How to use alias with vitest workspace

[andrew-vdb]

Clear and concise description of the problem

No documentation.

intellisense is working in my spec file no import error but vitest extension for some reason can not load module with alias

Suggested solution

When using workspace, put the resolve in the "vitest.workspace.ts" !

import { defineWorkspace } from 'vitest/config'
import { resolve } from 'path';
export default defineWorkspace(
    [
        {
            test: {
                include: ['./packageName/**/*.spec.{ts,js}'],
                name: 'packageName',
                alias: {
                    '@': resolve(__dirname, './'),
                }
            }
        }
    ])

You could try something like:

import { defineWorkspace } from 'vitest/config'
import { resolve } from 'path';
export default defineWorkspace(
    [
        {
            test: {
                include: ['./packageName/**/*.spec.{ts,js}'],
                name: 'packageName',
                alias: {
-                    '@': resolve(__dirname, './'),
+                    '@': resolve(__dirname, './packageName'),
                }
            }
        }
    ])

But without seeing rest of your project's code it's impossible to help any further.

Here's also one example that uses alias with workspaces: https://stackblitz.com/~/edit/vitest-sonar-reporter-workspaces?file=packages/server/vitest.config.ts.

The proposed solution is already working, sorry that i may not be clear enough. The issue is when i googled and reading the doc, no one mention to put alias in defineWorkspace

[AriPerkkio]

Doesn't https://vitest.dev/guide/workspace already cover configuring workspaces? What kind of change would you propose there? It shouldn't be alias specific as we simply cannot cover all possible configuration options there.

[andrew-vdb]

it can be faq or troubleshoot

when following conditions are true

• using alias
• typescript intellisense is working
• using vitest workspace
• vitest extensions in vs code give error of failed to import

Please add alias in vitest.workspace.ts

worse case they can also find this issue
