NextGraph

NextGraph brings about the convergence between P2P and Semantic Web technologies, towards a decentralized, secure and privacy-preserving cloud, based on CRDTs.

This open source ecosystem provides solutions for end-users and software developers alike, wishing to use or create decentralized apps featuring: live collaboration on rich-text documents, peer to peer communication with end-to-end encryption, offline-first, local-first, portable and interoperable data, total ownership of data and software, security and privacy. Centered on repositories containing semantic data (RDF), rich text, and structured data formats like JSON, synced between peers belonging to permissioned groups of users, it offers strong eventual consistency, thanks to the use of CRDTs. Documents can be linked together, signed, shared securely, queried using the SPARQL language and organized into sites and containers.

For developers

Read our getting started guide.

For contributors

• Install Rust minimum required 1.64.0
• Install Nodejs

cargo install wasm-pack
// optionally, if you want a Rust REPL: cargo install evcxr_repl
git clone git@git.nextgraph.org:NextGraph/nextgraph-rs.git
cd nextgraph-rs
cargo build

Packages

The crates are organized as follow :

• p2p-repo : all the common types, traits and structs for the P2P repositories
• p2p-net : all the common types, traits and structs for the P2P networks
• p2p-broker : the broker code (as server and core peer)
• p2p-client-ws : the client connecting to a broker, used by the apps and verifier
• p2p-stores-lmdb : lmdb backed stores for the p2p layer
• p2p-verifier : the code of the verifier
• ngcli : CLI tool to manipulate the repos
• ngd : binary executable of the daemon (that can run a broker, verifier and/or Rust services)
• ng-app-js : contains the JS SDK, the web app, react app, and some node services

Run

Build & run executables:

// runs the daemon
cargo run --bin ngd

// runs the client
cargo run --bin ngcli

For the web apps, see the README

Test

Test all:

cargo test --all --verbose -- --nocapture

Test a single module:

cargo test --package p2p-repo --lib -- branch::test --nocapture

Test end-to-end client and server:

cargo test --package ngcli -- --nocapture

Test WASM websocket

cd ng-app-js
wasm-pack test --chrome --headless

Test Rust websocket

cargo test --package p2p-client-ws --lib --  --nocapture

Build release binaries

cargo build -r

you can then find the binaries ngcli and ngd in target/release

Generate documentation

Generate documentation for all packages without their dependencies:

cargo doc --no-deps
