Key Features of Encore
Backend Framework
Encore's Backend Framework, available for both TypeScript and Go, enables developers to define resources like services, databases, cron jobs, and Pub/Sub topics using type-safe objects. This abstraction allows developers to focus on the application's behavior rather than specific cloud service configurations.
- Type-Safe Resources: Define services and infrastructure as type-safe objects in your application code.
- Automatic Boilerplate Generation: Encore generates the necessary infrastructure code, reducing manual configuration tasks.
- Cross-Cloud Portability: Build applications that are portable across cloud providers without needing separate configuration files.
Local Development Environment
Encore's local development environment provides a robust set of tools for building and testing applications:
- Match with Cloud: The local environment is designed to be a true reflection of your cloud setup, ensuring consistency across development stages.
- Type-Safe Communication: Enjoy cross-service type-safety and auto-complete features in your IDE.
- Secrets Management: Securely manage secrets across different environments.
- Tracing and Debugging: Access built-in tracing tools to diagnose issues and optimize performance.
Cloud Platform
Encore’s cloud platform automates the deployment and management of your application infrastructure, reducing the complexity of DevOps tasks:
- Automatic Infrastructure Provisioning: Connect your cloud account, and Encore will handle the provisioning of compute resources, databases, and more.
- DevOps Tools: Includes features like automatic least-privilege IAM, infrastructure tracking, and cost analytics.
- Service Catalog and API Documentation: Automatically generates comprehensive API documentation and service catalogs.
How Encore Works
Encore simplifies backend development by providing a unified approach to managing infrastructure and application logic. Here's how it works:
Example: Hello World
Encore makes defining microservices and API endpoints straightforward. Here’s a simple "Hello World" example using both TypeScript and Go:
TypeScript:
import { api } from "encore.dev/api";
export const get = api(
{ expose: true, method: "GET", path: "/hello/:name" },
async ({ name }: { name: string }): Promise<Response> => {
const msg = `Hello ${name}!`;
return { message: msg };
}
);
interface Response {
message: string;
}
Go:
package hello
//encore:api public path=/hello/:name
func World(ctx context.Context, name string) (*Response, error) {
msg := fmt.Sprintf("Hello, %s!", name)
return &Response{Message: msg}, nil
}
type Response struct {
Message string
}
Example: Using Pub/Sub
Encore’s Pub/Sub capabilities are equally simple to implement. Here’s how to set up a Pub/Sub topic in TypeScript and Go:
TypeScript:
import { Topic } "encore.dev/pubsub"
export interface SignupEvent {
userID: string;
}
export const signups = new Topic<SignupEvent>("signups", {
deliveryGuarantee: "at-least-once",
});
Go:
import "encore.dev/pubsub"
type User struct { /* fields... */ }
var Signup = pubsub.NewTopic[*User]("signup", pubsub.TopicConfig{
DeliveryGuarantee: pubsub.AtLeastOnce,
})
// Publish messages by calling a method
Signup.Publish(ctx, &User{...})
