dc-router

Another router for Koa(v2), base on decorator.

Current implementation is based on the older decorator proposal, please use babel-plugin-transform-decorators-legacy to compile codes. When new proposal is ready, dc-router will update immediately.

Usage

import koa from 'koa';
import {router, get, post} from 'dc-router';
 
let app = new koa();
 
@router('/product')
class Product {
 
    @get('/')
    index(ctx) {
        // Do something for GET /product
        ...
    }
 
    @get('/:id')
    query(ctx, params) {
        // Do something for GET /product/:id
        ...
    }
 
    @post('/:id')
    add(ctx, params) {
        // Do something for POST /product/:id
        ...
    }
 
}
 
app.use(Product);
app.listen(80);

Decorate a function ?

Current proposal don't support decorator for function, because it's not compatible with function declarations being hoisted, more information see this: https://esdiscuss.org/topic/decorators-for-functions

But if really want use dc-router for function, it could be this way:

function handler(ctx, params) {
    ...
}
 
// Don't need `router`
// Just `action`
app.use(get('/hello')(handler));
