Is there a way i can export variables from regular javascript to be used in expressjs?
i have tried using 'exports' but it didn't work.
for example in regular js file
var search ='hello';
exports= search;
then in express file
var search= require("./file.js");
console.log(search);
all i get in the console is '{}'.
What i want is for the variable 'search' to work in my express file as well. is there a way to do this
Refer to exports shortcut in the docs:
The
exportsvariable is available within a module's file-level scope, and is assigned the value ofmodule.exportsbefore the module is evaluated.
But it also says that:
However, be aware that like any variable, if a new value is assigned to
exports, it is no longer bound tomodule.exports.
So when you do exports= search, it's not exported, only available in the module. To make it work, you just need to change it to module.exports = search.

You are doing it wrong. Here is the proper way of doing it:
Wrong way
var search ='hello';
exports= search;
Correct way
var search = 'hello';
exports.search = search;
To call it
var { search } = require('./file.js')
console.log(search)
I hope my answer was clear and good luck!
Welcome to StackOverflow! To export a variable in file1:
var search = 'hello'
export search
// OR
export var search = 'hello'
To import it in file2:
import * as someName from './file1'
someName.search
// OR
var someName = require('./file1')
someName.search
