Walmart needed to improve its business. That’s not normally said about an international mega-corporation that made $482 billion in revenue last fiscal year, but Walmart has set its sights on becoming the world’s largest online retailer. currently offers more than 23 million items for sale, and is rapidly expanding; earlier this year the company announced it’s inviting retail partners and smaller vendors to sell on the site.

The company already sees close to 20,000 hits per second on its website and mobile app during the holiday season, so it needs to build a fast, reliable, usable and bulletproof ecommerce system to reach its goals of becoming a leader in the online retail space.

That’s why it’s rebuilding with Node.js.

  • Node.js Keeps Walmart Top of Mind: Node.js helps keep its content in front of Google and other search indexing robots with the help or React.js
