changeset version reformats package.json files #1434
Description
Problem
when running npm changeset version, the package.json file is being formatted.
The formatting turns this:
"files": ["dist"],to this:
"files": [
"dist"
],This formatting is WRONG.
A. Why does it need to happen?
B. What is causing the formatting?
I have no husky, I have no prettier. I am using VSCode, and the formatOnSave is disabled.
This is a very small project created today.
This is a HUGE ISSUE for me

B. That's how
JSON.stringifystringifies JSON when using thespaceparameter.A. If the
spaceparameter isn't used,JSON.stringifystringifies JSON as a single line.You can see the difference here: https://stackblitz.com/edit/vitejs-vite-f9dpnq?file=src%2Fmain.ts

Is there a way to tell changesets to run a custom npm script that formats the file?
For example:
It would need to run after changesets updates
package.jsonand before it creates a Pull Request.talkohavy commentedon Nov 20, 2024
sadly, to this day of writing the comment, there isn't...
I hate to be doing this in a another package's thread..., but I ended up switching to another tool on npm, called
lvlup, which doesn't format yourpackage.jsonat all, and only works for a single repo (not a monorepo with many packages) and just performs a simple find & replace.Full Disclosure⚠️
The tool barely has weekly downloads,
as I am the developer/maintainer of it. I find myself often creating new packages and needed an appropriate tool.

I have this problem too and it is frustrating, I hope some sort of post publish step in CI becomes available so I can run the formatter, it's annoying getting formatting issues in the
mainbranch every time after publishing.tk-o commentedon Feb 20, 2025
You can turn prettier auto-formatting off now with this release:

prettier: falsein my changeset configHugos68 commentedon Apr 9, 2025
@shrugs did you update your changeset package?

@shrugs if you still have this issue let me know and i'll re-open the issue!
beeequeue commentedon Apr 30, 2026
actually sorry, this is related to the package.json writing which is unaffected by Prettier. i will create an umbrella issue for this later
