MESSAGE_MATCHER_IS_ALREADY_BUILT

Kind: Constant

Source: src/router.ts

Error message indicating that a route cannot be added because the matcher is already built.

MESSAGE_MATCHER_IS_ALREADY_BUILT stores the error message used when code attempts to add a route after its matcher has been built. It keeps this validation message consistent within src/router.ts when route configuration occurs in the wrong order.

Definition

ts
'Can not add a route since the matcher is already built.'

Value

ts
'Can not add a route since the matcher is already built.'

Usage

ts
import { MESSAGE_MATCHER_IS_ALREADY_BUILT } from "./router";

function addRoute(matcherBuilt: boolean) {
  if (matcherBuilt) {
    throw new Error(MESSAGE_MATCHER_IS_ALREADY_BUILT);
  }

  // Register the route before building the matcher.
}

AI Coding Instructions

Use MESSAGE_MATCHER_IS_ALREADY_BUILT instead of duplicating the matcher-built error text.
Check matcher build state before registering a new route.
Add routes before the router builds its matcher.
Keep errors related to route registration in src/router.ts aligned with this constant.
