Hey Lucky. Welcome to Node!
I'm not sure what language you were using before trying JavaScript but one
thing I want to mention is that JavaScript is very much non-opinionated. It
doesn't matter if you want to use a functional design paradigm or an object
oriented paradigm. The reason I mention this is because how you solve this
problem will probably depend on how you want to design your applications. I
personally prefer OOP so I will start with solving this problem that way.
To start lets create a class for your request and export it so you can use
it elsewhere.
SomeRequest.js
module.exports = class SomeRequest {
constructor (requestObj) {
this.uuid = requestObj.id
this.username = requestObj.name
}
}
Now to use this class you would do the following
someOtherFile.js
const SomeRequest = require('./SomeRequest.js')
const request = new SomeRequest(originalRequest)
The request object should be converted as you like and is ready to use. As
someone from a Java shop this makes the most sense to some of my coworkers
since it looks more like what they are used to.
Now if you want to do it functionally like you are I wouldn't bother using
a JSON templater. It's another dependency that you don't control and I
don't think it does enough to justify it's use. Instead I would try
something like the following.
convertSomeRequest.js
module.exports = (requestObj) => {
return {
uuid: requestObj.id,
username: requestObj.name
}
}
And to use it in another file...
const convertSomeRequest = require('./convertSomeRequest.js')
const request = convertSomeRequest(originalRequest)
One last thing. Looking at this post it seems you are trying to work with
raw JSON all the time. It's easier to work with data if you are dealing
with an actual object vs a string. If your using a framework like express
or koa then the JSON should automatically be converted to an object and
then back to JSON when you respond. If not you will need to convert the
responses yourself. Javascript has a nice JSON library built in to deal
with this.
JSON.stringify(object) // converts an object to a JSON string.
JSON.parse(jsonString) // converts a JSON formatted string into an object.
This should make things easier to work with for you.
