@slide-computer/signer v3.16.0

@slide-computer/signer

JavaScript and TypeScript library to interact with signers on the Internet Computer.

Installation

Using Signer:

npm i --save @slide-computer/signer

In the browser:

import { Signer } from "@slide-computer/signer";

To get started with the signer, run

// Create transport with e.g. "@slide-computer/signer-web"
const signer = new Signer({transport});

Make sure to connect before using signer if the transport requires a connection

if (transport.connection && !transport.connection.connected) {
    await transport.connection.connect();
}

The signer can for example get accounts with

const accounts = await signer.accounts();

Optionally, the permission can be requested beforehand to get accounts

const permissions = await signer.requestPermissions([createAccountsPermissionScope()]);

Making canister calls

The @slide-computer/signer-agent package offers SignerAgent as drop in replacement of HttpAgent.

Besides making canister calls through signers that need to be approved by users, calls can also be made after requesting a delegation from the signer with the delegation() method. This delegation can then be used to create a DelegationIdentity which in turn can be used with the HttpAgent.

List of available transports

Efforts are made to standardize the transports, for example ICRC-29 and ICRC-94. For wallets that do not implement a standardized transport method, additional polyfill packages are available.
