Often we need to embed last commit id
into the server information to enable efficient debugging. Since the code is often executed
on a separate instance without the any Git information (like Heroku), we need other means
for saving the last commit repo. I suggest in [this blog][1]
saving the commit id into a separate file during the CI build and then sending the file
to the hosting environment where it can be loaded on startup.
This package can do both: save and read the last commit.
npm install --save last-commit
Run this module as a stand alone tool using NPM script to save the last git commit id
``json`
"scripts": {
"last": "last-commit"
}
npm run last
This will create the build.json file with the last commit id. Deploy it with the
rest of the code (See [1][1] how) and read it when starting the application
When starting the application, use this module's exported function that will try:
* get last commit using git
* read from build.json
In both cases shorten id will be returned, but the build.json will contain the
full one.
Example: embed the commit id in the Express server
`js`
var getLastCommitId = require('last-commit');
getLastCommitId()
.tap(function setCommitId(id) {
app.set('commit', id);
})

If running on Heroku, the last deployed commit SHA is available
under SOURCE_VERSION` variable. This module will return it if found.
