Hey @jakebailey, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/164551/artifacts?artifactName=tgz&fileId=A1C0C719604D3B99B71BF02D9310ED868E53723F4E9CD8C7A078388A6E31827E02&fileName=/typescript-5.8.0-insiders.20250117.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/[email protected]".;
