Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Cloud Database Client for VectorX

Readme

@vectorx/cloud-database-client(平台内部)

用于在平台侧(如 Web-IDE / 服务端)以统一 API 方式访问不同数据库(当前先支持 Postgres)。

设计分层

  • Provider(抽象能力):按 dbType 实现 schema 读取、SQL 执行、DDL/结构修改等能力(当前先落地 PG)。
  • DatabaseClient(对外入口):封装 provider,实现 executeSql / getTableColumns / listTables / close 等统一操作。

注意:本包定位为平台内部使用,与面向开发者的 @vectorx/database-sdk(Supabase/Data API)职责不同。

快速使用(PG)

import { createDatabaseClient, OrmLikeDbLogger, PostgresProvider } from "@vectorx/cloud-database-client";

// 由平台侧负责获取连接配置(可来自网关/配置中心/密钥系统等)
const provider = new PostgresProvider({
  config: {
    host: "localhost",
    user: "database-user",
    database: "mydb",
    max: 20,
    idleTimeoutMillis: 30000,
    connectionTimeoutMillis: 2000,
  },
  verbose: true,
  logger: new OrmLikeDbLogger({ format: "pretty" }),
  maxValueLength: 200,
});

const client = createDatabaseClient({ provider });

// 1) 执行 SQL(PG 默认池化)
const { rows } = await client.executeSql({
  sql: "select now() as now",
  readonly: true,
});

// 2) 读取字段
const columns = await client.getTableColumns({ schema: "public", table: "users" });

await client.close();
