Jeopardy-API

This is an example repo for creating a simple API with Loopback, Elasticsearch, and Jeopardy!

####Setup

For this example, you need to have/install:

node 6 (^6.6.0)
npm 3 (^3.10.3)
loopback (^2.22)
loopback-component-explorer (^2.7)
loopback-connector-es (^1.3) -- go star this repo now!

To install loopback-connector-es, use:

npm install loopback-connector-es --save --save-exact
Install Elasticsearch
Install the ICU analysis plugin

sudo bin/plugin install analysis-icu

(If you were running Elasticsearch, restart it)
To start Elasticsearch: ./bin/elasticsearch

Data

The Jeopardy! dataset (>200K questions/answers) is available here.

Put the downloaded data in the /data directory and update the paths in the scripts in the /scripts directory.

Running

This example includes:

a Question model
a datasource (db) for Elasticsearch
an analyzer file for Elasticsearch
a mapping file for Elasticsearch
remote methods for Random and Search methods
scripts to create an index, add mappings, and load data

To get started:

start Elasticsearch ./bin/elasticsearch
update the $PATH in scripts/load-mapping.sh to be the full path to those files/directories
run bash scripts/put-mapping.sh

This should create an index in Elasticsearch for you. Then:

npm install (if you haven't already)
start the server: node server/server.js
open up the Explorer: http://0.0.0.0:3000/explorer
start playing!

If you want to add more documents to your index:

make sure you've downloaded the Jeopardy! dataset and saved it to the /data directory
install jq
update the $PATH in scripts/load.sh to be the full path to those files/directories
update the LIMIT and COUNTER in scripts/load.sh do NOT try to load all 200K questions with this script
run bash scripts/load.sh
