### ✅ 1. **Check Firestore Data Structure**
In Firestore, verify that the `image` field **actually exists** in each document under the `portfolio` collection.
– Go to [Firebase Console](https://console.firebase.google.com/)
– Navigate to **Firestore Database**
– Open your `portfolio` collection
– Confirm that each document contains the field `image` with a valid URL
—
### ✅ 2. **Ensure Firestore Rules Allow Reads**
Your Firestore security rules should allow reads on the `portfolio` collection for the current user or environment:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /portfolio/{document=**} {
allow read, write: if true; // or add proper auth checks
}
}
}
—
### ✅ 3. **Ensure the Correct Export Format**
In your `fetchPortfolioItems`, make sure `doc.data()` returns the correct object.
You're doing this:
return snapshot.docs.map(doc => ({
id: doc.id,
...doc.data(),
}))
Which is correct.
To debug, log each item:
const items = snapshot.docs.map(doc => ({
id: doc.id,
...doc.data(),
}));
console.log('Fetched items:', items);
return items;
Check the console to see if `image` is present.
—
### ✅ 4. **Check Firestore Timestamp Conversion**
Sometimes `createdAt` as a `Date` object causes serialization issues. You can use `Timestamp`:
import { Timestamp } from 'firebase/firestore'
await addDoc(portfolioCollection, {
title,
description,
url,
image: imageUrl,
imagePath: imgPath,
createdAt: Timestamp.now(),
})
—
### ✅ 5. **Accessing in UI (Frontend)**
If you're rendering the image in Vue or React, make sure the property is being accessed correctly:
<img :src="item.image" alt="Portfolio image" />
—
### ✅ 6. **Check Firebase Storage Rules**
Also, confirm that your storage rules allow downloading images:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /portfolio/{allPaths=**} {
allow read, write: if true; // replace with proper auth logic
}
}
}
—
If all the above checks out and you're still not getting the image, let me know what your console output is when logging the fetched data — I can help debug further from there.
—
### 🔍 Let's walk through a quick checklist:
#### ✅ 1. **Log the fetched data**
In your component or wherever you're calling `fetchPortfolioItems`, log the response:
const items = await fetchPortfolioItems();
console.log('Fetched portfolio items:', items);
> Check if `image` appears in the log for each item.
—
#### ✅ 2. **Inspect a single item**
Double-check by logging just one item:
console.log('First item:', items[0]);
If the image URL is there in the log but not appearing in the UI, it's likely a rendering issue.
—
#### ✅ 3. **Check how you're rendering the image in the UI**
For Vue:
<img :src="item.image" alt="Portfolio Image" />
For React:
<img src={item.image} alt="Portfolio Image" />
> Also inspect the element in dev tools — make sure the `src` is correctly applied, and not broken or 403/404.
—
#### ✅ 4. **Broken image URLs?**
Visit the image URL manually in a browser. If it gives a `403` or `not found`, it could be a Firebase Storage permissions issue.
Update storage rules (temporarily for testing):
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /portfolio/{allPaths=**} {
allow read: if true;
allow write: if request.auth != null;
}
}
}
—
#### ✅ 5. **Recheck `addDoc` image field**
From your code, it looks correct:
const docRef = await addDoc(portfolioCollection, {
title,
description,
url,
image: imageUrl, // 👈 this should work
imagePath: imgPath,
createdAt: new Date(),
});
You might want to **re-add** an item and confirm that the new image also doesn't show.
—
If all of this checks out and it’s *still* not rendering — could you share how you're rendering the portfolio items in your frontend (Vue, React, etc.)? That might help pinpoint it.
Type '{ id: string; }' is not assignable to type 'never'
const portfolioItems = ref([])
const loadItems = async () => {
portfolioItems.value = await fetchPortfolioItems();
console.log(portfolioItems.value);
}
—
### ✅ Solution: Give your `ref` a proper type
You can fix it by explicitly typing the items:
#### Option 1: Inline type
const portfolioItems = ref<{ id: string; title: string; description: string; url: string; image: string; imagePath: string; createdAt: any }[]>([])
If you already know the structure, this works fine.
—
#### Option 2: Define a reusable type or interface
interface PortfolioItem {
id: string;
title: string;
description: string;
url: string;
image: string;
imagePath: string;
createdAt: any;
}
const portfolioItems = ref<PortfolioItem[]>([])
This is cleaner and more scalable.
—
#### Option 3: If you're okay with loose typing for now
const portfolioItems = ref<any[]>([])
> Not recommended long-term, but useful during debugging or prototyping.
—
Once you do that, your `loadItems()` function will work perfectly:
const loadItems = async () => {
portfolioItems.value = await fetchPortfolioItems();
console.log(portfolioItems.value);
}
Let me know if you want to make `createdAt` a `Date` or a Firebase `Timestamp` – I can help format it too.
