@monstermann/stdlib-transform

The build plugin of @monstermann/stdlib. It replaces what you use of globals with direct imports, compiles match into conditionals, and pipe into the calls it makes.

bun add -D @monstermann/stdlib-transform

Vite, Rolldown, tsdown

import { stdlib } from "@monstermann/stdlib-transform";

export default defineConfig({
    plugins: [stdlib({ enforce: "pre" })],
});

| Option | Default | Description | | --------- | ----------------------- | ---------------------------------------------------------------------- | | include | .js, .ts, .jsx, … | RegExp(s), only files whose path matches are transformed. | | exclude | | RegExp(s), files whose path matches are skipped. | | enforce | | "pre" or "post". | | debug | false | true or a RegExp matching file paths, prints what is being replaced. |

Dependencies are always skipped: what a dependency uses of Array or Object is its own.

Bun

import { stdlibBun } from "@monstermann/stdlib-transform";

await Bun.build({
    entrypoints: ["./src/index.ts"],
    plugins: [stdlibBun()],
});

A preload makes bun test and bun run go through the plugin as well:

import { plugin } from "bun";
import { stdlibBun } from "@monstermann/stdlib-transform";

plugin(stdlibBun());

preload = ["./preload.ts"]

[test]
preload = ["./preload.ts"]

Bun only uses the first plugin that loads a file. When there are others, call transform(code, path) from your own.
