Advanced tools
Easily create functions with dynamic name and length. This is useful for wrapping functions without f'ing up their name and length.
npm install --save dynamic-function
const dynamicFunction = require('dynamic-function');
function originalFunction(originalArg1, originalArg2) {
/* ... */
}
const wrappedFunction = dynamicFunction(originalFunction, {
name: 'wrapped_' + originalFunction.name,
length: originalFunction.length,
});
console.log(wrappedFunction.name); // logs 'wrapped_originalFunction'
console.log(wrappedFunction.length); // logs 2
console.log(wrappedFunction.toString());
// function wrapped_originalFunction(originalArg1, originalArg2) {
// /* ... */
// }
dynamicFunction ( func [, options] )
func : function options : object (optional) options.bind : object (default: null) options.name : string (default: '') options.length : number (default: 0)
Some environments (eg. NodeJS < 4.x.x) don't support renaming functions with Object.defineProperty
. In this case there is a fallback to eval
.
eval
a relatively slow JavaScript feature. Avoid (over)using this in situations where high performance is required.
At start-up (for Server applications) / low load situations using this should pose no problem.
