Research direction

Start by reproducing the webpack build using the configuration in the issue and inspect src/index.ts, toast.vue.ts, toast.vue, and img/close.png. Compare the TypeScript, Vue loader, and asset-resolution errors with tsconfig.json and package.json. Done means the project compiles normally through webpack without these errors.
