sync yarn.lock back into package.json and lock

Question

I have package.json and yarn.lock files. yarn.lock has versions locked in, I would like to sync, and lock (without the ^) all the versions in yarn.lock, back into package.json.

Is there any easy way to do that?

In the end, I would like to not have "^" in my package.json at all as it leads to too many troubles, and I would like to upgrade packages specifically and not unknowingly when I run a fresh yarn install.

Is there any tool or way to quickly replace the versions in package.json with those exsisting inside yarn.lock?

Answer 1

I ended up making something myself:

sync-yarnlock-into-packagejson

its a tiny utility that can sync existing package.json with yarn.lock.

syncyarnlock

Syncs yarn.lock versions into an exsisting package.json file, removing dynamic numbers such as with ^, keeping static versions intact.

Install

YARN

yarn global add syncyarnlock

or

NPM

npm install -g syncyarnlock

Usage

  Usage: syncyarnlock [options]

  Sync `yarn.lock` package versions, into package.json
  Options:

    -V, --version                output the version number
    -d, --dir <path>             directory path where the yarn.lock file is located (default to current directory)
    -p, --dirPackageJson <path>  directory of project with target package.json, if not set, -d will be used
    -s, --save                   By default don't override the package.json file, make a new one instead package.json.yarn
    -k, --keepUpArrow            By default the ^ or any other dynamic numbers are removed and replaced with static ones.
    -g, --keepGit                By default direct git repositories are also replaced by the version written in yarn.
    -l, --keepLink               By default direct link: repositories are also replaced by the version written in yarn.
    -a, --keepVariable <variable>By default everything is converted to yarn version, write a part of the type you wish not to convert, seperate by comma if more than one, to not replace git and link you would use +,link:
    -h, --help                   output usage information
  Transforms yarn.lock files to JSON
