Error compiling typescript file that imports earthstar npm package

[michielbdejong]

Any pointers on how to use the earthstar npm package in a node-typescript project? This is how far I got:

mkdir test
cd test
npm install earthstar
cat << EOF > test.ts
import {
  ExtensionKnownShares,
  ExtensionSyncWeb,
  Replica,
  ReplicaDriverFs,
  Server,
} from "earthstar";
import { createServer } from "http";

const nodeServer = createServer();

const server = new Server([
  new ExtensionKnownShares({
    // known_shares.json contains a JSON array of public share addresses.
    knownSharesPath: "./known_shares.json",
    // Persist share data to disk with ReplicaDriverFs
    onCreateReplica: (shareAddress) => {
      return new Earthstar.Replica({
        driver: new ReplicaDriverFs(shareAddress, "./share_data"),
      });
    },
  }),
  new ExtensionSyncWeb({ server: nodeServer }),
], { server: nodeServer });
EOF
tsc test.ts
