AWS launches Lambda Web Functions for Node.js apps

AWS introduced Lambda Web Functions, letting developers run Node.js apps built with Express, Hono, Fastify or Next.js directly on Lambda without adapters, with concurrent requests and response streaming. Billing is based on active CPU time and memory rather than time spent waiting on downstream services. The service is available in five regions and currently supports only Node.js.

• Supports Express, Hono, Fastify and Next.js without adapters or code changes
• A single warm environment handles multiple concurrent requests, cutting cold starts
• Billing covers active CPU time and memory, not time waiting on downstream services
• Available in five regions: N. Virginia, Ohio, Oregon, Tokyo and Ireland
