Make `npm install --save` add a strict version to package.json

Question

When you run npm install --save somepackage, it usually adds something like this into package.json:

\"dependencies\": {
    \"somepackage\": \"^2.1.         


        

Answer 1

To specify by default a exact version, you can change your npm config with save-exact:

npm config set save-exact true

You can also specify the prepend version with a tilde with save-prefix.

And, no you can't force user to update to a minor or a patch version, NPM uses semver and it's the recommend way of publishing packages.

Answer 2

Run:

npm install --save --save-exact my-module@my-specific-version

_{Adding an answer to make this advice easier to see.}

Answer 3

You can change the default behaviour by using the --save-exact option.

// npm
npm install --save --save-exact react

// yarn
yarn add --exact react
