Troubleshooting H10 Error (vite: not found) when Deploying NodeJS on Heroku with Vite.js

In this tutorial, we will go over how to deploy a Node.js application using Heroku with Vite.js and address the common H10 error that might occur during deployment.

1. Install Vite.js in your Node.js project:

First, you will need to have a Node.js project set up with Vite.js. If you haven’t already, you can install Vite.js in your project by running the following command:

npm install vite --save

1. Set up your Node.js project for deployment:

Once you have Vite.js installed in your project, make sure your project is set up correctly for deployment. This may include setting up a start script in your package.json file to run your Vite.js server. Here’s an example of what your package.json file might look like:

{
  "scripts": {
    "start": "vite"
  }
}

1. Deploy your Node.js application to Heroku:

To deploy your Node.js application with Vite.js to Heroku, you will need to have a Heroku account and the Heroku CLI installed on your machine. If you haven’t already done so, you can sign up for a Heroku account and install the Heroku CLI from their website.

Once you have the Heroku CLI installed, you can deploy your Node.js application to Heroku by following these steps:

• Log in to your Heroku account using the Heroku CLI:

heroku login

• Create a new Heroku app:

heroku create

• Deploy your application to Heroku using Git:

git push heroku main

• Once your application is deployed, you can open it in your browser by running:

heroku open

1. Troubleshoot the H10 error with Vite.js not found:

If you encounter the H10 error during deployment, it means that Heroku is unable to find the vite command to start your Vite.js server. This could be due to the version of Node.js or Vite.js that Heroku is using or a problem with your project setup.

To fix this error, you can try the following steps:

• Specify the Node.js version in your package.json file using the engines field:

{
  "engines": {
    "node": "x.y.z"
  }
}

Replace x.y.z with the version of Node.js that your project requires.

• Ensure that the vite command is available in your project’s node_modules directory by running npm install before deploying to Heroku.

• Make sure that Heroku is using the correct build command defined in your package.json file by setting it in the Procfile:

web: npm run start

• If the error persists, you can try updating to the latest version of Vite.js and redeploying your application.

By following these steps, you should be able to successfully deploy your Node.js application with Vite.js to Heroku and address any H10 errors that may occur during deployment.
