Prisma & Drizzle

Type-safe query builders for TypeScript. Instead of writing raw SQL strings, you call typed methods — your editor autocompletes columns and the compiler catches mistakes before they hit the database.

Demo 01

Build a query with your mouseSimulation

Pick a model, choose fields, add a filter — and watch a real-looking Prisma or Drizzle query assemble itself, then return typed results from a seeded dataset. This is exactly the shape of code these tools generate.


      
Return type inferred automatically

Autocomplete is the superpowerConcept

Because the schema is described in TypeScript, your editor knows every column and its type. Type a dot and it suggests valid fields — misspell one and it won't compile. No more guessing column names from memory.

user.

Switching user for order in Demo 1 changes the available fields — the builder only ever offers columns that actually exist, just like real autocomplete.

Prisma vs Drizzle — two philosophies

Both give you type safety; they differ in style. Prisma uses its own schema file and a generated client (higher-level, batteries-included). Drizzle stays close to SQL with a thin, SQL-like builder (lighter, more explicit).

Prisma

  • • Own schema.prisma file
  • • Generated client + migrations
  • • Reads like an object graph
  • • Great DX, slightly heavier

Drizzle

  • • Schema is plain TypeScript
  • • SQL-like, minimal abstraction
  • • Tiny, fast, edge-friendly
  • • You stay close to the SQL

What "type-safe" actually saves you

A raw SQL string is opaque to the compiler — a typo in a column name only fails at runtime, in production. A typed query builder turns that into a red squiggle in your editor, today.

// ❌ Raw string — typo found only when it runs
db.query("SELECT nmae FROM users")   // 💥 at runtime

// ✓ Typed — compiler stops you immediately
db.select({ name: users.nmae })           // 🔴 Property 'nmae' does not exist

The query builder is an interactive JavaScript simulation. Real Prisma and Drizzle are TypeScript libraries that run in Node.js against a real database and rely on the TypeScript compiler for their type safety — none of which exists in a browser tab. So this page assembles the query strings and returns rows from a seeded in-page dataset to faithfully mimic the real experience; the "typed results" and autocomplete menu are illustrations of what your editor and the compiler give you, not a live type-checker. The shared CSS shell provides the page styling.
