npm install -g strongloop
cd affiliate-api

Basic tutorial

create model

slc loopback:model

Compose your API, run, deploy, profile, and monitor it with Arc

slc arc

Run the app

node .
> Web server listening at: http://0.0.0.0:3000
> Browse your REST API at http://0.0.0.0:3000/explorer

Routing

LoopBack middleware chainではexpressのroutingを含んでいる

Express　routingのサマリ

以下はexpressのroutingのkey point

• Routing refers to the rules for capturing requests to the server, and the subsequent passing through and handling of requests through a chain of middleware functions.
  • Routingはserverへのrequestを捕らえ、middleware functionsへの続いての通過と、requestのhandlingをする。
• A middleware function accepts three objects, the request object (req), the response object (res), and the next middleware in the chain (next); in that order.
  • middleare functionは3つのobjectを受け取る、request, responseそして、次のmiddlewareのchain
• You load middleware either using app.use() or by assigning it as the callback function of a route definition.
• Multiple middleware can be matched to handle the requests to a route, these matched middleware make up the middleware chain for the request. The request will pass through each middleware in the order they were loaded, unless one of the middleware in the chain terminates the propagation.
• Any middleware in the chain may terminate the request propagation by sending a response back to the client.
• A middleware can send the response to the request using one of the response methods in the response object or pass on the request to the next middleware by calling next().
• If a middleware sends the server response, conventionally the request does not propagate further in the middleware chain. Any call to next() will likely result in an error.
• A middleware function can also take four arguments. In this case, it is an error handling middleware. The parameters to the function in their order are: the error object (err), the request object (req), the response object (res), and the next middleware in the chain (next).

// expressでnextを使う例
app.get('/example/b', function (req, res, next) {
  console.log('response will be sent by the next function ...');
  next();
}, function (req, res) {
  res.send('Hello from B!');
});
