| name | convex-backend |
| description | Build real-time, reactive backend applications with Convex using TypeScript queries, mutations, and actions with automatic reactivity and optimistic updates. Use when building real-time collaborative applications, implementing reactive data synchronization, writing serverless backend functions, creating queries that auto-update, implementing mutations with transactional guarantees, handling file uploads with Convex storage, implementing authentication with Convex Auth, designing reactive database schemas, or building applications requiring instant data synchronization. |

Core Concepts
Queries (Read Data)
```typescript
import { query } from './_generated/server';
import { v } from 'convex/values';
export const list = query({
args: {},
handler: async (ctx) => {
return await ctx.db.query('users').collect();
}
});
export const get = query({
args: { id: v.id('users') },
handler: async (ctx, args) => {
return await ctx.db.get(args.id);
}
});
```
Mutations (Write Data)
```typescript
import { mutation } from './_generated/server';
export const create = mutation({
args: { name: v.string(), email: v.string() },
handler: async (ctx, args) => {
return await ctx.db.insert('users', args);
}
});
```
