What is flow-bin?

The flow-bin npm package provides a command-line interface for Flow, a static type checker for JavaScript. Flow helps developers catch common errors early by adding type annotations to JavaScript code.

What are flow-bin's main functionalities?

Type Checking

Flow can be used to add type annotations to JavaScript functions and variables, which helps catch type errors during development.

/* @flow */
function add(a: number, b: number): number {
  return a + b;
}
add(1, 2); // No error
add('1', '2'); // Error: string is incompatible with number

Type Inference

Flow can infer types even if they are not explicitly annotated, providing type safety without requiring extensive type annotations.

/* @flow */
function square(n) {
  return n * n;
}
square(2); // No error
square('2'); // Error: string is incompatible with number

Type Definitions

Flow allows you to import and use type definitions from other files, making it easier to manage and reuse types across a project.

/* @flow */
import type { User } from './types';

function getUser(id: number): User {
  // Implementation
}
