Cannot access '' before initialization

[colinblaise]

I've spent several hours now reviewing existing issues around the error Cannot access 'ActionTable before initialization, but none of the existing issues appear to have the same error that I receive.

In several of my components, when I save a change, I receive an error similar to above. It's always referencing a component import.

It appears that the ActionTable component is being loaded *after the ComputerDetailsPage component, which may be causing the Cannot access 'ActionTable before initialization since ActionTable is loaded after and not before?

I've tried detecting circular dependencies, but I cannot find any.

Anyone else experiencing a similar issue?

Posting under discussions because I cannot create a reproduction repo yet

Update:

I am using vue-router v3.5.4, and I believe my issues are stemming from my (perhaps incorrect) use of vue-router.

I have a router.js file where I export a router instance

// router.js
const router = makeRouter(store);

export default router;

I have helper functions that utilize the router

// helpers.js
import router from "@/router";

export function helperFunction() { // do something with router };

All components that import helperFunction are showing the error I initially posted. However, when I remove the dependency on router.js from helpers.js, the error goes away.

I'm almost certain I am incorrectly using the router here, but I haven't noticed any issues with this approach until using vite. Thoughts?

I'm facing the same issue.

It occurs when using vue router.

This is my app.js:

import router from './plugins/router';
...

const app = createApp(AppRoot);

app.use(router); // <--- Here is the problem :(

With that configuration, it throws:

Uncaught ReferenceError: Cannot access 'router' before initialization

In my router.js I have a basic config:

import { createRouter, createWebHistory } from 'vue-router';
import routes from '../routes/routes';

export default createRouter({
  history: createWebHistory(),
  routes,
});

I am facing the same issue. How did you end up solving the problem?

Do you have Circular Dependency on ActionTable class?

I'm having the same issue，I referenced the router in the ts file
index.ts:29 Uncaught ReferenceError: Cannot access 'BlankLayout' before initialization

I'm having this issue too and if router is relevant then I'm using the TanStack Router. I took care of circular dependencies but that didn't solve the issue.

Same. Circular dependencies isn't the case.

Same here! Quite confusing...
I'm using Vite 5.4.8, React 18.3.1, React Router 6.26.2

Hi everyone,

I want to confirm that this error is 100% due to a circular dependency. I have already resolved it in my production application. Let me explain. This circular dependency is related to the "file" scope, not the function scope. In my case:

• I have a file named app.config.ts where I store all the app constants (configuration), e.g., export const appName: string.

Everything works fine until I introduce a folder named "routes" containing some files that export routeInfo: { routeId: string, routePath: string }.

To centralize all routeInfo, I export a constant named appRouteMeta: RouteInfo[] in app.config.ts, which is a collection of all routeInfo from all my routes.

Now, in some route.ts files that have routeInfo, I import app.config.ts to use the constant appName. This is where the issue arises. The solution is to move routeInfo to a separate file named app.routes.ts.

So, please remember, this issue is about file scope, not function scope.

I hope my experience can help others.
