Core Concepts
Queries (Read Data)
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)
export const create = mutation({args: {name: v.string(), email: v.string()}, handler: async (ctx, args) => {return await ctx.db.insert('users', args);}}); ```
