Custom component

Build HTML/CSS/JS, React, Vue, Angular components

What is a Custom Component?

For very specific pages you can create your own custom Component based on HTML/CSS, React, Angular, Vue, or any other framework and integrate it into the Jet Admin interface. Writing your own custom JS/CSS/HTML has no limits in implementing any page you need.
To integrate your custom Component with Jet Admin data you can use the Jet Admin SDK library.

Create a HTML/CSS Component

You can create your own Custom HTML components and pass values to them from anywhere else in the application via parameters. A short demo video on how to do this:

Create a Custom Component

In this tutorial, we'll show you how to create a sample Custom Сomponent that you can, later on, extend to satisfy whatever needs you have.

1. Create your Custom component project (playground) or clone an example

A Custom Component uses Web Component specification to integrate any JS-based component to Jet Admin – this allows you to use any Frameworks and Libraries you like as long as you create them as custom Web Components. So it can be React, Angular, Vue. js-based components, or any other.
First, you need to create a Custom Component project where you can develop and test it. This project will be your playground for creating Custom Components. It will work the same way as on Jet Admin but will make your development easier so that you can use your favorite IDE and environment. To make it simpler, you can use some of our ready-to-use starter projects on GitHub or use them as a reference:
For example, here's an example of cloning React and preparing it for work:
git clone [email protected]:jet-admin/jet-flex-view-react-example.git
cd jet-flex-view-react-example
npm install

2. Run your project

After you created your project and cloned an example, make sure it works by running this command (or any other you use):
npm run start
http://localhost:3000/
The project works fine, so you can start developing your Custom Component. But before that, read the following step if you need the Jet Admin API integration.
Consider the following limitation while developing:
  • You can't use change URL inside Custom Component since component is embed inside Jet Admin view
  • Consider incapsulating styles inside your view, not use global styles

3. (optional) Set up Jet API integration

To integrate your custom Custom Component with Jet Admin data and API, you can use Jet Admin SDK library. To start using it, you would have to install it first:
npm install jet-admin-sdk
To work with API and perform queries, the SDK needs to know which Project you are working with and your Access Token. When a Custom Component is uploaded to production, it will fetch these automatically, but for development, you need to specify it manually, as shown below:
import { getPublicApiService } from 'jet-admin-sdk';
if (!process.env.NODE_ENV || process.env.NODE_ENV === 'development') {
getPublicApiService().projectsStore.setCurrent('YOUR_PROJECT_UNIQUE_NAME');
getPublicApiService().authService.tokenLogin('YOUR_USER_TOKEN');
}
  • YOUR_PROJECT_UNIQUE_NAME – can be taken from URL of your project on Jet Admin
  • YOUR_USER_TOKEN – can be taken from cookie token on https://app.jetadmin.io/
That's it! You can now use Jet Admin API through PublicApiService. For example:
import { getPublicApiService } from 'jet-admin-sdk';
getPublicApiService().currentUserStore.get().subscribe(result => {
if (result) {
console.log('Current User is ' + result.username);
} else {
console.log('Failed to get Current User');
}
});

4. Upload your Custom Component to Jet Admin

Once you're finished with your Custom Component or just want to test it in a real application, you need to upload it. Build your project first:
npm run build
Usually, it will create your build files in dist folder, but it can differ for your environment. To upload your Custom Component to Jet Admin, you need to upload a .zip file with your build files. Go to dist folder and compress all the contents to a single .zip file.
Now go to Jet Admin and create Custom Component as shown below.
You will need to specify the following settings and click the Save button:
  • Compiled custom elementzip file containing your build files of Custom Component.
  • Custom element tag name – tag name that you used for Web Component inside your Custom Component project. Should pre prefixed with "jet-" and has dash-case. Also each of your Custom Component should have unique tag names across your Jet Admin project.
  • Files to include into page – in order for your Custom Component to work JS and maybe CSS files should be included. You should check which files from your zip files should be included. The order of loading can be changed. These files will be included only once when Custom Component should be displayed and after inclusion they must defined custom element with tag name the same as you specified for Custom element tag name.
That's a wrap. Feel free to test your Jet Admin now. If you want to update it later, upload a new .zip file inside Custom Component.

Set Custom Component Inputs

You can specify Inputs to pass data inside Custom Component from Jet Admin if you have defined custom attributes for your Custom Component (Examples from GitHub include them already).
For Angular: Please note that Angular changes Inputs names to dash-case when creating Custom Element (https://angular.io/guide/elements#mapping)

Use Custom Component Outputs

You can specify Outputs to take from your Custom Component and use their values in other Jet Admin components. For such cases you should set Outputs inside your Custom Component by sending CustomEvent with Output name and its value in detail field (Examples from GitHub include it already).
Then you can create Output and set its name and use them for other components (for example set Text Field value to Custom Component Output).
