Using REST and GraphQL in different parts of a single web app - javascript

I'm creating a web app and I'm wondering if it's possible to create it using both REST and GraphQl. I don't mean I wan't to wrap REST in graphql. It is a web app with a variety of functionalities and graphql would be best suited towards the blog portion of the app but we've already constructed the rest of it using REST. Would it be possible/bad practice to use them for the respective parts of the app?

I don't see any problem with that. Just make sure to create a single API abstraction that would internally handle both cases so that the app itself is not concerned about that (in case you'll want to go all-in with GraphQL at some point).

Using AngularJS for Multiple Page Application [duplicate]

We are looking at options to build the front end of an application we are creating and are trying to evaluate a tool that will work for us and give us the best platform to move forward.
This is a Node.js project. Our initial plan was to use Express and go down that route, but we decided that before we kick off this stage it might be best to review what is out there. Our application has several areas which we don't believe fit the single-page model in that they are related from an application perspective, but not from a view one.
We have seen a few of the frameworks we could use to build out the client like Backbone.js, Meteor, etc. and also AngularJS.
This may be a fairly obvious question, but we cannot seem to decipher if AngularJS is purely for single-page application or it can be used for multi-page applications like Express for instance.
UPDATE 17 July 2013
Just to keep people in the loop, I will be updating this question as we go through the process. We are going to build everything together for now, and we will see how well that performs. We have reached out to a few people who are more qualified with AngularJS than us and posed the question regarding splitting up larger applications that share context, but may be too large working on a single page.
The consensus was that we could serve multiple static pages and create AngularJS applications that work with only those pages, effectively creating a collection of SPA and linking those applications together using standard linking. Now our use case is very specific as our solution has several applications, and as I said we are going to try the single code base first and optimise from there.
UPDATE 18 June 2016 The project fell of a cliff, so we never got round to getting too much done. We have picked it up again recently, but are no longer using angular and are using React instead. We are still using the architecture outlined in the previous update, where we use express and self contain apps, so for example, we have a /chat route in express that serves up our React chat app, we have another route /projects that serves up the projects app and so on. The way we are kinda looking at it is each app is an aggregate root in terms of its feature set, it needs to be able to standalone for it to be considered an app in itself. Technically, all the information is out there, its just basic express and whatever flavour of client side app building goodness you want to use.
Not at all. You can use Angular to build a variety of apps. Client-side routing is just a small piece of that.
You have a large list of features that will benefit you outside of client-side routing:
two-way binding
templating
currency formatting
pluralization
reusable controls
RESTful api handling
AJAX handling
modularization
dependency injection
It's crazy to think that all of that "could only be used in a single page app". Of course not.. that's like saying "Jquery is only for projects with animations".
If it fits your project, use it.
I struggled with the "how" at first with Angular as well. Then one day it dawned on me: "It is STILL javascript". There are a bunch of examples on the ins-and-outs of Angular (one of my favorites along with the book https://github.com/angular-app/angular-app). The biggest thing to remember is to load in the js files just like you would in any other project. All you have to do is make sure the different pages reference the correct Angular object (controller, view, etc.) and you are off and running. I hope this makes sense, but the answer was so simple I overlooked it.
Maybe my experience will be useful to someone. We split our project logically. One SPA we use for feed, another one to work with the map, another one for editing a user profile and etc. For example we have three apps: feed, user and map. I use it in the separated urls, like this:
https://host/feed/#/top/
https://host/user/#/edit/1/
https://host/map/favorites/#/add/
Each of these applications has it's own local routing mappings between states in the application.
I think it is a good practice because each application work only with its own context and load dependencies that it really need. Also, it's practice very good for debug and integration processes.
Indeed, you can very easily make a mix of SPA apps, for example the feed will be url with the angularjs application, the user app with the reactjs and map to the backbone.js application.
In response to your question:
Angular not just for SPAs, Angular play good and fast for SPA applications, but no one bothers to build MPA application of a variety of SPA applications. But thinking about your url architecture don`t forget about SEO availability of your applications.
I also support the idea:
What’s the difference between a project and an app? An app is a Web
application that does something – e.g., a Weblog system, a database of
public records or a simple poll app. A project is a collection of
configuration and apps for a particular website. A project can contain
multiple apps. An app can be in multiple projects.
If all you need is a few pages with client databinding, I'd go with Knockout and Javascript Namespacing.
Knockout is great, especially if you need uncomplicated backward compatibility and have fairly straight forward pages. If you're using 3rd party components, Knockout's custom bindings are straightforward and easy to work with.
Javascript namespacing allows you to keep your code separate and manageable.
var myCo = myCo || {};
myCo.page = {
init: function(){ ... },
...
}
And in a script tag after your other scripts are loaded
<script>
myCo.init();
</script>
The key is, you use whatever tool you want for when you need it. Need databinding? Knockout (or whatever you like). Need routing? sammy.js (or whatever you like).
Client code can be as simple or complicated as you want it. I tried integrating Angular into a very complicated site with an existing proprietary framework, and it was a nightmare. Angular is great if you're starting fresh, but it has a learning curve and locks you into a very tight workflow. If you don't follow it, your code can get really tangled really fast.
I'd say Angular is overkill if you're just looking to develop a SPA. Sure, if you're already comfortable developing with it, go ahead. But if you're new to the framework and only need to develop a SPA, I'd go with something more simple with a number of its own perks. I recommend looking into Vue.js or Aurelia.io.
Vue.js uses two-way data binding, MVVM, reusable components, simple and quick to pickup, less code to write, etc. It combines some of the best features of Angular and React.
Aurelia.io, in all honesty, I don't know much about. But I've peeked around and it seems an alternative worth looking into, similar to the above.

