initLearnCard

One Function to Rule Them All

While there are many init functions that are exposed and that can be used, we recommend instead sticking to the initLearnCard function.

initLearnCard is a config-driven, heavily overloaded function, that allows you to construct a wallet flexibly, without sacrificing type safety.

Under the hood, it is simply a map between the config you provide and the init function you would normally need to call, meaning calls like initLearnCard() and emptyLearnCard() are identical.

Example Usage

import { initLearnCard } from '@learncard/init';

// Constructs an empty LearnCard without key material (can not sign VCs). 
// Useful for Verifying Credentials only in a light-weight form.
const emptyLearncard = await initLearnCard();

// Constructs a LearnCard from a deterministic seed. 
const learncard = await initLearnCard({ seed: 'abc123' });

// Constructs a LearnCard default connected to LearnCard Network hosted at https://network.learncard.com
const networkLearnCard = await initLearnCard({ seed: 'abc123', network: true });

// Constructs a LearnCard default connected to VC-API at https://bridge.learncard.com for handling signing
const defaultApi = await initLearnCard({ vcApi: true });

// Constructs a LearnCard connected to a custom VC-API, with Issuer DID specified.
const customApi = await initLearnCard({ vcApi: 'vc-api.com', did: 'did:key:123' });

// Constructs a LearnCard connected to a custom VC-API that implements /did discovery endpoint.
const customApiWithDIDDiscovery = await initLearnCard({ vcApi: 'https://bridge.learncard.com' });

// Constructs a LearnCard with no plugins. Useful for building your own bespoke LearnCard
const customLearnCard = await initLearnCard({ custom: true });
