IMPORT-RELOAD

Module reloading for Node.js

import-reload is a NPM module that lets you live-relaod modules when they are modified without requiring server restart.

INSTALL

$ npm install import-reload

USAGE

Example

// foo.ts
export const foo = { bar: 1 };

// main.ts
import { reload } from "import-reload";

const foo = await reload(
  () => import("./foo"),
  Foo => Foo.foo
);

console.log(foo.bar); // outputs 1

Then modify foo.ts:

// foo.ts
export const foo = { bar: 2 };

Back in main:

console.log(foo.bar); // outputs 2

API

reload<U, T extends object>(importFn: () => Promise<U>, extractFn: (module: U) => T): Promise<T>;

importFn should use the dynamic import function, e.g. () => import("./module).

extractFn takes in the module returned by the import and returns the object to be used by the program.
