Using NPM packages

Apibara indexers are powered by the Deno Javascript runtime, this makes them incredibly fast and self-contained.

Indexers dependencies are loaded from external CDNs like:

• ESM.sh. This is the recommended choice.
• JsDelivr.

You can read more about managing dependencies on the official Deno documentation.

The following script loads common utilities from Starknet.js and Viem.

import { hash, uint256 } from "https://esm.run/starknet@5.14";
import { formatUnits } from "https://esm.run/viem@1.4";
