Introduction

Getting Started

To install locally run npm install

You should have a MongoDB instance available and the Yelp database loaded. This demo database is not included in this repository due to the size.

Create a .env file which contains the connection credentials to your local MongoDB instance (see dotenv). The contents of the file should be similar to the following:

    DB_HOST=127.0.0.1
    DB_PORT=27017
    DB_NAME=yelp
    DB_USERNAME=webuser
    DB_PASSWORD=webpassword

To run node app.js

Creating Indexes and Other Setup Tasks

Text Search example requires an index. Create one from the shell using:

db.business.createIndex({name:'text'})

GraphLookup benefits greatly from a single field index. Create one from the shell using:

db.users.createIndex({user_id:1})

For Geospatial queries to work, a schema change is needed. A special 2dsphere index needs an object that adheres to the GeoJSON standard. For this you will need to execute our helper script that will copy the longitude and latitude fields into an object called location. Inside location we will have a type: "Point" and an array called coordinates with the longitude and latitude as the only 2 elements.

node config/yelp_prep.js

This will run against all 174K docs under the business collection. Once this completes you can now create the 2dsphere index. Create one from the shell using:

db.business.createIndex({location:'2dsphere'})
