This means that we can just keep the conflicts in the lock file.Īll we have to do is get package.json right, and npm will do the rest for us. If -package-lock-only is provided, it will do this without also modifying your local node_modules/. npm will automatically resolve any conflicts for you and write a merged package lock that includes all the dependencies from both branches in a reasonable tree.

As of these conflicts can be resolved by manually fixing any package.json conflicts, and then running npm install again.
Occasionally, two separate npm install will create package locks that cause merge conflicts in source control systems. Npm can automatically detect conflicts in package-lock.json and resolve them for us.
However, I recently learned about and even easier way: This will then just re-install whatever changes we made in our branch. Take package-lock.json from the base branch.No one can tell.įor me, this would usually mean: "regression test everything", which is certainly not what I have in mind when I am just solving a conflict. If you delete package-lock.json now from any one of your projects and run npm install again, it will most certainly look completely different. So even if you are using strict versions (without the ^), the libraries you are using do not. This also applies to transitive dependencies.Have a look at your package-lock.json and count how many dependencies with major version 0 you have.įor this blog (made with gatsby) I have 362! The public API SHOULD NOT be considered stable. Major version zero (0.y.z) is for initial development. Major version zero is exempt from the rules of semantic versioning.It trusts that everyone strictly adheres to semantic versioning, and I sincerely doubt that this is the case.This means no major changes, but minors and patches. So when you delete package-lock.json, all those consistency goes out the window.Įvery node_module you depend on will be updated to the latest version it is theoretically compatible with.
Lock me now 2 github Patch#
I would not want to ship a newer version to production than we tested with, even if it's just a patch version. This is important because it guarantees that every developer in the team will have the same version on their machine, and it is equally important for CI/CD. So if 4.2.1 is the latest version at the moment of your install, this version will be written to package-lock and will, from there on, always be installed.Įven if newer versions come out that are theoretically compatible with it. Upon installing, it will "lock" you in on the version that you just installed. This is where package-lock.json comes into play. Which means "compatible with version, according to semver".Įnter, for example, lodash as the package and ^4.2.1 as version,Īnd you will see that you can get anything from 4.2.1 to 4.17.20 (the latest version) When you install a dependency for the first time, it is usually automatically added to your dependencies or devDependencies with ^version, Why you should never delete package-lock.json The conflicts in package.json are usually easily solved (if there even are any), so I think it is tempting to just delete package-lock.json and run npm install.Īfter all, this will give you a brand new package-lock.json, which you can happily commit. So here you are, updating your PR with the base branch, and git shows you this huge amount of conflicts in package-lock.json.
The result of package-lock then changes, and whoever gets their PR merged to main first is the lucky one who avoided those conflicts.
Lock me now 2 github update#
It usually happens when two branches add or update a dependency. One thing that can be costly when done wrong is solving conflicts in generated files, like package-lock.json. I wish I wouldn't spend as much time solving git conflicts as I currently am.
