const loader = new TextLoader("../../../../../../examples/src/document_loaders/example_data/example.txt")

Load

const docs = await loader.load()
docs[0]

Document {
  pageContent: 'Foo\nBar\nBaz\n\n',
  metadata: {
    source: '../../../../../../examples/src/document_loaders/example_data/example.txt'
  },
  id: undefined
}

console.log(docs[0].metadata)
