Chicago Food Finder

The goal is to provide food options for the Chicago Area.

How this works?

• Cron

  Cron runs every hour to pull latest posts from Instagram API using a hashtag: #chicagofood. Hosted in Heroku.

• Database

  Posts are saved in a Mongo Database hosted in Atlas, which is a Cloud Provider.

• API

  A nodejs restful api hosted in Heroku, exposes the following endpoints:

  • /topics

    This endpoint analyses the latest 500 posts and with the help of LDA extracts the most trending topics found on the caption of the posts.

    It also cleans the data by removing certain words.

  • /search

    Receives a category (topic) as a query parameter and returns posts that include that topic.

  • /choice

    Saves the relation: Topic - Post chosen by the user when they click a post. In a future interation this will help to improve the /search endpoint.

• Web app

  This web app was built with sapper and it's hosted in Netlify, shows mainly three actions:

  • Topics

    Pulling the data from the API.

  • Options

    Based on the Topic chosen by the user, the app hits the API to pull options for that topic.

  • Choice

    Finally when the user clicks a post, is taken to the original publication in Instagram and at the same time the selections is saved, in a future iteration this will help to improve the search algorithm.

This is pretty much it, so in a few words:
