You can augment the ContextVariableMap interface to define types for context variables globally across your entire application. This is appropriate when a variable is set by middleware that is applied app-wide and is guaranteed to exist in the context.
For example:
declare module 'hono' {
interface ContextVariableMap {
result: string
}
}You can then utilize this in your middleware:
import { createMiddleware } from 'hono/factory'
// ---cut---
const mw = createMiddleware(async (c, next) => {
c.set('result', 'some values') // result is a string
await next()
})In a handler, the variable is inferred as the proper type:
