This is a Node.js client for flying-sphinx.com (initially just as a Heroku add-on, but support for other platforms will be added in the future). Consider it a beta at the moment: the functionality’s there, though you may need to read the source a little.
flying-sphinx package is available via npm:
npm install flying-sphinx
If you’re not familiar with Sphinx, then this isn’t the place to start… but once you understand how Sphinx works, there’s a few key areas to interact with Flying Sphinx: configuration of Sphinx, processing the indices, and starting up and stopping the daemon.
Authentication credentials are sourced from the environment (FLYING_SPHINX_IDENTIFIER and FLYING_SPHINX_API_KEY) – and these are automatically available through Heroku. If for some reason you wish to run commands locally, then you’ll need to make sure those two settings are in place.
To get your Sphinx configuration file loaded, you’ll need send the file through to Flying Sphinx. This can be done from the command line via Heroku:
$ heroku run flying-sphinx configure /path/to/sphinx.conf
var flyingSphinx = require('flyingSphinx'); var configuration = flyingSphinx.configuration(); configuration.upload('raw configuration'); configuration.uploadFromFile('/absolute/path/to/a/sphinx.conf'); configuration.uploadSettings('wordforms', 'wordforms.txt', 'file contents'); configuration.uploadSettingsFromFile('wordforms', '/path/to/wordforms.txt');
Make sure any settings file names match what you’ve set in your configuration file, but don’t stress about paths – Flying Sphinx will set them up for you. Settings files must be unique per setting – if you refer to
a.txt for wordforms in more than one place, it’ll be a single file, not scoped to index.
Now that Flying Sphinx is aware of your Sphinx configuration, you’ll want to get Sphinx processing your data. This can be done over the command line as well:
$ heroku run flying-sphinx index
If you want to process specific indices, just specify them as arguments:
$ heroku run flying-sphinx index article user
This can also be done through code if necessary:
var flyingSphinx = require('flyingSphinx'); flyingSphinx.index().run();
run can take two arguments, the first being an array of index names, the second being a callback function to run with the resulting log. They’re both optional, but if you just want a callback, specify an empty array for the first argument.
Again, easy via either the command line or through code:
$ heroku run flying-sphinx start $ heroku run flying-sphinx stop
var flyingSphinx = require('flyingSphinx'); flyingSphinx.sphinx().start(); flyingSphinx.sphinx().stop();
Via the command line, you can also use the
restart command (to stop and then start the Sphinx daemon) and the
rebuild command (to stop the daemon, process indices, then start the daemon back up).
$ heroku run flying-sphinx restart $ heroku run flying-sphinx rebuild
This library has been built and tested against Node 0.8, but I will happily accept patches for other versions of Node if necessary.
Patches are indeed welcome (especially given Node.js is not a framework I’m familiar with at the moment). flying-sphinx.com API documentation will be provided at some point in the future, but generally keep in mind the following:
- The environment is managed via npm.
- Please use the test frameworks as shown by the existing tests – and do write tests.
- Keep your commits in a separate branch.
- Don’t mess around with the version number in your branch – this keeps merges easier for me to manage.
