<p>2016 User Survey Report April 2016 Purpose of Survey • The purpose of the 2016 Node.js User Survey was to better understand Node.js users: – what type of development work they use Node.js for – what other technologies they use with Node.js – where they are located – how many years of experience they have – how they learn new languages – how the Node.js Foundation can help them get more out of Node.js – what version of Node.js they use – more • In addition to revealing interesting insights about the current state of play and trends in web development, the survey provided important information to help The Node.js Foundation be more successful in our mission “to enable widespread adoption and help accelerate development of Node.js and other related modules…” • Survey insights are being used to inform training materials and documentation, to plan events and meet-ups and create resources to assist developers, enterprises, and tech leaders do more with Node.js Executive Summary By many measures, Node.js is the fastest growing and most significant development language right now. With 3.5 million users and an annual growth rate of 100%, Node.js is truly everywhere. This survey reveals the type of development work Node.js users do, the other technology they use with Node.js, which languages they plan to use more of, and which they plan to use less of in the coming months, and more. Key Findings Node.js: A Universal Language The full stack is no longer "front end and back end" but rather "front end, back end and connected devices," everything from the browser to your toaster all powered by JavaScript and Node.js. Node.js and Containers Take Off Both Node.js and containers are a good match for efficiently developing and deploying microservices architectures. Full “MEAN” Stack Explodes Real-time, social networking and interactive game applications use MongoDB, Express, Angular.js and Node.js to address concurrent connections and extreme scalability. Node.js Pervasive in Enterprises More than 45 percent already using the Node.js Long Term Support release (v4) geared toward medium to large enterprise users. IoT Developers Using Node.js Stand Out IoT developers using Node.js have more experience than their front end and back end counterparts and tend to use more Node.js across their stack. How Survey Was Conducted The survey was open for 15 days, from January 13 to January 28, 2016. During this time, 1,760 people from around the world completed the survey. The survey was promoted by Node.js Foundation members, through Node.js social media accounts and by email to attendees of the 2015 Node Interactive conference. Node.js User Survey Basic Stats • 1,760 respondents, of which 1,124 (64%) run Node.js in production • ~70% Developers, 22% Technical Management • 824* Node.js Developer Respondents – 62% do both Front End and Back End development – 9% do Front End, Back End and IoT development • 35% from US, 22% from Continental Europe, 6% India, 6% UK • ~15% of all respondents from large enterprises * Developer respondents that run Node.js in production Type of Development Work What areas of development are you focused on?
