Installation

With npm

npm install canvas-datagrid

With bower

bower install canvas-datagrid

Place the single source file ./dist/canvas-datagrid.js in your web page using a script tag that points to the source or use webpack.

<script src="dist/canvas-datagrid.js"></script>

Alternatively, instead of downloading and installing, you can link directly to an NPM CDN like unpkg.com.

<script src="https://unpkg.com/canvas-datagrid"></script>

A function will be added to the global scope of the web page called canvasDatagrid as well as module loader definitions.

Getting started

Works with webpack, without webpack or as a web component. No matter how you load it, canvasDatagrid is declared in the global scope.

Canvas-datagrid is a Web Component when in a compatible browser, otherwise it is a <canvas> tag.

Using pure JavaScript

var grid = canvasDatagrid();
document.body.appendChild(grid);
grid.data = [
    {col1: 'row 1 column 1', col2: 'row 1 column 2', col3: 'row 1 column 3'},
    {col1: 'row 2 column 1', col2: 'row 2 column 2', col3: 'row 2 column 3'}
];

Using web component

<canvas-datagrid class="myGridStyle">[
    {"col1": "row 1 column 1", "col2": "row 1 column 2", "col3": "row 1 column 3"},
    {"col1": "row 2 column 1", "col2": "row 2 column 2", "col3": "row 2 column 3"}
]</canvas-datagrid>

• XHR data paging demo - Jeopardy Questions API. Thanks to jservice for the use of the free paging API. Note: you must "load unsafe scripts" or relevant command to allow HTTPS (github) to make XHR requests to HTTP (Jeopardy Questions API). There is nothing unsafe about this.
