Getting Started with Wasm

Getting Started with Wasm

Minimum Requirements

• Node.js (>= v20)

Install the Library

If your project does not contain it already, install the peer dependency @iota/iota-sdk as well.

npm

npm install @iota/iota-sdk

Yarn

yarn add @iota/iota-sdk

pnpm

pnpm add @iota/iota-sdk

You can install the latest beta version of the library by running the following command:

npm

npm install @iota/hierarchies@alpha

Yarn

yarn add @iota/hierarchies@alpha

pnpm

pnpm add @iota/hierarchies@alpha

Build the Library

Alternatively, you can build the bindings to work with currently unreleased features. You can find instructions for this in the hierarchies repository.

Usage in Node.js and Web

The Wasm packages are bundled for both Node.js and web. To use them, you must import them from the correct entry point:

• Node.js

import { ... } from '@iota/hierarchies/node';

• Web

import { ... } from '@iota/hierarchies/web';

Usage Examples

Typescript (Node.js)

bindings/wasm/hierarchies_wasm/examples/src/01_create_federation.ts

See full example on GitHub

Typescript (Web)

import { Federation } from "@iota/hierarchies/web";
import assert from "assert";
import { getFundedClient } from "./util";

export async function createFederation(): Promise<void> {
    const hierarchies = await getFundedClient();

    const { output: federation }: { output: Federation } = await hierarchies.createNewFederation().buildAndExecute(
        hierarchies,
    );

    console.log("\n✅ Federation created successfully!");
    console.log("Federation ID: ", federation.id);

    assert(federation.id, "Federation ID should not be empty");
    assert(federation.rootAuthorities.length > 0, "Federation should have at least one root authority");
}
