Getting Started with ruprizzle: A Schema-First Rust ORM

# Getting Started with ruprizzle: A Schema-First Rust ORM ruprizzle is a schema-first ORM for Rust. You edit a declarative schema.ruprizzle file, run ruprizzle generate, and the tool produces a typed Rust client and migration SQL from the schema diff. The generated client is plain Rust calling sqlx, with no hidden query engine or sidecar binary, and .to_sql() on every builder shows the exact SQL. ## What you get A ruprizzle project gives you a declarative schema, a generated typed client with per-model column tokens, type-safe query building, automatic migration diffing, and Postgres and SQLite support from day one. ## Step 1: Install the CLI Install the ruprizzle CLI with Cargo: cargo install ruprizzle-cli This gives you the ruprizzle command for generating code, running migrations and formatting the schema. ## Step 2: Create a project Run: ruprizzle init --provider postgres This creates a new project with a starter schema.ruprizzle file and a Cargo project already configured to use the generated client. ## Step 3: Add the runtime In your Cargo.toml, or directly during init, add the ruprizzle runtime: cargo add ruprizzle The runtime is the library your application code uses to query the database. ## Step 4: Edit the schema Open schema.ruprizzle and add your first model. For example, a User model with an email and created_at field. The schema is declarative, similar to a Prisma schema. ## Step 5: Generate the client and migration Run: ruprizzle generate This diffs your schema against the last snapshot, writes up.sql and down.sql, and regenerates the typed Rust client. You can inspect the SQL before applying it. ## Step 6: Apply the migration Run: ruprizzle migrate dev --name init This applies the migration to your development database. ## Step 7: Query the database Use the generated client to build type-safe queries. Call .to_sql() on any query builder to see the SQL that will run. The client is plain Rust calling sqlx, so you can drop down to raw SQL or sqlx whenever you need to. ## Status and requirements ruprizzle is in beta at 0.4.0-beta.2. The core is complete and published on crates.io. The minimum supported Rust version is 1.85.
