is it good practice to add nodes and client folder to chef server template

I am still learning about chef. I have bootstrapped and uploaded my server-template to remote repository. But am wondering if its safe to add nodes directory to remote repository as it contains exact server passwords

Here is an example node

{
  "environment":"production",
  "authorization": {
    "sudo": {
      // The password for the depliy user is set in data_bags/users/deploy.json
      // and should be generated using:
      // openssl passwd -1 "plaintextpassword"
      "users": ["deploy", "vagrant"]
    }
  },

  "vagrant" : {
    "exclusions" : [],
    "name" : "rails-postgres-redis1",
    "ip" : "192.168.50.4"
  },
  "rbenv":{
    "rubies": [
      "2.1.2"
    ],
    "global" : "2.1.2",
    "gems": {
      "2.1.2" : [
        {"name":"bundler"}
      ]
    }
  },
  "monit": {
    "notify_emails" : ["email@example.com"],
    "enable_emails" : false,
    "web_interface" : {
      // the plaintext monit username and password
      "allow" : ["your_username","your_password"]
    },
    "mailserver" : {
      "host" : "mailserver.example.com",
      "port" : "999",
      "username" : "your_username",
      "password" : "your_password",
      "hostname" : "the_hostname"
    }
  },
  "postgresql" : {
    "password" : {
      // this should be generated with:
      // openssl passwd -1 "plaintextpassword"
      // currently test
      "postgres" : "$1$mMK9HNoN$r42n7Q8fKsZabbknlT1Zt1"
    }
  },
  "run_list":
  [
    "role[server]",
    "role[nginx-server]",
    "role[postgres-server]",
    "role[rails-app]",
    "role[redis-server]",
  ]
}

As the passwords are visible is it safe to add like this?

If it should be in gitignore then at a later stage if we clone from the remote repo then we need to bootstrap the server from scratch as there is no node directory exists right?

Is there a better way or am I missing something here?

You do not need copy of node json files to bootstrap the node. Secure data should come from Chef Vault/Hashicorp Vault/any other secure storage. Non-confidential data can be part of recipe/wrapper recipe/role/environment/etc, which can be stored in the repository. If you really have data which are single node specific you can pass them using -j during the bootstrap process.
