The second number, called the minor version, indicates how much new functionality has been introduced since the last significant release for instance, if this change was only small fixes or enhancements to existing features and no behavior changes were made then it would result in a higher value. Major version number indicates incompatible API changes.

PACKAGE.JSON CARET PATCH

The first number, called the major version, indicates how significant a release this is in relation to other releases with the same minor and patch levels. Semantic versioning means that developers should compose a package version of three numbers separated by periods (e.g., "0.12.31"). Most npm packages follow semantic versioning guidelines.

PACKAGE.JSON CARET HOW TO

Versioning is an important part of npm and how to use updates safely when developing web applications.

PACKAGE.JSON CARET UPDATE

Test your code after updating npm packagesĬheat Sheet: 6 must-know commands to update npm packages Step 1: Understand npm package versioning.In this blog post, I will show you how to update npm packages without breaking your project by following 4 simple steps: This is a common problem for web developers, luckily there are some easy steps to take before updating a module. The “nuclear option” is rm -rf node_modules package-lock.json & npm install, which will regenerate your package-lock.json from scratch, although this may upgrade several other libraries in the process.Have you ever tried to update a npm package and then realized that it breaks all other packages in your Javascript project?

PACKAGE.JSON CARET INSTALL

You can also npm install & npm uninstall promise-breaker, which will force it up to 5.2.0 and then remove it from package.json. You can npm uninstall amqp-connection-manager & npm install amqp-connection-manager - this will often fix the problem. doesn’t work for you (which it sometimes doesn’t - notoriously buggy, and sometimes for whatever reason you have to use an older version of npm) then there are a few other options you can try here. On small projects you might be able to get away with something like npm upgrade -depth 999 promise-breaker, but you might find this a bit slow on larger projects.

You can figure this out by running npm ls promise-breaker, which will show you how far down the dependency tree promise-breaker is.

If you depend on a library that depends on amqp-connection-manager, then promise-breaker would be at -depth 3. This will search through your package-lock.json for packages named “promise-breaker” to upgrade, but it will only do your direct dependencies (at depth 1) and their direct dependencies (at depth 2). If you peer into the package.json for amqp-connection-manager, you’ll see that it relies on: “0.x.y” versions are special here the “x” is usually treated as the major version, and the “y” as the “minor/patch” version. This means you know it should be reasonably safe to upgrade from 5.3.2 to 5.3.3 (since this only contains bug fixes) or to 5.4.0 (which has some new features, and maybe some bug fixes) but upgrading to 6.0.0 means breaking changes and you’ll probably have to do some work to do that upgrade. If not, it should upgrade the minor version if there are new features, or the patch version if there are only bug fixes. When a new version of a package comes out, it should increment the major version if there are breaking changes. Here “5” is called the major version, “3” is the minor version, and “2” is the patch version. Node.js packages have version numbers like “5.3.2”. You want to upgrade promise-breaker, but it isn’t even in your package.json! How do you go about doing this? SemVerįirst, a quick explanation of “semantic versioning”. Now let’s suppose there’s a security vulnerability in promise-breaker. This particular package has a dependency on another package called promise-breaker, so when you install ampq-connection-manager, promise-breaker gets installed automatically (although you won’t see it in your package.json). You want to install an npm package - let’s say amqp-connection-manager.
