Question 1

How to set up Zapatos in a TypeScript project?

Accepted Answer

Install via npm, then run the schema generation command to create types from your PostgreSQL database. Follow the documentation for configuration details, such as setting up database connections and generating initial types.

Question 2

Zapatos vs Prisma: which one should I use for PostgreSQL?

Accepted Answer

Zapatos provides type safety with direct SQL control, ideal if you prefer writing SQL. Prisma offers a higher-level ORM with migrations and a query builder, better for teams wanting more abstraction and built-in features.

Question 3

Does Zapatos handle database migrations?

Accepted Answer

No, Zapatos does not include migration tools. You need to manage schema changes separately using external tools like node-pg-migrate or custom SQL scripts, as it focuses solely on type-safe querying.

Question 4

How does Zapatos generate TypeScript types from PostgreSQL?

Accepted Answer

It introspects your PostgreSQL database schema through queries and generates corresponding TypeScript interfaces, ensuring types match your tables, columns, and relationships accurately.

Question 5

Is Zapatos suitable for large-scale applications?

Accepted Answer

Yes, its type generation scales with complex schemas, but frequent schema updates require manual type regeneration. It's best for teams comfortable with SQL and willing to manage types directly.

Question 6

How to write a join query with Zapatos?

Accepted Answer

Use Zapatos' type-safe query builders to construct joins with SQL-like syntax. The documentation provides examples for writing joins that leverage generated types for compile-time validation.
