some questions about this Bot

[LeonardoDavid]

Hi, This Bot is very useful for me i have few question about this bot

1. can i post tweets without images?
2. is it possible to create White list and Blacklist for search query
3. how can i search based on location

[analog-nico]

Hi @LeonardoDavid I am glad you like it. Be careful how you use it or you get shut down by Twitter instantly.

1. Just remove the code for the media upload in reply.js.
2. The database is a blacklist of Twitter users. You may add users yourself beforehand. Or what kind of white-/blacklist are you looking for?
3. You would need to extend the code to add a geocode parameter like for lang.

Hope that helps.

Hi, analog-nico Thanks for your replay i have few more doubts

1. i am running this bot on my windows pc, right now i am able to run only one bot at a time is it Possible to run more than one bot at a time. i created a new bot for a different twitter account when i run it i get this error message.

events.js:85
      throw er; // Unhandled 'error' event
            ^

2.How to deploy this bot to google cloud

[analog-nico]

Regarding 1 just remove this code and then you can run multiple bots locally.

Regarding 2 you have to find out yourself I am afraid of.

[LeonardoDavid]

Hi, Thanks for the answers, to prevent the Bot from reaching twitter api rate limits, i think we can add muliple api keys and rotate the Api keys every 15 minutes the bot runs is it Possible if yes, can you tell me how

[analog-nico]

Please read the Don't spam! section of the README. It links important sources that allow you to decide if you are heading in the right direction.

As far as I can tell you are underestimating Twitter's spam detection mechanisms and want to push the amount of replies too far. For that I can no longer be your accomplice. I am sorry.

[LeonardoDavid]

i am not trying to spam anyway thank you for your time

[analog-nico]

It is good to hear that you have good intentions. Happy coding!

[LeonardoDavid]

i am learning to code for about an year i am beginner in Python and JavaScript, could suggest me any tutorial for the last question i asked you

[analog-nico]

Mmh, good question. I learned a lot from the free material of https://teamtreehouse.com back in the day. If you sign on for a free trial you may find good courses about node.js. Or ask Reddit.

[analog-nico]

Hey buddy, if you promise me you don't spam then you may find the answer to key rotation in this issue: https://github.com/analog-nico/twitter-reply-bot/issues/2

[LeonardoDavid]

Hi, Thank you

[LeonardoDavid]

i wanted to Post Tweets Without Images, like you said i removed Media Upload code in replay.js but i am getting a error when i am running this here is the Error Message

Here is my reply.js code

'use strict';

var BPromise = require('bluebird');
var Twitter = require('twitter');

var client = new Twitter(require('../settings.json').twitter_api);

module.exports = function (compiledTweet) {

    return new BPromise(function (resolve, reject) {

        var data = require('fs').readFileSync(compiledTweet.image);

            if (err) {
                reject(err);
                return;
            }

            console.dir(media);

            if (!media || !media.media_id_string) {
                reject(new Error('Image upload failed.'));
                return;
            }

            var status = {
                in_reply_to_status_id: compiledTweet.replyTo,
                status: compiledTweet.text,
                media_ids: media.media_id_string
            };

            client.post('statuses/update', status, function (err, tweet, response){

                if (err) {
                    reject(err);
                } else {
                    console.dir(tweet);
                    resolve(tweet);
                }

            });

        });

    };

[analog-nico]

"Cannot read property 'text' of undefined" means that you access the property .text of a variable that is undefined. If you search your code for "text" you find "compiledTweet.text". That means compiledTweet is undefined.

[LeonardoDavid]

hi, can you give me link to the Twitter API Library you used

[analog-nico]

https://www.npmjs.com/package/twitter

[LeonardoDavid]

Hi, to import random twitter API Keys i replaced credential code in request.js

var twitter_api= require('../settings.json').twitter_api;

var credentials = twitter_api[Math.floor(Math.random()*twitter_api.length)];  

But i am getting this error Unhandled rejection Error: [object Object]

[analog-nico]

You may use process.on('unhandledRejection', ...) to catch the rejection and look into its cause.

[LeonardoDavid]

Hey, Thanks for Helping, Sorry, i did not posted full error messages last time These are the errors i am getting

i searched google found solution for few but i dont know which code i need to change

[analog-nico]

Granted, the stack trace doesn't help. The issue is that somewhere in the context of a Promise an Error is thrown. The Promise, however, has no .catch(...) handler. Thus an "unhandled rejection" is produced.

If you can solve this you definitely improved your JavaScript skills by a big step!

[LeonardoDavid]

can you tell me which code and which line i need to fix

[analog-nico]

Take that as a challenge to improve your skills. You can do it!

Best way to approach this is to get a debugger running. Webstorm contains a very user friendly one.

HI, i have been trying for 2 days i still cant figure out whats wrong. i think my code for importing random keys might be wrong

is the code is right or wrong

'use strict';

var request = require('request-promise');
var _ = require('lodash');

//var credentials = require('../settings.json').twitter_api;
var twitter_api= require('../settings.json').twitter_api;

var credentials = twitter_api[Math.floor(Math.random()*twitter_api.length)];

function getRequestOptions(options, includeUserToken) {

    _.assign(options, {
        oauth: {
            consumer_key: credentials.consumer_key,
            consumer_secret: credentials.consumer_secret
        },
        headers: {
            'Accept': '*/*',
            'Connection': 'close',
            'User-Agent': 'node.js'
        },
        json: true
    });

    if (includeUserToken) {
        _.assign(options.oauth, {
            token: credentials.access_token_key,
            token_secret: credentials.access_token_secret
        });
    }

    return options;

}

module.exports = function (options, includeUserToken) {

    options = getRequestOptions(options, includeUserToken);

    return request(options);

};

[analog-nico]

Since your random key importing works well - I tested it - the error is produced somewhere else.

Whatever your error is it should have been caught here. I get the impression you somehow changed the code in other parts that at least screwed the promise chains up so that the error doesn't get caught properly but instead results in an Unhandled rejection.

To get more insights into your error add these lines to server.js right below the require statements:

BPromise.onPossiblyUnhandledRejection(function (err) {
    console.dir(err);
});

Instead of "Error: [object Object]" you should see now the contents of the object. Or even better, use your debugger, put a breakpoint on the console.dir line, and take a closer look at err when the execution stops there.

Use your debugger to step through everything and with that zero in on the cause! If you want to improve your debugging skill in general this book is a real gem: https://www.amazon.com/Debugging-David-J-Agans-ebook/dp/B002H5GSZ2 It is one of a handful books which really stand out from all the books I read in my life!
