Liri Bot

Overview

Language Interpretation and Recognition Interface (LIRI) is a command line node application that accepts parameters and returns matching data via application programming interfaces (APIs). The resulting data is returned to the user via console.log and appended to a log file.

Features

LIRI includes four (4) features:

1. concert-this - accepts the name of a singing artist or band and returns the following concert information using the "Bands In Town" API.
   • Venue name
   • Venue location
   • Concert date, formatted as "MM/DD/YYYY"
2. spotify-this-song - accepts a song/track name and returns the following information using the "Spotify" API.
   • Artist(s)
   • Song name
   • Song preview link on Spotify
   • Album name
3. movie-this - accepts a movie name and returns the following movie information using the "OMDB" API.
   • Title
   • Year
   • IMDB Rating
   • Rotten Tomatoes Rating
   • Country where produced
   • Language
   • Plot
   • Actors in the movie
4. do-what-it-says reads the contents of random.txt, which contains the name of a LIRI feature and an input parameter, and then calls the feature using the supplied input parameter.

LIRI is launched by running one of the following commands on the command line:

• Builds a query URL with the user's input and required API key
• Makes an async call with the Axios NPM to the Bands In Town API

• Appends the response to the log.txt file

2. node liri spotify-this-song song name

LIRI Results

LIRI Bot is a command line application; accordingly, its commands cannot be run in a web browser. Therefore, I have created a website at https://plkgit.github.io/liri-node-app/ that contains screenshots of the results of each command as well as a PDF copy of the log.txt file.

Alternatively, see below for results screenshots and a PDF copy of the log.txt file after running each command.
