Getting Started

npm install simplerjs --save 

yarn add simplerjs    

API Reference

import { getProgram } from 'simplerjs';

const program = getProgram(gl,vertexSource,fragmentSource);

Parameter Description

the getProgram function need three parameters.they are gl context for webgl,you can get it by:

const gl = canvas.getContext('webgl');

the second and third parameter are two script id of webgl shaders, just like:

<script id="vertexShader" type="shader">
        attribute vec2 v_position;
        uniform vec2 v_resolution;
        varying vec4 v_color;

        void main(){
           vec2 one = v_position / v_resolution;
           vec2 two = one * 2.0;

           vec2 res = two - 1.0;

           gl_Position = vec4(res, 0, 1);
           v_color = vec4(one * 0.9, 0.5, 1);
        }
    </script>

    <script id="fragmentShader" type="shader">
        precision mediump float;
        varying vec4 v_color;

        void main(){
            gl_FragColor = v_color;
        }
    </script>

the second and third parameters are vertexShader and fragmentShader. if everything is ok, a webgl program instance will be back.
