How can I specify the required Node js version in package json

0 votes
I have a Node.js project that requires Node version 12 or higher. Is there a way to specify this in the packages.json file, so that the installer will automatically check and inform the users if they need to upgrade?

Hello @kartik,

I think you can use the "engines" field:

{ "engines" : { "node" : ">=0.12" } }

As you're saying your code definitely won't work with any lower versions, you probably want the "engineStrict" flag too:

{ "engineStrict" : true }

engineStrict is now deprecated, so this will only give a warning. It's now down to the user to run npm config set engine-strict true if they want this.

Hope this is helpfull!!
ThanK you!!
