new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

typebox schema generation for CockroachDB

Drizzle ORM provides integration with typebox to generate typebox schemas from Drizzle ORM schemas. This is supported for CockroachDB dialect only.

typebox schema generation features

The typebox integration supports creating select schemas for tables and enums, and creating insert and update schemas for tables.

typebox schema validation example

This example shows generating and validating schemas for a CockroachDB users table with createInsertSchema, createUpdateSchema, createSelectSchema, and then validating data using Value.Check from typebox: ```ts import { int4, cockroachTable, text, timestamp } from 'drizzle-orm/cockroach-core'; import { createInsertSchema, createSelectSchema, createUpdateSchema } from 'drizzle-orm/typebox'; import { Type } from 'typebox'; import { Value } from 'typebox/value'; const users = cockroachTable('users', { id: int4().primaryKey().generatedAlwaysAsIdentity(), name: text().notNull(), email: text().notNull(), role: text({ enum: ['admin', 'user'] }).notNull(), createdAt: timestamp('created_at').notNull().defaultNow(), }); const insertUserSchema = createInsertSchema(users); const updateUserSchema = createUpdateSchema(users); const selectUserSchema = createSelectSchema(users); const insertUserSchema = createInsertSchema(users, { role: Type.String(), }); const insertUserSchema = createInsertSchema(users, { id: (schema) => Type.Number({ ...schema, minimum: 0 }), role: Type.String(), }); const isUserValid: boolean = Value.Check(insertUserSchema, { name: 'John Doe', email: 'johndoe@test.com', role: 'admin', }); ```
