Mandelbrot Set
|
||||
==============
|
||||
|
||||
An [AssemblyScript](http://assemblyscript.org) example. Renders the Mandelbrot set to a canvas. Compiles to ~350 bytes of optimized WASM.
|
||||
|
||||
Instructions
|
||||
------------
|
||||
|
||||
First, install the development dependencies:
|
||||
|
||||
```
|
||||
$> npm install
|
||||
```
|
||||
|
||||
Now, to build [assembly/index.ts](./assembly/index.ts) to an untouched and an optimized `.wasm` including their respective `.wat` representations, run:
|
||||
|
||||
```
|
||||
$> npm run asbuild
|
||||
```
|
||||
|
||||
Afterwards, run `npm run server` to start a <a href="http://127.0.0.1:8080">local server</a>. Should also automatically launch a browser.
