ng-sdk-js

JS/WASM crate containing the SDK of NextGraph

NextGraph

NextGraph brings about the convergence of 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 (a platform) and software developers (a framework), 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.

an example of web app using the ESmodule and webpack as bundler app-web
an example of React web app app-react
an example of node-js app app-node
index.html an example of vanilla JS usage of the SDK

npm i ng-sdk-js

For contributors

We recommend contributors to use the production build, as the creation and opening of wallets is very slow in the dev build. Only use the dev build when debugging the sdk. see the next chapter for the production build. Please note that the dev and prod builds share the same output folder, they thus override each other. When building the app, be sure to have the production build of the SDK in the output folder.

wasm-pack build --dev --target bundler

wasm-pack build --dev -t nodejs -d pkg-node
node prepare-node.js

For testing in vanilla JS

wasm-pack build --dev --target web -d web
python3 -m http.server
// open http://localhost:8000

Or automated testing with headless chrome:

wasm-pack test --chrome --headless

Production build

wasm-pack build --target bundler
tar --exclude .DS_Store -zcvf pkg.tar.gz pkg
wasm-pack build -t nodejs -d pkg-node
wasm-pack build --target web -d web
node prepare-node.js
cd pkg
npm publish --access=public
cd ../pkg-node
npm publish --access=public

Example Plain JS web app

cd ../app-web
// for local development
npm install --no-save ../pkg
// or, for install from npm registry: npm install
npm start

Open this URL in browser : http://localhost:8080

Example React web app

cd ../app-react
// for local development
npm install --no-save ../pkg
// or, for install from npm registry: npm install
npm run dev

This URL will open automatically in browser : http://localhost:8080

Example NodeJS app

cd ../app-node
// for local development
npm install --no-save ../pkg-node
// or, for install from npm registry: npm install
npm run start
