Installation

With npm

npm 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" data="data can go here too">[
    {"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>

or

var grid = document.createElement('canvas-datagrid');
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 Vue

<canvas-datagrid :data.prop="[{"col1": "row 1 column 1"}]"></canvas-datagrid>

Note about XHR paging demo: Thanks to jservice for the use of the free paging API. 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.

Building & Testing

npm install

To build production and debug versions.

npm run build-all

To build production version.

npm run build-prd

To build debug version.

npm run build-dev

To build debug version anytime a file in ./lib changes.

npm run build-watch

To build documentation.

npm run build-docs

To run tests. Note: Headless tests will mostly fail due to lack of headless canvas pixel detection support. Use VM testing or your browser.
