⁠Editor Microservice

This is an end microservice application giving the functionality of online text editor with four basic functions,

• Saving the written part
• Persisting the saved part after consecutive saves
• Publishing the articles for feeds
• Sending the published article to search microservice

There will be two collection "SavedDoc" and "PublishedDoc" in our "Docs" Mongodb Database.

##Prerequisites:

• Docker-engine
• Mongodb Docker Container
• Elasticsearch/Solr Node.js Application (Optional)

##Build-up Start Docker Engine and Mongo Container, Run docker build --name <username>/editor-service /path/to/editor-service's/Dokerfile in your terminal and then, docker run -it --link mongo:db <username>/editor-services bash This service will work on port 8080.

##API This microservice can be deployed for adding an editor to any application by using simple HTTP RESTful API calls, by using GET localhost:8080/editor we can get an editor. By POST localhost:8080/editor we initiate a process of saving or publishing an article, if we have populated our form response body with saved, means req.body.save it will save the article or req.body.publish then it will publish it. The JSON format for the documents will be,

mongoose.model({
  _id:String,
  title:String,
  shortScript:Script,
  content:String});

Then for calling any saved or published article, we just need to call GET localhost:8080/saved/:<article ID> or GET localhost:8080/published/:<article ID> respectively.

After publishing the article this service also makes published article data available to any search microservice⁠ for indexing. This snippet should be added to published document callback

search(doc,function(data){
  logger.info('Elasticsearch returned'+data);
});

It will call the code below to send whole article to search microservice in JSON format,

//========./search/search.js
var http=require('http');
var querystring=require('querystring');
var chunk;

module.exports=function(matter,callback){
    var paper=querystring.stringify(matter);
    var options={
        hostname:'search',
        method:'POST',
        port:9200,
        path:'/index',
        headers:{
            'Content-Type':'application/x-www-form-urlencoded',
            'Content-Length':'doc.length'
        }
    };
    http.request(options,function(req,res){
        req.write(paper);
        req.end();
        res.on('data',function(data){
            chunk+=data;
        });
        res.on('end',function(){
            callback(chunk);
        });
    });
};
