Background

This library allows React developers to quickly and easily create a Cisco Spark experience within their apps. Here we provide basic components (e.g. buttons, text fields, icons) that reflect the styles and aesthetics of Spark, along with more complex, complete widgets, such as the Spark Space Widget.

The basic components are just presentational React https://github.com/facebook/react components, while our widgets leverage Redux https://github.com/reactjs/redux and the Spark Javascript SDK https://github.com/webex/spark-js-sdk.

Widgets

While many of our components are purely presentational, some have extended functionality that provide a piece of the full Cisco Spark experience. These fully self contained elements are called Widgets and are available here:

• Space Widget
• Recents Widget

Usage

A functional demo of both Space and Recents widgets can be loaded by simply running:

$ npm start

Install

Build From Source

1. Clone this repo using a git client (e.g. git clone https://github.com/webex/react-ciscospark.git)
2. Run npm install from the root of the repo. You will want to run this every time you pull down any new updates.
3. From the root of the repo, run the following to build the widget:

   npm run build

4. The built bundles are located at packages/node_modules/@ciscospark/PACKAGE_NAME/dist.

Version

Once a widget is bundled, the version number is available in the following ways:

• A comment at the top of each bundled file
• Programmatic access after a widget has been registered: window.ciscospark.widgetFn.{widgetName}.version (e.g. window.ciscospark.widgetFn.spaceWidget.version)
• Access after a widget has been instantiated: window.ciscospark.widget({widgetEl}).version (e.g. window.ciscospark.widget(document.getElementById('myWidget')).version)

Development

• stylelint currently ignores all node_modules directories, and will not lint our packages. Discussion: stylelint/stylelint#2236

Coding Style

We follow our Cisco Spark Web Styleguide when developing any web based libraries and tools. Please check it out and do your best to follow our norms when contributing to this codebase.

Code Verification

As a best practice, we provide a Sub-resource Integrity (SRI) hash for all of our CDN hosted distributable files. A manifest listing all of the files with associated integrity hashes can be found for the latest build, where {NAME} is the name of the widget at https://code.s4d.io/widget-{NAME}/production/manifest.json.

Manifest Example

{
  "version": "0.1.215",
  "files": [
     {
       "name": "bundle.js",
       "url": "https://code.s4d.io/widget-space/archives/0.1.120/bundle.js",
       "signature": "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",

    }
  ]
}

To find the SRI hash for a specific build of the widgets, you can use the following URL, replacing {VERSION} with the specific version you are looking for: https://code.s4d.io/widget-space/archives/{VERSION}/manifest.json.

Additionally, for those who want an additional layer of verification, a signature has been provided that is signed by a private key. You can use our public key to verify this signature. Here is example of the verification process using the nodeJS built-in cryto library:

const crypto = require('crypto');
function verifySignature({
  data,
  signature,
  publicKey
}) {
  // Verify that we signed correctly using public key
  const verify = crypto.createVerify('RSA-SHA384');
  verify.write(data);
  verify.end();

  // True if signature is verified
  return verify.verify(publicKey, signature, 'base64');
}
