Heya @DanielRosenwasser, I've started to run the tarball bundle task on this PR at 902202c. You can monitor the build here.

Hey @DanielRosenwasser, 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/111051/artifacts?artifactName=tgz&fileId=557B32A238563DF17CF4CCE856731C55A0DFE4541192EDA97C42052A30087B1D02&fileName=/typescript-4.5.0-insiders.20210921.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]".;
