## Introduction
|
||||
|
||||
### Running against the Go daemon
|
||||
An implementation of [libp2p](https://libp2p.io/) in Nim. Also provides a Nim wrapper of the [Libp2p Go daemon](https://github.com/libp2p/go-libp2p).
|
||||
|
||||
An implementation of [libp2p](https://libp2p.io/) in Nim, as a wrapper of the [Libp2p Go daemon](https://github.com/libp2p/go-libp2p).
|
||||
## Project Status
|
||||
The current native Nim libp2p implementation support is experimental and shouldn't be relied on for production use. It is under active development and contributions are highly welcomed. :)
|
||||
|
||||
Note that you need Go 1.12+ for the below instructions to work!

|
||||
## Background
|
||||
libp2p is a networking stack and library modularized out of [The IPFS Project](https://github.com/ipfs/ipfs), and bundled separately for other tools to use.
|
||||
|
||||
libp2p is the product of a long and arduous quest of understanding; a deep dive into the internet's network stack and the peer-to-peer protocols from the past. Building large scale peer-to-peer systems has been complex and difficult in the last 15 years and libp2p is a way to fix that. It is a "network stack", a suite of networking protocols that cleanly separates concerns and enables sophisticated applications to only use the protocols they absolutely need, without giving up interoperability and upgradeability.
|
||||
|
||||
libp2p grew out of IPFS, but it is built so that lots of people can use it, for lots of different projects.
|
||||
|
||||
- Learn more about libp2p at [**libp2p.io**](https://libp2p.io) and follow our evolving documentation efforts at [**docs.libp2p.io**](https://docs.libp2p.io).
|
||||
- [Here](https://github.com/libp2p/libp2p#description) is an overview of libp2p and its implementations in other programming languages.

||||

|
||||
|
||||
This will output a peer ID such as `QmbmHfVvouKammmQDJck4hz33WvVktNEe7pasxz2HgseRu` which you can use in another instance to connect to it.
|
||||
#### Libp2p

||||
## API
|
||||
#### Utilities

|
||||

|
||||
|
||||
The native Nim libp2p implementation has finally arrived. Currently, it's support is experimental and shouldn't be relied on for production use. It is however under active development and we hope to achieve a reasonable level of stability in the upcoming months, as we will be integrating it across our own set of products, such as the Nim Beacon Chain.
|
||||
|
||||
### What to expect?
|
||||
Packages that exist in the original libp2p specs and are under active development:
|
||||
- libp2p-daemon
|
||||
- libp2p-webrtc-direct
|
||||
- libp2p-webrtc-star
|
||||
- libp2p-websockets
|
||||
- libp2p-spdy
|
||||
- libp2p-bootstrap
|
||||
- libp2p-kad-dht
|
||||
- libp2p-mdns
|
||||
- libp2p-webrtc-star
|
||||
- libp2p-delegated-content-routing
|
||||
- libp2p-delegated-peer-routing
|
||||
- libp2p-nat-mgnr
|
||||
- libp2p-utils
|
||||
|
||||
This implementation has a bare minimum set of components in order to provide a functional and interoperable libp2p stack. These are:
|
||||
** Note that the current stack reflects the minimal requirements for the upcoming Eth2 implementation.
|
||||
|
||||
- A TCP transport
|
||||
- multistream-select
|
||||
- Secio
|
||||
- Mplex
|
||||
- Identify
|
||||
- FloodSub
|
||||
- GossipSub
|
||||
|
||||
This stack reflects the minimal requirements for the upcoming Eth2 implementation.
|
||||
## Contribute
|
||||
The libp2p implementation in Nim is a work in progress. We welcome contributors to help out! Specifically, you can:
|
||||
- Go through the modules and **check out existing issues**. This would be especially useful for modules in active development. Some knowledge of IPFS/libp2p may be required, as well as the infrastructure behind it.
|
||||
- **Perform code reviews**. Feel free to let us know if you found anything that can a) speed up the project development b) ensure better quality and c) reduce possible future bugs.
|
||||
- **Add tests**. Help nim-libp2p to be more robust by adding more tests to the [tests folder](https://github.com/status-im/nim-libp2p/tree/master/tests).

# Introduction
|
||||
This is a libp2p-backed daemon wrapping the functionalities of go-libp2p for use in Nim. <br>
|
||||
For more information about the go daemon, check out [this repository](https://github.com/libp2p/go-libp2p-daemon).
|
||||
|
||||
# Installation
|
||||
```sh
|
||||
# clone and install dependencies
|
||||
git clone https://github.com/status-im/nim-libp2p
|
||||
cd nim-libp2p
|
||||
nimble install
|
||||
|
||||
# perform unit tests
|
||||
nimble test
|
||||
|
||||
# update the git submodule to install the go daemon
|
||||
git submodule update --init --recursive
|
||||
go version
|
||||
git clone https://github.com/libp2p/go-libp2p-daemon
|
||||
cd go-libp2p-daemon
|
||||
git checkout v0.0.1
|
||||
go install ./...
|
||||
cd ..
|
||||
```
|
||||
|
||||
# Usage
|
||||
|
||||
## Example
|
||||
Examples can be found in the [examples folder](https://github.com/status-im/nim-libp2p/tree/readme/examples/go-daemon)
|
||||
|
||||
## Getting Started
|
||||
Try out the chat example. Full code can be found [here](https://github.com/status-im/nim-libp2p/blob/master/examples/chat.nim):
|
||||
|
||||
```bash
|
||||
nim c -r --threads:on examples\chat.nim
|
||||
```
|
||||
|
||||
This will output a peer ID such as `QmbmHfVvouKammmQDJck4hz33WvVktNEe7pasxz2HgseRu` which you can use in another instance to connect to it.
|
||||
|
||||
```bash
|
||||
./example/chat
|
||||
/connect QmbmHfVvouKammmQDJck4hz33WvVktNEe7pasxz2HgseRu
|
||||
```
|
||||
|
||||
You can now chat between the instances!
