What's Cooking with Atlas Search

A Restaurant Finder Application Demo MongoDB Atlas Search

Hello! 👋 This application allows you to search lightning fast through over 25,000 restaurants in the New York city area based on a variety of search parameters and data types:

• restaurant name
• geolocation coordinates
• cuisine type
• average star rating
• borough

Note: This dataset is mocked. Please do not use to make actual dining decisions.

What's Cooking implements many Atlas Search features from autocomplete to custom function scoring. Using the $search operator in a MongoDB aggregation pipeline, we can build fine-grained searches across text, numerics, and geospatial data. By building out What's Cooking, you'll learn all sorts of ways MongoDB allows you to build complex, fine-grained full-text searches on your Atlas data.

No additional servers or software needed. No need to keep data in sync. Everything is done in MongoDB Atlas.

• fuzzy matching
• highlighting
• autocomplete
• range queries
• geoqueries
• facets
• relevance-based scoring
• custom function scoring
• synonyms

Check out the video of the MongoDB.Live keynote to see a demonstration of all the features or visit the link below to play around with the finished application, hosted entirely in MongoDB Atlas:

www.atlassearchrestaurants.com

This application is hosted entirely by MongoDB Atlas was created using:

• React
• Tailwind CSS
• MongoDB Realm for backend HTTPs endpoints and webhooks
• A modified sample dataset based on MongoDB's Atlas sample_restaurants dataset

Currently this app is not suitable for mobile, but feel free to send a PR. 😊

Prerequisites

• A MongoDB Atlas account. Get one for free here.
• A recent version of Node.js and npm.
• Restaurant sample dataset.
• Synonyms dataset.
• (Recommended) MongoDB Compass - GUI

You can read and download the dataset using the MongoDB Shell, any MongoDB driver, or my favorite MongoDB Compass using the following URI:

  
mongodb+srv://mongodb:atlassearch@shareddemoapps.dezdl.mongodb.net/whatscooking

It is also included in this repo's Supplemental Files branch as

whatscooking.json

To Build This Application...

Prepare Data

1. Load data to Atlas cluster:
   • database: whatscooking
   • collection: restaurants, menu_synonyms
2. Create Search indexes. (Index definitions includes in indexes directory.)

Deploy HTTPS Endpoints at your own env

1. Create Application
At your Atlas UI, click Create a New App
Name your application whatever you wish.
After ensuring it is linked to the correct cluster, click the CREATE APP SERVICE button.
2. Create HTTPS Endpoints
Go to HTTPS Endpoints at navigation bar at left and click Add An Endpoint
Create following 3 HTTP endpoints


Route	Source code of function	HTTP methods	Respond With Result	Return Type
/restaurants/getRestaurantsAutocomplete	_backend_functions/getRestaurantsAutocomplete.js	GET	Enable	JSON
/getRestaurants	_backend_functions/getRestaurants.js	POST	Enable	JSON
/restaurants/getFacets	_backend_functions /getFacets.js	POST	Enable	JSON
/synonyms/getFoodSynonyms	_backend_functions/getFoodSynonyms.js	POST	Enable	JSON

Please keep default value for other options and click Save Draft

3. Function Setting
Go to Function at navigation bar at left
At each function which you created, go to Settings tab, choose System at Authentigation and click Save Draft
4. Deploy app
At the top of UI, click REVIEW DRAFT & DEPLOY

🚧

To Run This Application....

1. Clone the repo.
2. Navigate inside WhatsCooking directory.
3. Run npm install .
4. Change HTTPS endpoint urls at src/hooks/useHomeFetch.js to your own ones.
5. Change HTTPS endpoint urls at src/compenents/SearchBar.js to your own one.
6. Change MongoDB Connectionstring at src/pages/IndexPage.js to your own one.
7. Run npm start .

To Deploy Frontend to AWS S3...

1. Make sure that you're using NodeJS v16 to successfully build the artifacts. If you're using nvm to manage your Node version, just type nvm use to swich to the correct NodeJS version
2. Set AWS temporary credentials in your environment variable and ensure that you're pointing to the correct AWS account
3. Run ./deploy_to_s3.sh
4. The S3 bucket is fronted by CloudFront, so it might take a while for the cache to be refreshed. If you want invalidate the cache manually, following the instructions when you run the script

React Components....

Using Realm as Your Serverless Backend....

What's Cooking uses HTTP services in Realm to create 5 APIs to allow you to query for your restaurant data over HTTP:

• GetRestaurantsEndPoint called from the useHomeFetch.js hook.
• GetFacetsEndpoint called from the useHomeFetch.js hook.
• Suggestions_AC_Endpoint called from the SearchBar.js component.
• getSynonyms called in the SynonymsPage.js.

Find the Realm application and code for these webhooks in the WhatsCookingRealm folder.
