Convex
// convex/tasks.ts (server function)
import { query, mutation } from './_generated/server';
export const list = query(async (ctx) => ctx.db.query('tasks').collect());
export const create = mutation(async (ctx, { text }) => {
await ctx.db.insert('tasks', { text, isCompleted: false });
});
// React component
import { useQuery, useMutation } from 'convex/react';
const tasks = useQuery(api.tasks.list);PlanetScale
import { connect } from '@planetscale/database';
const conn = connect({
host: process.env.DATABASE_HOST,
username: process.env.DATABASE_USERNAME,
password: process.env.DATABASE_PASSWORD,
});
const results = await conn.execute('SELECT * FROM users LIMIT 10');
console.log(results.rows);Community Verdict
