Node.js Bing Image Search Stream

Query Bing Image Search API (v7) and get a readable stream of response objects.


Bing Image Search API returns up to 150 results per API call. To access more results, you need to specify the proper offset request parameter in a subsequent API call. This module automates the process of filling the offset parameter value and determines when to stop making API calls— what you get in the end is a readable stream of parsed responses.

Response objects

Please note that response objects wrap search results in the value field.

  _type: 'Images',
  totalEstimatedMatches: 834,
  nextOffset: 195,
  value: [
      name: ...,
      thumbnailUrl: ...,
      datePublished: ...,
      contentUrl: ...,

This module doesn't unwrap search results for you because response objects may contain additional metadata (e.g., queryExpansions, pivotSuggestions, similarTerms and relatedSearches).


npm install --save bing-image-search-stream

Example Usage

Here's an example the calculating the total number of search results.

const BingImageSearchStream = require('bing-image-search-stream');

let responses = [];
new BingImageSearchStream({
  query: 'kittens',
  amount: 151,
}).on('data', (data) => {
}).on('end', () => {
  const total = responses.reduce((acc, result) => acc + result.value.length, 0);
  console.log('total: ', total);

This example takes advantage of Node.js 10's experimental support for asynchronously iterating over readable streams to print out search results to the console.

const BingImageSearchStream = require('bing-image-search-stream');

(async () => {
  const resultsStream = new BingImageSearchStream({
    query: 'kittens',
    amount: 151,
  for await (const results of resultsStream) {
    for (const result of results.value) {

  • Turns a search query into a stream of search response objects
  • Ends stream when requested amount is reached or whenthere are no more results
  • Avoids results overlap by specifying the offset API parameter with previous response's nextOffset value
  • Fills in X-MSEdge-ClientID automatically based on previous API responses
