Re-use POST and GET methods in Express - mongodb

Question

I'm building a CMS where I have to do a lot of POST and GET requests to my MongoDB. The problem I am having now is that, the more I work on my CMS, the more POST and GET requests I have to do and eventually a lot of double code I'm having in my application. My question is, can I somehow re-use the POST and GET methods? I am using Express framework, MongoDB and Angular on the Front-End.
Here is an example how my application looks like:
Express:
router.post('/news_blocks', function(req, res, next){
var randomNumber = Math.floor(1000 + Math.random() * 9000);
var news_image = req.files.myImage;
news_image.mv('/home//projects/website/public/uploads/' + 'image_' + randomNumber + '.jpg' , function(err) {
if(err){
console.log(err);
}else{
var data = new news_blocks(postOptions(req, randomNumber));
saveToDB(data,res);
}
});
});
router.post('/research', function(req, res, next){
var randomNumber = Math.floor(1000 + Math.random() * 9000);
var research_image = req.files.myImage;
research_image.mv('/home/projects/website/public/uploads/' + 'image_' + randomNumber + '.jpg' , function(err) {
if(err){
console.log(err);
}else{
var data = new research_blocks(postOptions(req, randomNumber));
saveToDB(data,res);
}
});
});
postOptions = function(req, randomNumber){
var options = {
title: req.body.title,
date: new Date,
message: req.body.message,
image: 'image_' + randomNumber
};
return options;
};
MongoDB model:
file1:
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var research_block = new mongoose.Schema({
title: String,
date: String,
message: String,
image: String
}, {collection: 'research'});
module.exports = mongoose.model("research", research_block);
File 2:
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var news_block = new mongoose.Schema({
title: String,
date: String,
message: String,
image: String
}, {collection: 'news'});
module.exports = mongoose.model("news", news_block);
As you can see, there is a lot of the same code in the POST methods. But I am not sure how I make this more DRY

Answer 1

Suggestion 1:
Make a controller file for every table. And, write functions in it to do all kind of operations in it. And, while calling a service send type of operation along with it. On basis of type you can call any function you want.
Suggestion 2:
Try using GraphQL
