Infer typescript type from Schema

[Antoine-Regembal]

Hi, thanks for the awesome package,

I could not find a way to infer a typescript type from a schema, that I could use elsewhere in my app to help build the correct object to insert in my repository.

For example considering this schema:

export const messageSchema = new Schema("message", {
    name: { type: "text" },
    category: { type: "string" },
    lastUpdated: { type: "date" },
    lastUpdater: { type: "string" },
});

I could totally write the typescript type myself and export it like:

export type MessageSchema = {
    name: string,
    category: string,
    lastUpdated: date,
    lastUpdater: string,
};

But if I update the schema I have to update the type.

Could we find a way to infer the typescript type from a Schema so its always sync with something like:

export const messageSchema = new Schema("message", {
    name: { type: "text" },
    category: { type: "string" },
    lastUpdated: { type: "date" },
    lastUpdater: { type: "string" },
});

export type MessageSchema = Schema.infer<typeof messageSchema> // {name: string; category: string; lastUpdated: string; lastUpdater: string}

This is inspired from the Zod type inference https://zod.dev/?id=type-inference

Thanks :)

Right now this is not built into redis-om.
You can however build your own type to do that mapping which is rather simple but would require wrapping the schema call.

Alternatively if you are interested you can take a look at #188
