Curveball Router
This package is a simple router for Curveball.
Installation
npm install @curveball/routerGetting started
The simplest, and recommended form works as follows:
import { Application } from '@curveball/kernel';
import router from '@curveball/router';
const app = Application();
app.use(
router('/foo/:id', ctx => {
// the 'id' is available via ctx.params.id
})
);It's also possible to do per-method routing, using the following syntax.
import { Application } from '@curveball/kernel';
import router from '@curveball/router';
const app = Application();
app.use(
router('/foo/:id')
.get( ctx => { /* GET requests */ })
.post( ctx => { /* POST requests */ })
);You can either specify 1, or multiple middlewares. The following example runs 2 fictional middlewares on a route.
const app = Application();
const route = router(
'/foo/:id',
myAuthMiddleware,
myBodyparser,
ctx => {
ctx.response.body = 'success!';
}
);
app.use(route);Access matched route in other middleware
The matched route is added into the Curveball context for other middleware to access if they need (such as for access request logging). It will be accessible after the router has executed.
import { Application, Context } from '@curveball/kernel';
import router from '@curveball/router';
const app = Application();
app.use(async (ctx: Context, next) => {
await next();
// Will be '/foo/:id'
const matchedRoute = ctx.router?.matchedRoute;
});
app.use(
router('/foo/:id', ctx => {
ctx.response.body = '/foo/' + ctx.state.params.id;
});
);
