Vue CWL

Vue CWL provides a Vue component for the visualization of CWL (Common Workflow Language) workflows.

Motivation

Vue CWL uses the fantastic cwl-svg library behind the scenes, which you can also use directly. However, you might want to use Vue CWL because:

• You can use it directly in your HTML application, without setting up a compiler. You don't even need to use npm!
• If you're using Vue elsewhere in your application, Vue CWL will be much easier to integrate.

Installation (if using npm )

Install from npm:

npm install vue-cwl --save-dev

Or, if you want the latest development version, install from github:

npm install git+https://[e-mail]/TMiguelT/vue-cwl.git --save-dev

Integration

Vue CWL is exported as a UMD module, which means that you can either import it with a module loader, or import it directly in the browser.

If using webpack and npm:

import Vue from 'vue';
import Cwl from 'cwl-svg';
 
new Vue({
    el: '#vue',
    components: {
        cwl: Cwl
    }
})

You can now use the <cwl> tag in your template:

<cwl
    cwl-url="https://unpkg.com/cwl-svg@2.1.5/cwl-samples/fastqc.json"
></cwl>

If using no bundler, you can include Vue and Vue CWL using something like unpkg:

<div id="vue" style="width: 800px; height: 800px">
    <cwl
            cwl-url="https://unpkg.com/cwl-svg@2.1.5/cwl-samples/fastqc.json"
    ></cwl>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.6.10/vue.min.js"></script>
<script src="https://unpkg.com/vue-cwl/dist/index.js"></script>
<script>
    new Vue({
        el: '#vue',
        components: {
            cwl: vueCwl.default
        }
    });
</script> 

Usage

Vue CWL components currently accept 4 props:

• cwl:
  • type: Object
  • default: null
  • description: The JSON object representing the CWL workflow to render
• cwlUrl:
  • type: String
  • default: null
  • description: A URL to request for the initial CWL object from. Used as an alternative to the "cwl" prop`
• editingEnabled:
  • type: Boolean
  • default: false
  • description: True if the workflow is editable
• plugins:
  • type: Array
  • default: No plugins
  • description: A list of CWL plugins to use in the CWL rendering
