Leveraging Snowflake as a Data Type within Mongoose Schema

Context: Discord.js utilizes Snowflakes to distinguish between various items such as messages, members, and guilds. In my current situation, I am employing snowflakes as distinct identifiers for members within the guild, serving as the primary key in my MongoDB database.

Challenge: My goal is to integrate Discord's Snowflake as a data type within my Mongoose schema:

import { Snowflake } from 'discord.js';
import { Schema } from 'mongoose';

const MembershipSchema: Schema = new Schema({
    discordID: { type: Snowflake, required: true, unique: true },
});

However, I encounter an issue with VSCode's Intellisense indicating that 

'Snowflake' is only recognized as a type, not a value in this context.
This discrepancy perplexes me because my understanding based on Discord.js documentation was that Snowflake functions as a type (essentially representing a string).

While resorting to using string instead is a viable solution, I am curious if there exists a method to implement it similarly to the format displayed above. I aim to explicitly specify that the input for the discordID field must adhere to the Snowflake criteria, rather than accepting any generic string.

Answer №1

I have discovered a more suitable approach to enforcing the types, drawing inspiration from suggestions by @MrMythical and @Toasty. While their input was helpful, it fell short of providing a complete solution for my requirements.

After dedicating additional time to research, I found that simply incorporating a typing interface into the model creation process proved to be effective. In tools like VSCode, Intellisense can then acknowledge this addition and enforce the specified types on the schema parameters based on the interface definitions.

An illustrative example is presented below:

MembershipModel.ts

import { model, Schema } from 'mongoose';
import Membership from '../interfaces/MembershipStorage';

const MembershipSchema: Schema = new Schema(
    {
        discordID: { type: String, required: true, unique: true },
        ieeeID: { type: String, required: true, unique: true },
    },
    {
        collection: 'members',
        minimize: false,
        strictQuery: true,
    }
);

export default model<Membership>('Member', MembershipSchema);

MembershipStorage.ts

import { Snowflake } from 'discord.js';

export default interface Membership {
    discordID: Snowflake;
    ieeeID: string;
}
