Simple Autocomplete Service

A Node.js app that uses an attached Redis database to provide an autocomplete API for data uploaded as text files. Multiple separate autocomplete indexes are supported.

The autocomplete API is CORS-enabled, so that it can be accessed from any web page and conforms to the jQuery autocomplete standard.

API

GET /api

Returns a JSON array of autocomplete indexes that are available

e.g.

[]

or

["animals","trees","actors"]

GET /api/:name?term=

Parameters

  • term - the search term to autocomplete

Returns a JSON array of possible autocompletions

e.g.

["Pedro","Pejman Montazeri","Pepe Reina","Pepe","Per Mertesacker","Peter Odemwingie"]

POST /api/:name

Parameters, one of:

  • file - the text file containing a list of items to be added to the auto-complete index
  • or, url - the url of the file containing a list of items to be added to the auto-complete index

N.B the form type needs to be enctype="multipart/form-data"

DELETE /api/:name

Delete the named autocomplete index.

Lockdown mode

If you have uploaded your content into the Simple Autocomplete Service but now want only the GET /api/:name endpoint to continue working, then you can enable "Lockdown mode".

Simply set an environment variable called LOCKDOWN to true before running the Simple Autocomplete Service:

export LOCKDOWN=true
node app.js

or set a custom environment variable in Bluemix.

This prevents your data being modified until lockdown mode is switched off again, by removing the environment variable.
