type WorkflowCtx<TExtensions> = Ctx<any, any, TExtensions>;Defined in: packages/workflow-core/src/types.ts:380
Helper alias for typing functions that only care about middleware extensions — not the calling workflow's specific input / state shape. Common in shared utility helpers:
async function chargeUser( ctx: WorkflowCtx<{ user: User }>, amount: number, ) { return ctx.step('charge', () => stripe.charge(amount, ctx.user.id)) }
For helpers that need typed ctx.input or ctx.state, use the full Ctx<TInput, TState, TExt> directly.
