Installation

Install Wyrly DI for Deno, Node.js, Bun, and supported web frameworks.

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	@wyrly/graphql

For example, install the Next.js adapter with:

npm install @wyrly/next @wyrly/core
