A Discord bot that monitors Amazon items, and notifies you on price drops/restocks
Before updating you should always check here in case of any database/config changes you may need to set.
"Why isn't this public?" you may ask. Well, the simple answer is that Amazon doesn't really like bots. When a program like this sends a ton of requests to Amazon all at once, they tend to catch on and start asking for human verification. Having 5 watched items per server, in even just 10 servers, is 50 requests every 2 minutes (not accounting for the 6-second buffer per request that is used to deter said verification). This also means that this can break at basically any moment, so if it all of a sudden stops working without any code changes, please don't make an issue for it, just maybe give the bot a rest and lower your watchlist.
Setup is easy enough. Clone the repo somewhere and create a file in the main folder (the one with index.js in it) named config.json. Fill in the contents of config.json using this:
{
"prefix":"YOUR_PREFIX",
"token":"YOUR_BOT_TOKEN",
"URLParams":{},
"guild_item_limit":5,
"cache_limit":10,
"required_perms":[],
"tld":"com",
"autoCartLink":true,
"debugEnabled":false
}Filling in the proper values of course. We'll go over each of them specifically below.
Amazon categories (eg. https://www.amazon.ca/Tablets/b/?ie=UTF8&node=2690953011) and search queries (eg. iphone) can now be watched. This will cache the entires found when first running the watch command, and will update the cache and send price alerts on subsequent price checks.
Due to this, the watch command required a bit of a rework, and now uses arguments to specify which type you are watching. Here's how it works now (assume prefix = !):
Watch a link:
!watch -l https://www.amazon.ca/dp/B0813VL2K8/
Watch a category:
!watch -c https://www.amazon.ca/Tablets/b/?ie=UTF8&node=2690953011
Watch the results of a search query (note the + instead of space):
!watch -q nintendo+switch
If you use a proxy service (preferably paid, free ones are pretty hit and miss) then you can include a proxylist.txt file in the main bot folder, where each one is separated by a newline. The file is automatically detected so there is no need for any config changes once you create/add it.
To set up the bot user, head to https://discordapp.com/developers and login. From there create a new application, set the name and image to whatever (you can change them later), and then click the "Bot" tab. Click "Add bot user" and once that's created, copy the token and place it in the config.json under "token". I doubt this has to be said, but DO NOT share your bot token with ANYONE.
You may have noticed the last value, "guild_item_limit". This value can be changed, but at the risk of being flagged as a bot and breaking everything. I don't even know if 5 is too high or low, so just... keep it as low as possible?
Due to the local storage-y nature of the watchable category and query items, it has to store some cache. If you worry about data loss, you can make this a small number, like 5 or 10. Otherwise, go nuts, I think you'll be storing at most like 30 items.
The required_perms field is an optional list of permissions that a user with be required to have for running any command that changes the watchlist in any way. You can leave this empty if you want anybody to be able to use them.
It is an array, so the format is ["permission_1", "permission_2"]. You can refer to Discord permissions here (you can use the permission name, eg "MANAGE_MESSAGES")
A Top Level Domain (or TLD) is just the .com or .ca of a URL. If you want searches to be local to your country's Amazon, say, www.amazon.de, you can set your TLD in the config to de. More examples include:
ca - Canada
co.uk - UK
com - America (default)
If you'd link for the bot to generate a link that will automatically add the item to the users cart when they click it, set this to true.
"autoCartLink":trueIf you want to include a referral code or something, you can use the URLParams object. It is formatted like this:
"URLParams":{
"ref":"my_ref_code",
"tag":"my_tag"
etc...

Now that everything is set up config-wise, you now need to install the dependancies! This can be done by running npm install inside of the root folder of the project. This should download everything you need.
Once that's done, all you (should) need to do is run node index in the root project folder and it should come to life!
Once you've got the bot running properly, you can invite it to your server by going to the OAuth2 tab on the bots application page you set up previously. Once you're there, under scopes check the box that says bot, and copy/paste the link it generates into your browser.
Google it!
Unless it's like, super broken, which then you should create an issue.
I don't expect anything from anyone, and this bot will be free forever, but if you'd like to throw a Redbull or something my way, you can do so here :)
