Cities Search

This repository creates a service to search cities using the jaro-winkler algorithm

Run npm i to install al dependencies

ENV variables required

• JARO_WINKLER_THRESHOLD: this one defines the default threshold for string comparision, every string with a value greater will be in the response
• SERVER_PORT: If this variable is not set, port 4000 will be set as default

Testing queries:

Search with no results

query {
  Cities(
    search: "SomeRandomCityInTheMiddleOfNowhere"
    minimumScore: 0.75
  ) {
    city {
      name
      lat
      long
    }
    score
  }
}

Search with results, and using default score threshold

query {
  Cities(
    search: "Lond"
    #minimumScore: 0.75
  ) {
    city {
      name
      lat
      long
    }
    score
  }
}

Work to do

• Generate a proper database to allow dynamic data insertion
• Validate used algotithm performance and replace it if needed
• Custom error validation, by now we depend on graphQL validations
