Overview

@prostojs/serialize-fn is a utility library for JavaScript and TypeScript that provides functions to analyze and serialize JavaScript functions. It includes tools to check if a function uses only allowed global variables and to serialize a function with its arguments into a string.

Installation

You can install @prostojs/serialize-fn using npm:

npm install @prostojs/serialize-fn

Or using pnpm:

pnpm install @prostojs/serialize-fn

Usage

isCleanFn

This function checks if a given function uses only allowed global variables.

Parameters

• fn ((...args: any[]) => any): The function to check.
• allowedGlobals (string[], optional): An array of allowed global variable names. Default is an empty array.

Returns

• boolean: Returns true if the function only uses allowed globals, false otherwise.

Example

import { isCleanFn } from '@prostojs/serialize-fn'

const myFunction = () => {
  console.log('Hello, world!')
}

const allowedGlobals = ['console']

const isClean = isCleanFn(myFunction, allowedGlobals)
console.log(isClean) // Output: true

serializeFn

This function serializes a given function and its arguments into a string.

Parameters

• fn ((...args: any[]) => any): The function to serialize.
• args (...string): The arguments to pass to the function.

Returns

• string: Returns a string representing the serialized function call.

Example

import { serializeFn } from '@prostojs/serialize-fn'

const myFunction = (name: string) => {
  return `Hello, ${name}!`
}

const serializedFunction = serializeFn(myFunction, "'World'")
console.log(serializedFunction) // Output: return (function (name) { return `Hello, ${name}!`; })('World')
