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); } }); ```
