Steer clear of unreliable versions of mongoose in npm or package.json files

Is there a way to prevent the installation of unstable versions of mongoose with npm?

Upon executing npm update, I receive this warning in my node application:

#   !!! MONGOOSE WARNING !!!
#
#   This is an UNSTABLE release of Mongoose.
#   Unstable releases are available for preview/testing only.
#   DO NOT run this in production.

Within my package.json file, I have the following line:

"mongoose": "^3.8.8"

Answer №1

Due to Mongoose deviating from standard npm practices, their unstable releases are mistakenly identified as stable by npm. This issue stems from the release of version 3.9 as an unstable build.

I recommend no longer relying on Mongoose to adhere to these conventions and instead specify a fixed version in your package.json:

 "mongoose": "3.8"

Answer №2

Here is a helpful solution for updating dependencies in your package.json file: How to update each dependency in package.json to the latest version?

One common advice is to use "*" as the version so that you always get the latest stable version.

In your specific case, it might be beneficial to first uninstall the mongoose package and then reinstall it.

The recommended steps are:

npm uninstall mongoose
(update "mongoose":"^3.8.8" to "mongoose":"3.8")
npm install

Answer №3

It is possible that you never actually installed version 3.8.8 initially (which is considered stable), but rather a version in the 3.9.x range.

By using the ^ symbol, you are indicating that you want to install any version within the 3.9.x range even if you specified ^3.8.8 in your package.json file.

In this scenario, you have two options: either correct the version to be 3.8.8 (or 3.8.18 which is stable at present by removing the ^) or utilize the ~ character, which will only match versions with the same lowermost version part.

For example:

*      => x.x
^3.8.8 => 3.x
~3.8.8 => 3.8.x
3.8.8  => 3.8.8

The issue arises because although 3.9 is unstable, using ^ will lead to 3.9 being picked.

A detailed explanation on versioning can also be found here: https://example.com

You can also check available versions by running:

npm view mongoose versions

This will show what versions are accessible, such as the latest in 3.8 when version 4 is released.

Using ~3.8 will always keep it up to date within the 3.8 range, but manual intervention will be required once 4.0 becomes available.

Additionally, you have the option to directly edit the package.json file and then run:

npm update

This way, you can update without the need for uninstalling and reinstalling.
