require-from-string

What is require-from-string?

The require-from-string npm package allows you to dynamically load modules from a string of code. This can be particularly useful for executing dynamically generated code or loading modules from sources other than the filesystem, such as databases or network responses.

What are require-from-string's main functionalities?

Load module from string

This feature allows you to load a module by passing a string of code to the require-from-string function. The module can then be used as if it were required from a file.

const requireFromString = require('require-from-string');
const code = 'module.exports = { hello: () => "Hello, world!" }';
const module = requireFromString(code);
console.log(module.hello()); // Outputs: Hello, world!

Other packages similar to require-from-string

vm2

vm2 is a sandbox that can run untrusted code with whitelisted Node.js built-in modules. It's more feature-rich and focuses on security by providing a secure environment to execute code, whereas require-from-string simply loads modules from strings without sandboxing or security features.

eval

The eval package is another alternative that allows for execution of code contained in strings. However, it's generally less safe than require-from-string because it executes the code in the global context, which can lead to potential security issues. require-from-string focuses on module loading rather than arbitrary code execution.
