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/161484/artifacts?artifactName=tgz&fileId=1C3B7BFF6CBB4A613EC6AEE9B252E7058A04A68B8FB501680F0ED376A6E7014B02&fileName=/typescript-5.5.0-insiders.20240426.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/pr-build@5.5.0-pr-58333-2".;

Readability nit, but I have a real hard time trying to read this one; is there another way to put this?

let files = filter(getSourceFilesToEmit(host, file), isSourceFileNotJson);
if (file) {
   files = contains(files, file) ? [file] : emptyArray;
}

Maybe? If not, no worries, I just have problems reading ternaries.

Sorry its hard to read for you. I prefer consts over let for this. Do you think having it multi line will be more readable

[jakebailey]

It's fine as it is, no worries.
