wrap-module-function
Helper for override module.exports
to do something like middleware or wrap all exported function from all modules in specific path.
For example, logging excutation time for all modules in ./domains/...
directory or logging all function call on every function exported from module in ./utils/...
Installation
npm install --save wrap-module-function
Configuration
Please see more detail example on ./example
const wrapModule = require('wrap-module-function')
// Must be call this before any require module
wrapModule({
debug: false
}, {
// Key is something in path of target module. In this case will match every file in controller directory
'controller': function(exports, named, fullFilePath){
return function(){
// Log everytime controller function called
console.log(`--- controller ${named} involed`)
return exports.apply(this, arguments)
}
},
// Match every module in domain directiory
'domain': function(exports, named, fullFilePath){
return function(){
// Log excution time
const start = Date.now()
const result = exports.apply(this, arguments)
console.info(`--- ${named} excuted in ${Date.now()-start}ms`)
return result
}
}
}
)
