Module for extracting Twitter data using option objects

Install

1. Install Node.js
2. Install twitter2return via npm
3. Recommended: Install dotenv via npm

npm install --save twitter2return
npm install --save dotenv

For the latest developer version, see Developer Install.

Usage

It is recommended to use a .env file at the root of your project directory with the following contents:

• Obtain the keys below from https://apps.twitter.com/
• TWITTER_CONSUMER_KEY: Consumer key (API Key)
• TWITTER_CONSUMER_SECRET: Consumer secret (API secret)
• TWITTER_ACCESS_TOKEN_KEY: Access token
• TWITTER_ACCESS_TOKEN_SECRET: Access token secret

TWITTER_CONSUMER_KEY=***
TWITTER_CONSUMER_SECRET=***
TWITTER_ACCESS_TOKEN_KEY=***
TWITTER_ACCESS_TOKEN_SECRET=***

The .env file above can be loaded using dotenv:

require('dotenv').config();

See Documentation for more details.

REST API

1. Load .env file variables
2. Load twitter2return
3. Create options object
4. Optionally define Twitter API keys
5. Search keyword twitter from GET search/tweets
6. Apply a jsonata filter for statuses key only
7. Execute twitter2return with the REST API options

require('dotenv').config();

var twitter2return = require('twitter2return');

// (options) Initialize options object
var options = {twitter: {}};

// (options_twitter_rest) Search for keyword 'twitter' in path 'GET search/tweets'
options.twitter.method = 'get'; // get, post, or stream
options.twitter.path = 'search/tweets'; // api path
options.twitter.params = {q: 'twitter'}; // query tweets

// (options_jsonata) Filter for statuses array using jsonata
options.jsonata = 'statuses';

// (twitter2return_rest) Query tweets using REST API
twitter2return(options)
	.then(data => {
		console.log(data);
	}).catch(err => {
		console.error(err.message);
	});

Stream API

1. Load .env file variables
2. Load twitter2return
3. Create options object
4. Optionally define Twitter API keys
5. Track keyword twitter from POST statuses/filter
6. Log the tweets when they are received
7. Execute twitter2return with the Stream API options

require('dotenv').config();

var twitter2return = require('twitter2return');

// (options) Initialize options object
var options = {twitter: {}};

// (options_twitter_connection) Track keyword 'twitter' in path 'POST statuses/filter'
options.twitter.method = 'stream'; // get, post, or stream
options.twitter.path = 'statuses/filter'; // api path
options.twitter.params = {track: 'twitter'}; // query tweets

// (options_twitter_stream) Log the tweets when received
options.twitter.stream = function(err, data) {
	if (err) {console.error(err)};
	console.log(data.twitter.tweets);
};

// (twitter2return_stream) Stream tweets
var stream = twitter2return(options);
stream.on('error', function(error) {
	console.error(error.message);
});
