If I try to use http-errors is get back on building

✘ [ERROR] Could not resolve "http-errors"

    src/index.ts:11:54:
      11 │ import {BadRequest, HttpError, MethodNotAllowed} from "http-errors";
         ╵                                                       ~~~~~~~~~~~~~

  You can mark the path "http-errors" as external to exclude it from the bundle, which will remove
  this error.

How to include the module properly?

What I did:

$ wrangler init req-test
 ⛅️ wrangler 2.0.12 (update available 2.0.15)

Using npm as package manager.

To start developing your Worker, run `cd req-test && npm start`
To publish your Worker to the Internet, run `npm run deploy`

$ cd req-test
$ npm install --save @types/http-errors

Than use this as src/index.ts :


import {BadRequest} from "http-errors";

export default {
  async fetch(
    request: Request,
    env: Env,
    ctx: ExecutionContext
  ): Promise<Response> {
    throw new BadRequest();
    return new Response("Hello World!");
  },
};

Try starting the worker with

$ wrangler dev

You installed the types for http-errors not the package it’s self. Try npm install --save npm install http-errors
