import createClient from '@natlibfi/oai-pmh-client';
const client = createClient({url: 'https://foo.bar', metadataPrefix: 'marc'});

client.listRecords()
  .on('record', record => processRecord(string))
  .on('end', () => endProcessing())
  .on('error', err => handleError(err));

import createClient from '@natlibfi/oai-pmh-client';
const client = createClient({url: 'https://foo.bar', metadataPrefix: 'marc', retrieveAll: false});

client.listRecords()
  .on('record', record => processRecord(string))
  .on('end', resumptionToken => endProcessing(resumptionToken))
  .on('error', err => handleError(err));

And then use the returned resumption token:

client.listRecords({resumptionToken})
  .on('record', record => processRecord(string))
  .on('end', resumptionToken => endProcessing(resumptionToken))
  .on('error', err => handleError(err));
