type hints when all query params are optional are lost #217
Description
What version of Elysia is running?
1.4.10
What platform is your computer?
Darwin 24.3.0 arm64 arm
What steps can reproduce the bug?
import { Elysia, t } from 'elysia'
import { treaty } from './src/treaty2'
const app = new Elysia().get('/optional', ({ query: { name } }) => name, {
query: t.Object({
name: t.Optional(t.String())
})
})
export type App = typeof app
const api = treaty<App>('localhost:8080')
type QueryParams = NonNullable<Parameters<typeof api.optional.get>[0]>['query']
// type QueryParams = Record<string, unknown> | undefinedWhat is the expected behavior?
The type of QueryParams should give some hinting as to the name. Either:
type QueryParams = { name?: string | undefined; } | undefinedor to preserve existing behavior, with additional type hints:
type QueryParams = ({ name?: string | undefined; } & Record<string, unknown>) | undefinedWhat do you see instead?
type QueryParams = Record<string, unknown> | undefinedAdditional information
The same probably follow for headers as well that has the same inference logic as query.
Have you try removing the node_modules and bun.lockb and try again yet?
yes
