@vegaprotocol/wallet-client

Wallet client for the client namespace of the Vega wallet API v0.67.3 based on its openrpc specs.

Usage

The client supports two types of connections: connecting to an external wallet app (e.g. CLI or desktop-wallet) through http, or connecting to a browser extension wallet.

External wallet

To connect to an external wallet, you can initialize the client as below:

import { WalletClient } from '@vegaprotocol/wallet-client'

const client = new WalletClient({
  type: 'http',                             // specify that you'd like to connect through HTTP
  address: 'http://localhost:1789',         // the url where the external wallet can be reached
  token: <YOUR_CONNECTION_TOKEN>,           // optional, if you have a saved connection token, pass it in here
  onTokenChange: (token: string) => {...},  // optional, if you'd like to save your connection token, upon receiving one, this callback will provide it
})

Error handling

  1. The client will check if there is an error property on the response body and will throw an WalletClientError instance wrapping the error info, and expose a code property with the jsonrpc code, and a message based on the jsonrpc message and data properties, as defined in specification.
  2. If there is a network error / any sort of http error, the client will wrap it into a WalletHttpError, which will have a code property with the relevant http error code, and the message will the the http response status text.

Browser wallet

To connect to a wallet living in a browser extension, you can initialize the client as below:

import { WalletClient } from '@vegaprotocol/wallet-client'

const client = new WalletClient({
  type: 'browser',                     // specify that you'd like to connect to a wallet living in your browser
  chromeId: <CHROME_EXTENSION_ID>      // add the id of the published extension you'd like to connect to
  firefoxId: <FIREFOX_EXTENSION_ID>    // add the id of the published extension you'd like to connect to
})

Error handling

Generating the client

Run yarn nx run wallet-client:generate to regenerate the client from the API specs. If you run this locally, the generator will need an environment variable pointing to an openrpc specs file (a remote url or a local file path) to use that as the source of for the wallet client.

WALLET_CLIENT_SPECS=https://...

NOTE: by default, the code generator should be pointed to wallet API openrpc definition

Mocks

The wallet client exposes a mock service which you can import and run anywhere:

import { MockWalletService } from '@vegaprotocol/wallet-client/mocks'

const service = new MockWalletService({ port: 1789 })

service.start()
...
service.stop()

Alternatively, you can run the yarn nx run wallet-client:start-mock from the vegawallet-ui monorepo to start a mock service.
