用 NodeJS 進行 Twitter 情感分析

const Twit = require('twit');

const dotenv = require('dotenv');

const sentiment = require('sentiment');

const colors = require('colors/safe');

dotenv.config();

const { CONSUMER_KEY

, CONSUMER_SECRET

, ACCESS_TOKEN

, ACCESS_TOKEN_SECRET

} = process.env;

const config_twitter = {

consumer_key: CONSUMER_KEY,

consumer_secret: CONSUMER_SECRET,

access_token: ACCESS_TOKEN,

access_token_secret: ACCESS_TOKEN_SECRET,

timeout_ms: 60*1000

};

let api = new Twit(config_twitter);

function get_text(tweet) {

let txt = tweet.retweeted_status ? tweet.retweeted_status.full_text : tweet.full_text;

return txt.split(/ |\n/).filter(v => !v.startsWith('http')).join(' ');

}

async function get_tweets(q, count) {

let tweets = await api.get('search/tweets', {q, count, 'tweet_mode': 'extended'});

return tweets.data.statuses.map(get_text);

}

async function main() {

let keyword = 'avengers';

let count = 100;

let tweets = await get_tweets(keyword, count);

for (tweet of tweets) {

let score = sentiment(tweet).comparative;

tweet = `${tweet}\n`;

if (score > 0) {

tweet = colors.green(tweet);

} else if (score < 0) {

tweet = colors.red(tweet);

} else {

tweet = colors.blue(tweet)

}

console.log(tweet)

}

}

main();
