Installation

Install @wyrly/core first. Add framework adapters only when your app needs them.

Deno 2.x

Use JSR for Deno projects.

deno add jsr:@wyrly/core

Then import from @wyrly/core.

import { createContainer, Injectable, token } from "@wyrly/core";

Node.js 20+

Use npm for Node.js and bundler-based applications.

npm install @wyrly/core

import { createContainer, Injectable, token } from "@wyrly/core";

Bun

Use the npm package from Bun.

bun add @wyrly/core

import { createContainer, Injectable, token } from "@wyrly/core";

Framework adapters

Install the adapter that matches your runtime.

Runtime	Package
Next.js App Router	`@wyrly/next`
Express	`@wyrly/express`
Hono	`@wyrly/hono`
Fresh 2.x	`@wyrly/fresh`
GraphQL request context (low-level)	`@wyrly/graphql`
Fastify 5	`@wyrly/fastify`
GraphQL Yoga 5	`@wyrly/yoga`
Apollo Server 4+	`@wyrly/apollo`

Use @wyrly/graphql when you build GraphQL context yourself. For Yoga or Apollo Server integration, install @wyrly/yoga or @wyrly/apollo instead — see Framework adapters. For example, install the Next.js adapter with:

npm install @wyrly/next @wyrly/core
