This module is available on NPM:
$ npm install hotfunctionsmanager
For example, if there's a file "hello.js" that contains:
Then, the id of the function will be "hello".
It's on your own to write your functions with a correct syntax, unless the module will crash !
You can also adds functions while the process is running, and decide if this functions will be written to the filesystem or not. Keep in mind that there's a risk of overwritting files and functions if you specifies the same id of two differents functions.
If you've added new functions in the directory, you can analyse the directory once again with the updateFunctionsList() method.
Let's consider that you have a directory "myDirectory", that contains two files: "hello.js" and "goodbye.js". So, you can do the following:
var HotFunctionsManager = ;// Construct your objectvar myFunctions = "./myDirectory";// Here, our object has been built, but our folder hasn't beed read yet// This is triggered by the call of the init() method.// Why ? Because, reading files involves I/O operations that may impact// considerably your application's performances. Please, consider it.myFunctions;// And now, you can call your functionsmyFunctions;// Add a function that will not be written to the filesystemmyFunctions;// Add a function that will be written to the filesystemmyFunctions;// Now let's say that you process has been running for 2~3 days, but// you need to add new features... But, your project is on production// environment, you can't kill the process... What do you do ?!// Well, simply write your features in file, and run the following:myFunctions;// Of course, your process must have predicted this behavior, and must// then, running as a job an execution of all your defined functions// (See myFunctions.getAllIds())
