A cors web worker (supports creating a Worker instance for scripts from different hosts). Can be used with webpack or other bundlers.
Install the package by running the following command in terminal:
npm install @deox/cors-workerThe module can be imported using import in ES Modules and require in Common JS as shown below:
ES Modules:
// index.ts
import { Worker } from "@deox/cors-worker";
// ...Common JS:
// index.cjs
const { Worker } = require("@deox/cors-worker");
// ...Following is an example of using this library with webpack:
Create a worker.ts as shown below:
// worker.ts
import { register } from "@deox/cors-worker/register";
export type Context = {
info: string;
};
const registered = register((ctx: Context) => ({
hello: () => `Hello from worker with info: ${ctx.info}`,
sum: (...numbers: number[]) => numbers.reduce((p, c) => p + c)
}));
export type Registered = typeof registered;Create a Worker instance in your entrypoint and utilize it:
// index.ts
import { Worker } from "@deox/cors-worker";
import { type Context, type Registered } from "./worker";
const context: Context = {
info: "This works!"
};
const worker = new Worker<Registered>(
new URL("./worker", import.meta.url),
{ context, name: "my-worker" }
);
// Call the methods :)
worker.call("hello").then(result => {
// Do something with result
console.log(result);
});
// Or use ES6 Proxy
worker.proxy.sum(20, 50, 30).then(result => {
// Do something with result
console.log(result);
});Note: It doesn't matter your registered methods are synchronous or asynchronous, the methods called using
Workerinstance will always return aPromisewhich resolves or rejects based on method logic.
