bun-tsconfig-paths

A Bun plugin that resolves TypeScript path aliases from your tsconfig.json.

Installation

bun add -d bun-tsconfig-paths

Usage

With Bun's Bundler

Add the plugin to your Bun.build() configuration:

import tsconfigPaths from "bun-tsconfig-paths";

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

With Custom tsconfig Path

If your tsconfig.json is in a different location:

import tsconfigPaths from "bun-tsconfig-paths";

await Bun.build({
	entrypoints: ["./src/index.ts"],
	outdir: "./dist",
	plugins: [tsconfigPaths({ tsConfigPath: "./packages/app/tsconfig.json" })],
});

Example tsconfig.json

The plugin reads path aliases from your tsconfig.json:

{
	"compilerOptions": {
		"paths": {
			"*": ["./src/*"],
			"@/*": ["./src/*"],
			"@components/*": ["./src/components/*"],
			"@utils/*": ["./src/utils/*"]
		}
	}
}

With this configuration, you can use imports like:

import { Button } from "@components/Button";
import { formatDate } from "@utils/date";
