Replace the direct exec-based restart with a spawned watcher process: - Add hidden --watch-pid flag for internal use - spawnWatcher() spawns background process before update - watchAndRestart() polls for parent death, then restarts binary - Uses signal 0 on Unix to check if process is alive - Windows fallback spawns new process and exits This approach is safer because: - Parent exits cleanly before restart (no file locking issues) - Watcher is detached from parent process group - Works reliably across platforms Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> |

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
-
Clone the repository:
git clone https://github.com/your-username/core-element-template.git -
Install the dependencies:
cd core-element-template go mod tidy cd ui npm install -
Run the development server:
go run ./cmd/demo-cli serveThis 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)
}
}
