Pushing tag after npm version

I’m trying to push the latest version created via npm version to github, but the following code doesn’t work

package.json

{
  script: {
    "version": "node pushVersion.js"
  }
}

pushVersion.js

const fs = require('fs')
const packageJson = fs.readFileSync('./package.json')
const version = JSON.parse(packageJson).version || 0

const simpleGit = require('simple-git')
const git = simpleGit()

let latestTag = `v${version}`

git
  .push(['origin', latestTag])
  .exec(() => console.log('%s is on github', latestTag))

If I inject .addTag(latestTag) before .push(...) - the tag gets pushed, but I recieve an error that the tag already exist.

Getting the tags with .tags(...) will provice me a list of tags which doesn’t contain the latest version bumped by npm version.

How can I push a single tag after npm version? manually typing `git push origin <tagname> works.

That was perfect! that does exactly what I wanted to achieve. Only “issue” is the git.tags() which doesn’t return the TagList, hence tags.all fails since tagswill be undefined.

I’ve added the final setup (with corrections) here for future references:

projectRoot/package.json

{
  ...
  script: {
    "postversion": "node pushVersion.js"
    ...
  }
}

projectRoot/pushVersion.js

const simpleGit = require('simple-git')
const git = simpleGit()
const latest = `v${require('./package.json').version}`

Promise.resolve()
  .then(() => git.tags((err, tags) => tags)) // changed to return the tagList from git.tags()
  .then((tags) => {
    return tags.all.some((tag) => tag === latest)
  })
  .then((alreadyTagged) => {
    if (!alreadyTagged) return git.tag(latest)
  })
  .then(() => {
    git.push('origin') // Added to ensure everything committed is pushed as well
    return git.push('origin', latest)
  })
  .then(() => console.log('Tag "%s" is now available on Github', latest))

Do you have NPM’s git-tag-version set to false when you run npm version? If not, there should be a git tag already created in your local.

Try switching to:

const git = simpleGit();
const latest = `v${ require('./package.json').version }`;

Promise.resolve()
  .then(git.tags())
  .then(tags => {
    console.log(`Tag List: `, tags);
    return tags.all.some(tag => tag === latest);
  })
  .then(alreadyTagged => {
    if (!alreadyTagged) return git.tag(latest);
  })
  .then(() => {
    return git.push('origin', latest);
  })
  .then(() => console.log('DONE'))
;

If that’s still not working as expected - please can you run your code with debug enabled and include the relevant bit of the log in the issue
