  • Accumulators
  • Anchors
  • Blobs
  • Support for public keys including BBS, BBS+, PS, Ed25519, Sr25519, and Secp256k1
  • BBS/BBS+/PS parameters
  • Status List credentials
  • Trust Registries

Install or build

  • Run yarn add @docknetwork/dock-blockchain-modules or npm install @docknetwork/dock-blockchain-modules to install the package from npm
  • When building from source:
    • Run yarn to install the dependencies
    • Run yarn build to create a distribution version.

Documentation

Have a look at the concepts and tutorials. These are generated from markdown present over here. Files prefixed with concepts describe the concepts and files prefixed with tutorials have a tutorial on using the API. Checkout the API reference

Examples

The example scripts present in example directory are meant to demonstrate a complete feature. The following commands demonstrate different features.

Connecting

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

Running dev node:

yarn dev-node

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 tests with yarn test (required node to be running).

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

yarn test-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
