​
Setup

To access UnstructuredLoader document loader you’ll need to install the @langchain/community integration package, and create an Unstructured account and get an API key.

​
Local

You can run Unstructured locally in your computer using Docker. To do so, you need to have Docker installed. You can find the instructions to install Docker here. 
docker run -p 8000:8000 -d --rm --name unstructured-api downloads.unstructured.io/unstructured-io/unstructured-api:latest --port 8000 --host 0.0.0.0

​
Credentials

Head to unstructured.io to sign up to Unstructured and generate an API key. Once you’ve done this set the UNSTRUCTURED_API_KEY environment variable: 
export UNSTRUCTURED_API_KEY="your-api-key"

​
Installation

The LangChain UnstructuredLoader integration lives in the @langchain/community package: 
import IntegrationInstallTooltip from "@mdx_components/integration_install_tooltip.mdx";
<IntegrationInstallTooltip></IntegrationInstallTooltip>

<Npm2Yarn>
  @langchain/community @langchain/core
</Npm2Yarn>

​
Instantiation

Now we can instantiate our model object and load documents: 
import { UnstructuredLoader } from "@langchain/community/document_loaders/fs/unstructured"

const loader = new UnstructuredLoader("../../../../../../examples/src/document_loaders/example_data/notion.md")

​
Load

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

Document {
  pageContent: '# Testing the notion markdownloader',
  metadata: {
    filename: 'notion.md',
    languages: [ 'eng' ],
    filetype: 'text/plain',
    category: 'NarrativeText'
  },
  id: undefined
}

console.log(docs[0].metadata)

{
  filename: 'notion.md',
  languages: [ 'eng' ],
  filetype: 'text/plain',
  category: 'NarrativeText'
}

​
Directories

You can also load all of the files in the directory using UnstructuredDirectoryLoader, which inherits from DirectoryLoader: 
import { UnstructuredDirectoryLoader } from "@langchain/community/document_loaders/fs/unstructured";

const directoryLoader = new UnstructuredDirectoryLoader(
  "../../../../../../examples/src/document_loaders/example_data/",
  {}
);
const directoryDocs = await directoryLoader.load();
console.log("directoryDocs.length: ", directoryDocs.length);
console.log(directoryDocs[0])


Unknown file type: Star_Wars_The_Clone_Wars_S06E07_Crisis_at_the_Heart.srt
Unknown file type: test.mp3
``````output
directoryDocs.length:  247
Document {
  pageContent: 'Bitcoin: A Peer-to-Peer Electronic Cash System',
  metadata: {
    filetype: 'application/pdf',
    languages: [ 'eng' ],
    page_number: 1,
    filename: 'bitcoin.pdf',
    category: 'Title'
  },
  id: undefined
}
