Step into a world where you never have to deal with portability and platform issues. Whether you're targeting web browsers, serverless platforms, chatbots, CLI, or multiple platforms simultaneously, eserstack ensures your code runs flawlessly everywhere.

📖 Overview

eserstack is a JavaScript toolkit designed to uphold best practices and enhance portability across different platforms.

Beyond being a toolkit, eserstack advocates for a philosophy that emphasizes writing code driven by algorithms, design and patterns, not by platform-specific implementation details.

While eserstack offers you a layer of abstraction that isolates you from the platforms, you can focus on your implementation. Don't worry about the rest, your solution will excel across diverse environments.

Every component of eserstack is designed to work in harmony, strives to offer you an intuitive and delightful development experience.

Our Goal / The Bigger Picture

We strive to run the following code seamlessly across all platforms we support:

import { Runtime, Context } from "@eser/runtime";

const home = (ctx: Context) => {
  return ctx.results.jsx(<h1>Hello there!</h1>);
};

const profile = (ctx: Context) => {
  const slug = ctx.input.param("id");
  const db = ctx.di`db`;

  ctx.logger.info(`Visiting the profile of ${slug}!`);

  return ctx.results.json(db.query("SELECT * FROM users WHERE slug=:slug", { slug }));
};

const router = (ctx: Context) => {
  switch (true) {
    case ctx.route.match("/"):
      return home(ctx);
    case ctx.route.match("/:id"):
      return profile(ctx);
    default:
      return ctx.results.notFound();
  }
};

const runtime = new Runtime();
runtime.ci.register("db", new DatabaseConnection());
runtime.listen(router); // or runtime.execute(fn);

Platform Support

Since the reason we started to build this project is the feeling of a lack of a JavaScript/TypeScript framework that is portable across many platforms, we're always looking for the widen this list. By adhering to WinterCG guidelines and TC39 standards, we strive to provide a framework that is portable across all these platforms.

...and all other platforms that comply with the WinterCG guidelines.
