@wyrly/yoga

Request-scoped dependency injection for GraphQL Yoga 5 without reflect-metadata — use yogaDIPlugin() and yogaContext() for one scope per GraphQL request.

Japanese: README.ja.md

Install

npm install @wyrly/yoga @wyrly/graphql @wyrly/core graphql-yoga

Peer dependency: graphql-yoga ^5.0.0.

Requirements

• Everything required by @wyrly/core and @wyrly/graphql
• GraphQL Yoga 5.x

Quick start

import { createSchema, createYoga } from "graphql-yoga";
import { yogaContext, yogaDIPlugin, type YogaServerContext } from "@wyrly/yoga";
import { createContainer } from "@wyrly/core";

const container = createContainer();

const yoga = createYoga<YogaServerContext>({
  schema: createSchema({ typeDefs, resolvers }),
  plugins: [yogaDIPlugin(container, {
    configureScope(scope) {
      // map request → port tokens (e.g. CurrentUserToken)
    },
  })],
  context: yogaContext,
});

Resolvers use ctx.wyrly.di.resolve(...). The plugin disposes the scope on onResponse.
