Convex

What is Convex?

Convex is an open-source, reactive database designed for modern web and mobile application development. It provides a complete backend solution that simplifies the process of building full-stack applications with real-time updates, robust authentication, and AI-assisted coding.

How does Convex work?

Convex distinguishes itself by offering a fully code-defined backend. Everything from database schemas to queries and APIs is expressed in pure TypeScript. This approach allows developers to keep their backend code closely integrated with their frontend, facilitating type-checking, autocompletion, and AI-driven code generation with high accuracy. Key features include:

• Realtime Updates: Automatically keeps your application synchronized with data changes.
• Authentication: Over 80+ OAuth integrations.
• Components: Independent, modular, TypeScript building blocks for your backend.
• Open Source: Self-host and develop locally.
• AI Coding: Generate high-quality Convex code with AI.

Why is Convex important?

Convex addresses the challenges of modern app development by providing a unified platform that handles data persistence, real-time synchronization, and backend logic. This reduces the complexity of managing multiple services and simplifies the development process. Here's why developers are excited about Convex:

• Simplified Backend Development: Express your entire backend in TypeScript.
• Real-time Data Synchronization: Built-in real-time updates ensure data consistency.
• AI-Assisted Coding: AI tools generate high-quality code, improving productivity.
• Seamless Integrations: Integrates smoothly with popular frameworks like React, Next.js, and more.

How to use Convex?

1. Installation:

   • Start by creating a new Convex project using npm:

   npm create convex
   

2. Code-First Approach:

   • Define your database schema, queries, and mutations in TypeScript.
   • Example:

     import { mutation, query } from "./_generated/server";
     import { v } from "convex/values";
     
     export const setComplete = mutation({
       args: { id: v.id("todos") },
       handler: async (ctx, args) => {
         await ctx.db.patch(args.id, {
           completed: false,
         });
       },
     });
     
     export const list = query({…});
     export const add = mutation({…});
     export const setIncomplete = mutation({…});
     

3. Integrate with Frontend:

   • Use Convex's React hooks to fetch and update data in real-time.
   • Example:

     import { api } from "../../convex/_generated/api";
     import { TodoList } from "./TodoList";
     import { useQuery } from "convex/react";
     
     export function TodoApp() {
       const todos = useQuery(api.todos.list, { count: 5 });
       return <TodoList todos={todos} />;
     }
