Does it make sense to develop a rest service with node.js backed with mongodb? Is there a framework to make this easy like express?
Thanks.
Why can't you use express? It implements all CRUD methods through:
app.get(...);
app.post(...);
app.put(...);
app.del(...);
In these function calls you can handle your mongodb queries and send JSON objects back to the client, if appropriate.
I hope I could help! :)
Like graydsl said express allready supports these verbs. To parse JSON you would just use JSON.parse and to stringify you would use JSON.stringify. I would use Mongoose to talk to mongodb. Also to help you write clean code I would practice TDD/BDD using mocha. Finally I think you should have a look at underscore, async and superagent.

Is there any example code implementing GraphQL on NodeJS without using any other middleware like Express, Apollo, etc. Just pure NodeJS http server with GraphQL, and any SQL db.
upd: If someone interested, you can check out my implementation on github - pureGraphQLapi
Nothing prevents you from using Node.js and GraphQL only ; you will be writing a little more code though.
Create your HTTP Server with Node.js only
Listen to incoming requests and use POST json body (for example) to pass query and variables to graphql function
I have a simple REST API written in Golang. Now I want to have an async UI and wanted to go with ReactJS + Babel or Typescript + fetch() to get data from my JSON api. Don't want nodejs or anything else.
Most of the examples require nodejs and I can't find something to have as an example to build the UI. Could someone help with an example?
Figured it out finally.
Basically using babel-standalone helped a lot. And using axios for fetching data was easy enough.
I would like to return localized Strings for multilanguage business objects in our RestFul API based on node.js, restify and mongoose. I have the requirement to store the translated resources on our translation resource server, but also need to support dynamic creation of those business objects.
I found a solution to easily plugin the i18n process in the POST/PUT calls using a single pre-'save' mongoose middleware on all Schema, when creating or updating my multi-languate business objects - this works because I am able to pass the request context to the obj.save(req, callback) call.
But, I am struggling to plug in the i18n on simple GETs. I thought of and tried different ways where I can plugin the i18n before returning the response, but don't really find a good way. Options I thought of:
translate in a mongoose middleware pre /post ('init'):
Problem: I don't have access to the request context, and therefore
don't know the locale to return, so I cannot translate there.
translate in the toObject() / toJSON {transform: }:
Same issue - i don't have the request context in these hooks.
translate in the handler/controller methods for each ressource.
Problem: Duplication, I have to do it everywhere, I would really prefer a solution I can define on the model/Schema layer
translate in a restify / express middleware towards the end:
Problem: I don't have access to the mongoose schema metainformation anymore, so I don't know which attriutes to translate.
Edit: just found this additional way:
- translate in a custom restify responseFormatter:
This seems to work nicely, in the reponseformatter I have access to everything I need. It kind of seems a little weird from an architechtural point of view, but if nobody has a better idea, I will add this as an answer.
Maybe (hopefully) I am missing something obvious...
thanks for any hints
I'm working with expressjs and socket.io in nodejs. I'm looking into assign identical route handlers to requests made in either HTTP or via websockets/socket.io.
For instance:
var responder = function(req, res){
req.params //<-- {id: 'something...'}
}
app.get('/foo/:id', responder);
io.on('/foo/:id', responder);
socket.io doesn't appear to have this type of routing functionality. Does anyone know of a library/module to help with this?
There are several options.
If you'd like to keep using express, check out express.io.
If you don't mind using something a bit different, sails lets you do this sort of thing as well.
(Update: sails now uses express too)
Both have been used in production successfully.
Note that routing is also pretty simple to implement on your own. If you check out how express do it I'm sure you'll be able to figure out a slim implementation that would match you needs.
Good luck! Let me know what you ended up using and how it worked for you.
I am trying to build a test app for learning Node.js. I came from wordpress background and Apache has setup most of backend logics for me. But now, I have to build my own. I have a question about how to serve JSON files from server side to client side. What is the workflow -- Backbone.js handle all client side Data manipulation, send/save/get/fetch from couchDB, serve JSON object from NODE.js backend?
I am using Express Microframework for building HTTP server, installed the Cradle middleware for access CouchDB NoSQL database. I successfully posted the data from Client side HTML (Jade template engine) to the CouchDB Database/Document and able to retrieve those data back from Server through Cradle middleware. Things work out great. But it was all done by Backend.
I want to use Backbone.js for my client side Javascript. Backbone.js is looking for JSON object which send back from the HTTP server. Cradle Middleware is able to create JSON object but only send them directly to the Jade Template, I could use Jade syntax for loop to iterate over the data object but it still not meet what I want for Backbone.js handle all the data entry. I realize that I need to get JSON obj via ajax ( either a file generated by HTTP then send back to the client OR send straight object to the client ). Cradle Middleware could not do that.
I did more research on this questions. I tried CouchApp, it does what I need. Using the Backbone.js to handling all the data, send/save/fetch data from CouchDB database. But it is a running in CouchApp, it is not an Express Node.js workflow. ( Maybe I am wrong or just do not how it work )
I tried backbone-couchdb.js. I read through the Details and still do not know it is going to help me to get what I want. ( Maybe need more tutorial or code example ). I am still thinking that I need a Backbone CouchDB driver to connect those two and somehow serving them by NODE.js backend.
Is there anybody who could tell me about how JSON file is being served by Node.js, how backbone.js interact with data save/fetch/get from CouchDB? What is the best practice / workflow? Other good resources, code examples, useful tools?

This is incorrect. You can just send the json back without rendering a template.
function(req, res, next){
db.view('user/byUsername', { key: 'luke' }, function (err, doc) {
res.send(doc); // or res.json(doc);
});
}
