• Run example to create a new DID, register it, update its key and remove the DID.

  yarn dock-did-example

• Run example to resolve DID

  yarn did-resolver-example

• Run example to see revocation

  yarn revocation-example

• Run example to see verifiable credentials

  yarn vcdm-example

Connecting

Use Dock's substrate node: https://github.com/docknetwork/dock-substrate

Running dev node:

./target/release/dock-node --base-path /tmp/alice --chain local_poa_testnet --alice --port 30333 --ws-port 9944 --rpc-port 9933 --telemetry-url 'wss://telemetry.polkadot.io/submit/ 0'

Use the mainnet tag of this repo when interacting with mainnet as the master branch isn't guaranteed to be mainnet compatible.

Test and example Configuration

Configuration variables like websocket endpoint for node FullNodeEndpoint, URI for account to pay for extrinsics TestAccountURI and keyring type TestKeyringType can be set as environment variables (or in an .env file). If they are not set, default values as specified in file test-constants.js are used. The scripts read parameters from .env file. The available parameters are shown in an example env file env_example

Test

Run unit tests with yarn test.

Run a single unit test module with yarn test <module name or prefix>.

Run e2e integrations tests with yarn test-integration (required node to be running)

You can run tests against a temporary node in docker like so:

./scripts/with_docker_test_node
yarn test-integration

or with the alias:

yarn test-with-node

and examples can be similarly run with:

yarn examples-with-node

Linting and type checking

We use JSDoc and TypeScript for static type checking during the CI process. PRs must pass linting and type checking to be accepted. You can run via: yarn lint --fix and yarn type-check
