Edge Compute Quick Start

Tutorial Objectives

This tutorial covers learning the basic Edge Compute development workflow.

Prerequisites

A Telnyx account with API access - Sign up here if needed.
Command line familiarity - Requires Terminal (macOS/Linux) or Command Prompt (Windows).
Time requirement - This guide takes approximately 5 minutes to complete.

Install the CLI

Download Binary

Check out the edge-compute repo and download the latest release from the releases page. Extract the archive and add the binary to your PATH: Example for Linux/macOS:

# Download and extract
tar -xzf telnyx-edge-*.tar.gz

# Install to system PATH
sudo mv telnyx-edge /usr/local/bin/

# Verify installation
telnyx-edge --help

Authenticate

Option 1: OAuth (Recommended)

Authenticate using OAuth with your Telnyx account:

telnyx-edge auth login

This will open your browser to complete authentication.

Option 2: API Key

Alternatively, authenticate with a Telnyx API key:

telnyx-edge auth api-key set YOUR_API_KEY

Verify Authentication

Check your authentication status:

telnyx-edge auth status

Create a Function

Create a simple “Hello World” function. Choose your preferred language:

Go
Python
Java (Quarkus)

telnyx-edge new-func --language=go --name=hello-world

This creates a new directory with the function:

hello-world/
├── func.toml    # Function configuration
├── go.mod       # Go dependencies
└── handler.go   # Your function code

Function Code

The generated Go function uses package function with a Handle function:

package function

import (
    "encoding/json"
    "io"
    "log"
    "net/http"
)

type Response struct {
    Message string `json:"message"`
    Status  string `json:"status"`
}

func Handle(w http.ResponseWriter, r *http.Request) {
    log.Printf("Serving request: %s %s", r.Method, r.URL.Path)

    response := Response{
        Message: "Hello from Telnyx Edge Compute!",
        Status:  "success",
    }

    w.Header().Set("Content-Type", "application/json")
    json.NewEncoder(w).Encode(response)
}

telnyx-edge new-func --language=python --name=hello-world

This creates a new directory with the function:

hello-world/
├── function/        # Your function code
│   └── __init__.py
├── pyproject.toml   # Python dependencies
└── func.toml        # Function configuration

Function Code

The generated Python function uses ASGI protocol with a factory pattern:

# function/func.py
import json

def new():
    """Factory that returns a Function instance"""
    return Function()

class Function:
    async def handle(self, scope, receive, send):
        # Parse the request
        method = scope.get("method", "GET")
        path = scope.get("path", "/")

        # Build response
        response = {
            "message": "Hello from Telnyx Edge Compute!",
            "status": "success"
        }

        # Send response using ASGI protocol
        await send({
            "type": "http.response.start",
            "status": 200,
            "headers": [
                [b"content-type", b"application/json"],
            ],
        })
        await send({
            "type": "http.response.body",
            "body": json.dumps(response).encode(),
        })

The entry point is new() which returns a Function instance.

telnyx-edge new-func --language=quarkus --name=hello-world

This creates a new directory with the function:

hello-world/
├── src/main/java/    # Your function code
├── pom.xml           # Maven dependencies
└── func.toml         # Function configuration

Function Code

The generated Java function uses Quarkus Funqy with Input/Output beans:

package functions;

import io.quarkus.funqy.Funq;

public class Function {

    @Funq
    public Output function(Input input) {
        String defaultMessage = "Hello from Telnyx Edge Compute!";
        
        if (input == null || input.getMessage() == null) {
            return new Output(defaultMessage);
        }
        
        return new Output(input.getMessage());
    }
}

Deploy the Function

Navigate to the function directory and deploy:

cd hello-world
telnyx-edge ship

The CLI will:

Validate your function structure.
Check authentication.
Package your function files.
Upload to Telnyx Edge infrastructure.
Deploy across edge locations.

You’ll see output like:

Deploying function 'hello-world'...
✓ Function validated successfully
✓ Authentication verified
✓ Files packaged (2.3 KB)
✓ Upload complete
✓ Function deployed successfully

Function ID: func-abc123def456
Status: Active

Test the Function

Your function is now deployed and accessible via HTTP. Functions are accessible at URLs following this pattern: https://{funcName}-{orgId}.telnyxcompute.com Test your deployed function:

curl https://hello-world-abc123.telnyxcompute.com \
  -H "Content-Type: application/json" \
  -d '{"test": "data"}'

Response:

{
  "message": "Hello from Telnyx Edge Compute!",
  "status": "success"
}

Success! The Function is Live

Your function is now running and ready to handle HTTP requests. Functions automatically scale based on demand.

Function Anatomy

Every Telnyx Edge Compute function consists of three essential components:

Function Code

The main application code that handles HTTP requests and responses:

// Go example
package function

import (
    "encoding/json"
    "net/http"
)

func Handle(w http.ResponseWriter, r *http.Request) {
    json.NewEncoder(w).Encode(map[string]string{
        "message": "Hello from the edge",
    })
}

# Python example
class Function:
    async def handle(self, scope, receive, send):
        await send({
            "type": "http.response.start",
            "status": 200,
            "headers": [[b"content-type", b"application/json"]],
        })
        await send({
            "type": "http.response.body",
            "body": b'{"message": "Hello from the edge"}',
        })

// Java (Quarkus Funqy) example
package functions;

import io.quarkus.funqy.Funq;

public class Function {
    @Funq
    public Output function(Input input) {
        return new Output("Hello from the edge");
    }
}

Runtime Dependencies

Language-specific dependency files that define required packages:

// go.mod (Go)
module my-edge-function

go 1.21

# pyproject.toml (Python)
[project]
name = "my-edge-function"
version = "0.1.0"
dependencies = []

<!-- pom.xml (Java/Quarkus) -->
<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-funqy</artifactId>
</dependency>

Function Configuration

The func.toml file that defines deployment and runtime configuration:

[edge_compute]
func_id = "func-abc123def456"
func_name = "hello-world"

[env_vars]
MY_KEY = "VAL"

Next Steps

Now that your function is deployed, explore these topics to go deeper:

Runtime APIs - Request/response patterns and the platform interface.
Execution Model - Function lifecycle, cold starts, and container behavior.
Configuration - Environment variables, secrets, and bindings.
Local Development - Build, test, and debug functions locally.
CLI Reference - All available CLI commands.
