Handling CORS Errors when calling Gemini API from the Frontend
Securely proxy your Gemini API generative capabilities through server environments to prevent browser-level CORS blocks.
const response = await ai.models.generateContent({
model: 'gemini-2.5-pro',
contents: prompt,
});
return response.text;
}
```
By offloading the execution to a secure Node environment like Server Actions or standard API routes, we entirely bypass browser CORS limitations while shielding our API keys.
