A service for finding the closest restaurants by location

This is my first go app

Run app

To deploy the app locally you simply run make start in your cmd. To stop the app run make stop

Loading Data with ElasticSearch

All the restaurants are loaded from CSV file internal/config/data.csv and inserted into EalsticSearch storage using Bulk API for a faster performance.

Check info about the index:

curl -s -XGET "http://localhost:9200/places"

Add new restaurants: (the mapping is in internal/config/schema.json file)

curl -XPUT "http://localhost:9200/places"

You can query the restaurants by ID like this:

curl -s -XGET "http://localhost:9200/places/_doc/1"

Interface

To access the view, follow http://localhost:8888/?page=1

API

curl --request GET \
  --url 'http://localhost:8888/api/recommend?lat=55.674&lon=37.666' \
  --header 'Accept: */*' \
  --header 'Content-Type: application/json'

By default Elasticsearch doesn't allow you to deal with pagination for more than 10000 entries. To fix that, run make update_index_settings

Closest restaurants

Get JWT

Before calling API for the closest restaurants, you need go get token.

http://127.0.0.1:8888/api/get_token

That token is used for the authorization.

Get recommended restaurants

Get the closest restaurants according to the location (latitude, longitude). Don't forget to use your specific token for authorization.

curl --request GET \
  --url 'http://localhost:8888/api/recommend?lat=55.674&lon=37.666' \
  --header 'Accept: */*' \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json'
