Source Code

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 a bundler, without one 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>

See Using with Vue for a full component, and Using with React for React.

Using TypeScript

Type declarations are included. Import the factory and, when you need them, the instance and argument types:

import canvasDatagrid, {
  type canvasDatagrid as CanvasDatagrid,
  type CanvasDatagridArgs,
} from 'canvas-datagrid';

The declarations are generated from JSDoc and are not strict-clean yet, so keep skipLibCheck: true in your tsconfig.json.

Building & Testing

To install development dependencies. Required to build or test.

npm install

To build production and debug versions:

npm run build

To build documentation:

npm run build:docs

To build types:

npm run build:types

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

npm test

Windows 10 WSL Testing

This is info for wsl version 1. v2 seems to be different.

• CHROME_BIN needs to be set to the location of your Google Chrome exe in Windows. (e.g. /mnt/c/Program Files (x86)/Google/Chrome/Application/chrome.exe) in WSL, export CHROME_BIN='path/to/chrome'
• Chrome needs access to karma's temp folder.
  • Create a tmp folder on the same Windows drive as your repo.
  • set TEMP to a folder that exists on the same Windows drive as your repo. (matching capitalization probably matters) in WSL, export TEMP='/Temp/karma', if your repo is on drive C, then create folder C:\Temp\karma
• karma.conf.js needs to be edited
  • Change the browser from ChromeHeadless to Chrome
  • Modify to run ChromeHeadless without sandboxing. This is not ideal, but it seems to be necessary in WSL and Linux containers (see also)
    • Add a custom launcher

      customLaunchers: {
        ChromeHeadlessNoSandbox: {
            base: 'ChromeHeadless',
            flags: ['--no-sandbox']
        }
      }

    • Change the browser from ChromeHeadless to ChromeHeadlessNoSandbox
