Clinic.js can pinpoint performance bottlenecks
We’ve been solving major performance problems for large enterprises for years, from Conde Nast and News UK to Protocol Labs and Moody’s using Node.js as a key implementation technology. We work with developers, architects and organisations like yours to uncover your bottlenecks and provide recommendations on how to solve them with the right tech stack to power your needs.
From the early days of Node.js contributions through to our leadership in Fastify, HTTP2, Pino, Clinic.js and React ESX, we have built upon our expertise and our sheer focus to radically improve performance across the entire enterprise system architecture from top to bottom. We help organisations achieve superior performance in not just applications and servers but in their processes, people and workflows too.
If you have an immediate need to address performance issues in your Node.js applications, take a look at Clinic.js and what it can do to help.
Maintaining high security without sacrificing performance in deployments of up to 40,000 users was the key requirement for the new system. Together with NearForm, we came through with a powerful system, we met our deadlines and delivered a superior end product.
NearForm has an extremely strong competency in Node.js , and that was a big selling point for Condé Nast International. Node.js was ideal for this engagement: whether you’re looking at the front-end or the back-end engineering, it gives you increased flexibility.
