Read DWN Records

You can get a specific record from a DWN, or an array of records.

Get Record by recordId

If you know the recordId of the record you'd like to obtain, you can use the read function:

// Reads the indicated record from the user's DWNs
  let { record } = await web5.dwn.records.read({
    message: {
      filter: {
        recordId: recordId,
      },
    },
  });

  // assuming the record has a text payload
  const text = await record.data.text();

Get Records that Match Filter

However, you may not have the recordId available, and instead need to query for records that match a specific filter. This will return an array of records:

//Query records with plain text data format
const response = await web5.dwn.records.query({
  message: {
    filter: {
      dataFormat: 'text/plain',
    },
  },
});

// Loop through returned records and print text from each
response.records.forEach(async record => {
  console.log(await record.data.text());
});
