Cannot find module ‘timers/promises’

When you encounter the error “Cannot find module ‘timers/promises'” in your Node.js application, it means that the required module “timers/promises” is not found or not installed in your project.

The “timers/promises” module is a built-in module in Node.js that provides timers functions such as setTimeout and setInterval with Promise-based versions. Starting from Node.js version 15.0.0, the module is experimental and is behind the “–experimental-timers” flag, so you need to explicitly enable it.

To resolve this error, you can follow these steps:

1. Make sure that you are using a Node.js version that supports the “timers/promises” module. You can check your Node.js version by running the following command in your terminal:

           node -v
         

   If your Node.js version is below 15.0.0, you need to upgrade to a newer version that supports the module. You can download the latest stable version from the official Node.js website.

2. If you are already using a compatible version of Node.js, the error might occur due to missing dependencies. In your project directory, open your terminal and run the following command to reinstall the dependencies:

           npm install
         

   This command will reinstall all the dependencies specified in your package.json file.

3. If the above steps do not resolve the issue, it could be a problem with your project’s configuration or the way you import the “timers/promises” module. You can try the following alternative syntax to import the module:

           const { setTimeout, setInterval } = require('timers/promises');
         

   This syntax directly imports the specific functions from the “timers/promises” module.

4. Additionally, if you are using ECMAScript modules (ESM) in your project, you need to use the “import” syntax instead of “require”. Here is an example of importing the “timers/promises” module using the ES modules syntax:

           import { setTimeout, setInterval } from 'timers/promises';
         

   Make sure that your project’s configuration and file extensions are set up correctly to support ECMAScript modules.

Following these steps should help you resolve the “Cannot find module ‘timers/promises'” error in your Node.js application. It’s important to ensure that your project has the required dependencies and is using a compatible version of Node.js.
