Variables

var ErrServerPanic = errors.New("server panic")

ErrServerPanic is returned when the server panicked.

Functions

func IdentityFromContext

func IdentityFromContext(ctx context.Context) openid.Token

IdentityFromContext returns the identity from context as an OpenID token. If there is no token in the context it returns an empty (anonymous) openid token.

func New

func New[RO, RW any](
	cfg Config,
	logs *zap.Logger,
	ro RO, roc ConstructHandler[RO],
	rw RW, rwc ConstructHandler[RW],

	valr *validate.Interceptor,
	logr *Logger,
	rcvr *Recoverer,
	auth *Auth,
	rotx ROTransacter,
	rwtx RWTransacter,
) http.Handler

New inits an http handler for the full RPC api.

func Provide

func Provide[RO, RW any](name string) fx.Option

Provide the package components for the DI container.

func ProvideEntTransactors

func ProvideEntTransactors[TX EntModelTx, MC EntModelClient[TX]]() fx.Option

ProvideEntTransactors provides the RO transactor.

func ProvidePgxTransactors

func ProvidePgxTransactors() fx.Option

ProvidePgxTransactors provides transactors for pgx transactions.

func TestProvide

func TestProvide[RO, RW, ROC, ROW any](name string) fx.Option

TestProvide provides dependencies for testing.

func WithIdentity

func WithIdentity(ctx context.Context, tok openid.Token) context.Context

WithIdentity returns a context with the openid token.

Types

type Auth

type Auth struct {
	connect.Interceptor
	// contains filtered or unexported fields
}

Auth provides authn and authz as an injector.

func NewAuth

func NewAuth(cfg Config, logs *zap.Logger, authn *clauthn.Authn, authz *clauthz.Authz) (lgr *Auth, err error)

NewAuth inits the logger.

type AuthzInput

type AuthzInput struct {
	// Input from the process environment
	Env map[string]any `json:"env"`
	// OpenID token as claims
	Claims openid.Token `json:"claims"`
	// Procedure encodes the full RPC procedure name. e.g: /acme.foo.v1.FooService/Bar
	Procedure string `json:"procedure"`
}

AuthzInput encodes the full input into the authorization (AuthZ) policy system OPA. It should provide ALL data required to make authorization decisions. It should be fully serializable to JSON.

type Config

type Config struct {
	// disables stack trace information in error details
	DisableStackTraceErrorDetails bool `env:"DISABLE_STACK_TRACE_ERROR_DETAILS"`
	// allows configuring the 'env' input field send to the policy, allows for configuring input
	// invariant to the environment
	AuthzPolicyEnvInput string `env:"AUTHZ_POLICY_ENV_INPUT,expand" envDefault:"{}"`
}

Config configures the components.

type ConstructClient

type ConstructClient[SC any] func(httpClient connect.HTTPClient, baseURL string, opts ...connect.ClientOption) SC

ConstructClient is a funct signature that constructs a client.

type ConstructHandler

type ConstructHandler[SH any] func(svc SH, opts ...connect.HandlerOption) (string, http.Handler)

ConstructHandler defines the type for constructing a connectrpc service handler.

type EntModelClient

type EntModelClient[TX EntModelTx] interface {
	BeginTx(ctx context.Context, opts *entsql.TxOptions) (TX, error)
}

EntModelClient is a generic type to constraint the model client to those generated by Ent.

type EntModelTx

type EntModelTx interface {
	Commit() error
	Rollback() error
}

EntModelTx is a generic type to constraint the tx to those generated by Ent.

type EntROTransactor

type EntROTransactor[TX EntModelTx, MC EntModelClient[TX]] struct {
	connect.Interceptor
	// contains filtered or unexported fields
}

EntROTransactor provides an ent tx to the context.

func NewEntROTransactor

func NewEntROTransactor[TX EntModelTx, MC EntModelClient[TX]](logs *zap.Logger, mc MC) *EntROTransactor[TX, MC]

NewEntROTransactor its a RO transactor for the model client type.

type EntRWTransactor

type EntRWTransactor[TX EntModelTx, MC EntModelClient[TX]] struct {
	connect.Interceptor
	// contains filtered or unexported fields
}

EntRWTransactor provides an ent tx to the context.

func NewEntRWTransactor

func NewEntRWTransactor[TX EntModelTx, MC EntModelClient[TX]](logs *zap.Logger, mc MC) *EntRWTransactor[TX, MC]

NewEntRWTransactor its a RW transactor for the model client type.

type Logger

type Logger struct {
	connect.Interceptor
	// contains filtered or unexported fields
}

Logger logs RPC calls as an interceptor.

func NewLogger
