Using NPM install highest semver major version X

Using package.json and NPM how can I install, using the command line, the highest number of major version 1 or major version 2?

In this case, I want to downgrade a package from version 2.x.x to 1.x.x. And this case, I want x to be the biggest number possible.

Something like:

npm install foo@latest:1

I am not sure. My end goal is to get the right data into package.json, such that I never jump to version 2.0.0, and always remain at the highest 1.x.x version.

Is there something I can manually insert into package.json? then run npm install foo?

Unfortunately the NPM article on semver is not helping much.

If you want to do that manually:

npm install <package-name>@^xx

e.g. npm install react@^18 will install the latest minor version of major version 18.

If you're wanting to always pick the latest and greatest for a particular version but not wanting to jump major version then you can use the ^ prefix in the package.json.

Example:

"dependencies": {
    "nodemailer": "^2.3.2"
  },

Note: The latest major release for nodemailer is version 4.

This will resolves to [email protected], which is the last release for version 2.

Doing npm install produces the following

Output:

npm WARN deprecated [email protected]: All versions below 4.0.1 of Nodemailer are deprecated. See https://nodemailer.com/status/
npm WARN deprecated [email protected]: the module is now available as 'css-select'
npm WARN deprecated [email protected]: the module is now available as 'css-what'
[email protected] node_modules/nodemailer
