ya-disk

NPM version Tests Coverage Status

This library provides methods for working with Yandex.Disk service API. Each method present with each own independent function. Example:

import info from '../lib/info';

const API_TOKEN = '1982jhk12h31iad7a(*&kjas';

(async () => {
  try {
    const { total_space, used_space } = await info(API_TOKEN);

    console.log(`
Total space: ${Math.round(total_space / 1000000000)}GB
Free space: ${Math.round((total_space - used_space) / 1000000)}MB
`);
  } catch (error) {
    console.error(error);
  }
})();

Starting from v4.x ya-disk moved from callback to Promise. If you still wish to use callbacks, pls switch to v3.x.

Installation

npm install --save ya-disk

Authorization

Each method requires an OAuth token. You can receive one manually or use one of OAuth library, i.e. passport-yandex-token.

Promises

Each returned Promise is being resolved with deserialized response body or rejected with an error. Except copy and move methods which return value extended by status code.

List of available methods

download

Downloading a file from the user drive.

link(token, path)

Getting the download link. See details. Example:

import { createWriteStream } from 'fs';
// This lib is necessary, because Yandex Disk
// returns a 302 header when you try to download file
// using provided link
import { https } from 'follow-redirects';
import { parse } from 'url';
import { download } from '../lib/download';

const API_TOKEN = '1982jhk12h31iad7a(*&kjas';
const file = 'disk:/Зима.jpg';

(async () => {
  try {
    const { href } = await download.link(API_TOKEN, file);
    const output = createWriteStream('Зима.jpg');
    const req = https.get(href, (res) => {
      res.on('end', () => output.end());
      res.pipe(output);
    });

    req.on('error', (err) => {
      throw err;
    });
    req.end();
  } catch (err) {
    console.error(err);
  }
})();

info(token)

Getting common info about user drive. See details. Example:

import { info } from 'ya-disk';

const API_TOKEN = '1982jhk12h31iad7a(*&kjas';

(async () => {
  try {
    const { total_space, used_space } = await info(API_TOKEN);

    console.log(`
Total space: ${Math.round(total_space / 1000000000)}GB
Free space: ${Math.round((total_space - used_space) / 1000000)}MB
`);
  } catch (error) {
    console.error(error);
  }
})();

list(token, [options={}])

Getting a flat list of the user files on the drive. See details.

import { list } from 'ya-disk';

const API_TOKEN = '1982jhk12h31iad7a(*&kjas';

(async () => {
  try {
    const { items } = await list(API_TOKEN);

    items.forEach((item, index) =>
      console.log(`${index + 1}. ${item.name} (${item.size}B)`)
    );
  } catch (error) {
    console.error(error);
  }
})();

meta

get(token, path, [options={}])

Getting meta-information about the resource (file or directory). See details. Example:

import { meta } from 'ya-disk';

const API_TOKEN = '1982jhk12h31iad7a(*&kjas';

(async () => {
  try {
    const metaGet = await meta.get(API_TOKEN, filePath, {
      fields: 'name,path,custom_properties'
    });
    console.log(`${metaGet.name} (${metaGet.path})`);

    Object.keys(metaGet.custom_properties).forEach((propertyName) =>
      console.log(
        `- ${propertyName}: ${metaGet.custom_properties[propertyName]}`
      )
    );
  } catch (error) {
    console.error(error);
  }
})();

With the get-method you could also get the list of files inside the folder. See Response-format. Example:

import { meta } from 'ya-disk';

const API_TOKEN = '1982jhk12h31iad7a(*&kjas';

(async () => {
  try {
    const {items} = (await meta.get(token, '/'))._embedded;
    items.forEach((item, index) => console.log(`${index + 1}: ${item.name}`));
  } catch (error) {
    console.error(error);
  }
})();

add(token, path, properties)

import { meta } from 'ya-disk';

const API_TOKEN = '1982jhk12h31iad7a(*&kjas';

(async () => {
  try {
    await meta.add(API_TOKEN, filePath, {
      my_field: 'my_value'

Examples

You may find samle of the real usage in the example folder. You should obtain the API key first. Now you can run any example with API key passed as env-variable:

API_TOKEN=[token] node examples/upload-remote-file.js

Beware that examples work in nodejs >= 14.x.
