Re: [nodejs] i heared a lot about nodejs but i am afraid

[Mark Hahn]

Node takes a bit of a learning curve but I personally think it is worth it.  When you start it will appear that you have to write a lot of code.  But when you learn what modules/extensions work for you it will get much easier.  

Of course there are certain types of apps where node should be used at any cost.  But for simple vanilla or MVC apps it is a matter of preference.

is there any risk involved as i dont want to regret in the end .

please guys advise should i invest in nodejs for such website ?

please guys advise should i invest in nodejs for such website ?

A few questions you might start out asking yourself:

1. How well do you know PHP/MySQL?
2. Have you built non-trivial apps with PHP, Ruby, etc. in the past?
3. Are you familiar with any PHP frameworks?
4. How comfortable are you with JavaScript?
5. Have you written any non-trivial apps with JavaScript? (i.e. client-side, MVC, etc.)

@ Wil Moore i am well versed with traditional MVC apps in php .but from new skill set point of view which has demand i was interested to do a professional app in nodejs but the point is would i able to develop  such site in nodejs without facing any critical errors  as i dont know  inner details of nodejs does nodejs supports  all features like php/mysql like for example

does it supports image thumbnail generation ? 

does it support pdf,excel ,csv file handlings
does it supports encryption /decryption algos lie AES,Rjinidial or RSA.

etc..... 

so main concern is does it have all the recipes required to develop a traditional or complex apps as i don't want to stuck at any point.

i have a  vps server with 256Ram is that enough for a site like ecommerce site developed with nodejs.

nodejs is a JavaScript runtime. Yes, you can do all those things in JavaScript. Whether there are existing modules that do those specific tasks I don't know. You can search on npm and find out:

https://npmjs.org

If no modules exist for specific tasks you need, you'll have to write the code yourself.

I suppose that depends on how popular the site will be, how many concurrent requests it will need to process.

> does it supports image thumbnail generation ?

YES
NodejsGD - https://github.com/taggon/node-gd
and you can use ImageMagick as well - I prefer this, GD I use for
image creation like captcha

> does it support pdf,excel ,csv file handlings

YES
on fast search about PDF - http://pdfkit.org/
EXCEL - its easy no matter of platform, i create EXCEL XML file and
its good to go
CSV - on fast search - https://github.com/koles/ya-csv - so it is supported

> does it supports encryption /decryption algos lie AES,Rjinidial or RSA.

YES
check out - http://nodejs.org/api/crypto.html - module

> etc.....
it depends but probably YES :)

> i have a vps server with 256Ram is that enough for a site like ecommerce

it depends

...but its not for traditional php my sql websites like a ecommerce website.

I wouldn't go that far. It (NodeJS) will be fine for such a site...possibly more ideal than the "traditional" tools.

i have to develop a product reviewing website i have option to choose between php/mysql or nodejs mysql .due to new uprising technology i am more inclined towards nodejs 

Given a choice, I wouldn't recommend that you go with PHP. This advice isn't based off of the countless "PHP Hate" articles (BTW, most of those articles are at least 90% accurate), but rather years of hands-on experience with the language/platform.

develop  such site in nodejs without facing any critical errors

JavaScript has a few well-known issues; but they are mostly minor. Many of the issues people run into with JavaScript are in the category of "It doesn't behave like C++/Java/PHP so it's wrong". When you have one of those moments, just remember: https://twitter.com/wilmoore/status/254686641795518465

as i dont know  inner details of nodejs does nodejs supports  all features like php/mysql like for example

Your major issues with NodeJS won't be NodeJS itself, but JavaScript. You'll want to put in the time to learn it well before doing anything too serious otherwise you'll end up with extremely messy code.

If you are well versed in automated testing, this is the platform for you. The NodeJS community tends to value automated testing at a much higher level than the larger in-general JavaScript community.

