Usage

Check samples for usage.

API

Xeno

Create an app instance.

const app = new Xeno(options);

options

{
  errorHandler: async (err, ctx) => {} // async function that will be called when any error occurs
}

app.addRoute(options):

Add a route to the application.

options

{
  method: 'post', // defaults to get when not provided
  url :'test/:testId', // suppports `/static`, `/dynamic/:param`, `/wildcard*`
  handler: async (ctx) => {}, // optional async handler function executed on route
  some: 'route metadata', // arbitrary metadata to add to `ctx.req.route`
  other: 'property',
}

app.addHook(hook, handler)

Add a hook to be executed at different phases of request.

hook : String // onRequest, onParse, onRoute, onSend, onResponse
handler : async (ctx) => {} // async function

app.start(<http(s) module>, <http(s) opts>, port, callback)

Start the server.

Handler signature

Handlers (route and hook) are called with a ctx object.

ctx:

ctx = {
  req: {
    raw: <Raw NodeJS request>,
    method: String, // request method
    originalUrl: String, // request url (path + query string)
    url | uri: String, // path component

    search: String, // ?query=string
    query: Object, // querystring as object
    params: Object, // dynamic path params
    headers: Object, // request headers

    rawBody = [Buffer | String],
    body: Any,

    route: { // metadata about the current route
      method: String,
      path: String,
      *: Any,
    }
  },
  res: {
    status(Number), // set reponse status code
    header(String, String), // get or set response header name and value
    headers(Object), // get all or set multiple response headers
    removeHeader(String), // remove a response header
    body: [Object | String | Buffer | Stream], // set response body
  },
}
