LIRI (Language Interpretation and Recognition Interface)

LIRI is a command line Node application that takes in parameters (via command line arguments or file input) to display tweets, songs from Spotify, and movie information from OMDB.

LIRI Commands

node ./liri [movie, spotify, tweets, do] <value> (--say)

Command Value Options Example Description
movie "movie title" --say node liri "Blade Runner 2049" --say Display movie information from OMDB. If host environment is macOS/Darwin, the --say flag will convert the plot text to audible speech.
spotify "song title" - node liri "Thriller" Display song information from Spotify. The default song is "The Sign" if no value is entered via the command line.
tweets twitter handle - node liri "jeffreylowy" Display 20 tweets from Twitter. The default account is @barackobama if no value is entered via the command line.
do-what-it-says - - node liri do-what-it-says Run whatever command and value are saved to the random.txt stored in the commands directory

You can also run via npm scripts.

npm run [movie, spotify, tweets, do] <value>

--say currently does not work when run via npm script.

API Keys

Rather than include a keys.js file, I used the dotenv package to create environment variables. The .env file is the first file required in ./liri.js, which stores environment-specific variables in the form of NAME=VALUE.

Replace XXXXXX with the key/secret/token for each service.

OMDB_API_KEY=XXXXX
SPOTIFY_CLIENT_ID=XXXXX
SPOTIFY_CLIENT_SECRET=XXXXX
TWITTER_CONSUMER_KEY=XXXXX
TWITTER_CONSUMER_SECRET=XXXXX
TWITTER_ACCESS_TOKEN_KEY=XXXXX
TWITTER_ACCESS_TOKEN_SECRET=XXXXX

process.env now has the keys and values defined in the .env file

// Line 16 in ./commands/twitter.js
let twitter = new Twitter({
    consumer_key: process.env.TWITTER_CONSUMER_KEY,
    consumer_secret: process.env.TWITTER_CONSUMER_SECRET,
    access_token_key: process.env.TWITTER_ACCESS_TOKEN_KEY,
    access_token_secret: process.env.TWITTER_ACCESS_TOKEN_SECRET
});

For more information, visit the NPM page for the dotenv package.

Make LIRI speak

If Node is running on macOS/Darwin, you can make LIRI read movie plot information by passing the --say flag after the movie's title. This only works when the full command is entered.

Example: node ./liri movie "Blade Runner 2049" --say

Install and run via NPM

This project was uploaded to NPM under the package name liri-cli. Though I hope to get there, the package is not yet ready to be installed globally.

Install: npm i liri-cli

--say currently does not work when run via npm script.
