Project setup

npm install

Compiles and hot-reloads for development

npm run serve

Compiles and minifies for production

npm run build

Lints and fixes files

npm run lint

Clear data & restart

Clear cache for localhost, then go to http://localhost:8080/start (because it'll generate a new one automatically if you start on the /account page).

Test key contents

Register new user on test server

New users require registration. This can be done with a claim payload like this by an existing user:

  const vcClaim = {
    "@context": "https://schema.org",
    "@type": "RegisterAction",
    agent: { identifier: identity0.did },
    object: SERVICE_ID,
    participant: { identifier: newIdentity.did },
  };

On the test server, User #0 has rights to register others, so you can start playing one of two ways:

• Import the keys for the test User did:ethr:0x000Ee5654b9742f6Fe18ea970e32b97ee2247B51 by importing this seed phrase: seminar accuse mystery assist delay law thing deal image undo guard initial shallow wrestle list fragile borrow velvet tomorrow awake explain test offer control (Other test users are found here.)

• Alternatively, register someone else under User #0 automatically:

  • In the src/views/AccountViewView.vue file, uncomment the lines referring to "testServerRegisterUser".

  • Visit the /account page.

Create multiple identifiers

Go to /import-account and import a new one. Then switch identifiers on the bottom of the Your Identity page.

Create keys with alternate tools

See this page
