Next-public-ts NPM

next-public-ts

A webpack plugin to compile TypeScript files in the public folder of a Next.js project.\ I created this Webpack plugin because I wanted to use TypeScript in the public folder of my Next.js project but Next.js doesn't support this out of the box.

Features

Write your Service Workers and your Web Workers in TypeScript
Handle process.env.NEXT_PUBLIC_* in your TypeScript files
Compile and minify your TypeScript files
Auto-detect *.ts with autoDetect option and +public directory
Inject a SHA-1 hash of the file content into %checksum% variable in the compiled file
Support for CommonJS and ES modules

Installation

npm install --save-dev next-public-ts

Usage

Auto-detect `*.ts` files with `+public` directory

// next.config.js
const { NextPublicTsPlugin } = require("next-public-ts");

const nextConfig = {
  webpack(config, context) {
    config.plugins.push(
      new NextPublicTsPlugin({
        autoDetect: true,
      }),
    );
    return config;
  },
};

With `inputDir` and `outputDir` options

// next.config.mjs
import path from "node:path";
import { NextPublicTsPlugin } from "next-public-ts";

/**
 * @type {import('next').NextConfig}
 */
const nextConfig = {
  webpack(config, context) {
    config.plugins.push(
      new NextPublicTsPlugin({
        inputDir: path.join("src", "app", "+public"),
        outputDir: path.join("public"),
      }),
    );
    return config;
  },
};

export default nextConfig;
