I work in a team of about 20 other developers. All of our projects utilize npm packages and currently all of our developers are running npm to manage those packages. I'm very curious about Yarn and have it currently installed on my machine. However I'm nervous to actually use it to install packages in case it screws up a project for other developers.
My question is can one developer utilize Yarn on a project while other devs are using npm in the same repo? From what I've read, Yarn uses the same package.json file to get its dependencies. We ignore the node_modules in our repo, however we use npm shrinkwrap to lock dependencies. I know Yarn has a Yarn.lock file and that is where my concern lies. Has anyone attempted to run Yarn independently from their team and what issues have you run into?

Yarn can consume the same package. json format as npm, and can install any package from the npm registry. This will lay out your node_modules folder using Yarn's resolution algorithm that is compatible with the node. js module resolution algorithm.
Mixing npm and yarn should be avoided. Show activity on this post. Plus you get a warning from yarn as Dave Pile said because we have to push *-lock. json files changes you have to consider using npm version >= 7 to make sure whenever you install packages by npm it will update your yarn-lock.
The main difference between NPM and Yarn is the package installation process. Yarn installs packages in parallel. Yarn is optimized to fetch and install multiple packages at once. NPM will perform a serial installation process.
As a result, Yarn outperforms NPM when installing bigger files. Both tools can save dependent files to the offline cache. This allows users to install dependencies even when they are not connected to the internet. Yarn also uses the Zero install functionality starting with version 2.
Yarn doesn't read npm-shrinkwrap.json. It generates its own yarn.lock. While only you use yarn, the project in your environment might have dependencies version different then that your teammates have. However it's safe to try yarn in your own environment since it doesn't overwrite shrinkwrap file and won't impact other developers.
