async function main() {

    // This will load an existing Stronghold or create a new one automatically.
    const filepath = "./example-strong.hodl";
    const password = "my-password";
    const stronghold = await Stronghold.build(filepath, password);
    
    // This generates a new keypair stored securely in the above Stronghold, 
    // constructs a new DID Document, and publishes it to the IOTA Mainnet.
    let builder = new AccountBuilder({
        storage: stronghold,
    });
    let account = await builder.createIdentity();

    // Print the DID of the newly created identity.
    const did = account.did();
    console.log(did.toString());

    // Print the local state of the DID Document.
    const document = account.document();
    console.log(JSON.stringify(document, null, 2));

    // Print the Explorer URL for the DID.
    console.log(`Explorer URL:`, ExplorerUrl.mainnet().resolverUrl(did));
}

main()

Build

Alternatively, you can build the bindings if you have Rust installed. If not, refer to rustup.rs for the installation. Then install the necessary dependencies using:

npm install

To use the latest local changes from the Wasm bindings follow the build instructions from the IOTA Identity Wasm build section and then link the result with:

cd ../wasm
npm link
cd ../stronghold-nodejs
npm link @iota/identity-wasm

and then build the bindings

npm run build

If you linked the Wasm bindings, don't forget to unlink before packaging the module.

npm unlink --no-save @iota/identity-wasm
npm install

Minimum Requirements

The minimum supported version for node is: v16.0.0
