(node-koajs-rest-skeleton v3.5.3
A simple Koajs 2.7.0 Application REST Skeleton
This version based on koa 2.7.0.
quick start
Checkout node-koajs-rest-skeleton:
$ git clone https://github.com/ria-com/node-koajs-rest-skeleton
Make your own new project:
$ mv node-koajs-rest-skeleton my_new_project
$ cd my_new_project
$ rm -rf .git
Edit package.json:
$ vi package.json
Edit config/ files:*
$ vi config/default.js
Install modules
$ npm install
Start app:
$ node ./index.js
testing
Make your own Spec-files for testing and start test
In this skeleton for automatic testing was used jasmine-nodie & Frisby (REST API testing framework).
I wrote several tests that you can use as examples.
All tests should be placed in the ./spec folder. The name of each test file must end with *Spec.js
To run the tests, use
$ cd my_new_project
$ npm test
Manual testing your REST service:
You can also manual check the serviceability of your service with bash and curl
get user id 1
$ curl -XGET "http://localhost:8081/users/1"
get all users
$ curl -XGET "http://localhost:8081/users"
add new user
$ curl -XPOST "http://localhost:8081/users" -d '{"name":"New record 1"}' -H 'Content-Type: application/json'
edit user id 3
$ curl -XPUT "http://localhost:8081/users/3" -d '{"name":"New record 3"}' -H 'Content-Type: application/json'
delete user id 3
$ curl -XDELETE "http://localhost:8081/users/3"
console api
Usage: /usr/bin/node ./console.js --section [string] [--action [string]] [--opt [object]]
Options:
--opt, --options example --opt.app=mobile --opt.s=1 [default: {}]
--section [required]
--action [default: "index"]
For example
$ ./console.js --section=default --opt.hello=world
Hello world defaultController & index action with options: {"hello":"world"}
rabbitmq api
Usage: NODE_WORKER_NAME=[worker_name] NODE_QUEUE_NAME=[queue_name] /usr/bin/node --harmony ./worker.js
For example
$ NODE_WORKER_NAME=example NODE_QUEUE_NAME=example /usr/bin/node --harmony ./worker.js
kubernetes api
Several new features have been added that can be used in conjunction with kubernetes
-
Auto shutdown. Set the environment variable NODE_LIFE_TIME to specify
the time at which the service will suspend its work, for exsmple:
NODE_LIFE_TIME=24h или NODE_LIFE_TIME=30mIf the variable is not set, then "Auto shutdown" is disabled
-
Redy state. Your app can tell the kubernetes system that it
is temporarily not ready to accept new requests. How to do this is
described in the example belowconst {setReady} = require('../controllers/kubernetesController'); // ... // setReady(false) // to temporary disable new requests // ... // setReady(true) // to restore accept new requestsThis should be configured in the config of kubernetes pod,
the address on which poll is created: /redyz -
Health state. Your app can tell the kubernetes system that it
is temporarry broken. How to do this is described in the example belowconst {setHealth} = require('../controllers/kubernetesController'); // ... // setHealth(false) // to tell kubernetes: "app is broken" // ... // setHealth(true) // to tell kubernetes: "app is live"This should be configured in the config of kubernetes pod,
the address on which poll is created: /healthz
In order to avoid cluttering the minimal code of our REST-service, additional
functionality will be available when running the app via index.kubernetes.js:
$ node ./index.kubernetes.js
