deeplink is a comprehensive solution for short link generation, click tracking, and Open Graph (OG) preview pages built in Go. Designed with flexibility in mind, this project supports pluggable processors and offers the option to use Redis or in-memory storage, making it suitable for a variety of use cases.

Key Features

• Short Link Creation: Simplify URLs for easier sharing and tracking.
• Click Tracking: Monitor link engagement with detailed tracking capabilities.
• OG Preview Pages: Enhance link previews with customizable metadata.
• Flexible Architecture: Leverage pluggable processors for extended functionality.
• Storage Options: Choose between Redis and in-memory storage solutions.

Getting Started

Implementing your own short link generation service is straightforward using the following example:

svc, err := deeplink.New(deeplink.Config{
    BaseURL:     "https://link.example.com",
    Store:       deeplink.NewMemoryStore(),
    TemplateDir: "templates/default",
})
if err != nil {
    log.Fatal(err)
}
svc.Register(deeplink.RedirectProcessor{})

mux := http.NewServeMux()
mux.Handle("/", svc.Handler())
mux.HandleFunc("GET /hello", yourHandler)

log.Fatal(http.ListenAndServe(":8090", mux))

Usage Example

To create a short link, utilize the following CURL command:

curl -X POST http://localhost:8090/shorten \
  -H 'Content-Type: application/json' \
  -d '{"type":"redirect","url":"https://example.com/docs","title":"Docs"}'

Open the returned short_url in a web browser to access the shortened link.

Custom Processors

Developers can create custom processors by implementing the Processor interface:

type Processor interface {
    Type() string
    Process(ctx context.Context, link *Link) error
}

For custom preview data, the Previewer interface can be implemented as follows:

type Previewer interface {
    Preview(link *Link) any
}

See the example/custom directory for a working example and tests.

Standalone Server

A fully functional Redis-backed server can be quickly initiated using Docker:

docker compose up -d
go run ./cmd/deeplink

API Endpoints

The service provides several HTTP routes to interact with:

For customizable routing based on platforms, additional paths are available related to app store redirects and file serving from the template directory. Support for iOS Universal Links and Android App Links can be achieved by placing the respective files in the specified template directory.

Configuration

Several environment variables aid in configuring the deeplink server, including:

Customization of Templates

The default templates located in templates/default/ can be altered for personalized branding and messaging, utilizing key fields from the Link data structure, including URL, Title, Description, and ImageURL.

Development

For developers looking to contribute or modify the project:

go test ./...          # Execute tests

go run ./cmd/deeplink  # Start standalone server with Redis
