Server-side Scripting With Node.js

Flashcards covering key concepts related to server-side scripting with Node.js.

Server-side Programming

A type of programming that allows tailored content delivery to individual users and provides access to underlying OS features.

Node.js

An open-source runtime environment for executing JavaScript outside the browser, allowing writing server-side code in JavaScript.

Event loop

A single-threaded architecture in Node.js that handles incoming requests sequentially and processes them.

Asynchronous Programming

A programming paradigm that allows functions to be executed outside the main execution thread, enabling non-blocking operations.

Promise

A proxy for a value that will eventually become available, which can be resolved or rejected.

Nodemon

A module that automatically restarts a Node.js application when file changes in the directory are detected.

File I/O

Input/output operations involving reading and writing files, which can be performed asynchronously or synchronously using the fs module.

Transform Stream

A type of stream that can both read and write data, transforming the input data during the process.

EventEmitter

A Node.js class that allows for triggering and responding to events.

Microtask queue

A queue that processes asynchronous tasks such as promises after the current stack of execution is complete.

Callback hell

A situation in programming where callbacks are nested within callbacks, making the code hard to read and maintain.

Dependency

A library or module that a piece of code relies upon for functionality.

Readable Stream

A stream that allows data to be read from it.

Writable Stream

A stream that allows data to be written to it.

Duplex Stream

A stream that allows simultaneous reading and writing.

Non-blocking I/O

I/O operations that allow other tasks to proceed without waiting for the current task to complete.

Session management

The process of managing user sessions, including storing and retrieving session data.
