go` we set a number of useful options like a custom ID and enable routing. This will improve discoverability and reachability of the peer on NAT'ed environments.
|
|
|
|
In future guides we will go over ways to use hosts, configure them differently (hint: there are a huge number of ways to set these up), and interesting ways to apply this technology to various applications you might want to build.
|
|
|
|
To see this code all put together, take a look at [host.go](host.go).
