If I have .ts files that I want transpiled into .js how do I do that using a config file rather than having to specify flags in bun build?

e.g. This command does what I want:

bun build *.ts --outdir=./dist

But if I use this tsconfig.json:

{
  "compilerOptions": {
    "outDir": "./dist",
  },
  "include": ["*.ts"],
}

And run bun build without any flags it doesn’t work.

bun build v1.1.24 (85a32991)
error: Missing entrypoints. What would you like to bundle?

Is there a way to use a config file and not have to use flags every time?
