Stencil components in Vue

Stencil is not a JS framework. It is a compiler that produces a reusable web component that can be embedded anywhere else.

This is a step by step guide to consume a non-trivial stencil component in a Vue app.

The starter Vue app was created with Vue CLI.

0: Build a stenciljs component and publish it to npm

Creating your first stencil component is very easy and it is well documented here.

This example will consume two components:

1: Add the component(s) to the dependencies

Add the component to the app dependencies in package.json

// package.json

"dependencies": {
  ...
  "@openchemistry/molecule-vtkjs": "^0.1.9",
  "split-me": "^0.3.1"
}

2: Import the component(s)

Import the component in the main.js of the app:

import { defineCustomElements as defineMolecule } from '@openchemistry/molecule-vtkjs';
import { defineCustomElements as defineSplitMe } from 'split-me';

defineMolecule(window);
defineSplitMe(window);

3: Consume the component

To prevent Vue from complaining that your component has an unrecognized tag, add the following in main.js. Use either the full name, or regex if you want to capture a family of components.

Vue.config.ignoredElements = [
  "oc-molecule-vtkjs",
  "split-me"
];

It is now possible to use the tag provided by the stencil component in any template of the app.

<oc-molecule-vtkjs v-bind:cjson.prop="molecule" />

Appendix: Attribute vs Prop

oc-molecule-vtkjs has a property named cjson that expects an object (or a JSON.stringified object).

Strings can be passed directly as attributes to a stencil component.

<oc-molecule-vtkjs v-bind:cjson="moleculeStr" />

While this would work, it is probably a good idea to avoid the JSON.stringify() and JSON.parse() and directly pass the object itself to the component.

Vue provides a way to explicitly pass the object as a property rather than an attribute, it is as simple as adding .prop to the property name of the stencil component.

<oc-molecule-vtkjs v-bind:cjson.prop="molecule" />
