- nodejs package loading process
- Node.js is a Javascript running environment based on event-driven, non-blocking I/O. It allows us to organize and manage code more conveniently through an integrated modular system. In Node.js, modularization is an important concept. Each file is treated as an independent module, and these modules can be loaded through the require function. In Node.js, the module loading process is mainly divided into three steps: path analysis, file location and compilation execution. Below we will introduce the process and working principle of these three steps in detail. path
