Mean.io and Mean.js: Amos Haviv, an Israeli software developer was the first to notice that most of the project he made for his clients involved using similar technologies and frameworks. Later, he asked other developers in the community if they felt the same about the problem and got a positive response. That was when he came up with Mean.io. Mean.js is simply a fork out from the original idea of Mean.io. It was based on the core idea of using four technologies MongoDB as the Database, Node.js & Express as the backend framework, and AngularJS as the front-end framework. With this key point in mind, he started building a boilerplate code to help jumpstart these kinds of projects. Haviv together with a company named Linnovate open-sourced the boilerplate. Because of the difference in objectives Haviv left to start a new project of his own called Mean.js.
|Structure of Module||Mean.io uses more like self-contained node packages for client and server interactions.||In Mean.js, Angular connects with Express for front-end and back-end interactions.|
|Community Support||Community support is large but stagnant.||Community support is large and is growing because of its popularity.|
|Documentation||The documentation of Mean.io is relatively less descriptive.||Because of the community support, it has a well-explained documentation|
|Community||The Community of MEAN.io is wider compare to MEAN.js.||The Community is smaller but it is gaining popularity and creating strong community.|
In recent years, Mean.js has outgrown its popularity in huge numbers. Since Mean.js and Mean.io are branches of the same tree, both these stacks can be chosen by developers for different reasons. The differences above aren’t that significant so as a developer, than that to the production team.
