    id: "https://example.com/id/1234324",
    type: ['VerifiableCredential'],

const vcJwt = await issue(vc, {
    issuer
});

const isVerified = await verify(vcJwt);

Development

TSDX scaffolds your new library inside /src.

To run TSDX, use:

npm start # or yarn start

This builds to /dist and runs the project in watch mode so any edits you save inside src causes a rebuild to /dist.

To do a one-off build, use npm run build or yarn build.

To run tests, use npm test or yarn test.

Publish

npm run build
npm publish
