Write Versions Without Running pnpm ​

Use --write-only to update package.json with maturity-aware versions and exit without delegating to pnpm.

bash
pnpm-mature update --age 7 --write-only
pnpm-mature install --age 7 --write-only

The command inspects each supported direct dependency, selects the newest semver-compatible version older than the configured age threshold, rewrites those entries in package.json, and exits. No confirmation prompt is shown and pnpm update/pnpm install is not invoked.

You can also choose write-only mode at the interactive prompt without the flag. When running pnpm-mature update interactively, pressing w at the prompt writes package.json and skips pnpm:

txt
[w] write-only  [y] write + update  [N] cancel

Why use --write-only ​

  • Review and tweak: Inspect the rewritten package.json before running pnpm yourself.
  • Staging updates: Write mature versions as part of a CI step without triggering a full install.
  • Manual control: You may prefer to run pnpm install separately with your own flags.

Preview before writing ​

Always preview selections with --dry-run first:

bash
pnpm-mature update --age 7 --dry-run
pnpm-mature update --age 7 --write-only

Combine with other flags ​

--write-only works with all other options including --relax, --age, and targeted package names:

bash
pnpm-mature update react vitest --age 30 --relax minor --write-only

After writing, run pnpm yourself to apply the changes:

bash
pnpm install
