const offsetSearch = await search({ terms: ['foo', 'bar'], from: 10 });

getSuggestions

Get suggestions for an array of search terms

• terms (required) - an array of strings that represent the terms to search across
• size - a number that represents the total number of results to return. Is 25 by default.

• packageName (required) - a string that represents the package name

import { getPackageInformation } from 'npms-client';
 
await getPackageInformation('npms-client');
