[FIXED] how to pass correctly a module in node

Issue

app.js --------------

const mongoose = require("mongoose");
const utils = require("./config/utils");
const app = express();

utils.initializeDb(mongoose);
app.listen(3000);

config/utils.js

module.exports = (mongoose) => {
  initializeDb: async () => {
    await mongoose.connect(
      process.env.MONGO_URI,
      {
        useNewUrlParser: true,
      },
      () => {
        console.log("Mongoose connection successfuly started");
      }
    );
  };
};

The error in the terminal/console is: TypeError: utils.initializeDb is not a function.

I'm digging into optimization, encapsulation, to clean more my code passing modules through functions and etc. and I tried this thing but it give me this error... I would like to know the error that is happening in the code and also some tips on how to optimize this code. Thank you :)

Solution

try the below method :

app.js

    const mongoose = require("mongoose");
    const initializeDb = require("./config/utils");
    const app = express();

    initializeDb(mongoose);
    app.listen(3000);

config/utils.js

module.exports = {
  initializeDb: async (mongoose) => {
    await mongoose.connect(
      process.env.MONGO_URI,
      {
        useNewUrlParser: true,
      },
      () => {
        console.log("Mongoose connection successfuly started");
      }
    );
  };
};
