How do you share constants in NodeJS modules?

Question

Currently I\'m doing this:

foo.js

const FOO = 5;

module.exports = {
    FOO: FOO
};

And using it in bar.js:<

Answer 1

I think that const solves the problem for most people looking for this anwwer. If you really need an immutable constant, look into the other answers. To keep everything organized I save all constants on a folder and then require the whole folder.

src/main.js file

const constants = require("./consts_folder");

src/consts_folder/index.js

const deal = require("./deal.js")
const note = require("./note.js")


module.exports = {
  deal,
  note
}

Ps. here the deal and note will be first level on the main.js

src/consts_folder/note.js

exports.obj = {
  type: "object",
  description: "I'm a note object"
}

Ps. obj will be second level on the main.js

src/consts_folder/deal.js

exports.str = "I'm a deal string"

Ps. str will be second level on the main.js

Final result on main.js file:

console.log(constants.deal); Ouput:

{ deal: { str: 'I\'m a deal string' },

console.log(constants.note); Ouput:

note: { obj: { type: 'object', description: 'I\'m a note object' } }
