![]() Look at our Built-in Modules Reference for a complete list of modules. Let’s say we want to read a file from the filesystem. You can add built-in core Node.js modules, community-based modules ( nodemodules ), and local modules. Yes The Node adapter for RequireJS, called r.js, will use Nodes implementation of require and Nodes search paths if the module is not found with the. It allows you to include modules in your programs. Returns that module's 'exports' property. Node.js has a set of built-in modules which you can use without any further installation. Require require are used to consume modules. Loads a module at the given file path. This validates that the path is a string, and that it exists. The main object exported by require() module is a function. It uses commonJS module system : require(), exports and module.export. When require("path") is called, NodeJS invokes the following modules, Each JavaScript file is treated as a separate module in NodeJS. when the require is invoked, a sequences of tasks are happened: call function declared in lib/module.js which assert that the path exists and was a string. After a while, the flow of the process became clearer. The require is a function that takes one argument called path, in this case the path is. I investigated by clicking between definitions, and experimenting with variables and properties inside lib/module.js. At the first step, it looks in the current folder’s node. Make sure you have install express and request module using following commands: npm install request. If I use this line of code: const test require ('tetsModule') Node.js will look at places in paths array to find this module. The project structure will look like this: 2. The module is available in the global object. Digging DeeperĪll of this happens inside the module.js file. To find out how requiring a module works, we can use or we type module in REPL mode. ![]() So I decided to dig deeper, to know what is the magic behind this. ![]() We always use the NodeJS require() function to load modules in our projects.Īccording to NodeJS documentation, require() is "to require modules." That’s all it says. ![]()
