# nextgraph-rs

Rust implementation of NextGraph

This repository is in active development at [https://git.nextgraph.org/NextGraph/nextgraph-rs](https://git.nextgraph.org/NextGraph/nextgraph-rs), a Gitea instance. For bug reports, issues, merge requests, and in order to join the dev team, please visit the link above and create an account (you can do so with a github account). The [github repo](https://github.com/nextgraph-org/nextgraph-rs) is just a read-only mirror that does not accept issues.

## 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.

## How to use NextGraph

NextGraph is not ready yet. You can subscribe to [our newsletter](https://list.nextgraph.org/subscription/form) to get updates, and support us with a [donation](https://nextgraph.org/donate/).

## For developers

Read our [getting started guide](https://docs.nextgraph.org/en/getting-started/).

## For contributors

- [Install Rust](https://www.rust-lang.org/tools/install) minimum required MSRV 1.64.0
- [Install Nodejs](https://nodejs.org/en/download/)
- [Install LLVM](https://rust-lang.github.io/rust-bindgen/requirements.html)

until this [PR](https://github.com/rustwasm/wasm-pack/pull/1271) is accepted, will have to install wasm-pack this way:

```
cargo install wasm-pack --git https://github.com/rustwasm/wasm-pack.git --rev c2b663f25abe50631a236d57a8c6d7fd806413b2
cargo install cargo-watch
// optionally, if you want a Rust REPL: cargo install evcxr_repl
git clone git@git.nextgraph.org:NextGraph/nextgraph-rs.git
// or if you don't have a git account: git clone https://git.nextgraph.org/NextGraph/nextgraph-rs.git
cd nextgraph-rs
cargo build
```

### Packages

The crates are organized as follow :

- p2p-repo : NextGraph repositories common library
- p2p-net : P2P network common library
- p2p-broker : the broker code (as server and core node)
- p2p-client-ws : the client connecting to a broker with WebSocket, used by the apps and verifier
- p2p-verifier : the code of the verifier
- stores-lmdb : lmdb backed stores
- ngcli : CLI tool to manipulate the repos and administrate the server
- ngd : binary executable of the daemon (that can run a broker, verifier and/or Rust services)
- ng-wallet : keeps the secret keys of all identities of the user in a safe wallet
- [ng-sdk-js](ng-sdk-js/README.md) : contains the JS SDK, with example apps: web app, react app, or node service.
- [ng-app](ng-app/README.md) : all the native apps, based on Tauri, and the web app.
- [ngone](ngone/README.md) : server for nextgraph.one (helps user bootstrap into the right app)
- [ngaccount](ngaccount/README.md) : server for nextgraph's Broker Service Provider account manager.

### Run

Build & run debug executables:

```
// runs the daemon
cargo run --bin ngd

// runs the client
cargo run --bin ngcli
```

For the web apps, see the [README](ng-app/README.md)

### 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-sdk-js
wasm-pack test --chrome --headless
```

Test Rust websocket

```
cargo test --package p2p-client-ws --lib -- remote_ws::test::test_ws --nocapture
```

### Build release binaries

First you will need to have the production build of the frontend.
If you do not want to setup a whole development environment for the frontend, you can use the precompiled release of the frontend available in `dist-file.tar.gz`

```
cd ng-app
tar -xzf dist-file.tar.gz
cd ..
```

Otherwise, build from source the single-file release of ng-app

```
npm install -g pnpm
cd ng-sdk-js
wasm-pack build --target bundler
cd ../ng-app
pnpm install
pnpm webfilebuild
cd ..
```

then build the ngd daemon

```
cargo build -r -p ngd
```

you can then find the binary `ngd` in `target/release`

The CLI tool can be obtained with :

```
cargo build -r -p ngcli
```

you can then use the binary `target/release/ngcli`

For usage, see the documentation [here](ngd/README.md).

For building the apps, see this [documentation](ng-app/README.md).

#### OpenBSD

On OpenBSD, a conflict between the installed LibreSSL library and the reqwest crate, need a bit of attention.
Before compiling the daemon for OpenBSD, please comment out lines 32-33 of `p2p-repo/Cargo.toml`. This will be solved soon in a more appropriate way.

```
#[target.'cfg(target_arch = "wasm32")'.dependencies]
#reqwest = { version = "0.11.18", features = ["json","native-tls-vendored"] }
```

to use the app on OpenBSD, you need to run the daemon locally.

```
ngd -l 14400 --save-key
```

then open chrome (previously installed with `doas pkg_add chrome`)

```
env ENABLE_WASM=1 chrome --enable-wasm --process-per-site --new-window --app=http://localhost:14400
```

### Generate documentation

Generate documentation for all packages without their dependencies:

```
cargo doc --no-deps
```

The generated documentation can be found in `target/doc/<crate-name>`.
