f-decorator

It implements a function decorator with global object for reflection, including IoC container and env file support.

new globals

• global.own: reflection object
• global.ioc: IoC container object (optional)
• global.env: typed env file, independent of env nodejs

own intropection

• global.own.decorators: all data decorators
• global.own.functions: all functions
• global.own.modules: all modules

object reflection

function Example() {  }

Example.path        // file path of function
Example.async       // true if it returns Promise
Example.module      // module host of Example function
Example.module.use  // check if it is 'client' ou 'server'
Example.decorators  // list all related function decorators

function decorator

Creating a function decorator.

class log extends Decorator {
   constructor(args: LogDecoratorArgs) { super(args) }
   public annotation = () => 'done' // decorator.data
}

Using a function decorator.

@log({ hi: 'it works'})
function Example() { }

Example.decorators[0].name == 'log'
Example.decorators[0].data == 'done'

It is transpiled as below.

const Example = new log({ hi: 'it works'})
   .decorate(function Example() { })
   .target

color syntax issue

To prevent error syntax warning, just use @ts-ignore in typescript projects.

// @ts-ignore
@log({ hi: 'it works'})
function Example() { }
