Can't build vue 3 project if importing aws-amplify package

[ivanovvitaly]

Describe the bug
I installed aws-amplify npm package to the clean vue 3 project and added Amplify import. When I run npm run build I get long list of errors, npm run serve runs without errors though. If I remove aws-amplify import statement the project compiles without errors.
Please advice

To Reproduce
Steps to reproduce the behavior:

1. Setup new vue 3 project with webpack, typescript
2. Install aws-amplify package
3. Add Amplify import in main.ts import { Amplify } from 'aws-amplify';
4. Build project with npm run build
5. See errors error.txt

Expected behavior
Project should compile without errors

Desktop (please complete the following information):

• OS: Windows 11 Enterprise 22H2 Build 22621.4460
• Browser -
• Version -
• Node v22.9.0

Additional context

const app = createApp(App)
app.mount('#app')

Hey, thanks for raising this! I'm going to transfer this over to our JS repository for better assistance 🙂

Hi @ivanovvitaly thank you for opening this issue.

I did a quick test with creating a new Vue starter app, and I couldn't reproduce this issue. I've taken the following steps:

1. npm create vue@latest
2. npm install aws-amplify
3. modified main.ts using the code example you provided
4. npm run build succeeded with the following output

❯ npm run build                   

> test-build@0.0.0 build
> run-p type-check "build-only {@}" --


> test-build@0.0.0 type-check
> vue-tsc --build --force


> test-build@0.0.0 build-only
> vite build

In noticed that you are using @vue/cli-service which is already in the maintenance mode, and your typescript version is quite low (may have compatibility issue with @types/node (not particular the aws-amplify packages)). Could you try to upgrade your Vue tooling and try again?

Hey @HuiSF, thanks for quick feedback! I tried clean vue 3 with vite template it builds without issues.
The initial project was setup with vue 3 with webpack .
Can I make it work with webpack?

@ae-vivanov, that's great to hear that it's now building without issues using Vite. We don't think webpack is the issue here, but rather Typescript. Did you also upgrade the version of typescript as well before trying the webpack build again?

[ivanovvitaly]

@cwomack upgraded to typescript 5.6.3, compiled without errors. Thank you so much!

@ivanovvitaly, glad to hear that and thanks for following up and closing the issue!
