koa-66

library1.0.1jsnpmunverified

Router middleware for Koa v2 that supports Express-like HTTP verb methods (get, post, put, delete, all), param middleware, automatic OPTIONS/HEAD responses, 501/405 status codes with headers, and a plugin system for injecting middleware via config objects. It allows mounting routers on paths, supports multiple middleware as arguments or arrays, and can throw errors with status codes. Version 1.0.1 is the latest stable release, targeting Node >= 4. Alternatives like koa-router are more actively maintained.

Verified usage

Router

✓ const Router = require('koa-66')

✗ import Router from 'koa-66'

Package uses CommonJS and has no default ESM export; require() is required for version 1.x.

Router (as named export)

✓ const { Router } = require('koa-66')

✗ const koa66 = require('koa-66'); const Router = koa66.default

Router is exported as module.exports = Router, so destructuring works the same as importing the whole module.

Router (constructor)

✓ const router = new Router()

✗ const router = Router()

Router must be instantiated with new; calling without new will throw an error.

Creates a basic Koa app with a single GET route using koa-66 router.

const Koa = require('koa'); const Router = require('koa-66'); const app = new Koa(); const router = new Router(); router.get('/', async (ctx) => { ctx.body = 'Hello World!'; }); app.use(router.routes()); app.listen(3000); // Visit http://localhost:3000/ => Hello World!

Debug

Known issues

gotchaRouter must be instantiated with `new`.

fix

Use `new Router()` instead of `Router()`.

affects: >=1.0.0

deprecatedThe package has not been updated since 2016 and relies on Node >= 4. It may not be compatible with modern Koa v2 releases.

fix

Consider using koa-router or @koa/router which are actively maintained.

affects: >=1.0.0

gotchaNo ESM support; only CommonJS require() works.

fix

Use `const Router = require('koa-66')` instead of `import Router from 'koa-66'`.

affects: >=1.0.0

breakingThe `mount` method expects a path and a sub-router; passing incorrect arguments may cause silent failures.

fix

Ensure `router.mount('/prefix', subRouter)` is used correctly.

affects: >=1.0.0

gotchaPlugin middleware uses `ctx.state.plugins` which may conflict with other Koa middleware.

fix

Check that no other middleware sets ctx.state.plugins before using plugins.

affects: >=1.0.0

Errors

Common errors & fixes

Router is not a constructor

Calling `Router()` without `new` when the package exports the constructor directly.

fix

Use `new Router()` instead of `Router()`.

require(...) is not a function

Attempting to use `require('koa-66')` as a function (e.g., `require('koa-66')()`) instead of instantiating with new.

fix

Use `const Router = require('koa-66'); const router = new Router();`

Cannot find module 'koa-66'

Package not installed or missing from node_modules.

fix

Run `npm install koa-66` to install the package.

router.routes is not a function

Variable `router` is not an instance of Router (e.g., it's the require() result).

fix

Ensure you create a new Router instance: `const router = new (require('koa-66'))()`
