Standby is an incredibly simple server that just delivers a page saying your site will be back shortly. That's all!
Use it in your deployment scripts to put up a placeholder page on the port number of your node app while you are migrating data or performing other tasks that can't be done while the site is up.
The standby page will automatically refresh until your site comes back.
The URL in the browser does not change, so the user typically gets the page they wanted once the site is back up.
npm install -g standby
To display a standby page on port 3000:
standby start 3000
To stop displaying a standby page on port 3000:
standby stop 3000
To substitute your own static content in place of our standby page:
standby start 3000 --content=/path/to/my/assets/folder
The page displayed to the user will be index.html in the content folder.
Note that you need to stop standby before launching your app again.
Standby uses files in /tmp/standby to keep track of what's already running. We use /tmp rather than /var/run because we hardly ever launch node apps as root.
You need node and npm, of course. That's about it.
Althogh you can use standby without it, we had stagecoach in mind when we wrote it. stagecoach makes it easy to deploy one or more node apps to an Ubuntu server without a lot of fuss. standby is a good companion piece for use during temporary downtime such as during data migration.
standby was created at P'unk Avenue for use with sites built on Apostrophe, an open-source content management system built on node.js. If you like standby you should definitely check out apostrophenow.org. Also be sure to visit us on github.
