condition-node-version

Plugin for semantic-release that only allows publishing from a specific NodeJS version

Why?

You want to publish your module to NPM using the semantic-release task, but only if the unit tests on all Node versions pass. TravisCI does not have "build-after-all" step, see this issue and the module travis-after-all that tries to get around this. Unfortunately, this is unreliable. My builds often time out, with some builds in the matrix waiting on each other in a circle.

This is why I wrote this plugin.

Install and configuration

npm install --save-dev condition-node-version

Add the release configuration to the package.json, just like semantic-release docs show. All we need is to specify this plugin and the exact version of Node we want to publish from

"release": {
  "verifyConditions": {
    "path": "condition-node-version",
    "node": "4.2.2",
    "verbose": true // optional
  }
}

Make sure the same Node version is listed in your .travis.yml file

node_js:
  - '5'
  - '4.2.2'
  - '0.12'
after_success:
  - npm run semantic-release

Note that we no longer have to wait on multiple travis jobs, thus it is simple after_success call.

To combine this plugin with Travis environment check use a list of plugins. For example, to check Travis environment and Node version

npm install --save-dev @semantic-release/condition-travis

Then list the plugins in package.json

"release": {
  "verifyConditions": [
    {
      "path": "@semantic-release/condition-travis"
    }, {
      "path": "condition-node-version",
      "node": "4.2.2"
    }
  ]
}

You can use semantic ranges in the condition, for example

"release": {
  "verifyConditions": [
    {
      "path": "condition-node-version",
      "node": ">=4.2.0"
    }
  ]
}

The check is done using semver.satisfies.

Notes

Because the module can be published from a single version of NodeJS, while the other version builds break, you should keep the CI build green to make sure a published version of your module is really working for everyone.
