* test(harness): read agent plan from the scoped store
The store-scoping change moved an agent's plan from the default table
key agent/{name}/plan to its own table (database "agent", table {name},
key "plan"). The plan-delegate harness tests still read the old key and
failed with 'not found'; read through store.Scope(mem, "agent", name)
like the agent does.
* docs: orient agents-first across README, landing, and docs overview
Lead with agents (then services and flows), surface MCP + A2A as the
interop story, and frame agents as services. Landing hero and feature
grid reordered agents-first with an A2A gateway card.
* v6: module path go-micro.dev/v6, TLS secure by default, NewService
Cut v6. Three breaking changes, bundled so the major bump is paid once:
- Module path go-micro.dev/v5 -> go-micro.dev/v6 across all imports + go.mod.
- TLS verification on by default (was off). MICRO_TLS_SECURE removed;
MICRO_TLS_INSECURE=true opts out for self-signed/dev.
- micro.NewService(name, opts...) is the canonical service constructor,
symmetric with NewAgent/NewFlow; micro.New kept as a deprecated alias;
the old name-less NewService(opts...) removed. Generators emit NewService.
Also ports the JWT auth token provider in-module (go-micro.dev/v6/auth/jwt/token
on golang-jwt/jwt/v5), dropping the v5-pinned github.com/micro/plugins/v5/auth/jwt
and the deprecated dgrijalva/jwt-go.
Docs/README/landing updated to v6 and @latest; v5->v6 migration guide added;
CHANGELOG cut as [6.0.0]. Blog posts left at their historical versions.

# Hello World Example
|
|
|
|
The simplest go-micro service demonstrating core concepts.
|
|
|
|
## What It Does
|
|
|
|
This example creates a basic RPC service that:
|
|
- Listens on port 8080
|
|
- Exposes a `Greeter.Hello` method
|
|
- Returns a greeting message
|
|
- Demonstrates both programmatic and HTTP access
|
|
|
|
## Run It
|
|
|
|
```bash
|
|
go run main.go
|
|
```
|
|
|
|
The service will start and make test calls to itself, then wait for incoming requests.
|
|
|
|
## Test It
|
|
|
|
### Using curl
|
|
|
|
```bash
|
|
curl -X POST http://localhost:8080 \
|
|
-H 'Content-Type: application/json' \
|
|
-H 'Micro-Endpoint: Greeter.Hello' \
|
|
-d '{"name": "Alice"}'
|
|
```
|
|
|
|
Expected response:
|
|
```json
|
|
{"message": "Hello Alice"}
|
|
```
|
|
|
|
### Using the micro CLI
|
|
|
|
```bash
|
|
micro call greeter Greeter.Hello '{"name": "Bob"}'
|
|
```
|
|
|
|
## Code Walkthrough
|
|
|
|
1. **Define types** - Request and Response structures
|
|
2. **Implement handler** - The `Greeter` service with `Hello` method
|
|
3. **Create service** - Using `micro.NewService()` with options
|
|
4. **Register handler** - Link the handler to the service
|
|
5. **Run service** - Start listening for requests
|
|
|
|
## Key Concepts
|
|
|
|
- **RPC Pattern**: Method signature `func(ctx, req, rsp) error`
|
|
- **Service Discovery**: Automatic registration
|
|
- **Multiple Transports**: Works over HTTP, gRPC, etc.
|
|
- **Type Safety**: Strongly typed requests/responses
|
|
|
|
## Next Steps
|
|
|
|
- See [pubsub-events](../pubsub-events/) for event-driven patterns
|
|
- See [production-ready](../production-ready/) for a complete example
|
|
- Read the [Getting Started Guide](../../internal/website/docs/getting-started.md)
