Hook for writing to package.json file

[vjpr]

This is related to: #3027

---

I would like to use package.json5 format. Mainly for adding comments to certain dependencies and for scripts. At the moment I use an adjacent package.json.md file.

---

In a large monorepo, the same fields are often repeated in every package.json file. Ideally, package.json files would be generated.

Nx already does this. It merges package.json and project.json when running a task.

---

A lot of tools still rely on package.json such as IntelliJ. So package.json must always be kept up to date.

When running pnpm add|link|remove, I'd like it to update my package.json5 file, but also my package.json file.

1. At present pnpm prioritizes package.json over package.json5. A config option should be added for this: Prefer package.json5 over package.json #3027
2. A hook should be available to allow syncing any updates pnpm makes. Something like writePackage in pnpmfile.js.

Example

package.json
package.json5
pnpmfile.js

pnpmfile.js

export function writePackageJson() {
  fs.writeFileSync('package.json', ...)
}

pnpm add lodash

> Updates package.json5
> Runs hook to update package.json

Can’t you use meta-updater for this?

It looks like technically that could be done. Anyone brave enough to figure out how to do it?
