Created a function that returns a Valibot type but not getting intellisense for types

[babakfp]

Hi 👋

I created this function:

export const getPluginBaseSchema = (
    options: Parameters<typeof v.object>[0]
) => {
    return v.optional(
        v.merge(
            [
                v.object(options),
                v.object({
                    // ...
                }),
            ],
            v.never()
        ),
        {}
    )
}

And I use it like this:

/** [View on NPM](https://npmjs.com/package/remark-frontmatter). */
remarkFrontmatter: getPluginBaseSchema({
    /** @default true */
    enable: v.optional(v.boolean(), true),
    /** **Important**: Don't change! Only `"yaml"` is supported for now. */
    lang: v.optional(
        v.union([v.literal("yaml")]),
        "yaml"
    ),
    options: v.optional(
        v.special<RemarkFrontmatterCustomOptions>(
            () => true
        )
    ),
}),

/** [View on NPM](https://npmjs.com/package/remark-frontmatter-yaml). */
remarkFrontmatterYaml: getPluginBaseSchema({
    /** @default true */
    enable: v.optional(v.boolean(), true),
    options: v.optional(
        v.special<RemarkFrontmatterYamlCustomOptions>(
            () => true
        )
    ),
}),

The problem is that I'm not getting IntelliSense stuff at all (all is any 😅). My question is how can I fix this? I want to keep the function because this way the code is much cleaner and less boilerplate.

It may work if you use a generic:

export const getPluginBaseSchema = <TEntries extends v.ObjectEntries>(
    options: TEntries
) => {
    return v.optional(
        v.merge(
            [
                v.object(options),
                v.object({
                    // ...
                }),
            ],
            v.never()
        ),
        {}
    )
}

Thanks. Seem like it does the trick. Can I also solve this issue?

Argument of type '{}' is not assignable to parameter of type 'Default<ObjectSchema<{ [TKey in Exclude<keyof TEntries, "plugins">]: TEntries[TKey]; } & { plugins: OptionalSchema<ObjectSchema<{ before: OptionalSchema<SpecialSchema<Preset, Preset>, undefined, Preset | undefined>; after: OptionalSchema<...>; }, NeverSchema, { ...; }>, undefined, { ...; } | undefined>; }, NeverSche...'.ts(2345)

This is because I use the {} is the default value.

It may work if you write {} as const.

Didn't work.
I deleted the custom function and just copied & pasted the merge.
Thanks.

Sorry I could not help you better. I am busy rewriting Valibot to make it even better. If you like, I can take another look at your code in a few weeks.

Thank you. Don't worry about it. All good. No need to revise this in the future, I'm happy with the result. Wish you a successful rewrite 👍🌸.
