🤗 Hugging Face Hub API

Official utilities to use the Hugging Face Hub API.

Install

pnpm add @huggingface/hub

npm add @huggingface/hub

yarn add @huggingface/hub

Deno

// esm.sh
import { uploadFiles, listModels } from "https://esm.sh/@huggingface/hub"
// or npm:
import { uploadFiles, listModels } from "npm:@huggingface/hub"

Usage

For some of the calls, you need to create an account and generate an access token.

Learn how to find free models using the hub package in this interactive tutorial.

import * as hub from "@huggingface/hub";
import type { RepoDesignation } from "@huggingface/hub";

const repo: RepoDesignation = { type: "model", name: "myname/some-model" };

const {name: username} = await hub.whoAmI({accessToken: "hf_..."});

for await (const model of hub.listModels({search: {owner: username}, accessToken: "hf_..."})) {
  console.log("My model:", model);
}

const specificModel = await hub.modelInfo({name: "openai-community/gpt2"});
await hub.checkRepoAccess({repo, accessToken: "hf_..."});

await hub.createRepo({ repo, accessToken: "hf_...", license: "mit" });

await hub.uploadFiles({
  repo,
  accessToken: "hf_...",
  files: [
    // path + blob content
    {
      path: "file.txt",
      content: new Blob(["Hello World"]),
    },
    // Local file URL
    pathToFileURL("./pytorch-model.bin"),
    // Web URL
    new URL("https://huggingface.co/xlm-roberta-base/resolve/main/tokenizer.json"),
    // Path + Web URL
    {
      path: "myfile.bin",
      content: new URL("https://huggingface.co/bert-base-uncased/resolve/main/pytorch_model.bin")
    }
    // Can also work with native File in browsers
  ],
});

// or

for await (const progressEvent of await hub.uploadFilesWithProgress({
  repo,
  accessToken: "hf_...",
  files: [
    ...
  ],
})) {
  console.log(progressEvent);
}

await hub.deleteFile({repo, accessToken: "hf_...", path: "myfile.bin"});

await (await hub.downloadFile({ repo, path: "README.md" })).text();

for await (const fileInfo of hub.listFiles({repo})) {
  console.log(fileInfo);
}

await hub.deleteRepo({ repo, accessToken: "hf_..." });

OAuth Login

It’s possible to login using OAuth (“Sign in with HF”).

This will allow you get an access token to use some of the API, depending on the scopes set inside the Space or the OAuth App.

import { oauthLoginUrl, oauthHandleRedirectIfPresent } from "@huggingface/hub";

const oauthResult = await oauthHandleRedirectIfPresent();

if (!oauthResult) {
  // If the user is not logged in, redirect to the login page
  window.location.href = await oauthLoginUrl();
}

// You can use oauthResult.accessToken, oauthResult.accessTokenExpiresAt and oauthResult.userInfo
console.log(oauthResult);

Hugging face cache

The @huggingface/hub package provide basic capabilities to scan the cache directory. Learn more about Manage huggingface_hub cache-system.

scanCacheDir

You can get the list of cached repositories using the scanCacheDir function.

import { scanCacheDir } from "@huggingface/hub";

const result = await scanCacheDir();

console.log(result);

Note: this does not work in the browser

downloadFileToCacheDir

You can cache a file of a repository using the downloadFileToCacheDir function.

import { downloadFileToCacheDir } from "@huggingface/hub";

const file = await downloadFileToCacheDir({
  repo: 'foo/bar',
  path: 'README.md'
});

console.log(file);

Note: this does not work in the browser

snapshotDownload

You can download an entire repository at a given revision in the cache directory using the snapshotDownload function.

import { snapshotDownload } from "@huggingface/hub";

const directory = await snapshotDownload({
  repo: 'foo/bar',
});

console.log(directory);

The code use internally the downloadFileToCacheDir function.

Note: this does not work in the browser

Performance considerations

When uploading large files, you may want to run the commit calls inside a worker, to offload the sha256 computations.

Remote resources and local files should be passed as URL whenever it’s possible so they can be lazy loaded in chunks to reduce RAM usage. Passing a File inside the browser’s context is fine, because it natively behaves as a Blob.

Under the hood, @huggingface/hub uses a lazy blob implementation to load the file.
