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.

tsdown-migrate

A CLI tool to migrate your project from tsup to tsdown.

Usage

npx tsdown-migrate

Options

[...dirs] - Directories to migrate (defaults to current directory)
-d, --dry-run - Preview changes without applying them
-y, --yes - Skip the migration confirmation prompt
--package-manager <name> - Override package manager auto-detection
--no-install - Skip dependency installation

For non-interactive environments, explicitly confirm the migration. Use --no-install when the caller will install dependencies after running other migrations:

npx tsdown-migrate --yes --no-install

When installation is enabled, tsdown-migrate detects the package manager from the project's packageManager field or lockfile. If detection fails in a non-interactive environment, pass --package-manager <name> or --no-install.

What It Does

Renames tsup to tsdown in dependencies and scripts
Transforms tsup config files to tsdown config format
Handles property renames, option transformations, and import path updates
Warns about unsupported options that need manual attention
Runs package manager install after successful migration unless --no-install

Documentation

See the Migration Guide for more details.
