* 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.

# Transport
|
|

|
|
|
|
The transport layer is responsible for communication between services.
|
|
|
|
## Features
|
|
- Pluggable transport implementations
|
|
- Secure and efficient communication
|
|
|
|
## Implementations
|
|
Supported transports include:
|
|
- HTTP (default)
|
|
- NATS (`go-micro.dev/v6/transport/nats`)
|
|
- gRPC (`go-micro.dev/v6/transport/grpc`)
|
|
- Memory (`go-micro.dev/v6/transport/memory`)
|
|
|
|
## Important: Transport vs Native gRPC
|
|
|
|
The gRPC **transport** uses gRPC as an underlying communication protocol, similar to how NATS or RabbitMQ might be used. It does **not** provide native gRPC compatibility with tools like `grpcurl` or standard gRPC clients generated by `protoc`.
|
|
|
|
If you need native gRPC compatibility (to use `grpcurl`, polyglot gRPC clients, etc.), you must use the gRPC **server** and **client** packages instead:
|
|
|
|
```go
|
|
import (
|
|
grpcServer "go-micro.dev/v6/server/grpc"
|
|
grpcClient "go-micro.dev/v6/client/grpc"
|
|
)
|
|
|
|
// Important: Server must be specified before Name
|
|
service := micro.NewService(
|
|
micro.Server(grpcServer.NewServer()),
|
|
micro.Client(grpcClient.NewClient()),
|
|
micro.Name("myservice"),
|
|
)
|
|
```
|
|
|
|
See [Native gRPC Compatibility](guides/grpc-compatibility.html) for a complete guide.
|
|
|
|
Plugins are scoped under `go-micro.dev/v6/transport/<plugin>`.
|
|
|
|
You can specify the transport when initializing your service or via env vars.
|
|
|
|
## Example Usage
|
|
|
|
Here's how to use a custom transport (e.g., gRPC) in your Go Micro service:
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"go-micro.dev/v6"
|
|
"go-micro.dev/v6/transport/grpc"
|
|
)
|
|
|
|
func main() {
|
|
t := grpc.NewTransport()
|
|
service := micro.NewService(
|
|
micro.Transport(t),
|
|
)
|
|
service.Init()
|
|
service.Run()
|
|
}
|
|
```
|
|
|
|
NATS transport:
|
|
```go
|
|
import (
|
|
"go-micro.dev/v6"
|
|
tnats "go-micro.dev/v6/transport/nats"
|
|
)
|
|
|
|
func main() {
|
|
t := tnats.NewTransport()
|
|
service := micro.NewService(micro.Transport(t))
|
|
service.Init()
|
|
service.Run()
|
|
}
|
|
```
|
|
|
|
## Configure via environment
|
|
|
|
```bash
|
|
MICRO_TRANSPORT=nats MICRO_TRANSPORT_ADDRESS=nats://127.0.0.1:4222 go run main.go
|
|
```
|
|
|
|
Common variables:
|
|
- `MICRO_TRANSPORT`: selects the transport implementation (`http`, `nats`, `grpc`, `memory`).
|
|
- `MICRO_TRANSPORT_ADDRESS`: comma-separated list of transport addresses.
