New in v3.0: SMS / Text notification support 📱 !! (see SMS)

New in v2.0: 📧 E-mail notification support and an user interface 💻 (see screenshots)

StockAlertBot

Faced with the scenario of scalpers using bots to hog up all the inventory of popular holiday toys and sell them at ridiculously high markup prices, I decided to put up a fight so we can get our hands on things we want need to survive the #Coronavirus quarantine(s).

Of course, this is only half the battle. For full writeup on scoring items, look here.

Donate, buy me a Pizza or PayPal me if you'd like to see this project expanded and support me. :)

How does it work?

Enter links of the products you want tracked and how often you want the program to check if those products are in stock. When an item becomes available, you may configure it to notify you through variety of alerts including sound, email, discord and slack notifications, SMS / Text, console, automatically opening the URL in your browser, and more to come.

What stores/websites are supported?

Currently, the following stores are supported:

• AntOnline
• Amazon (fails at low interval rates, see proxies)

Prerequisites

0. A Terminal: (cmd (Windows), Terminal (macOS), or Console (Linux))
1. Install Node.js, either LTS or Current.
2. Clone or download this repository git clone https://github.com/PrinceS25/StockAlertBot.git
3. Go to root directory cd StockAlertBot
4. Install npm packages via a terminal npm install

Usage

There are only two steps to use this program: 1) enter information and 2) launch the program.

1. You can now enter information using two ways: via a browser (recommended) or a text editor.

   Via Browser

   1. At the root directory, run on the terminal: npm run settings
      A browser window should open up. If it doesn't and the console says Server started!, go to: http://localhost:3250/ in your browser.
   2. Enter the links of the items you want to track in the URLs tab.
   3. Go to Settings tab and change to your heart's content.
      • If you want to use Proxies, turn it on and create a file called proxies.txt in the root directory and fill it with one proxy per line. See proxies.
      • If you have Amazon link(s), you will see a options to put delay between Amazon items and pick a region. Select a region if you want to only monitor items sold by Amazon and not third party sellers. If you want to use a particular seller or if your region is not in the list, select Custom and provide the merchant ID. See Feedback and Support if you'd like to request a region.
      • If you have Target link(s), you will see additional options to put zip code and API Key. Only change the key if you get API key errors. Refer to the instructions in the following section.
   4. Configure notification options in Optional tab.
      • If you want notifications sent to Discord, IFTTT, or Slack, expand WEBHOOKS and enter the webhook URL(s) there.
      • If you want notification sent via SMS/Text, expand SMS and choose a method: Amazon Web Services, Email, or Twilio. See SMS.
      • If you want notifications sent to Email, turn on email and enter your service provider information. Some providers (Yahoo, AOL, AT&T) cause problems. Refer to this section.
   5. Once you're happy with the settings, click Save Settings.
      config.json and .env files should now reflect your settings.
      You can use CTRL + C or CMD + C to stop the program.
      
      

   Via Text Editor

   Open and edit config.json

   1. Add urls of products in the URLS array
   2. Change the INTERVAL to suit your desires.
      WARNING: Having the interval too low might have negative consquences such as this program being detected as a bot (Amazon), or blocking your IP from accessing the website. See proxies.
   3. Set OPEN_URL to false if you don't want the application to automatically open urls when item is in stock
   4. Set ALARM to false if you want to disable the audible warning
   5. Optional Settings.
      1. If you're planning to track more than one Amazon item, set the delay (in seconds) between items by editing AMAZON_DELAY. Otherwise, Amazon may flag the program's requests as a bot. You can also set a merchant ID in AMAZON_MERCHANT_ID to only get prices from a ceratin merchant. The other method allows you to select pre-configured IDs items only sold by Amazon depending on the region.
      2. If you're planning to track Target item(s), enter your zip code in TARGET_ZIP_CODE.
         NOTE: If you encounter an error relating to API Key, you need to get this key yourself:
         1. Go to target.com with the DevTools (Chrome) or Developer Tools (Firefox) open (Google or ask if you're unsure how)
         2. On the console, you should see GET requests as you load the page.
            In DevTools, you have to click the gear and check "Log XMLHttpRequests" to see them
         3. Click on any of the urls that has the string "key=" and copy the whole key
         4. Paste it to TARGET_KEY
      3. If you want to send alerts to webhook URL(s) like Discord, IFTTT, or Slack, add them to WEBHOOK_URLS array.
      4. If you want to use Proxies, change PROXIES to true and create a file called proxies.txt in the root directory and fill it with one proxy per line. See proxies.
      5. If you want to send alerts to SMS, change SMS_METHOD to either "Email", "Amazon Web Services", or "Twilio". Then change the associated values in .env. See SMS.
      6. If you want to send alerts to email, change EMAIL in config.json to true. Make a copy of example.env and rename it to .env. Inside .env, type out one of the service providers (EMAIL_SERVICE) listed in Email, your email (EMAIL_FROM) and password (EMAIL_PASS) and the email you want alerts sent to (EMAIL_TO). All without quotes.

2. Execute and continue about your day: npm start OR node --experimental-modules main.js
   You can use CTRL + C or CMD + C to stop the program.

NOTE: If you receive the error: 535 5.7.0 (#AUTH005) Too many bad auth attempts, most likely you are using Yahoo for the email server or an email server managed by Yahoo, such as AOL or AT&T. Yahoo has implemented an option that by default, does not let 3rd party products access the email servers. To resolve, go to https://login.yahoo.com/account/security and then enable the option to allow apps that use less secure sign in. Use the password generated by "Generate app password". If you are using AOL, do the same thing, from https://login.aol.com/account/security.

SMS

SMS / Text support is now available via Amazon Web Services, Email, or Twilio. This, however, requires some setup on your part. Read below regarding setup for each method:

• Amazon Web Services
  First, read pricing information here. First 100 SMS are free for each month as long as you send them to a United States destination. For this method, you will need:

  • Region
  • Access Key
  • Secret Access Key
  • Phone Number

  Region is Amazon server you want to send from. It's probably best to choose one closest to you. More information here.
  Access Key and Secret Access Key can be obtained following instructions in this tutorial.
  Phone number is the number to send SMS to. You will need to include country code and area code. Country code information can be found here.

• Email
  FREE but limited. Uses email to send text via phone carrier's SMS gateway. Mostly the same setup as Email.
  Currently supported carriers: Alltel, AT&T, Boost Mobil, Cricket Wireless, FirstNet, Google Project Fi, MetroPCS, Republic Wireless, Sprint, Straight Talk, T-Mobile, Ting, U.S. Cellular, Verizon Wireless, Virgin Mobile.
  If you'd like to request a carrier, please refer to Feedback and Support and provide your carrier's SMS gateway if possible.

• Twilio
  First, read pricing information here. You get some free starting balance with which you can buy a Twilio phone number. For this method, you will need:

  • Twilio Account SID
  • Twilio Auth Token
  • Twilio Phone Number
  • Phone Number

  The first three can easily be obtained from the Twilio console after you make a Twilio account.
  Phone number is the number to send SMS to. You will need to include country code and area code. Country code information can be found here.
  
  

Proxies

If you plan to use low interval rates OR track several items from one store, it is highly recommended that you use proxies such as ones from Webshare in the format ip:port for IP-based authentication or username:password@ip:port.

NOTE: The following stores do not currently with proxies due to them blocking some connections/headers which results in inconsistent connection: Argos, Best Buy, Costco, and Tesco. Thus we thought it'd be best if we take off proxy support for now until we can do some further research or find an alternative way.
