update package.json version automatically

Question

Before I do a small release and tag it, I\'d like to update the package.json to reflect the new version of the program.

Is there a way to edit the file package

First, you need to understand the rules for upgrading the versioning number. You can read more about the semantic version here.

Each version will have x.y.z version where it defines for different purpose as shown below.

1. x - major, up this when you have major changes and it is huge discrepancy of changes occurred.
2. y - minor, up this when you have new functionality or enhancement occurred.
3. z - patch, up this when you have bugs fixed or revert changes on earlier version.

To run the scripts, you can define it in your package.json.

"script": {
    "buildmajor": "npm version major && ng build --prod",
    "buildminor": "npm version minor && ng build --prod",
    "buildpatch": "npm version patch && ng build --prod"
}

In your terminal, you just need to npm run accordingly to your needs like

npm run buildpatch

If run it in git repo, the default git-tag-version is true and if you do not wish to do so, you can add below command into your scripts:

--no-git-tag-version

for eg: "npm --no-git-tag-version version major && ng build --prod"
