Fix npm WARN: No repository field message when running npm install

Posted on May 20, 2022

Learn how to resolve npm WARN: No repository field when running npm install

When running npm install on your JavaScript project, you may see a warning message that says “No repository field” in the console.

Here’s an example message when I installed vue on my project:

$ npm install vue
npm WARN n-app@1.0.0 No repository field.

+ vue@3.2.34
updated 21 packages and audited 21 packages in 2.092s

1 package is looking for funding
  run `npm fund` for details

found 0 vulnerabilities

The warning comes because there’s no repository property in my package.json file.

The message won’t affect the installation of modules in your project. If you want to remove it, then simply add a repository property in your package.json file.

The template is as follows:

{
  "name": "n-app",
  "version": "1.0.0",
  "repository": {
    "type": "git",
    "url": "https://github.com/nsebhastian/requirejs-starter.git"
  },
  // ... other properties
}

The above should be enough in most cases, but you can visit the repository field documentation for more details.

With the repository field added, the WARN message should disappear.

Sometimes, you may also see the warning message comes from other packages as shown below:

npm WARN package.json b-app@0.1.0 No repository field.
npm WARN package.json c-app@1.0.1 No repository field.
npm WARN package.json d-app@0.2.1 No repository field.

Only the package authors can add the repository field, so it’s okay to ignore the warning messages above. They won’t affect the packages installed in your project.

Set project as private to remove no repository warning

If you have no intention of publishing your project as a public package, you can also remove the No repository field warning by setting the project as private.

Add the private property to your package.json as follows:

{
  "name": "n-app",
  "version": "1.0.0",
  "private": true,
  // ... other properties
}

By setting the package as private, npm won’t complain about the lack of the repository field in your project.

npm will also refuse to publish your package to prevent an accidental publication of private projects.

Now you’ve learned how to remove the no repository field warnings from npm. 👌
