Question

Is there a way to store my collection data in a variable and access it externally from the file?

Topic of Interest : Working with Discord.js

I am seeking advice on how to save collector data in a variable and access it outside of the file, for example in index.js. I aim to create a setup command that prompts users with questions when they type -setup, stores their answers in variables, and uses these variables in the main file.

The three key questions I have are:

1 . How can multiple questions be presented to the user?

2 . Is it possible to save these questions in a variable for external use?

3 . What is the most effective way to determine if the setup has been completed by the user?

Current Project Scenario : I am currently developing a welcome message bot that requires manual configuration before it becomes operational on a server. Administrators must execute the -setup command which will gather details such as channel ID, custom message, invite image, etc. Once these details are provided, the bot will generate a customized embeded welcome message on the designated channel.

One final query: Is it necessary to implement a database for this functionality?

Refer to the Discord.js documentation on waiting for messages. By adjusting the filter, you can wait for a message from a specific user by comparing the sender of the command with the received message.
To convert the answers stored in a variable into text, use JSON.stringify(variable) and then utilize the fs module to save it to a file.

const fs = require('fs')

fs.writeFile('/Users/joe/test.json', variable, err => {
 if (err) {
   console.error(err)
   return
 }
 //file written successfully
})

To read from the file, simply use

var answers = JSON.parse(fs.readFileSync('file', 'utf8'));

There are various methods to accomplish this task. Storing a separate file for each user allows you to easily check the existence of a file based on the user/server id.

fs.stat('test.json', function(err, stat) {
   if(err == null) {
       console.log('File exists');
   } else if(err.code === 'ENOENT') {
       // file does not exist
       fs.writeFile('log.txt', 'Some log\n');
   } else {
       console.log('Some other error: ', err.code);
   }
});

The necessity of a database depends on the size and complexity of your bot. I personally haven't required one for my bots, but for larger projects, it may be beneficial to explore utilizing one. I've included links to more detailed explanations and resources throughout, so make sure to refer to those if you need further clarification.
