What is a module? A module is a block of code in a file. Modules are the bricks for structuring applications that are too big to efficiently maintain in a single file. They are the main mechanism to enforce information hiding by keeping private all the functions and variables that are not explicitly exported. The […]
TL;DR:
1. Use setImmediate
2. Delegate to a child process
3. Delegate to a worker thread

The reactor pattern is the heart of Node.js. It is a specialisation of the previously discussed event demultiplexer algorithm. libuv, the non-blocking I/O engine of Node.js, implements the reactor pattern. So, how does it work? Let’s say there’s a single threaded application interested in reading data from a file (an I/O operation). The application kicks

Operating systems provide another native mechanism to handle concurrent, non-blocking resources efficiently. This mechanism is called synchronous event demultiplexer or event notification interface.
This component collects and queues I/O events that come from a set of watched resources, and block until new events are available to process.
Why do we need an event loop? Read More »
