MICROSERVICE-RESTful-Nodejs

This is example for RESTful API that construc base on microservice with Node.js, this project are make from window then it may be problem with linux but it shold't have.

Microserive diagram overview

This backend code will let devoper to enjoin his business logic in control part only, for model and infra part are automate update. In control part are work as promise base then it will clean code.

example

   methods( get_data_from_redis )
          .then( result_from_redis => {
                 if( result_from_redis ) return result_from_redis
                 return methods( get_data_from_mysql)
          .then( result_from_mysql => {
                 if( !result_from_mysql ) return "there is no data"
                 return methods( save_data_redis )
          .then( result_from_redis => {
                 if( err ) return err
                 return result_from_mysql
          })
          .catch( err => err )
   }).catch( err => err )

Prerequire for test

• Docker && docker-compose
• Nodejs
• Postman for test

Installation step

1. get source code

   git clone https://github.com/tudtude/MICROSERVICE-RESTful-Nodejs.git
   

2. run command npm install for get all dependency code in each module folder( gateway, user, order, mysqlgw, redisgw )

   npm install
   

   Then you need to run 5 times, in eache folder

3. run command docker-compose up mysql in root part first for init mysql database avoid error, due with dev environtment it need to set up DB first

   docker-compose up mysql
   

   After Mysql was ready for accept TCP3306 then shut it down

   by press contol c 
   

4. run command docker-compose up in root part and everything should be ok ( redis server it quite fast then no need to do like Mysql)

   docker-compose up
   

5. In next time to run this project you can run docker-compose up, no need to run docker-compose up mysql again. Anyway, if you still found error from mysqlgw then just wait for 2-3 min and then put command line in another window as

   docker-compose restart mysqlgw
   

Test by postman

1. getbyID

   uri : localhost/api/user/getbyID/:id

   input: :id unmber

   output : object of user folowing id as we put

   example : localhost/api/user/getbyID/1

2. add

   uri : localhost/api/user/add/

   input: user object objbect ( x-wwww-form-urlencoded )

   output: string "user already add"

   example of user object
