ts-serve

TypeScript + ES Modules

Transpile TypeScript on the fly and deliver it from your server as ES Modules.

import { serve } from "https://deno.land/std@0.144.0/http/mod.ts";
import { serveDirWithTs } from "./mod.ts";

serve((request) => serveDirWithTs(request));

// index.html
<script src="./main.ts" type="module"></script>;

// main.ts
console.log(1);

The URL remains *.ts and will not be rewritten. That is, import "./foo.ts" and <script src="./foo.ts" type="module"> work.
You can use import "./foo.ts", which has the same syntax as Deno. This means that you can use the completion and diagnostic features by installing Deno and the Deno extension in the editor.

Usage

As oak middleware:

import { Application } from "https://deno.land/x/oak@v10.6.0/mod.ts";
import { tsMiddleware } from "./mod.ts";

const app = new Application();
app.use(tsMiddleware); // use middleware and transpile TS code.

// serve static file
app.use(async (ctx, next) => {
  try {
    await ctx.send({ root: "./" });
  } catch {
    await next();
  }
});
await app.listen({ port: 8000 });

As a replacement for the serveDir function in the Deno standard library:

import { serve } from "https://deno.land/std@0.144.0/http/mod.ts";
import { serveDirWithTs } from "./mod.ts";

serve((request) => serveDirWithTs(request));

As a replacement for the serveFile function in the Deno standard library:

import { serve } from "https://deno.land/std@0.144.0/http/mod.ts";
import { serveFileWithTs } from "./mod.ts";

serve((request) => serveFileWithTs(request, "./mod.ts"));
