SWDEV

Runtime transfome by Service Worker and Deno(PoC).

How to use

# install
$ deno install -qAf --unstable https://deno.land/x/swdev/swdev.ts

$ swdev init myapp
$ cd myapp
$ swdev serve

open http://localhost:7777

CAUTION: port:7777 register service-worker. Unregister service-worker after develop.

How to develop

$ deno run -A --unstable swdev-dev.ts prebuild --client --worker # build __swdev-client and __swdev-server
$ deno run -A --unstable serve.ts examples/react --local # run

Concepts

  • Transform and cache in service-worker (typescript and svelte)
  • Cache bursting by file change event
  • Safe file read / write by deno permissions
  • Use deno semantics in frontend
  • Edit itself in browser
  • Bundle for production

Install

$ swdev init swdev-app
$ cd swdev-app
$ swdev serve

Experimental Read/Write via websocket`

Run with --allow-write flag.

$ swdev serve --allow-write

// declare to touch
declare const DenoProxy: {
  exec: any;
};

// READ
console.log(await DenoProxy.exec("readTextFile", "index.html"));
// WRITE: need --allow-write
await DenoProxy.exec("writeTextFile", "foo.ts", "export default 1;");

These features are provided by /__swdev_client.js

Experimental Command Run`

Run with --allow-run flag.

$ swdev serve --allow-run

// declare to touch
declare const DenoProxy: {
  exec: any;
};
