> refactor the auth middleware to handle token refresh
I'll refactor the auth middleware. Here's my plan:
1. Extract token validation into a helper
2. Add automatic refresh when token expires within 5min
3. Update error handling for refresh failures
src/middleware/auth.ts
- import { verify } from 'jsonwebtoken';
+ import { verify, decode } from 'jsonwebtoken';
+ import { refreshToken } from '../lib/auth';
src/lib/auth.ts (new file)
+ export async function refreshToken(token: string) {
+ const decoded = decode(token);
+ // ... refresh logic

Extracted the refresh logic into a helper
and added retry with backoff.

Common questions about Cosyra
Direct answers for the questions developers ask before they trust a mobile terminal with real work.
Can I run Claude Code on my iPhone?
Yes. You get an isolated Ubuntu container with Claude Code, Codex CLI, OpenCode, and Gemini CLI pre-installed. Same experience as your laptop.
Which AI CLI tools does Cosyra support?
Claude Code, Codex CLI, OpenCode, and Gemini CLI come pre-installed. The container includes Node.js, Python, Git, tmux, vim, and standard dev tools. You can install additional packages as needed.
Do I need to use my own API keys?
Yes. Cosyra follows a bring-your-own-key model so developers can use their own provider accounts and keep control over usage and billing.
Does Cosyra work on Android and iPhone?
Yes. Cosyra runs on both iOS and Android with the same terminal experience across devices.
Can I use Cosyra for private or proprietary code?
Yes. Each user gets their own isolated cloud container. Your code and files are private to your environment.
Why use Cosyra instead of SSHing into my own server?
No infrastructure to manage, no ports to configure, no mobile UX to fight. Cosyra is a ready-to-use dev environment on your phone.
How does pricing work?
Cosyra comes with a free trial that includes 10 hours or 7 days of full access. After that, Pro is $29.99/month or $300/year and includes 120 hours/month, 30 GB persistent storage, and session hibernation. Subscriptions are available via in-app purchase.
How does Cosyra handle API keys?
Bring your own API key. Keys are stored securely on your device using platform-native encryption. When you run an AI agent, your key is transmitted to your cloud container over an encrypted connection.
Do Cosyra sessions persist between app opens?
Yes. Your files persist between sessions. Pro users get session hibernation: your container pauses after 10 minutes of inactivity and resumes where you left off.
