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
