你们应该掌握你已经知道的技术。

(其余为IMHO)

I m a fan of Node.js and Java. 然而,如果你选择Node.js的话,你会有一个才智的团队。 虽然从长远来看,它较容易启动,但从长远来看,它更便于真正地沉积。

• No clear winner for framework (Express is the closest)
• Moving target. Libraries change all the time.
• Refactoring in Javascript is a PITA
• Dealing with database transactions is rather difficult (if you need transactions)
• Its easy to accidentally write very dangerous code (miss a "var" and you will have a global variable problem).
• Tracing/Debugging through code can be rather difficult with all the callbacks.
• Reading other people s code (why a talented team is important)

仅仅因为客户的密码与前线相同,也无助于你。 事实上,我常常在玩 no时不知觉。 j 在我混淆了我现有的(图书馆)或客户或服务器代码Im时。

Java在服务器方面有一些巨大优势。

• Established choices: Spring MVC or JAX-RS
• Refactoring is easy
• Reading Java code is easy because of the consistency of the language, static typing and cross referencing IDEs.

Your concern for finding a Java developer over a Javascript developer is becoming less and less of a concern. Besides talented people are/should be language agnostic.

就科学、科学和技术部而言,我也不使用。 Backbone + JQuery +wit post post pitsuff。

I am currently using Exactly the same setup that your question is asking about. I am using Sencha s Ext4 and nodejs to build a massive single page application with lots of grids. We are using sencha architect for most of the UI work, and our database uses PostgreSQL. This setup has a number of advantages and disadvantages.

优点:

• There is no html! This is the biggest advantage of all. HTML is annoying. If you use nothing but the ext components, you rarely have to touch html. The most we ever have to do is tinker with the css a little. Words do not properly describe how great this is. We have successfully eliminated the need to write in a verbose, inconsistent xml derivative.
• It made many of us better javascript programmers. This matters for one reason You can t get rid of javascript no matter what you do, if you are building any kind of web application you will have to write massive amounts of javascript. You might as well embrace it rather than try to disguise it. By hiding or disguising it, you are only compounding the problem. If you learn to write better and more efficient javascript, you only make things better in the end.
• The database library automatically outputs in json! How cool is that? it s going to get turned into json and get read over a rest api anyways. Why not have it automatically give you what you re going to use? And this is coming from Postgres. Postgres barely has support for json on it s own, and this automatically does it for you.
• The entirety of this project is written in only two languages pl/pgsql and javascript. and we are currently looking at replacing pl/pgsql with pl/v8 (a port of v8 to postgresql) I am almost able to program without reading documentation. How awesome is that?

缺点:

• Nodejs isn t all fun & games though. Maby it s just me, but it takes quite a while to read through a npm module before I can even make basic use of it.
• You have to really master javascript to make use of Nodejs. Seriously, Nodejs is not for beginners. I m not saying beginners should stay away from it, I just mean that by the time you learn how to do anything useful in it, you will no longer be a beginner. If you intend on writing anything useful, be prepared to learn javascript in depth.
• Sencha is not exactly free. Obviously it depends on what you are doing with it, but it s the only software we had to pay for.
• Development is not as fast as it seems like it would be. Writing a full CRUD for a table, displaying the grid, refreshing the grid adding buttons and such is still very time consuming. Basically, having really nice UI components has actually slowed us down. Now we have to have panels and modal windows and all the things that a real windowing framework has. before using sencha, things were much simpler. Eveything had limited functionality, thus, it was faster to program. Obviously, this will look better when it s done this way, but who s to say we really need all this stuff?

就业绩而言,情况已经足够快。 我确实可以作比较,但还没有业绩问题。
