Usage

Web Search

Perform a web search using the webSearch method. Your IDE will provide type hints for the parameters and return types.

const webSearchResults = await braveSearch.webSearch("How many stars there are in our galaxy?", {
  count: 5,
  safesearch: "off",
  search_lang: "en",
  country: "US",
  text_decorations: false,
});
console.log(webSearchResults);

Summarized Search

Get a summarized answer for a query using the getSummarizedAnswer method. This method returns an object containing summary and webSearch promises.

const { summary, webSearch } = braveSearch.getSummarizedAnswer("How many stars there are in our galaxy?", {
  count: 5, // Number of search results to return
  safesearch: "off", // Optional: Filter for adult content (default is "moderate")
  search_lang: "en", // Optional: Language of the search results (default is "en")
  country: "US", // Optional: Country for the search results (default is "us")
  text_decorations: false, // Optional: Whether to include text decorations (default is true)
  spellcheck: false, // Optional: Whether to enable spellcheck (default is true)
  extra_snippets: true, // Optional: Whether to include extra snippets (default is false)
});

// Wait for the web search results (almost immediately)
const webSearchResponse = await webSearch;
console.log("Web Search Response:", JSON.stringify(webSearchResponse, null, 2));

// Wait for the summarized answer (can take up to couple of seconds)
const summarizedAnswer = await summary;
console.log("Summarized Answer:", JSON.stringify(summarizedAnswer, null, 2));

Local POI Search

Search for local points of interest using the localPoiSearch method.

const poiResults = await braveSearch.localPoiSearch(["poi_id1", "poi_id2"]);
console.log(poiResults);

Local Descriptions Search

Get descriptions for local points of interest using the localDescriptionsSearch method.

const descriptionResults = await braveSearch.localDescriptionsSearch(["poi_id1", "poi_id2"]);
console.log(descriptionResults);

Search Options

The library supports various search options as defined in the Brave Search API documentation. For a complete list of options and their descriptions, please refer to the Brave Search API Documentation.

Polling Options

The BraveSearch class supports configurable polling options for summarization. You can customize the polling interval and the maximum number of polling attempts by passing a PollingOptions object to the constructor.

const braveSearch = new BraveSearch(BRAVE_API_KEY, {
  pollInterval: 1000, // (default is 500ms)
  maxPollAttempts: 30, // (default is 20)
});
