# How to solve "Error [ERR_MODULE_NOT_FOUND] "

Hello and welcome!

Are you facing the "Error \[ERR\_MODULE\_NOT\_FOUND\]" error while trying to import a module in your Node.js application? Don't worry, in this article, we'll guide you through the steps to solve this error and get your application up and running again.

### Check The Syntax Of import Or export :

This is the correct format of code:

```javascript
// import syntax
import  dataString from "./model/user.js";
import { userRouter } from "./router/users.js";

// export syntax
export { router as userRouter } 
export default dataString
```

### Check Package.json file for type:"module":

Make sure you have specify "type" : "module"

```javascript
{
//check this 👇
  "type": "module",
  "dependencies": {
    "bcrypt": "^5.1.0",
    "cors": "^2.8.5",
    "express": "^4.18.2",
    "jsonwebtoken": "^9.0.0",
    "mongoose": "^7.0.5"
  }
}
```

By default it is "type" : " commonjs" you have to add "type" : "module" in package.json file.

### Make sure your Path you have pass is correct:

```javascript
~ crud_app
    ~ src
        ~ models
            ~ dataString

import dataString from "./src/models/dataString
```

### If it is still not solved?

make sure that you are not mixing the use of `require()` and `import` statements in your application. Stick to one syntax throughout your application.

By following these steps, you should be able to resolve the "Error \[ERR\_MODULE\_NOT\_FOUND\]" error and get back to coding in no time. Happy coding!
