@ndn/repo-external

This package is part of NDNts, Named Data Networking libraries for the modern web.

This package allows inserting and deleting Data in ndn-python-repo. PyRepoClient type is a client for ndn-python-repo protocol. PyRepoStore type implements a subset of DataStore interfaces defined in @ndn/repo-api package.

This implementation is compatible with ndn-python-repo version 0.2a5. To install this version, run:

pip install ndn-python-repo==0.2a5 python-ndn==0.2b2.post1

import { PyRepoStore } from "@ndn/repo-external";

import { Forwarder } from "@ndn/fw";
import { L3Face } from "@ndn/l3face";
import { enableNfdPrefixReg } from "@ndn/nfdmgmt";
import { UnixTransport } from "@ndn/node-transport";
import { Data, digestSigning, Name } from "@ndn/packet";

  const repoPrefix = process.env.DEMO_PYREPO_PREFIX;

  const face = await UnixTransport.createFace({}, process.env.DEMO_NFD_UNIX ?? "/run/nfd.sock");
  enableNfdPrefixReg(face);

  const store = new PyRepoStore({
    repoPrefix: new Name(repoPrefix),
  });

  const packets: Data[] = [];
  for (let i = 0; i < 256; ++i) {
    const data = new Data(dataPrefix.append(`${i}`));
    data.freshnessPeriod = 1;
    await digestSigning.sign(data);
    packets.push(data);
  }

  console.log(`Inserting ${packets.length} packets under ${dataPrefix} to ${repoPrefix}`);

  } finally {

    face.close();
