Upgrading from djs v12 (commando) to djs v14 (and sapphire framework) - Unsure on how to Parse Types

Hello! I have recently started upgrading an outdated open source project, and got stuck for a couple days on a specific aspect (almost done with everything else though). Context: In the configuration command, it takes two arguments, first being the key (or what setting to change), and second being the new value. Problem: The old project had a parseType function (under Utils.ts), which uses Commando's ArgumentCollector and ArgumentInfo - these do not exist in vanilla dj.s v14 or Sapphire Framework. This parseType function is extremely crucial, as it checks if the VALUE input is valid for the config (ex. councilorRole would take a role mention or role ID, and the parseType would return the Role object IF VALID somehow?). This function also takes a custom serializer that tells it the Object type and how to serialize/what function to run (ex. councilorRole key has type "role" for value, and runs the getId function). I am unsure on how to move forward with this, I have a working serializer (at least I believe) that hasn't been changed, but I am unsure on how to return the object. Depending on the key, the value could be anything from a boolean, role, channel, or JSON. The original project & files in question: command (line for parseType) https://github.com/evaera/Votum/blob/581f213f84786296f35d418f52178226e8cd2561/src/commands/votum/ConfigCommand.ts#L112 parseType: https://github.com/evaera/Votum/blob/581f213f84786296f35d418f52178226e8cd2561/src/Util.ts#L71 serializer that is fed: https://github.com/evaera/Votum/blob/581f213f84786296f35d418f52178226e8cd2561/src/commands/votum/ConfigCommand.ts#L88C4-L88C4 the actual serializer that is imported: https://github.com/evaera/Votum/blob/581f213f84786296f35d418f52178226e8cd2561/src/CouncilData.ts#L83 Will post my ConfigCommand.ts file below! - Utils.ts and CouncilData.ts (which has the serializer) are the exact same, but I need a new parseType() function that doesn't depend on Commando (so Utils.ts needs to be altered).

if you need specifically help about converting to sapphire, you are probably better asking off in their support server, it is linked in #useful-servers

Spikers•8mo ago

I joined their server as well, will dive into that if necessary, but I was just wondering if there was a vanilla djs v14 way of doing such (as it was just a helper function)!

souji•8mo ago

discord.js does still not come with a fully fledged framework and command parser/handler there is https://www.npmjs.com/package/create-discord-bot which can help you get v14 set up and the guide https://discordjs.guide/ has sections about a somewhat basic command handler (with slash commands) explaining what's what as discord.js we recommend switching over to slash commands versus content parsing/serializing and as such haven't been and aren't adding any utility to achieve things with prefixed commands so if you do want to stick with command parsing from message content, sapphire is very likely the space to get your answers in the knowledge and support around parsing has decreased here since switching to slash commands, which allow you to do things message commands do not (modals, ephemeral messages only the command author can see) to name two

Spikers•8mo ago

I appreciate it, I'll go there now👍 Will leave this up in case someone from here is able to help, but yes I understand the push for slash commands.
