Lightning Web Component

Lightning web components (lwc) are custom HTML elements built using HTML and modern JavaScript.

This feature works when api version is >= 45.0

Create Lightning Web Component

Create lwc by clicking HaoIDE -> New -> New Lightning Web Component from the menu, and inputting the valid lwc name.

For better convenience, will create the lwc as LightningComponentBundle with three LwcResources -- HTML file, JavaScript file and configuration file under the component's folder.

myComponent
  ├──myComponent.html
  ├──myComponent.js
  └──myComponent.js-meta.xml

Add CSS File

From the component folder or file's sidebar context menu, click HaoIDE -> Create Lwc Style.

Add SVG Icon

From the component folder or file's sidebar context menu, click HaoIDE -> Create Lwc SVG.

Add Additional JavaScript File(s)

You can create Additional JavaScript files under the component's folder by yourself.

Notice:

These additional JavaScript files must be ES6 modules and must have names that are unique within the component’s folder.

Component Tests

You can create Jest tests files following the official guide by yourself:

To create Jest tests for a component, create a folder called __tests__ at the top level of the component’s folder. Save the tests inside the __tests__ folder.
Test files must have names that end in “.js”, and we recommend that tests end in “.test.js. You can have a single test file with all of your component tests, or you can have multiple files to organize related tests. Test files can be placed in sub folders.

Retrieve Bundle/File

Two Approaches:

  1. From the component folder or file's sidebar context menu, click HaoIDE -> Retrieve Lightning From Server.
  2. From the opened component file's context menu, click HaoIDE -> Retrieve From Server or HaoIDE -> Retrieve From This Server.

Deploy Bundle/File

Two Approaches:

  1. From the component folder or file's sidebar context menu, click HaoIDE -> Deploy Lightning From Server.
  2. From the opened component file's context menu, click HaoIDE -> Deploy To Server or HaoIDE -> Deploy To This Server.

Save Component File to Server

lwc's HTML markup, JavaScript code, CSS file, SVG resource, additional JS files can save to Salesforce as LightningComponentResource separately.

From the opened component file's context menu, click HaoIDE -> Deploy From Server or HaoIDE -> Save To Server. or simply press ctrl+alt+s(Windows).

If you cannot save certain file to server, try retrieving it from server first.

Notice: XML configuration file (js-meta.xml) cannot save to server since the Metadata API does not support it.

Destruct Component

Two Approaches:

  1. From the component folder or file's sidebar context menu, click HaoIDE -> Destruct Lightning From Server.
  2. From the opened component file's context menu, click HaoIDE -> Destruct From Server.
