# or
npm install -D @invisible/publish

Usage

Programmatically

'use strict'

const {
  assertVersionBump,
  publish,
} = require('@invisible/publish')

const newRelease = async () => {
  {
    // fileName defaults to 'package.json' if no argument given.
    // This method return a promise of an object with pass and msg as keys.
    const { pass, msg } = await assertVersionBump({ fileName: 'package.json' })
    // You can process the results as you wish. As an example, you can consume it like below:
    if (msg) console.log(`assert-version-bump: ${msg}`)
    if (! pass) process.exit(1)
  }

  {
    const { NPM_TOKEN, NPMRC_DIR } = process.env

    // NPMRC_DIR defaults to 'process.env.HOME' if no argument given.
    // This method return an object with pass and msg as keys.
    const { pass, msg } = publish({ NPM_TOKEN, NPMRC_DIR })
    // You can process the results as you wish. As an example, you can consume it like below:
    if (msg) console.log(`publish: ${msg}`)
    if (pass) process.exit(0)
    process.exit(1)
  }
}
newRelease()

Hook Scripts

assert-version-bump

Add assert-version-bump to your package posttest script in package.json:

// It would look something like:
  "scripts": {
    "posttest": "assert-version-bump"
  }

You can also run it at any time from your CLI.

$ assert-version-bump # will output the change if found
$ assert-version-bump --quiet # will silently succeed, but output error if not found

• OPTIONAL: you can pass the filename as argument to assert version bump. Defaults to package.json

"scripts": {
    "posttest": "assert-version-bump manifest.json"
  }

publish

• Add publish to the commands on deployment section of your package circle.yml:

# It would look something like:
deployment:
  release:
    branch: master
    commands:
      - publish

NPM_TOKEN environmental variable is required for publishing. See Miscellaneous Information to know options on how to add it.

You can also run it at any time from your CLI. Just make sure you are on master branch and have a ~/.npmrc file with a valid token.

$ publish
$ publish --quiet # will silently succeed, but output error.

Miscellaneous Information

• Add NPM_TOKEN environmental variable to your package on circleCI.

  To do this you will have to:

  • Go to https://circleci.com/gh/invisible-tech/<your-package-name>/edit#env-vars (replace \<your-package-name>, e.g. merge-parsers)
  • Click on Import Variable(s).
  • Select NPM_TOKEN.
    • If you don't have permission to do that, ask your superior to do it!

• You can add NPM_TOKEN to your .env file and install dotenv as dependency/devDependency.

Troubleshooting

If you are having problems, it probably is because you don't have your package .bin folder set on PATH.

machine:
  environment:
    # For yarn
    PATH: "${PATH}:${HOME}/${CIRCLE_PROJECT_REPONAME}/node_modules/.bin"

Known Issues

assert-version-bump does not work on the first PR because it asserts through diff of HEAD and last merge commit.

TODO

Make assert-version-bump work since first PR.
