Online Comic Poster for Discord

Setup

• Make sure you have node installed.
• Install the required dependencies npm i.
• Make sure the code has permission can write to data.json.
• Update data.json to have the key items.
• Run index.js in a terminal via node index.js
• go to your comic's domain page and find a way to access the latest comic every single time. (generally homepage) Then go into websiteHandler.js and edit:
  • getCurrentPageImgLink - To grab the page's IMAGE url,
  • getCurrentPageDifferential to extract the info from the page that tells it whether this page is different from the last(I recommend date).
  • getDownloadLocation to tell the handler what is the link to extract the data from. (use the passed in object to store incrementals in case the link changes whenever a comic is posted, Eg: comic/page1.html, comic/page2.html, comic/page3.html)
  • comicWasPosted to add to any increments in case website's link changes per comic.
• If you need help on the last step lemme know so I can help, it's a difficult step.

data.json

data.json needs to have these keys inside an object like so:

{
    "key":"",
    "admins":[""],
    "owners": [""],
	"updateTimer": "",
    "channelID":"",
    "debugging":true,
	"useEmailHandler": false,
    "host": "",
    "port": 0,
    "sender": "",
    "receiver": "",
    "auth": {
        "user": "",
        "pass": ""
    },
    "websiteHandlerData": {},
    "pingEveryone": 0
}

And key and channelID have to have a value.

• key The key to the Discord bot.
• admins An array of Discord User IDs. (These are users who can run the 3 commands)
• owners An array of Discord User IDs. (These are users who can run the eval command)
• updateTimer After how many milliseconds should the bot check for the comic?. (86400000 = once per day)
• channelID An ID to the channel that the bot will post the picture to.
• debugging A boolean. Changes whether the bot logs what it's doing or not.
• useEmailHandler Whether or not to try to send an email whenever the bot errors or something bad happens.
• host,port,sender,reciever, auth.user, & auth.pass are only required if useEmailHandler is set to true. If so, Further instructions are supplied later.
• websiteHandlerData can be whatever you need. It gets passed in to the websiteHandler for your customization, and is saved with every comic posted
• pingEveryone can be 0 for no, 1 for yes, 2 to ghost ping everyone.

Email Handler

You can learn more about how to use the API I am using called nodemailer.
If you decide to have useEmailHandler in the data.json set to true, the following will need to be filled out depending on your transport method:

• host the website/server with email capabilities. Looks like smtp.site.com or mail.site.com
• port the port number the email server chose to expose.
• sender what to make the sender of the email appear like.
• reciever what email to send the email to. Can be multible emails separated by commas ,
• auth The entire auth object is passed in as is to the webmailer. Most of the time auth is an object containing:
  • user username to log into the webmailer
  • pass password to log into the webmailer

Commands

The bot has 5 commands, (listed down below). To trigger one you need to start your message by pinging the bot, followed by the command. Eg: @Comic-Bot checkforComic or @Comic-Bot restart. (commands are not case sensitive)

• ping Will respond with a message saying how long the bot's been online for, and when it's next comic check is due.
• restart Will restart JUST the discord bot.
• shutdown Shuts down the entire code.
• checkForComic will check for a new comic and if one exists it will post the comic.
• eval will run any code you post AFTER the eval command.
• notif | notify will notify owners of the bot via email(if setup) and DM something is happening. Useful for emergencies or bug-reports.
• help | about | credits Will share info about the bot.
