Garantueed individual values
|
|
|
|
## Example
|
|
|
|
```js
|
|
var Individual = require("individual")
|
|
|
|
var moduleCache = Individual("__MY_MODULE_CACHE", {})
|
|
|
|
// moduleCache is a individual variable local to this file.
|
|
// It will always be the same value and defaults to {}.
|
|
```
|
|
|
|
This gives you a singleton value by a unique name (it stores it
|
|
as a global variable).
|
|
|
|
## Use cases
|
|
|
|
Your module has an internal cache. If your module is loaded
|
|
twice, (someone didn't npm dedup and has two copies of your
|
|
module) you would have two seperate caches that dont talk
|
|
to each other.
|
|
|
|
Best case your cache is less efficient. Worst case you have a
|
|
cache because the native C++ extension you talk to crashes
|
|
if you instantiate something twice.
|
|
|
|
You need a garantuee that this value is an individual, there is
|
|
only one of it.
|
|
|
|
I use it myself because opening a SockJS websocket to the same
|
|
URI twice causes an infinite loop. I need a garantuee that
|
|
I have an individual value for the SockJS connection so I
|
|
can see whether I already have an open connection.
|
|
|
|
## WHY GLOBALS >:(
|
|
|
|
I can't imagine any other way to do it. I hate it too. Make a
|
|
pull request if you know the real solution
|
|
