Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

Quick rundown of the Discord bot verification situation.

Remember, there's not rush to get verified before October 7th, since verification takes about 5 days anyways. If you are in less than a 100 servers, no need to worry, your bot will still work as it does currently. Keep in mind some stuff is NOT official, so unless there's a source, take it with a grain of salt.

Verification

• If you are in a team, the owner gets verified, which verifies the whole team. Source
• If you can't provide ID verification, you could transfer ownership of your team to another member so they can do the verification process. Source
• The Stripe verification piece is on the user itself, but the other parts of the form are per-bot.
• You do NOT need a Stripe account to verify, only your ID. [Source](https://discordapp.com/channels/613425648685547541/6972

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

How to be a good programmer

Step 1: Use a good programming language, like PHP, everyone loves PHP!

Step 2: Write a library that's useful! If you think it is, then it is, regardless of what others say, they only have more experience, what could they know?

Step 3: Use a good coding style, name your variables to something that is completely the opposite of what the variable actually is, this way you'll prevent evil hackers from stealing your code!!!

Step 4: Don't bother indenting, it's a waste of precious bytes on your harddrive and a wate of your precious time!
