IDX Ceramic Todos

Submission to ETHDenver 2021 Hackathon

An application that uses a decentralized database on the Ceramic Network to securely store smart documents (todos). It’s a serverless application that ties secure smart documents to a user identity anchored on the Ethereum blockchain.

Special thanks to the IDX and Ceramic developers and to all of EthDenver for a great experience!

Technologies

Ceramic HTTP Client: Provides access to the Ceramic Network via a remote node running Ceramic.
3ID Connect: Provides authentication to a DID (used by Ceramic) from a blockchain wallet, and stores a link from this blockchain account to your DID in IDX.
IDX: Provides a way to create identity records for a DID. Records are stored on Ceramic and can represent links to blockchain accounts or other user data.
Angular: Web application framework.
NgRx: Reactive state management.

Run Dev Server with Ceramic's Clay Testnet Network

Uses Ceramic's Clay testnet network to store Todo documents. Clone project and run:

cd idx-ceramic-todos
npm i
ng serve

Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Run Dev Server on local Ceramic Network

Clone project and install packages:

cd idx-ceramic-todos
npm i

Switch to local Ceramic Network by updating path in bootstrap.js and ceramic-token.ts to:

const CERAMIC_URL = 'http://localhost:7007'

Run npm run ceramic for the local ceramic server.

Run these commands only once to place the schema on the network

node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"
SEED=<your seed generated from randomBytes above> npm run bootstrap

This creates config.json with globally unique schemas and definition DocIDs and can be shared with other apps.

Finally, run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Build

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.
