Question

What is the best way to incorporate an expression into a package.json file?

Query: Is there a way to automatically increase the version in a script message? I need my release message to always be one version higher than the previous.

Aim: For example, if I have version **0.1.2**, I would like to update my commit message to 0.1.3 before releasing it. While I can manually adjust it each time, I'm looking for advice on automating this process.

{
  "version": "0.1.2",
  "scripts": {
    "release": "git commit --allow-empty  -m \\\"chore: release 0.1.2\\\"",

What is the most efficient method to extract and increment the current version, then use it in the release script as desired?

"scripts": {
    "release": "git commit --allow-empty  -m {expression}",

Answer №1

To achieve your goal, consider using the semver package along with a shell script.

npm install -g semver

You can create a shell script that handles version incrementation and Git commits.

For testing purposes, you can use the example script below (release.sh):

#!/bin/bash

current_version=$(cat package.json | grep -o '"version": "[0-9.]+"' | grep -o '[0-9.]+')

new_version=$(semver bump patch $current_version)

git commit --allow-empty -m "chore: release $new_version"

Ensure the script is executable:

chmod +x release.sh

Update the "release" script in your package.json to execute this shell script:

"scripts": {
  "release": "./release.sh"
}

Feel free to customize as needed. Hopefully, this solution helps.