You will want to check out Mocha (Test Framework) and Chai (Assertion Library)

 

does it supports image thumbnail generation ? 

does it support pdf,excel ,csv file handlings
does it supports encryption /decryption algos lie AES,Rjinidial or RSA.

All of the above. When you are curious. visit npmjs.org and perform a package search. 

 

so main concern is does it have all the recipes required to develop a traditional or complex apps as i don't want to stuck at any point.

You will find an npm package for just about anything you need.

 

i have a  vps server with 256Ram is that enough for a site like ecommerce site developed with nodejs.

That won't get you too far with MySQL (or any relational database for that matter), but it should be fine for development purposes.

thanks  all of you guys i am really excited to see quite good response from nodejs community. actually my hosting provider has fixed 256MB RAM for one application mysql will be handled by other ram. so what do you think how much request nodejs can service in a month  in this ram? 

@WIL MILLER why dont you share your experience about how to actually do async compact & maintainable code in js

That will be fine initially.

Quick tips:

1 - Learn how to create modules asap.

2 - Test drive your code.

3 - Read this: https://github.com/rwldrn/idiomatic.js.

4 - Learn about constructors, prototype chain, and prototypal inheritance.

That should get you going.

A few random thoughts...

Unless you have specific inter-operability requirements, or something else, I would consider looking at different database solutions. Mongo melds nicely to JavaScript - natively dealing with json data transport (bson internally) and processing js functions internally. But there are also a plethora of lucene based solutions. There are SQL modules for node, but generally that isn't the best tool for the job.
Last time I looked there was no way of creating an xls file (I don't recall xlsx but since a good portion of the world is office <2010 its moot for me). You can make an rpc API or use a preexisting one (gearman comes to mind) and use the excellent perl module for this (and I hear there's a Ruby one as well).
There are no good classic MVC frameworks for node. You can define a single view with express and jump into middleware to pump out json, XML, binary, etc but you've got to try to keep things nice when you do this. There is also railway and a nodejitsu framework that look like they might be awesome in a year (but I'd dev with express at this point).
Node isn't as mature as PHP - its getting there quickly though. I never got into rails much, but it seems that node is moving much faster than rails ever did (in all aspects). Node development and adoption is surely moving faster than PHP ever did. My only worry is that people will get too comfortable with node and nosql DBs and forget basic security and make vulnerable sites which might give node bad press (I hope medeor has had improvements since I last looked - that scared me).
Don't write server side js like you write client side js. I use it because it removes one language or DSL from my app. But I can tell whether I'm looking at my server side code vs client side code from across the room (not sure if this makes sense to anyone else or if I'm not doing things correctly, but to me the code just looks different).
Since node is a standalone server, I think you'll notice a smaller footprint (than mod_php in Apache) though I'd still run production behind nginx (just because of mod_security, offloading static file server, and load balancing).

No:

1. Everybody's requirements are different. You might need an ORM to get a web site up quickly. I might need to avoid using higher-level abstractions to keep my code fast.
2. Node is a platform, not a framework. If you're not building your architecture up from node's standard library, you're not taking full advantage of one of node's greatest strengths, which is its minimalism.
3. There are already pretty broad divides between approaches for building full-stack apps in node. Some people get a lot of value out of Express and or Flatiron, smaller groups have strong preferences for other frameworks like Geddy, Tako, Restify or Strata (not exactly apples to apples comparison there, but you know what I mean, and that's also part of my point). I don't think it's good for us as a community to spend too much time trying to elect any of them as de facto standards.

FWIW, I've been working on a substantial Node project full-time for the last five months, and haven't written a line of browser or front-end code.

PS -- waqasde, PHP and Node.js are both good tools for building LAMP-style applications, but they do take very different approaches to solving the underlying problem. You'd probably want to take a look at Flatiron (with Plates and Stylus or less) or Express (with Jade and Stylus) along with node-mysql and Sequelize and see if the sample code for those tools looks like something you'd enjoy working with.
