Absolute path not working in Vite project React TS

I'm struggling to get absolute path to work in a Vite react-ts project.

Here's how I created the project

npm init @vitejs/app
npx: installed 6 in 1.883s
√ Project name: ... test-vite
√ Select a framework: » react
√ Select a variant: » react-ts

Then I added baseUrl to tsconfig.json based on the TS official doc:

{
  "compilerOptions": {
    "baseUrl": "./src",
    ...

followed by adding a simple component (T:\test-vite\src\components\Test.tsx)

import React from "react";

const Test = () => <h1>This is a Test.</h1>;

export default Test;

Finally I import the Test component in App.tsx
but it won't let me use absolute path:

import Test from "components/Test";

I get this error

whereas if I use relative path, the app works in dev & build mode without any error:

import Test from "./components/Test";

How can I make absolute path work in the project?

There are two problems here:

• Tell typescript how to resolve import path
• Tell vite how to build import path

You only tell typescript how to resolve, but vite don't know how to build. So refer to the official document resolve.alias, maybe this is what you want:

// vite.config.ts
{
  resolve: {
    alias: [
      { find: '@', replacement: path.resolve(__dirname, 'src') },
    ],
  },
  // ...
}

You can import path like this (or any module under ./src):

import Test from "@/components/Test";
import bar from "@/foo/bar"

Moreover, you can use vite plugin vite-tsconfig-paths directly, it makes you don't have to manually configure resolve.alias

Follow the instructions below:

1. Install vite-tsconfig-paths as dev dependency

2. Inject vite-tsconfig-paths using the vite.config.ts module

import { defineConfig } from 'vite'
import tsconfigPaths from 'vite-tsconfig-paths'

export default defineConfig({
  plugins: [tsconfigPaths()],
})
