node-staticize

Router staticize for express

SUPPORTS:

• expressjs

• sailsjs

USE:

• memory

• redis

Cache:

• api result
• api view/render

Install

npm install node-staticize

Example

To use staticize in you module, simply import it:

var Staticize = require('staticize');

And set it (use memory or redis or others):

var staticize = new Staticize({
  cache : {
    adapter: 'redis',
    options: {
      host: '127.0.0.1',
      port: '6379'
    }
  },
  routes: {
    '/cache2s'    : 2,  // default GET method
    'get /cache3s': 3,
    'post /cache3s': 3,
    'get /foo/:bar': 5, // match /foo/whatever
    '/cacheCors': {
      ttl: 3,
      cors: 'http://yoursite.com' // allow 'http://yoursite.com' CORS access
    },
    '/cacheCorsForAll': {
      ttl: 3,
      cors: '*' // "*" to allow all domains CORS access
    }
  }
});

Then you can create a middleware:

staticize.cacheMiddleware() // set cache seconds, default 0 to skip

Use it:

• expressjs:

app.use(staticize.cacheMiddleware());
app.use('/cache4s', staticize.cacheMiddleware(4));
app.use('/cacheCors', staticize.cacheMiddleware({ ttl: 3, cors: '*' }));

app.get('/*', function (req, res) {
  res.json({
    time: new Date().toLocaleString()
  });
});

app.listen(3000);

• sailsjs:

// create a staticize.js under /policies
...
module.exports = staticize.cacheMiddleware(30);
...

// set it in policies.js
...
  'StaticizeController': {
    'test30s': ['staticize']
  }
...

new Staticize(options)

options.cache

cache config, include:

• options.cache.adapter : type string, such as memory redis ...
• options.cache.options : type object, if not use memory adapter, need to connect to Adapter, for example:

{
  ...
  cache: {
    adapter: 'redis',
    options: {
      host: '127.0.0.1',
  	  port: 6379
	}
  }
  ...
}

if given an unsupported adapter would throw a TypeError :

throw new Error('Unsupported cache adapter: ' + adapter);

[options.routes]

object , key is 'uri' or '${http method} uri' , value is cache seconds.

1. When staticize.cacheMiddleware(30) with a ttl , staticize will use this ttl and NOT search in option.routes .
2. When staticize.cacheMiddleware() with no ttl , staticize will search in option.routes :
   1. First search the 'uri' key, found and return;
   2. Then search the '${http method} uri' key, found and return;
   3. if not, return 0.

API

.cacheMiddleware(cacheTTL, skip, fn)

1. cacheTTL is cache seconds.
2. [skip] is a RegExp, if req.originalUrl.match(skip), goto next().
3. fn is a function of using req to create a extension string adding to cache key.
