How to call a function from another file node JS?
As the function can be called from any folder, it is better to use relative path. In your case, if you want to call log() function from within index. js file, you need to use./ or./../ path to refer the parent folder, i.e., index.js.
It can lead to confusion if you are using lots of functions from different files. To resolve this issue, you can use npm package named node-parent-path to resolve the path of parent folder. Using require you can import any function or variable. It is the most efficient way to call a function from another file.
Using require you can refactor your code and prevent naming collisions. Also, it is one of the fastest ways to load a file because it does not create a new context. A context is a set of variables that share the same view of the program at a given time. The easiest way to call a function from another file in node JS is to use require function.
It can resolve the issues of naming collisions. It also allows you to import any function or variable. The function return value can be assigned to a variable or used in an expression.
How to load a function from another file in NodeJS?
In nodejs you can call a function from another file in two ways: using the require function or using the import keyword. The require function loads a file asynchronously and returns the exported function from that file.
The import keyword just treats the exported function as an object. NodeJS has a built-in require() function that loads a JavaScript file. The code to load a function from a file is pretty straightforward. Add a comma after the filename you want to load and call the require() function.
You will need to make sure the file is in the same folder as your current file. To load a function from another file in NodeJS, add a comma after the filename you want to load and call the require() function.
The code will look something like this:
How to call a function from other file in NodeJS?
If you want to call a function from other file, you should use the require() function. The require() function is used to load a JavaScript file into the current Node file, which is usually a NodeJS module. The following code will load the file my-file.
js into the current Node file: There are basically two ways to call a function from other file in NodeJS: Use require or simply export. If you use require, in the file where you want to call the function you just need to use require function. You should first add the external file in which you have the function you want to call to the require function as an argument.
For example: To use the require function, you first need to require the file that you want to call the function from in the Node file where you want to call it. This is not the current Node file. There are two ways to require the file: As a string or as a function.
The first method is to use the require function as a string. This function takes two arguments: the file name you want to require and the name of the function you want to call.
Let’s look at
How to call a function from another module in NodeJS?
To call a function from another file in NodeJS, you need to first require the file. The file can be either a JavaScript file or a NodeJS package. You can call a function from another file in NodeJS using the require() function. The syntax for the require() function is: require(‘module1’)[‘function1’](args).
For example: You can call a function from another file in NodeJS using the require() function. The file can be either a JavaScript file or a NodeJS package. The first step you need to do is to require the file. The file can be either a JavaScript file or a NodeJS package.

How to call a function from another file in NodeJS?
In NodeJS when you create a new file, it is automatically added to the./runtimes/nodejs/node-js.js file. This file is the main file of NodeJS. We can use other files for creating function or variables. Let’s say we have two files: index.js and call.js. The file index.js will contain the main code of the NodeJS app.
The file call.js will contain the function that we want to call Use require and export to import and export functions. In NodeJS, you can require any file which exports a function or an object. The file can be a local JavaScript file or a NodeJS module.
To call a function from another file, we need to use require function. This function will load the file into memory and return the exported function.
Let’s see an example:
