LBRY Hub

A hub provides back-end services to LBRY clients. Services include

URL resolution
search
wallet services (getting and sending transactions, address subscription)
hub federation and discovery

This project will eventually subsume and replace the wallet server and the lighthouse search provider.

Installation

No install instructions yet. See Contributing below.

Usage

Prerequisite: run python block processor and search plugin

Follow the instructions here.

Run this hub

./hub serve

Search for stuff

./hub search text goes here

Contributing

Contributions to this project are welcome, encouraged, and compensated. Details here.

Dev Dependencies

Install Go 1.17+

Ubuntu: sudo add-apt-repository ppa:longsleep/golang-backports && sudo apt install golang-go
OSX: brew install go
Windows https://golang.org/doc/install

Download protoc from https://github.com/protocolbuffers/protobuf/releases and make sure it is executable and in your path.

Install Go plugin for protoc and python:

go get google.golang.org/protobuf/cmd/protoc-gen-go google.golang.org/grpc/cmd/protoc-gen-go-grpc
pip install grpcio grpcio-tools github3.py

Lastly the hub needs protobuf version 3.17.1, it may work with newer version but this is what it's built with, on ubuntu systems you'll have to install this from source see the GitHub actions in .github/workflows for an example of this.

Install rocksdb and setup your CGO flags, on ubuntu

sudo apt-get install libgflags-dev libsnappy-dev zlib1g-dev libbz2-dev libzstd-dev liblz4-dev
export CGO_CFLAGS="-I/path/to/rocksdb/include"
export CGO_LDFLAGS="-L/path/to/rocksdb -lrocksdb -lstdc++ -lm -lz -lsnappy -llz4 -lzstd -lbz2"

https://github.com/protocolbuffers/protobuf/releases/download/v3.17.1/protobuf-all-3.17.1.tar.gz

If you can run ./protobuf/build.sh without errors, you have go and protoc installed correctly.

Finally, run the block processor as described under Usage.

Running from Source

Run ./dev.sh to start the hub. The script will restart the hub as you make changes to *.go files.

To search, use go run . search text goes here.

Windows

reflex doesn't work on windows, so you'll need to run go run . serve and restart manually as you make changes.
