Zero dependencies Query Builder for Cloudflare Workers

This module provides a simple standardized interface while keeping the benefits and speed of using raw queries over a traditional ORM.

workers-qb is not intended to provide ORM-like functionality, rather to make it easier to interact with the database from code for direct SQL access using convenient wrapper methods.

Currently, 2 databases are supported:

Features

Installation

npm install workers-qb --save

Example for Cloudflare Workers D1

import { D1QB } from 'workers-qb'

export interface Env {
  DB: any
}

export default {
  async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise<Response> {
    const qb = new D1QB(env.DB)

    const fetched = await qb
      .fetchOne({
        tableName: 'employees',
        fields: 'count(*) as count',
        where: {
          conditions: 'active = ?1',
          params: [true],
        },
      })
      .execute()

    return Response.json({
      activeEmployees: fetched.results?.count || 0,
    })
  },
}

Example for Cloudflare Workers with PostgreSQL

Remember to close the connection using ctx.waitUntil(qb.close()); or await qb.close(); at the end of your request. You may also reuse this connection to execute multiple queries, or share it between multiple requests if you are using a connection pool in front of your PostgreSQL.

You must also enable node_compat = true in your wrangler.toml

You need to install node-postgres:

npm install pg --save
import { PGQB } from 'workers-qb'
import { Client } from 'pg'

export interface Env {
  DB_URL: string
}

export default {
  async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise<Response> {
    const qb = new PGQB(new Client(env.DB_URL))
    await qb.connect()

    const fetched = await qb
      .fetchOne({
        tableName: 'employees',
        fields: 'count(*) as count',
        where: {
          conditions: 'active = ?1',
          params: [true],
        },
      })
      .execute()

    ctx.waitUntil(qb.close())
    return Response.json({
      activeEmployees: fetched.results?.count || 0,
    })
  },
}
