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 🙏

Srcbook

Srcbook is a TypeScript-centric app development platform. It allows you to create and iterate on web apps incredibly fast using AI as a pair-programmer. It can create or edit web apps, and also write and execute backend code through an interactive notebook interface.

Srcbook is open-source (apache2) and runs locally on your machine. You need to bring your own API key for AI usage (we strongly recommend Anthropic with claude-3-5-sonnet-latest).

Features

App Builder

  • AI app builder for TypeScript
  • Create, edit and run web apps
  • Use AI to generate the boilerplate, modify the code, and fix things
  • Edit the app with a hot-reloading web preview

Notebooks

  • Create, run, and share TypeScript notebooks
  • Export to valid markdown format (.src.md)
  • AI features for exploring and iterating on ideas
  • Diagraming with mermaid for rich annotations
  • Local execution with a web interface

FAQ

See FAQ.

Getting Started

Srcbook runs locally on your machine as a CLI application with a web interface.

Requirements

  • Node.js v18+
  • We recommend using nvm to manage local node versions

Installing

We recommend using npx to always run the latest version from npm

# Using npm
npx srcbook@latest start

# Using your pm equivalent
pnpm dlx srcbook@latest start

You can instead use a global install with <pkg manager> i -g srcbook and then directly call srcbook with srcbook start

Here is the current list of commands:

$ srcbook -h
Usage: srcbook [options] [command]

Srcbook is a interactive programming environment for TypeScript

Options:
  -V, --version                 output the version number
  -h, --help                    display help for command

Commands:
  start [options]               Start the Srcbook server
  import [options] <specifier>  Import a Srcbook
  help [command]                display help for command

Uninstalling

You can remove srcbook by first removing the package, and then cleaning it's local directory on disk:

rm -rf ~/.srcbook

# if you configured a global install
npm uninstall -g srcbook

if you used another pm you will need to use it's specific uninstall command

Analytics and tracking

In order to improve Srcbook, we collect some behavioral analytics. We don't collect any Personal Identifiable Information (PII), our goals are simply to improve the application. The code is open source so you don't have to trust us, you can verify! You can find more information in our privacy policy.

If you want to disable tracking, you can run Srcbook with SRCBOOK_DISABLE_ANALYTICS=true set in the environment.
