问题
I want to be able to define templates once and use them to render html from both the server-side as well as the client-side. (DRY principle and all that)
The API that I'm envisioning is simply this: render(JSON, template) --> html.
I'm using a java-framework (actually Play framwork, but I don't think this is framework specific).
I've read a lot of similar questions, the latest, and most helpful being: Templating language for both client-side and server-side rendering.
I pretty much agree with the author that obvious contenders like: Mustache and Google Closure Templates are not going to cut it. (for reasons see that post)
Requirements:
- MUST: client-side rendering
- MUST: client-side caching of template-files
- NICE: client-side 'compile-once execute many times' of template-file to fast javascript-code
- MUST: server-side rendering
- NICE: native java implementation
I've seen a bunch of posts suggesting the use of Node.js for server-side templating. Although this would definitely work (underscore templates, Handlebarsjs, EJS would all work just fine) I'm struggeling to see how to communicate/combine/integrate Node.js with java, after all it's still the java framework that needs to output the JSON
I've seen posts mentioning some proof-of-concept communicating between a JVM and node.js (over http or using JNDI) . However, no library, let alone battle-tested, seems to be available at the moment.
So to round things up, what client-side templating engine would you suggest that would run in java as well (or with some hoops, can be called from a jvm) ? And if that 'hoop' happens to be Node.js, what ways of communication/ library would you suggest to use?
回答1:
I'm going for Mustache for now and anticipating a java implementation for Handlebars.js. Once that exists, the refactoring-path shouldn't be that steep.
EDIT - april 2012
Ok, updating this for future reference:
- I'm outsourcing server-side templating to Node.js.
- communication between java and node.js implemented using sockets. (see: Sending data from node.js to Java using sockets for where I got the idea)
- Since now I only need a client-lib (or better one that runs in javascript on both client and server-side using node) I can choose more freely. Having become accustomed to Mustache, I've chosen the Hogan parser (by the Twitter guys) ( http://twitter.github.com/hogan.js/ )
100% DRY (even the client-side mixins and i18N-bundles come from the same source. Moreover, Hogan can precompile the templates server-side and open a connection to the client so the client doesn't have to parse the template anymore on first connect.
Is it fast? Lightning...
