In today’s dynamic world, churning out rapid application prototypes with super-flexible design which adapts to volatile specifications is the key business requirement. This necessitates a software stack which gives the required freedom and power to the developer to assume a flexible, locally owned schema, in-built support for end to end testability and harness the ever growing open source repository of re-usable plugins for speedy iterations.
MongoDB – Mongo DB is an open source database follow object oriented programming language because it is written on C++. It provides high availability and scalability.
Angular – Angular is a web supplication based open source framework used to create mobile and web applications. Its productivity, testability, performance and speed is much better than other web based frameworks.
Advantages of using MEAN Stack
Declarative UX and testability:
To tame the uber-flexible dynamic language and bring predictability to the output, open source BDD-style unit testing tools like Jasmine, task runners like Karma came handy.
Cloud-hosted continuous-integration services like CircleCI make life easier.
Easier debugging and code-reuse:
When you have a single language to work with across layers, it becomes easier to trace the execution thread, watch how the data gets manipulated and debug the flow with a consistent set of free open-source tools.
Libraries developed once can be seamlessly reused for front-end as well as back-end resulting in significant boost to productivity. The thriving npm.js repository for every imaginable task in hand is the proof of the pudding.
Node.js provides testable concurrency without the headaches and uncertainty of multi-threading/cron jobs. First, the I/O based event loop architecture and C++ core modules deal with thousands of requests with ultra-frugal utilization of CPU and memory unlike a JVM.
In addition to that, the dynamic load can be handled by leveraging the Cloud’s natural horizontal elastic scaling capability by launching additional instances on the fly. Finally, MongoDB’s cloud-ready replication and its features boost the performance with great availability.
