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.

cli migration native-preview tsc tsgo typescript

tsgo2tsc

Migrate projects from @typescript/native-preview and tsgo to the TypeScript 7 tsc flow.

Supports stable TypeScript, nightly TypeScript, and compatibility mode for tools that still need the TypeScript 6 compiler API.

Usage

bunx tsgo2tsc scan
bunx tsgo2tsc scan ../my-project
bunx tsgo2tsc migrate --dry-run
bunx tsgo2tsc migrate --write --install --test
bunx tsgo2tsc migrate --nightly --write

Development

Run the CLI directly from source (no build step):

bun dev scan
bun dev scan ../other-project
bun dev migrate ../other-project --dry-run
bun dev migrate --cwd ../other-project --write --yes

Watch the production bundle with bun run build:watch.

Commands

| Command | Description | | ---------- | ------------------------------------------------ | | scan | Scan the project and report migration readiness | | migrate | Plan or apply migration from tsgo to tsc | | doctor | Check migration health and verification | | rollback | Restore files from the latest migration snapshot |

Migration modes

stable — typescript@^7.0.0 and tsc
nightly — typescript@next and tsc
compat-stable — @typescript/native aliased to TS7 + typescript aliased to TS6 API
compat-nightly — same as compat but with typescript@next

Compatibility mode is auto-detected when tools like typescript-eslint, typedoc, @microsoft/api-extractor, or direct import "typescript" usage are found.
