A simple HTTP router with middleware support 👌
Everything within the router is treated as a middleware, the .get() and .post() methods just wrap the provided function
in another, special middleware that only allows requests of that kind.
The middlewares will run in registration order.
const port = 1337;
const host = '127.0.0.1';
const server = new Server();
// starting the server will return it's url and port, e.g. http://127.0.0.1:1337/
const serverUrl = await server.start(port, host);
// this middleware will run for each route
server.use('/', async (ctx, next) => {
if(Math.random() < 0.5) {
await next();
// manipulate the response after it's been processed!
ctx.res += ' And even more of them.'
} else {
ctx.status = 401;
ctx.res = 'You cannot access them kitties, sorry!';
}
});
server.get('/cats', async ctx => {
ctx.res = 'Imagine some cute cats here.';
});
// now, GET /cats and if you're not rejected you'll see:
// Imagine some cute cats here. And even more of them.The router allows for a really great middleware composition, which is done by sacrificing some performance. The performance could be improved by dropping the route stack and replacing it with a nested dictionary.
