version-middleware

Express.js middleware that returns NPM version and Git SHA

NPM

Build status semantic-release js-standard-style

Use

npm install --save version-middleware

const version = require('version-middleware')
app.get('/version', version())

Then GET /version, returns JSON with

{
  "version": "...",
  "git": "short SHA",
  "started": "Date ISO string"
}

The returned JSON data will have cache-control header that prevents any caching on the client

cache-control: max-age=0, no-cache, no-store, no-transform, must-revalidate

Pass send

If you do not want to assume res.send function, you can pass send function to be called with results. For example when using micro server you send result using send function.

const {send} = require('micro')
const version = require('version-middleware')()
micro(async(req, res) => {
  version(info => {
    send(res, info)
  })
})

Built version file

You can save build information during CI test run using built-version into file build.json. If this file is found, it will be used instead of getting Git sha and reading version from the package.json file.
