Core utilities and helpers for Protocol projects.

Installation

Install the package using your preferred package manager:

bun add @protoxyz/orm-core
# or
pnpm add @protoxyz/orm-core
# or
npm install @protoxyz/orm-core

Usage

This package provides various utility functions and types for use in Protocol projects. Here are some examples:

Minimal Table Setup

import { createEnhancedTable } from '@protoxyz/orm-core';
import { pgTable, text, timestamp, varchar } from 'drizzle-orm/pg-core';
import { drizzle } from 'drizzle-orm/node-postgres';
import { Pool } from 'pg';

// Define your table
const posts = pgTable('posts', {
  id: varchar('id').primaryKey(),
  title: text('title').notNull(),
  content: text('content').notNull(),
  createdAt: timestamp('created_at').notNull().defaultNow(),
  updatedAt: timestamp('updated_at').notNull().defaultNow(),
});

// Create a database connection
const pool = new Pool({
  connectionString: process.env.DATABASE_URL,
});
const db = drizzle(pool);

// Create an enhanced table
const enhancedPosts = createEnhancedTable({
  table: posts,
  createdAtColumn: posts.createdAt,
  updatedAtColumn: posts.updatedAt,
});

// Usage example
async function getPosts() {
  const result = await enhancedPosts.paginateWithCursor(db, {
    limit: 10,
    sort: { column: 'createdAt', order: 'desc' },
  });

  console.log(result.items);
  console.log(result.meta);
}

getPosts();

Kitchen Sink Example

import { createEnhancedTable, createPaginateParamsCache, parseAsDateRange, parseAsClampedInteger } from '@protoxyz/orm-core';
import { pgTable, text, timestamp, varchar, pgEnum } from 'drizzle-orm/pg-core';
import { drizzle } from 'drizzle-orm/node-postgres';
import { Pool } from 'pg';
import { eq } from 'drizzle-orm';

// Define an enum for post status
const postStatusEnum = pgEnum('post_status', ['draft', 'published', 'archived']);

// Define a more complex table
const posts = pgTable('posts', {
  id: varchar('id').primaryKey(),
  title: text('title').notNull(),
  content: text('content').notNull(),
  slug: text('slug').notNull().unique(),
  status: postStatusEnum('status').notNull().default('draft'),
  createdAt: timestamp('created_at').notNull().defaultNow(),
  updatedAt: timestamp('updated_at').notNull().defaultNow(),
  deletedAt: timestamp('deleted_at'),
});

// Create a database connection
const pool = new Pool({
  connectionString: process.env.DATABASE_URL,
});
const db = drizzle(pool);

// Create an enhanced table with more options
const enhancedPosts = createEnhancedTable({
  table: posts,
  slugColumn: posts.slug,
  createdAtColumn: posts.createdAt,
  updatedAtColumn: posts.updatedAt,
  deletedAtColumn: posts.deletedAt,
  searchColumns: [posts.title, posts.content],
  defaultSort: { column: 'createdAt', order: 'desc' },
  logger: console.log,
});

// Create a pagination params cache
const paginationCache = createPaginateParamsCache({
  status: postStatusEnum,
  createdAt: parseAsDateRange,
  limit: parseAsClampedInteger(1, 100),
});

// Usage examples
async function createPost(title: string, content: string, status: 'draft' | 'published' | 'archived' = 'draft') {
  const result = await enhancedPosts.create(db, { title, content, status });
  console.log('Created post:', result);
}

async function getPosts(searchParams: URLSearchParams) {
  const { cursor, limit, search, status, createdAt, sort } = paginationCache.parse(searchParams);

  const result = await enhancedPosts.paginateWithCursor(db, {
    cursor,
    limit,
    search,
    filters: {
      status: status || undefined,
      createdAt: createdAt || undefined,
    },
    sort,
  });

  console.log('Posts:', result.items);
  console.log('Pagination meta:', result.meta);
}

async function updatePost(id: string, data: Partial<typeof posts.$inferInsert>) {
  const result = await enhancedPosts.update(db, id, data);
  console.log('Updated post:', result);
}

async function deletePost(id: string) {
  const result = await enhancedPosts.delete(db, id);
  console.log('Deleted post:', result);
}

// Example usage
async function main() {
  await createPost('Hello, World!', 'This is my first post.', 'published');

  const searchParams = new URLSearchParams({
    limit: '20',
    status: 'published',
    createdAt: JSON.stringify({ from: '2023-01-01', to: '2023-12-31' }),
    search: 'Hello',
    sort: 'createdAt:desc',
  });

  await getPosts(searchParams);

  await updatePost('some-id', { title: 'Updated Title' });

  await deletePost('some-id');
}

main().catch(console.error);

Working with Cursors

import { encodeCursor, decodeCursor } from '@protoxyz/orm-core';

const cursor = 'some-data';
const encoded = encodeCursor(cursor);
console.log(encoded); // Outputs base64url encoded string

const decoded = decodeCursor(encoded);
console.log(decoded); // Outputs 'some-data'

API Documentation

Enhanced Table

• createEnhancedTable<T extends PgTableWithColumns<any>>(options: EnhancedTableOptions<T>): Creates an enhanced table with additional functionality for pagination, filtering, and sorting.

Helpers

• generateUniqueString(length: number): string: Generates a random string of specified length.
• encodeCursor(cursor: string): string: Encodes a cursor string to base64url format.
• decodeCursor(encodedCursor: string): string: Decodes a base64url encoded cursor.
• findColumn(table: Table, dbColumnName: string): keyof typeof table: Finds a column in a Drizzle ORM table by its database column name.
• slugify(nameOrSlug: string): string: Converts a string into a URL-friendly slug.

Params

• parseAsSortAndOrder: Parser for sorting and ordering parameters.
• parseAsDateRange: Parser for date range parameters.
• parseAsClampedInteger(min: number, max: number): ParserBuilder<number>: Creates a parser for integer values within a specified range.
• createPaginateParamsCache<Parsers extends PaginateParamParsers>(parsers: Omit<Parsers, "page" | "limit" | "sort" | "search">): Creates a cache for pagination parameters.

Types
