Core Element Template

This repository is a template for developers to create custom HTML elements for the core web3 framework. It includes a Go backend, an Angular custom element, and a full release cycle configuration.

Getting Started

1. Clone the repository:

   git clone https://github.com/your-username/core-element-template.git
   

2. Install the dependencies:

   cd core-element-template
   go mod tidy
   cd ui
   npm install
   

3. Run the development server:

   go run ./cmd/demo-cli serve
   

   This will start the Go backend and serve the Angular custom element.

Building the Custom Element

To build the Angular custom element, run the following command:

cd ui
npm run build

This will create a single JavaScript file in the dist directory that you can use in any HTML page.

Usage

To use the updater library in your Go project, you can use the UpdateService.

GitHub-based Updates

package main

import (
	"fmt"
	"log"

	"github.com/snider/updater"
)

func main() {
	config := updater.UpdateServiceConfig{
		RepoURL:        "https://github.com/owner/repo",
		Channel:        "stable",
		CheckOnStartup: updater.CheckAndUpdateOnStartup,
	}

	updateService, err := updater.NewUpdateService(config)
	if err != nil {
		log.Fatalf("Failed to create update service: %v", err)
	}

	if err := updateService.Start(); err != nil {
		fmt.Printf("Update check failed: %v\n", err)
	}
}

Generic HTTP Updates

For updates from a generic HTTP server, the server should provide a latest.json file at the root of the RepoURL. The JSON file should have the following structure:

{
  "version": "1.2.3",
  "url": "https://your-server.com/path/to/release-asset"
}

You can then configure the UpdateService as follows:

package main

import (
	"fmt"
	"log"

	"github.com/snider/updater"
)

func main() {
	config := updater.UpdateServiceConfig{
		RepoURL:        "https://your-server.com",
		CheckOnStartup: updater.CheckAndUpdateOnStartup,
	}

	updateService, err := updater.NewUpdateService(config)
	if err != nil {
		log.Fatalf("Failed to create update service: %v", err)
	}

	if err := updateService.Start(); err != nil {
		fmt.Printf("Update check failed: %v\n", err)
	}
}
