How to specify / apply a specific version of node.js for use in package.json?

Question

I am looking for a way to break an assembly if the user uses a different version of node.js as defined in the project.

Ideally, put some checks in grunt or bower or npm to stop if a specific version of npm / node is not used to start the current build.

You can use the engineStrict property in your package.json

Check the docs for more info: https://docs.npmjs.com/files/package.json

    }
}

Answer 4

"engineStrict" , "" . Node, :

You call this function in your server code. It uses a regular expression to check the version of Node using the eremzeit response. It throws an error if it does not use the corresponding version:

const checkNodeVersion = version => {
  const versionRegex = new RegExp(`^${version}\\..*`);
  const versionCorrect = process.versions.node.match(versionRegex);
  if (!versionCorrect) {
    throw Error(
      `Running on wrong Nodejs version. Please upgrade the node runtime to version ${version}`
    );
  }
};

using:

checkNodeVersion(8)
