Overview

Package aries provides a pluggable dependency framework, where implementors can customize primitives via Service Provider Interfaces (SPIs). The framework comes with a "batteries included" model where default primitives are included. The framework holds a context that can be used to create aries clients.

Usage:

// create the framework
framework := aries.New()

// get the context
ctx := framework.Context()

// initialize the aries clients
didexchangeClient, err := didexchange.New(ctx)
Example
package main

import (
	"fmt"

	"github.com/hyperledger/aries-framework-go/pkg/didcomm/transport"
	"github.com/hyperledger/aries-framework-go/pkg/storage"
)

func main() {
	// create the framework with user options
	framework, err := New(
		WithInboundTransport(newMockInTransport()),
		WithStoreProvider(newMockDBProvider()),
		WithTransientStoreProvider(newMockDBProvider()),
	)
	if err != nil {
		fmt.Println("failed to create framework")
	}

	// get the context from the framework
	ctx, err := framework.Context()
	if err != nil {
		fmt.Println("failed to create framework context")
	}

	fmt.Println("context created successfully")
	fmt.Println(ctx.ServiceEndpoint())

}

// mock inbound transport
type mockInTransport struct {
}

func newMockInTransport() *mockInTransport {
	return &mockInTransport{}
}

func (c *mockInTransport) Start(prov transport.Provider) error {
	return nil
}

func (c *mockInTransport) Stop() error {
	return nil
}
func (c *mockInTransport) Endpoint() string {
	return "http://server"
}

// mock DB provider
type mockDBProvider struct {
}

func newMockDBProvider() *mockDBProvider {
	return &mockDBProvider{}
}

func (c *mockDBProvider) OpenStore(name string) (storage.Store, error) {
	return nil, nil
}

func (c *mockDBProvider) CloseStore(name string) error {
	return nil
}

func (c *mockDBProvider) Close() error {
	return nil
}
Output:

context created successfully
http://server

Close frees resources being maintained by the framework.

func (*Aries) Context

func (a *Aries) Context() (*context.Provider, error)

Context provides a handle to the framework context.

func (*Aries) Messenger

func (a *Aries) Messenger() service.Messenger

Messenger returns messenger for sending messages through this agent framework TODO should use dedicated messenger interface instead of Outbound dispatcher [Issue #1058]

type Option

type Option func(opts *Aries) error

Option configures the framework.

func WithCrypto

func WithCrypto(c crypto.Crypto) Option

WithCrypto injects a crypto service to the Aries framework
