Unable to git push my node.js server to Heroku, says no bower.json present

Question

I am developing a Node.js server for my MERN application and trying to deploy the server on Heroku. However, after I followed the usual commands on Heroku's page for my app, and run git add ., git commit -am "Deploy commit", and git push heroku master, it wasn't able to successfully push the commit.

I have attached my package.json and log file below.

My package.json file:

{
  "name": "server",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "bower install && grunt build",
    "start": "nodemon index.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "bcryptjs": "^2.4.3",
    "bower": "^1.8.13",

    "path": "^0.12.7"
  },
  "engines": {
    "node": "16.x",
    "npm": "8.x"
  }
}

After encountering the above error, I added a registry for my .bowerrc file like so:

{
  "registry": "https://registry.bower.io"
}

Even this hasn't been really helpful. How can I fix this?

Answer 1

After a bit of research, I got the build success message. Here's what I did to get it working:

1. So the first thing I did was npm install bower-json.
2. After that, I used bower init and initialized the app.
3. Then I removed the build under scripts in package.json.
4. Following this, I went for another git add, git commit, and git push heroku master.

This process got my build successful!
