Usage

Installation

npm install -D @monstermann/stdlib-transform

pnpm add -D @monstermann/stdlib-transform

yarn add -D @monstermann/stdlib-transform

bun add -D @monstermann/stdlib-transform

nub add -D @monstermann/stdlib-transform

aube add -D @monstermann/stdlib-transform

Setup

Vite, Rolldown, tsdown

import { stdlib } from "@monstermann/stdlib-transform"
import { defineConfig } from "vite"

export default defineConfig({
    plugins: [stdlib()],
})

import { stdlib } from "@monstermann/stdlib-transform"
import { defineConfig } from "rolldown"

export default defineConfig({
    input: "src/index.ts",
    plugins: [stdlib()],
})

import { stdlib } from "@monstermann/stdlib-transform"
import { defineConfig } from "tsdown"

export default defineConfig({
    entry: "src/index.ts",
    plugins: [stdlib()],
})

Bun

For Bun.build:

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

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

For bun run and bun test, register it in a preload:

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

plugin(stdlibBun())

preload = ["./preload.ts"]

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

Bun only uses the first plugin that returns something for a file. With other plugins, call transform(code, path) from your own instead.

Options

Option	Default	Description
`include`	`/\.m?[jt]sx?(?:\?.*)?$/`	Only files whose path matches one of these are transformed.
`exclude`		Files whose path matches one of these are skipped.
`debug`	`false`	`true`, or a RegExp of paths: prints what is being replaced.
`enforce`		`"pre"` or `"post"`, not for Bun.

Dependencies in node_modules are never transformed.
