Extract endpoints from OpenAPI YAML file

extract-endpoints.js

const fs = require('fs');
const yaml = require('js-yaml');

function listEndpoints(openapiFile) {
  try {
    const openapiData = yaml.safeLoad(fs.readFileSync(openapiFile, 'utf8'));
    const paths = openapiData.paths || {};
    const endpoints = [];
    
    for (const path in paths) {
      const methods = paths[path];
      for (const method in methods) {
        const endpoint = `${method.toUpperCase()} ${path}`;
        endpoints.push(endpoint);
      }
    }
    
    return endpoints;
  } catch (error) {
    console.error(`Error loading OpenAPI file: ${error}`);
    return [];
  }
}

// Usage example
const openapiFile = 'your-openapi.yaml';
const endpoints = listEndpoints(openapiFile);
for (const endpoint of endpoints) {
  console.log(endpoint);
}

To use this script, replace 'your-openapi.yaml' with the path to your actual OpenAPI YAML file. The script uses the fs module to read the file, js-yaml to parse the YAML data, and then iterates over the paths section to extract the endpoints in the format HTTP_METHOD PATH. Finally, it prints each endpoint.

Make sure you have the js-yaml package installed before running the script. You can install it using npm install js-yaml.
