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 🙏

better-sqlite3 Build Status

The fastest and simplest library for SQLite3 in Node.js.

  • Full transaction support
  • Geared for performance, efficiency, and safety
  • Easy-to-use synchronous API (faster than an asynchronous API... yes, you read that correctly)
  • Custom SQL function support
  • 64-bit integer support (invisible until you need it)

How other libraries compare

| |select 1 row  get() |select 100 rows   all()  |select 100 rows iterate() 1-by-1|insert 1 row run()|insert 100 rows in a transaction| |---|---|---|---|---|---| |better-sqlite3|1x|1x|1x|1x|1x| |sqlite and sqlite3|8.4x slower|3.7x slower|28.2x slower|3.6x slower|6.0x slower|

You can verify these results by running the benchmark yourself. Both npm/sqlite and npm/sqlite3 have nearly identical performance because they both use the same engine.

Installation

npm install --save better-sqlite3

If you have trouble installing, check the troubleshooting guide.

Usage

var Database = require('better-sqlite3');
var db = new Database('foobar.db', options);

var row = db.prepare('SELECT * FROM users WHERE id=?').get(userId);
console.log(row.firstName, row.lastName, row.email);

Why should I use this instead of node-sqlite3?

  • node-sqlite3 uses asynchronous APIs for tasks that are either CPU-bound or serialized. That's not only bad design, but it wastes tons of resources. It also causes mutex thrashing which has devastating effects on performance.
  • node-sqlite3 exposes low-level (C language) memory management functions. better-sqlite3 does it the JavaScript way, allowing the garbage collector to worry about memory management.
  • better-sqlite3 is simpler to use, and it provides nice utilities for some operations that are very difficult or impossible in node-sqlite3.
  • better-sqlite3 is much faster than node-sqlite3 in most cases, and just as fast in all other cases.