Laravel + ReactJS loose components in blade views. A good practice?

The following is unclear to me. So far, I don't see lose Reactjs components embedded in views, but only in Single Page Applications.
I was wondering if one could use Reactjs in a Laravel application in combination with the blade template engine? I have a Laravel project and I like the way ReactJS binds to the DOM. But I do not need an entire JS SPA.
So is it possible AND a good practice to use different ReactJs components loosely in blade views? For example a React table component and a header message component, that also are able to communicate with each other.
There is a package that does just that.
However I would argue it would be a better practice if you separate the front-end and back-end completely. So you can use Laravel to serve the data using REST API endpoints and then display everything using a React app.
This way they will be loosely coupled and if you ever want to swap out one for the other (e.g. swap out React for Angular) then it would be a lot easier as your api endpoints wouldn't have to change at all.
EDIT: Some benefits of a headless CMS (taken from pantheon.io):
By shifting responsibility for the user experience completely into the
browser, the headless model provides a number of benefits:
Value: future-proof your website implementation, lets you
redesign the site without re-implementing the CMS
Sets frontend developers free from
the conventions and structures of the backend. Headless development
not only eliminates “div-itis”, it gives frontend specialists full
control over the user experience using their native tools.
Speeds up the site by shifting display logic to the client-side
and streamlining the backend. An application focused on delivering
content can be much more responsive than one that assembles completely
formatted responses based on complex rules. Builds true
interactive experiences for users by using your website to power fully
functional in-browser applications. The backend becomes the system of
record and “state machine”, but back-and-forth interaction happens
real-time in the browser.
Lets say you also want to build a mobile app using React Native that would use the same underlying code base as your React web app. If you have a decoupled CMS, so your backend is only serving data then you can make calls to this same backend from both your web app and mobile app without worrying about content types, response formats etc... In-fact, with React Native you can use the same React codebase for the mobile app along with the web app and you would only have to change some views around.
It's a great way to re-use your code with better modularity and seperation of concerns.

Hapi.js, Bookshelf.js and a real world example

I've been experimenting with Hapi.js recently and although it's a great framework there doesn't seem to be any real-world examples that are of any use.
One thing missing is the best way to load Models / Collections within Hapi (and node in general to be fair).
Is there any recommended best way of loading these with Hapi?
I'm currently separating all my route logic into plugins and I'm simply creating the Models and Collections within that plugin. I then use plugin.method('Models.MyModel', Model); method to make the model available throughout the application. The is fine for a small application but as the app gets bigger I'd like to split thing out more so I can separate routing and storage from the business logic.
I've just started to make a Project using Hapi and Boostrap. You can check it here

Single-Page Play Application

I've just read about single-page web applications that expose a RESTful interface for retrieving the data - for example in JSON format, and that just provide a single HTML page referencing the Javascript file responsible for invoking the RESTful interface and building the web user interface dynamically in the client's web browser.
To implement this in Play, one should implement the controllers so that they return JSON instead of HTLM and implement some CoffeScript for rendering the user interface on the client side.
So far so good... but I'm wondering whether this design makes sense for large web applications since the amount of javascript code to be run on the client side would increase more and more.
My initial idea was to implement the web application using Play's template engine and then to provide a RESTful interface for Mobile apps.
Any suggestion, idea, or link to documentation that covers this topic would be really appreciated ;-)
The Play for Scala book has a chapter on this topic. They use a single view as an entry point, that's it.
As for large applications, that's a valid concern. For that you might want to use libraries such as RequireJS (which Play 2.1 has built-in support for), among others. You also might want to split your app into sub-modules to manage complexity. On the client side, you probably should use a framework, too, such as AngularJS.
Concerning Play there's not much left to say, it's a very good platform to expose RESTful JSON services. I recommend you take a look at the JSON documentation and also check out ReactiveMongo.
Providing a common REST API should work fine. At the moment I am working with a Play 2.0 server app for browser (Backbone etc) and iOS clients. The browser client is totally separate from the Play app and deployed independently.
I think there is some initial overhead compared to Play template approach but having just one set of controllers to test etc makes life easier.
Couple points to consider:
Client authentication. Preferably you would use the same way for all the clients.
At some point you might want to introduce some specialized REST API for one of the clients in order to save bandwith and number of requests. For example mobile landing screen is a typical candidate.
You need to document your REST APIs more detailed as the web client devs are not sharing the codebase.
