How to configure the web part icon in Spfx

Here we will see how to define a web part icon in SPFx preconfigured web part by using the HelloWorld project.

If we are creating a web part, the component’s icon should be self-explanatory. When SharePoint Framework Client Web Parts are added to a page, the icon and title are shown. The icon assists end users in forming an opinion on the web part.

In the below screenshot, you can see the below HelloWorld web part, which is defined as the default page icon.

The default icon displayed in the list for our web component. The icon is a pre-defined entry in the web part manifest.

In the below-preconfigured Entries, you can see the ‘officeFabricIconFontName’ property set as Page, which allows you choose to an icon from the Fluent UI. You can refer to the list of icons.


  "preconfiguredEntries": [{
    "groupId": "5c03119e-3074-46fd-976b-c60198311f70", 
    "group": { "default": "Advanced" },
    "title": { "default": "HelloWorld" },
    "description": { "default": "HelloWorld description" },
    "officeFabricIconFontName": "Page",
    "properties": {
      "description": "HelloWorld"
    }
  }]
}

Now to change the web part icon, we can choose an icon from the Fluent UI icons overview page, copy its name and paste it, as the value of ‘officeFabricIconFontName’ property in the manifest HellowWorld web part.

Now open the src\webparts\helloWorld\HelloWorldWebPart.manifest.json file and change the value of ‘officeFabricIconFontName‘ property, to ‘Balloons’. Here is the code you can refer to:

"preconfiguredEntries": [{
    "groupId": "5c03119e-3074-46fd-976b-c60198311f70", // Advanced
    "group": { "default": "Advanced" },
    "title": { "default": "HelloWorld" },
    "description": { "default": "HelloWorld description" },
    "officeFabricIconFontName": "Balloons",
    "properties": {
      "description": "HelloWorld"
    }
  }]

Now run the project by using the below command and you can see the web part icon is changed from ‘Page’ to ‘Balloons’.

How to add an external web part icon in spfx

Here we will see how to add an external web part icon in the spfx preconfigured Entries web part.

If no matching picture is found in the Office UI Fabric options, we may utilize our custom image to be presented as an icon. Any external icon can be supplied as an absolute URL in the iconImageUrl field.

Before we manifest the code in the preconfiguredEntries web part, first we need to download the image from the web based on your project requirement. And then upload the image to the SharePoint image library (e.g. “https://tsinfotechnologies.sharepoint.com/sites/developer/Site%20Image/people.png”), and the absolute path is supplied in the iconImageUrl field of the web component manifest. Please remove the officeFabricIconFontName attribute from the web component manifest.

Once you copy the path, open the src\webparts\helloWorld\HelloWorldWebPart.manifest.json file. and change the value of ‘iconImageUrl‘ in preconfigured entries code:

"preconfiguredEntries": [
    {
      "groupId": "5c03119e-3074-46fd-976b-c60198311f70", 
      "group": {
        "default": "Other"
      },
      "title": {
        "default": "Hello World"
      },
      "description": {
        "default": "Shows current weather in the given location"
      },
      "iconImageUrl": "https://tsinfotechnologies.sharepoint.com/sites/developer/Site%20Image/people.png",
      "properties": {
        "location": "India"
      }
    }
  ]

Now run the project by using the below command and you can see the web part icon is an image.

gulp serve
configure web part image icon in spfx
configure web part image icon in spfx

This is how to add an external web part icon in the SharePoint framework (spfx).

How to define spfx client side web part image by using base64-encoded image

Here we will see how to define a web part image by using the base64-encoded image.

Why do we need to use the base64-encoded image?

Instead of supplying an absolute URL to the image file stored with other web part assets when utilizing a custom image, you may have your picture base64-encoded and use the base64 string instead of the URL.

How to use a base64-encoded image in the pre-configured image?

As there is a number of services available online to use the value of the base64-encoded image, and you can see the tools I have used.

So firstly encode the image, and then copy the base64 string and paste it into the web component manifest’s iconImageUrl attribute.

The below base64 string value of iconImageUrl properties is too large, so I have added ‘…’. So you can see the base 64 string value file of the image I have used.

"preconfiguredEntries": [
    {
      "groupId": "5c03119e-3074-46fd-976b-c60198311f70", 
      "group": {
        "default": "Other"
      },
      "title": {
        "default": "Hellow World"
      },
      "description": {
        "default": "Welcome to SPFx"
      },
      "iconImageUrl":"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAgAAAAIACAYAAAD0eNT6AAAABHNCSVQICAgIfAhkiAAAAAlwSFlzAAAOxAAADsQBlSsOGwAAABl0RVh0U29mdHdhcmUAd3d3Lmlua3NjYXBlLm9yZ5vuPBoAACAASURBVHic7J13dFzF2f8/26vKqnfJkiXZcpN77xVTDKFDIJQ0IIGQYEra701CSIITkgBJyEs6hFBCCL0YjLHBxr1iS3KX1Xuvq93fH0J5g2zZe9vuXWk...",
